Description

S&S group purchase method {THE METHOD OF SNS GROUP PURCHASE}

How to purchase jointly through SNS.

These days, joint purchases linked with social media sites are gaining popularity.

SNS is an abbreviation for Social Networking Service, and refers to a service that allows you to establish relationships with unspecified people online. Users build new networks or strengthen relationships with existing networks through SNS. A typical example of an SNS site is Twitter or Facebook.

When a certain group purchase site announces that it will proceed with a group purchase that sells products at a fairly large discount rate when the purchase request quantity exceeds a certain quantity for a specific product to participate in the group purchase by acquiring public information on group purchases. In particular, through social media sites such as Twitter and Facebook, site members encourage each other to participate in group purchases.

A representative example of such a group purchase site is Groupon ( http://www.groupon.com ) in the United States, and Ticket Monster (http://www.ticketmonster.co.kr/) in Korea. In Korea alone, there are numerous SNS group purchase sites, including Ticket Monster, and it can be seen that they all saw the success of Groupon in the United States and entered the group purchase business.

As the entry barrier is very low due to the relatively simple method of proceeding with the SNS joint purchase, competition between companies is very fierce, and as a result, many places are shutting down. This is because without any special strategy, they are all operating in almost the same way.

However, there is one big problem in the conventional SNS joint purchase method.

As shown in FIG. 1, group purchase is proceeding so that only one purchase application price to which one discount rate is applied according to one purchase application quantity section exists.

Buyers who apply for purchase through SNS joint purchase expect to be able to purchase at a discount of up to 50%. This is because most SNS group purchase announcements say that if a certain amount of purchase request is applied, it can be traded at a discount of about 50%, and such transactions are also made. In fact, the 50% discount is almost non-existent. It is a price that is difficult to make a profit unless a huge amount is traded.

In such a situation, if the group purchase has to proceed so that there is one purchase application quantity section and one purchase application price as in the conventional method, a 50% discount is applied only when an extremely large quantity that is unlikely to be applied for purchase is requested. If the seller announces that they can trade at the specified price, buyers are likely to criticize them, so from the seller's point of view, the group purchase announcement that they can trade at a 50% discount even if a small quantity is applied for purchase. situation in which it is necessary to That is, in the conventional method, an excessive discount rate is inevitably applied compared to the quantity requested for purchase. In such a situation, even if the quantity requested for purchase satisfies the disclosure conditions and the transaction is concluded, the gross margin is almost No (or lose ) . In other words, the conventional SNS-linked group purchase is not a strategy for great profit due to separation, but it is almost always an announcement of the group purchase for the purpose of promoting the business , and there is no choice but to cause problems in service quality. structure, and the seller cannot frequently make joint purchases. In addition, a seller who sells a product that cannot be discounted by 50% without a huge amount or a seller who does not want to sell even at a 50% discount can even think of proceeding with a group purchase through SNS using this conventional method. can't be

Let's take a closer look at the problem through newspaper articles.

In an interview (Jan. 11, 2011) of Shin Hyun-seong, CEO of Ticket Monster, the No. 1 social commerce company in Korea, the problems of conventional social commerce are indirectly revealed.

“ Nearly 500 websites (= social commerce companies ) have popped up like crazy. Customer dissatisfaction with domestic social commerce services is growing. There are a lot of places that sell poor quality products or close after a short period of business. From this year on, Timon plans to select companies more rigorously and conduct field visits and training. From the perspective of the company, there is also the task of increasing the publicity effect as much as expected when selling goods through social shopping services. We plan to create a new channel for these traders to directly communicate with their customers.”

Looking at the above interview, only the publicity effect is emphasized, and the many benefits of separation are not mentioned at all. However, in most cases, even the publicity effect is insufficient. This is because there are many cases of crowds or wandering customers chasing only low prices. As a result, there are many cases of damage that have caused only huge losses.

And the KBS 'Consumer Complaint' program evaluated it as follows.

" Title: Half-price discount coupon, half-price service?

Social commerce where you can use products or services at discounted prices through group purchases through the Internet! A social commerce site that sells various products such as food, performances, beauty, and education first appeared in Korea in March 2010. The social commerce market is growing rapidly, with coupon sales reaching 60 billion won last year. Consumer cases are also on the rise. If you visit a company with a discount coupon purchased through social commerce, you will be treated differently from regular customers. Is it true?

A steak restaurant I went to to check. The production team divided into a discount coupon customer team and a regular customer team to order the same menu. The dish of the discount coupon customer team that looks weaker than the general customer team at a glance. Not only the amount of meat was different, but also the overall menu was different. Also, in the case of some social commerce companies, they were demanding excessive coupons from service providers. Consumers are unable to receive proper service due to overuse of these discount coupons.

<Consumer Complaint> has covered the problem of 'social commerce', which does not receive proper service due to price discounts."

In addition, there are articles expressing concerns at the Fair Trade Commission as follows due to excessive discounts and operational problems of social commerce companies.

“As the side effects of social commerce became increasingly serious, the Fair Trade Commission began an investigation into the damage situation on the 8th. An official from the Fair Trade Commission said, “We will take measures after identifying the specific situation with a few large-scale companies nationwide.” Previously, the Fair Trade Commission issued a consumer damage advisory related to social commerce in November last year ."

In addition, as there are about 500 social commerce companies in Korea alone as of January 1, 2011 alone, it is expected that there will be at least 10,000 social commerce companies worldwide. It can be said to be the same as Groupon. So, it is also being talked about in the media as follows.

"Social commerce rush, lack of strategy is a problem"

"The problem is found that there is no other strategy other than first-mover."

"If you add your own success factors, you will be able to survive in the market."

Also, there is an analysis that Groupon is highly likely to follow the footsteps of eBay, an online auction company. It is said that the online coupon business is a typical example of the Internet service, which attracted a lot of attention from consumers in the early days, but soon began to lose popularity .

It is argued that the method of the present application is absolutely necessary in the above situation.

Now, as shown in FIG. 1, a problem of the conventional method in which a group purchase is carried out so that only one purchase application price to which one discount rate is applied according to one purchase application quantity section exists will be examined in detail.

For example, as shown in FIG. 2 (or FIG. 4), for a product whose price that is normally sold, that is, the price to which a discount is not applied, is 10,000 won, “150 or more” section, “300 or more” section, “500 or more” Even if you want to proceed with a group purchase so that there are multiple purchase application prices with different discount rates applied to each section of the number of purchase requests including the section,

The group purchase is proceeding so that only one purchase request quantity section including the “500 or more” section of FIG. 1 and one purchase request price to which one discount rate is applied exist.

So, the number of purchase requests for group purchase was, for example, 490 pieces as shown in Fig. 5, and the number of purchase requests that were satisfied with the price only applied with a 30% discount rate rather than a big discount rate of 50% discount rate was 350 pieces. (=40+130+180), even though there were quite a lot of them, the discount suggested in the group purchase announcement such as 500 in Fig. There are many cases where the transaction cannot be completed.

5 or 6, which is described in detail as an embodiment of the method of the present application in the section [Specific Contents for Carrying out the Invention], in a situation where the quantity of 490 purchase requests is applied for purchase, as in the conventional method as in FIG. Although 500 pieces, the lower limit of the purchase request quantity section in the form in which only the purchase request quantity section exists, could not be achieved, according to this method, the purchase request quantity of 350 pieces is possible, but in the conventional method, even one buyer can purchase , giving too much opportunity to buyers or sellers.

In the SNS group purchase, as shown in FIG. 2, obstacles in the group purchase are removed in a reasonable way so that a plurality of purchase application prices to which different discount rates are applied exist.

29. The method according to any one of claims 21 to 28,

In determining the winning bid price,

For each purchase request price, the additional discount is applied at the lowest purchase request price among the purchase application prices corresponding to the fact that the cumulative purchase request quantity applied for purchase over the purchase request price is greater than the lower limit of the purchase request quantity section condition. A method, characterized in that the winning bid price is determined.

[Sudan 30]

30. The method of claim 29,

A method characterized in that the following method is the method of determining the winning bid price by applying an additional discount.

Successful bid price = A - B

A: Purchase request price in the section to which the total purchase request quantity belongs

B : Additional discount amount = C * D/E

In the formula for B,

C is the number (or a number close to it) minus the purchase request price of the next section (toward the larger purchase request quantity) of the section to which the total purchase request quantity belongs from the purchase request price in the section to which the total purchase request quantity belongs.

D is the number (or a number close to it) minus the lower limit number of the section to which the total purchase request quantity belongs from the total purchase request quantity.

E is the number (or a number close to it) minus the lower limit of the section to which the total purchase request amount belongs from the lower limit of the next section of the section to which the total purchase request quantity belongs.

(The above numbers are not fixed numbers, but may be numbers that can be adjusted arbitrarily by a person including a seller or a site operator.)

Group purchase will be conducted so that there are multiple purchase application prices to which a specific discount rate is applied for multiple purchase application quantity sections such as the “150 or more” section, “300 or more” section, and “500 or more” section of Figure 2 in the group purchase through SNS. Being able to do this is to solve the long-cherished dream of sellers, and as long as the total number of purchase requests for group purchase is calculated, a reasonable successful bid price can be determined .

At the same time, it is possible to reduce the opportunity loss that has occurred in the past, to satisfy more buyers and more sellers, and since transactions can be concluded even at a price with a low discount rate applied , sellers can obtain an appropriate margin As a result, the quality of products can be improved, and sellers can frequently make group purchases, so group purchases, especially group purchases with only one vendor, such as group purchases linked to SNS, can be further activated.

Even if a group purchase is carried out to include a purchase request quantity section to which a discount is not applied at all, such as the section “less than 150” in FIG. 4, there are many cases in which the buyer or seller can be satisfied.

The above effects will be described in more detail as follows.

If the group purchase can be disclosed so that there are multiple purchase application prices to which a specific discount rate is applied for each number of purchase application quantity sections as in the present method, as shown in FIG. If it is announced that it can be traded at a price, and that it can be traded at a 15~30% discount for a quantity that is not very large, the buyer also has a 50% discount. There will be no complaints, and even if a small quantity is applied for and a transaction is concluded, the price with a small discount rate applied to a small quantity is determined as the successful bid price, so the seller can see a satisfactory level of gross margin. there will be Therefore, there is no problem in quality, and the seller can frequently make a group purchase. If you look at the 30% discounted price and the 50% discount price from the buyer's point of view, it appears that there is only a 20% difference in price. You may have a margin of 10 times that of selling with So, in Figure 5, if the quantity is 150 or more, a 15% discount, if the quantity is 300 or more, a 30% discount, and if the quantity is 500 or more, a 50% discount. but,

From the seller's point of view, as shown in FIG. 8, 15% discount if the quantity is more than 150, 30% discount if the quantity is 500 or more, and 50% discount if the quantity is 3000 or more. According to the method of the present application, the seller reasonably announces a 15% discount if the quantity is 150 or more, 30% discount if the quantity is 500 or more, and 50% discount if the quantity is 3000 or more. Although it is difficult to obtain a margin and apply for a purchase with a quantity of 3,000 (or from the seller's point of view, a 15% discount if the quantity is 25 or more, a 30% discount if the quantity is 100 or more, and a 50% discount if the quantity is 500 or more, as shown in Figure 9. According to the method of this application, the seller reasonably announces a 15% discount if the quantity is 25 or more, 30% discount if the quantity is 100 or more, and 50% discount if the quantity is 500 or more. A considerable gross margin can be obtained, and it is difficult to apply for a purchase for a quantity of 500, but) even then, a considerable gross margin can be obtained and the seller can be satisfied, whereas, as in the conventional method, one purchase according to the quantity If there is no choice but to disclose the group purchase so that only the application price is respected, if it is only announced that a 50% discount is given if the quantity is more than 3000, the quantity of 3000 is too large. For fear of being criticized by buyers for disclosing only for promotional purposes rather than sales, the seller announces that the product can be traded at a 50% discount if the quantity is more than 500. Even if a transaction is made at a price, there is not much margin for the seller, so it is difficult for the seller to be satisfied with the margin, and there are many cases where only the publicity effect can be expected from exposure to a popular group purchase site. And, in fact, in most cases, the publicity effect is insufficient. This is because they are often a group of people who are only chasing low prices.

In addition, although it is still active that only products in the service field are distributed by the social commerce method collective purchase method, using the method of the present application, it is possible to activate the social commerce method collective purchase of industrial products as well.

In fact, because industrial products cost a lot of material and often have low margins from the beginning, there are very few industrial products that can be sold at a discount rate of about 50%.

In such a case, as in the method of the present application, various kinds of industrial products can be distributed in a social commerce method only when various stages of discount rates are presented.

And, so that the price does not change even if the purchase request quantity section is changed, or there is a section in which the price change is very insignificant, the purchase application benefit is matched for each purchase request quantity section. It is no longer a factor in deciding whether to choose the application benefit, so products with a paid price are useful, but it is more useful for products that are free from the beginning, such as insurance, internet subscription, and mobile phone subscription products, and only require a contract. It can be made more profitable for the seller in terms of margin.

15. Payment later: After the successful bid price has been determined , the payment is made after the purchaser pays the purchase cost, the purchase deposit, or the seller pays the sales deposit after any outcome of the group purchase is made.

16. Purchase cost reflecting the purchase request price: This is the purchase cost calculated by multiplying the purchase request price by the purchase request quantity (eg, number of people, number or number of times).

Furthermore, the concept can be expanded to an amount that also considers 'variable costs', which will be described later.

17. Purchase cost with successful bid price reflected: This is the purchase cost calculated by multiplying the successful bid price by the number of purchase requests (eg, number of people, number, or number of times).

Furthermore, the concept can be expanded to an amount that also considers 'variable costs', which will be described later.

And, since variable benefits are included in all benefits mentioned herein, or are additionally automatically or procedurally calculated, the variable benefits are actually considered or should be considered even if they are not mentioned individually. Rather, it is not because the sentences of the present application become cluttered, which may interfere with understanding the essence of the present application. Or, by saying '(considering variable benefits)', we insert the phrase about variable benefits in parentheses, and proceed with the sentence so that we don't pay much attention to those phrases.

20. Refund: It means returning part or all of the amount paid in advance, including refund.

**********End of term definition.

For easy understanding of the present application, an embodiment will be described.

Although the example is given for a service product called food, it is self-evident that industrial products are also possible.

At a certain restaurant, steak A is usually sold for 10,000 won.

By the way, suppose that a group purchase event was held for a stake A on a certain group purchase site, and the group purchase was announced while stating the group purchase conditions as shown in FIG. 4 .

It is assumed that many buyers apply for group purchase after reviewing the group purchase conditions as shown in FIG. 4 .

When applying for a purchase for a group purchase by the method according to the present application,

As each buyer thinks, he/she makes a purchase request while expressing his/her own purchase request price and purchase request quantity, that he will fulfill his/her purchase at a certain price.

(Of course, when each buyer applies for purchase, it is also possible to apply for purchase while saying that he will purchase two or more products.)

The purchase request price from the buyer's point of view is the maximum price that the buyer can accept the purchase.

For example, applying for a purchase at a purchase request price of 7,000 won means

If the winning bid price exceeds 7,000 won, we will not purchase,

They expressed their intention to carry out the purchase as long as the winning bid price is less than 7,000 won.

In addition, while applying for purchase, even though the successful bid price has not yet been determined, the purchase cost is paid for each purchaser in which the expressed purchase application price is reflected.

There are various payment methods. Examples of payment methods include deposits, reserves, various points, credit cards, account payments, and mobile phone payments. There are different ways to get reimbursed accordingly. In addition, since such a payment system can be easily implemented by an ordinary e-commerce engineer, it will not be described in detail.

If, it is assumed that the result of the purchase application in the group purchase announcement as shown in FIG. 4 is as shown in FIG. 5 below.

It should be noted that the quantity of products expressed as numbers below also includes the quantity of uncountable service products including beauty salon services and nail care services. For example, even if the number of services is expressed as a number, there will be no difficulty in understanding the method of the present application.

Although the following embodiments have been mainly described using the number, it will be apparent to anyone that the same principle is applied to a product requiring the number of people or the number of times, so it will not be described in detail.

Referring to Figure 5,

A total of 490 products were applied for for group purchase, and among those 490 products,

There were 40 purchase requests at the purchase request price of 10,000 won,

At the purchase request price of 8,500 won, there were 130 purchase requests,

At the purchase request price of 7,000 won, there were 180 purchase requests,

It can be seen that there were 140 purchase requests at the purchase request price of 5,000 won.

Regardless of the number, it is unconditionally possible to purchase at 10,000 won, which is the price at which the usual price discount is not applied.

(For a little more detail,

If it is less than 150, it is announced that it will be supplied at the usual price of 10,000 won. As the cumulative number of purchase requests at the purchase price of 10,000 won is 40, the lower limit of the “purchase request quantity section” in that line is, in fact, 1 Since it is an individual, it can be seen that the transaction can be concluded at the usual price, so the “satisfaction” column in the “less than 150” row of the “purchase request quantity section” column is “satisfied”).

If there are more than 150, it is announced that the product will be supplied at KRW 8,500, which is the price at which a 15% discount is applied. Since it is 150 pieces, it can be seen that the transaction can be concluded at a 15% discount price, so the “satisfaction” column in the “150 or more (=150~299)” row of the “purchase application quantity section” column is “satisfied” "ego,

If it is 300 or more, it is announced that it will be supplied at 7,000 won, which is the price at which a 30% discount is applied. It can be seen that the transaction can be concluded even with a 30% discount price, so the “satisfaction” column in the “300 or more (=300~499)” row of the “purchase request quantity section” column is “satisfied” ego,

If it is 500 or more, it is announced that it will be supplied at 5,000 won, which is the price at which a 50% discount is applied. Since it is less than 500, it can be seen that the transaction cannot be concluded at the 50% discount price, so the “satisfaction” column of the “500 or more” row of the “purchase request quantity section” column is “dissatisfied”.

There may be two methods for determining the successful bid price in the state described so far.

The first way is

For each purchase request price, a purchase request corresponding to a section in which the cumulative purchase request quantity applied for purchase above the purchase request price is greater than the lower limit of the purchase request quantity section condition (where the successful bid price can be determined based on the purchase request price) The lowest purchase request price among the prices is determined as the winning bid price .

(In this way, eventually) 7,000 won, the lowest price among the 10,000 won, 8,500 won, and 7,000 won, which is the purchase request price corresponding to the purchase request quantity section in which the “satisfaction” column is “satisfied,” becomes the winning bid price.

In addition, 350 pieces, which is the cumulative total of all purchase requests at the purchase request price of 7,000 won or more, which is the successful bid price, can be traded at the same price of 7,000 won, which is the successful bid price.

in other words,

A purchaser who applied for a purchase at the purchase request price of 10,000 won will also be able to purchase it at 7,000 won,

A buyer who applied for a purchase at the purchase request price of 8,500 won will also be able to purchase it for 7,000 won.

Of course, a buyer who applied for a purchase at the purchase request price of 7,000 won will also be able to purchase it at 7,000 won.

When it comes to being able to purchase, it can be expressed as passing the purchase application, or it can be expressed as a purchase conclusion, but they all mean the same thing.

In addition, 140 purchases requested at the purchase request price of 5,000 won, which is less than the successful bid price of 7,000 won, become impossible to purchase. The statement that the purchase becomes impossible will be expressed as failing to pass the purchase application, or it will be expressed as not being able to conclude the purchase, but they all mean the same thing.

And, when applying for a purchase, even before the successful bid price is determined for each buyer, the purchase price was paid in advance as much as the purchase cost reflecting the purchase application price in consideration of the amount obtained by multiplying the purchase application price by the purchase application quantity,

Buyers who have become unable to purchase may be refunded the amount they paid in advance at the time of application for purchase, and the product may not be supplied.

To a buyer who has become available for purchase, the product may be supplied while refunding the amount obtained by deducting the purchase cost with the successful bid price reflected (= the successful bid price multiplied by the purchase application quantity) from the amount paid in advance at the time of the purchase application.

To elaborate a little more,

The purchaser who applied for a purchase at the purchase request price of 5,000 won, which is lower than the successful bid price of 7,000 won, and applied for purchase for 140 pieces for which 5,000 won was paid in advance, 5,000 won for each pre-paid piece is refunded, and the product is not supplied .Because the purchase application at a lower price than the successful bid price has made it impossible to purchase, the entire amount paid in advance is refunded.

The difference between the pre-paid amount of 7,000 won per piece and the successful bid price of 7,000 won for the buyer who applied for a purchase for 180 units who paid 7,000 won in advance while applying for a purchase application price of 7,000 won, which is the same amount as the successful bid price 0 won per person is refunded, and the product is supplied. In other words, 0 won, which is the difference between the successful bid price and the amount paid in advance, means that there is no refund.

Buyers who applied for a purchase with a purchase request price of KRW 8,500, which is higher than the successful bid price of KRW 7,000, and applied for purchase of 130 units for which KRW 8,500 was paid in advance, will receive KRW 8,5,000 per piece and KRW 7,000 for each successful bid. The product is supplied with a refund of 1,500 won each, which is a cost that differs from the product.

Buyers who applied for a purchase at a purchase request price of KRW 10,000, which is higher than the successful bid price of KRW 7,000, and applied for a purchase for 40 units for which KRW 10,000 was paid in advance, will receive a discount of KRW 10,000 per unit and the successful bid price of KRW 7,000. The difference in cost, 3,000 won each, is refunded, and the product is supplied.

The second method is a slightly improved method of the first method,

For each purchase request price, purchases corresponding to a section in which the cumulative purchase request quantity applied for purchase above the purchase request price is greater than the lower limit quantity of the purchase request quantity section condition (where the successful bid price can be determined based on the purchase request price) This is a method in which a specific price among the prices below the lowest purchase application price among the application prices is determined as the winning bid price.

Simply put, it is a method in which an additional discount can be applied from the successful bid price according to the first method.

A great variety of methods, ie, an infinite number of methods, can be devised depending on the idea of additional discount methods.

Regarding the additional discount limit, the price after the additional discount is greater than or equal to the purchase application price corresponding to the next purchase application quantity interval in the segment to which the successful bid price by the first method belongs (toward the larger purchase request quantity) recommend that In the following example, it means that it is recommended that the price after additional discount is 5,000 won or more. If there is no additional discount, for example, if the total number of purchase requests is 500 or more in FIG. 5, there may be no additional discount or a separate additional discount method may be applied.)

To explain one of the various methods in which additional discounts are applied as an example,

According to the first method, a 30% discount is applied whether it is 300 or 499, but

According to the second method here, 30% discount is applied to 300 pieces, 49% discount is applied to 490 pieces, and so on.

So, even if a certain buyer applies for purchase at 7,000 won, if the total number of purchase requests is 490, a 49% (about) discount can be made so that about 5,100 won becomes the successful bid price.

To elaborate a little more,

Successful bid price = A - B = 7,000-1,900=5,100 won

In the above winning bid price calculation formula,

A is the purchase request price (=7,000 won) in the section to which the total purchase request quantity (490 pieces) belongs,

B is the additional discount amount (1,900 = 2,000 X 190/200).

In the formula for B,

2,000 is the number obtained by subtracting the purchase request price of 5,000 won for the next section (toward the larger purchase request quantity) of the section to which 490 pieces belong from the purchase request price of 7,000 won in the section to which 490 items belong.

190 is the number obtained by subtracting 300, the lower limit number of the section to which 490 belongs, from the total number of purchase requests (490).

200 is the number obtained by subtracting 300, the lower limit of the section to which 490 silvers belong, from 500, which is the lower limit of the next section of the section to which the total purchase request quantity (490 pieces) belongs.

Those of ordinary skill in the art can easily come up with another additional discount method different from the additional discount method of the above embodiment, so another method will not be enumerated any more.

(However, to introduce another additional discount method,

Among group buyers, customers who apply for purchase in large quantities (eg 20 pieces) will have the successful bid price determined by a price additionally discounted by a certain amount or a certain percentage from the purchase application price corresponding to the section including the total purchase request quantity. may be,

The successful bid price may be determined by the purchase application price corresponding to the next section in which the purchase request quantity is larger than the section in which the total purchase request quantity is included.

However, if the additional discount rate in this way is too large, the effect of the discount may be diminished even with group purchases with unspecified people. In any case, an additional discount can be given differentially according to the contribution level.)

When applying for purchase in a large quantity, you can apply for a purchase with the ID of one specific person, but you can have each buyer express themselves as a person who promotes joint purchases with a buyer of a certain ID.

If the seller permits, purchases that can be determined by the purchase request price for each purchase request price, which is a successful bid price that is not possible with the current cumulative purchase request quantity A price below the purchase request price corresponding to a section smaller than the lower limit quantity of the requested quantity section condition may also be determined as a successful bid price.

And Facebook, an American social network company, has already provided a promotional feature that lets my friends know that I paid with Facebook credit and gives me a discount if my friends make a purchase again. You can also give discounts in a similar way.)

Also in the second method, if, when applying for a purchase, before the successful bid price is determined for each buyer, the purchase application price, which is the amount obtained by multiplying the purchase application price by the purchase application quantity, was paid in advance as much as the purchase cost reflecting the purchase application price,

Buyers who have become unable to purchase may be refunded the amount they paid in advance at the time of application for purchase, and the product may not be supplied.

The purchaser who is able to purchase may be refunded the amount excluding the purchase cost reflecting the successful bid price (= the successful bid price multiplied by the purchase application quantity) from the amount paid in advance at the time of the purchase application, and the product may not be supplied.

To elaborate a little more,

Refund of 5,000 won for each of 140 pre-paid units for which purchases were made at a purchase request price of 5,000 won, which is lower than the successful bid price of 5,100 won according to the second successful bid price determination method However, the product is not supplied. This is because the purchase request at a lower price than the successful bid price makes it impossible to purchase, so the entire amount paid in advance is refunded.

For 180 units that paid 7,000 KRW in advance while applying for a purchase at the purchase price of 7,000 KRW, the purchaser who applied for purchase will receive a refund of KRW 7,000 per unit and KRW 1,900 each, which is the difference between the amount paid in advance (KRW 7,000) and the successful bid price of KRW 5,100 each As a result, the product is supplied.

Buyers who applied for a purchase with a purchase application price of KRW 8,500, which is higher than the successful bid price of KRW 5,100, and applied for purchase of 130 units for which 8,500 KRW was paid in advance, will receive 8,5,000 KRW, which is the pre-paid amount, and 5,100 KRW, which is the successful bid price. The product is supplied with a refund of 3,400 won each, which is a cost difference between the two.

A buyer who applied for a purchase with a purchase request price of 10,000 won, which is higher than the successful bid price of 5,100 won, and applied for a purchase for 40 pieces for which 10,000 won was paid in advance, the amount paid in advance, 10,000 won per piece, and the successful bid price of 5,100 each The difference in cost, 4,900 won each, is refunded, and the product is supplied.

When the group purchase proceeds with methods that can be derived from the method of the present application, including the method of the above embodiment with the method of determining the successful bid price by the first method and the second method as described above or the refund concept accordingly,

Even with a small discount rate, there are many cases where the purchase is possible only for satisfied buyers, so that the opportunity loss of the buyer and the seller is reduced.

If, as in the prior art, there is a sale announcement that the product will be supplied at a 50% discount only when more than 500 products are applied for, there is no single buyer who can purchase even after 490 products have been applied for.

According to the method of the present application, 350 out of 490 purchase requests can be traded, so it can be seen that the conventional method has a great opportunity loss for buyers and sellers compared to the method of the present application.

In addition, even though the purchase request price is larger than the successful bid price, the purchase can be made with the same amount of the successful bid price. There is no need to apply for purchase only at the purchase request price.

For example, a buyer who is satisfied with the 15% discount may apply for a purchase at the 15% discounted purchase price, but the winning bid price may be decided at the 30% or 50% (or other discount rate) discount. You can apply for purchase while looking forward to it. If the 30% or 50% (or other discount rate) discounted amount is determined as the successful bid price, the 30% or 50% (or other discount rate) discounted amount even though the person applied for a purchase at the 15% discounted purchase price because it will be available for purchase.

Even if there is no discount, a buyer who is satisfied with the price that was not discounted, who was going to purchase anyway, applies for the purchase price at the price that is not discounted at all, but 15%, 30%, or 50% (or other discount rate) is discounted You can apply for a purchase with the expectation that the winning bid price may be decided at the amount that has been paid. If the discounted amount of 15%, 30%, or 50% (or other discount rate) is determined as the successful bid price, the 15%, 30%, or 50% (or other discount rate) ) will be available for purchase at a discounted price.

In the end, when applying for group purchase according to the method of this company, all you need to do is apply for a purchase at a price at which a discount rate that is roughly satisfactory to you is applied. Only the buyer has to apply for a purchase at a very low price with a very high discount rate applied.

Buyers themselves can focus more on publicity to attract more buyers.

And, as shown in the following Figure 6, “dissatisfaction” occurred in the section where the number of purchase requests was “150 or more”, but even if “satisfaction” occurred in the section where the number of purchasers was “300 or more”, the “satisfaction” column was “ It is not necessary to explain that the purchase request price of 7,000 won, which is the lowest price among the purchase application prices corresponding to the “satisfactory” purchase request quantity section, becomes the successful bid price for the section with “300 or more”.

At the initial time of applying the method of the present application, conventionally, group purchase has been carried out so that only one purchase application quantity section and the purchase application price correspond. If it exists, buyers may not readily accept it or it may cause confusion,

First, it is recommended to proceed with the group purchase so that there are two purchase request quantity sections as shown in FIG. 21, and it is recommended to gradually increase the purchase request quantity section.

This is because, compared to the situation in which only one purchase request quantity section exists, just making two purchase request quantity sections exist can have a huge effect.

For reference, if each purchaser applies for purchase without expressing his/her own purchase application price and quantity of purchase requests,

A group purchase is carried out so that there are multiple purchase application prices to which different discount rates are applied for each number of purchase request quantity sections, such as the “150 or more” section, “300 or more” section, and “500 or more” section in FIG. 2 (or FIG. 4). I'll explain why I can't.

Assume that a number of purchasers have obtained the public information on the progress of the group purchase as shown in FIG. 2, and a total of 470 purchase requests as shown in FIG.

Each buyer, if the bid price at the time of purchase application as long decided how much of the price or less without representations hagetdaneun fulfill Buy, That is, each buyer from a variety of purchase application rates in the joint purchase information disclosed, including two self It is assumed that a purchase request is made without selecting a purchase request price at a satisfactory level, only hoping that a large number of purchase requests will be made by many buyers.

Then, a problem arises that the selling price cannot be determined even though the total number of purchase requests is calculated after the group purchase application is closed. Let's find out why.

The total number of purchase requests, 470 pieces, belongs to the “300 or more (=300-499)” purchase request quantity section in the group purchase announcement. There is no problem when the transaction is completed completely by paying in KRW, but it is not possible.

This is because the psychological state of each buyer who applied for purchase of 470 may be the same as in FIG. 3 . (FIG. 3 shows only the psychological state at the time of the purchase application, not that the purchasers actually applied for purchase while selecting their respective purchase application prices.)

Referring to Figure 3, out of 470 total purchase requests, 180 were applied for purchase with the price of 5,000 won per piece applied with a 50% discount rate in mind. This purchase is expected to be cancelled.

Since each buyer did not select his/her own purchase request price at the time of purchase application, in actual circumstances, the seller or each purchaser does not know that they analyzed the psychological state as shown in FIG. do not know You can only find out after the deadline for each buyer to express their intentions as to whether to conclude a purchase at a successful bid price of 7,000 won per piece or to cancel the purchase.

After the deadline for expression of intention has passed, the number of purchase requests for 180 purchase requests has been canceled with the purchase request price of KRW 5,000 per unit in mind, leaving the remaining number 290 (=470-180), and 290 items are publicly announced for group purchase. Since it belongs to the range of “150 or more (=150-299)” purchase request quantity, the successful bid price is readjusted to 8,500 won with a 15% discount rate applied.

(However, some buyers often do not readily accept the readjustment of the winning bid price. Because some buyers think that, anyway, the winning bid price should be 7,000 won because the number of purchase requests is 470 in the first place. However, from the seller's point of view, the successful bid price should be 8,500 won with the remaining 290 purchase requests, and the margin is too small to sell at 7,000 won (the successful bid price becomes 7,000 won). Or, it is judged that there is a risk of loss, so this joint purchase is not an event that occurs too often.)

And, (even if it's actually very difficult to overcome this situation with fast-paced online purchases, but only if it is agreed to overcome this situation)

Buyers who have applied for the purchase of 290 pieces should try to collect the expression of intention of each purchaser as to whether to conclude a purchase contract at a successful bid price of 8,500 won or cancel the purchase.

It is practically impossible to understand each buyer's will again like this, but in any case, after the deadline for expressing an opinion once again,

Of the 290 purchase requests, 140 pieces were accepted with a purchase request price of KRW 8,500 per unit in mind, and a successful bid price of KRW 8,500 was accepted. As the purchase request quantity of pcs is canceled, the remaining quantity becomes 140 (=290-150), and 140 does not belong to the section of “150 or more (=150-299)” in the group purchase announcement, from the seller's point of view There are too many cases in which the company refuses to sell even at KRW 8,500 with a 15% discount rate applied. Therefore, there are many cases where it is impossible to publicize the joint purchase so that a plurality of purchase application quantity sections exist as shown in FIG. 2 .

2 shows that there are three purchase application quantity sections suggested by the seller, so it is only necessary to converge each buyer's expression of intent on the initial successful bid price or the changed successful bid price twice. If the group purchase announcement is made so that there are the number of purchase application quantity sections, the more the number of purchase application quantity sections, the more the number of times to converge the expression of intent increases. it becomes impossible to do

In this way, as shown in Figure 2, the group purchase is announced so that a plurality of purchase application quantity sections are included, and when each purchaser applies for a purchase, each purchaser applies a purchase request without selecting a purchase application price that is roughly satisfactory to him or her.

It is also virtually impossible to collect from each buyer an expression of intent on whether to conclude a purchase or cancel the purchase at the initial successful bid price or the changed successful bid price several times, and it is also practically impossible for each purchaser to It is inconceivable that each buyer pays the purchase price or the purchase deposit in advance, reflecting the purchase application price, which is the maximum amount that each buyer can pay for the purchase of the product before the price is decided.

Note that, when each buyer to apply jointly to purchase, each buyer's self is the reason for possible progression to joint purchasing have the approval as while expressing a price that satisfied if the how much the price of the Doctors' bid gagyeokga before they decide "the price I'll find out.

At first glance, it seems that there is no difference between paying as much as the successful bid price after the successful bid price is determined or paying before the successful bid price is determined. There is not.

Buyers may be puzzled about paying a price that is satisfactory to them even before the winning bid price is decided.

From the seller's point of view,

After the successful bid price is determined, the probability that there will be a purchaser who does not pay among the purchasers who have applied for a group purchase

Before the successful bid price is determined, that is, when applying for a group purchase, after each buyer has paid a price that is satisfactory to them, among the buyers who have applied for a group purchase, the probability that there will be a buyer who cancels the payment

Because it is much larger.

In other words, there are cases in which the intention to purchase decreases between the time of application for group purchase and the time when the successful bid price is decided, or it becomes cumbersome to visit the site once again to make a payment, or when the payment deadline is missed or cannot be paid. to happen a lot because of.

From the buyer's point of view

It is also quite cumbersome to visit the site once again to make a payment after the winning bid price is decided.

Buyers who impulsively engage in group purchases even just a little by looking at the high discount rate are very likely to avoid payment.

However, if you paid at the time of purchase, the probability of canceling the payment you made anyway is relatively low.

The e-commerce system 10 for the implementation of the group purchase method according to the present invention includes one or more purchase application terminals 12 that can be used for purchase application by an unspecified number of purchasers, or (mainly one person (or one company)) may use) a sales application terminal 18, or a group purchase server 16 operating an online site where group purchase is performed, or a network communication network 14 including the Internet for communication.

(In entering sales information,

The site operator may receive the sales information from the seller, and the site operator may input the sales information through the terminal used by the site operator, or the seller may directly input the sales information through the sale application terminal used by the seller.

If the seller directly inputs sales information through the sales application terminal used by the seller, the sales application terminal 18 used by the seller may be required. If the site operator receives the sales information from the seller and inputs the sales information through the sales application terminal used by the site operator, it may be said that the sales application terminal 18 used by the site operator is necessary. Anyway, it can be said that the sales application terminal is necessary.)

The purchase application terminal 12 connects the purchaser to the group purchase server 16 to check the group purchase progress information, and when the purchaser wants to purchase a specific item they want through group purchase, input their purchase application information or It is a client terminal used to receive purchase progress information.

The sales application terminal 18 is a client terminal used by a seller to access the group purchase server 16, input information on their group purchase condition, and check group purchase progress information.

Group purchase proceeding If the group purchase conditions are entered in such a way that the site operator directly inputs the group purchase condition information after the site operator receives the information on the group purchase conditions from the seller, the seller may not need a sales application terminal. However, if the terminal of the site operator is regarded as a sales application terminal, it may be said that the sales application terminal 18 is necessary.

The group purchase server 16 operates an e-commerce site according to the group purchase method, provides group purchase progress information, receives and stores purchase application information from the purchase application terminal 12, and also stores the purchase application information through the sale application terminal 18 ) receives and stores group purchase announcement information (or sales information), and processes the group purchase progress process.

In addition, since the group purchase method according to the present invention includes a process in which the group purchase server 16 receives and refunds the amount in advance from the buyer or seller, the group purchase server 16 includes a separate payment server (not shown) and It may be implemented to be linked or to perform a payment function by itself, and the group purchase server 16 may be linked with a separate sales server (not shown) to provide information on products to be sold.

The e-commerce system 10 is very similar to the conventional e-commerce system for a general social commerce group purchase shopping mall, internet shopping mall, and internet auction site. Only the operation program provided on the side of the group purchase server 16 needs to be changed, and those skilled in the art will be able to smoothly implement the present invention within the scope of conventional e-commerce system construction technology without explaining the gooji system in more detail.

The group purchase method according to the present invention is a group purchase method in an e-commerce transaction that is performed for the same product at the same processing time, and a seller (mainly, one person) and one or more (mainly many) purchasers can participate, and each purchaser Apply for purchase by inputting purchase application information including the purchase application price corresponding to the maximum price that can be paid for the product subject to purchase within the available purchase application time and the purchase request quantity, which is the quantity of the desired product.

The purchase application status including the purchase application quantity for each purchase application price or the cumulative purchase application quantity for each purchase application price applied for purchase above each purchase application price through the group purchase server is aggregated through the group purchase server,

After the group purchase application ends, through the group purchase server,

For each purchase request price, the purchase request price corresponding to a section in which the cumulative purchase request quantity applied for purchase over the purchase request price is greater than the lower limit of the purchase request quantity section condition (where the successful bid price can be determined based on the purchase request price) Among the prices below the lowest purchase request price, the specific price is determined as the winning bid price,

The result of the transaction, including that the purchaser who applied for the purchase request price higher than the successful bid price is determined as the purchaser who concluded the purchase, and the purchaser who applied for the purchase application price that is less than the successful bid price is determined as the purchaser who did not conclude the purchase It is provided or notified to the connected terminal including the sale application terminal.

Therefore, unlike the conventional group purchase method, there may be purchasers who are determined to be uncontracted purchasers because there are purchasers who have concluded purchases.

The purchaser can guarantee his/her purchase application by inputting purchase application information including his/her purchase request price and purchase request quantity and paying some or all of the purchase cost in advance while applying for purchase. In (16), after the successful bid price is determined, for a buyer who cancels a purchase application even after a purchase has been concluded, part or all of the amount received in advance is returned in the form of a purchase cancellation penalty and paid to the sellers. Seller's loss due to cancellation shall be compensated.

In this way, it can be guaranteed that all purchasers who have applied for purchase will surely execute the purchase.

Of course, the group purchase server 16 immediately refunds the amount received in advance when the purchaser who has paid in advance is determined to be a purchaser who has not been able to conclude a purchase according to the result of the group purchase, while the purchaser who has paid in advance is converted to a purchaser who has concluded a purchase later. If it is decided, the amount received in advance is replaced with the purchase cost of the product, but the difference in cost paid in advance in excess of the purchase cost reflecting the successful bid price is calculated and refunded.

In addition, if the seller also pays a predetermined sales deposit in advance and cancels the sale even after the successful bid price is determined or does not smoothly transfer the product to the buyer, the group purchase server 16 recovers the sales deposit paid in advance to purchase By providing to the contracted buyers, it is possible to compensate for the loss of the buyer due to the seller canceling the sale, and also to secure the reliability of the transaction.

In addition, according to the present invention, the group purchase server 16 does not conclude a transaction at the purchase application price requested by each purchaser, and all purchasers determined as the purchaser concluded can purchase the product at the same price as the successful bid price. Therefore, it is possible to satisfy a large number of buyers as much as possible through a single joint purchase. ( It can prevent even one dissatisfied buyer from occurring.)

In this regard, the group purchase server 16 basically receives the purchase cost calculated in consideration of the purchase application price and the purchase application quantity requested by each purchaser before the successful bid price is determined (mainly, at the time of purchase application). Therefore, the difference between the purchase cost paid in advance by each buyer and the purchase cost with the successful bid price reflected at the time after the conclusion of the purchase contract is calculated and refunded for each buyer.

The group purchasing method according to the present invention consists of the following steps (or means).

(Step (or means) of transmitting group purchase announcement information including that the purchase application price corresponds to each of two or more purchase application quantity sections with respect to the transaction target product to the group purchase server;)

- In this step (or means), as shown in FIG. 4, for a specific product, a group purchase condition including that different purchase application prices to which different discount rates can be applied for each section of two or more different purchase application quantities are matched. It is a step (or means) provided to the site operator and input by the site operator or directly input by the seller.

It is self-evident that different purchase application prices are considered to correspond even if different purchase application prices do not correspond to different purchase application quantity sections in the group purchase announcement, and a specific discount rate compared to different normal prices is corresponding. belong to the scope of the right. This is because, when a discount rate is applied to the normal price, a discounted price is derived.

Through the group purchase server, group purchase announcement information including that the purchase application price (to which a specific discount rate can be applied) corresponds to each of two or more purchase application quantity sections for the product to be traded is transmitted to the purchase application terminal (or sales application terminal: SS ?) to the connected terminal including accepted step (or means)

- In this step (or means), as shown in FIG. 4, for a specific product, a group purchase condition including that different purchase application prices to which different discount rates can be applied for each section of two or more different purchase application quantities are matched. It is a step (or means) of providing to the site operator so that the group purchase disclosure information entered by the site operator or directly entered by the seller can be displayed on the purchase application terminal.

When a specific discount rate is applied to two or more purchase application quantity sections, it is recommended that different discount rates be used for each purchase request quantity section.

And, the specific discount rate may be 0%. That is, there may be a purchase request quantity section to which the normal price is applied.

Either one of the two or more purchase application prices is selected and entered from the purchase application terminal used by each purchaser, or the entered Purchase application information including that is input and transmitted to the group purchase server (It has been stored in the group purchase server: SS ?) step (or means) of becoming

- In this step (or means), after connecting to the group purchase server 16 through the purchase application terminal 12 used by each purchaser, the group purchase announcement information on the products for sale provided by the group purchase server 16 is displayed. If you want to purchase through group purchase by selecting a specific product, enter the purchase application information including the desired purchase application price and purchase application quantity within the available purchase application time, the purchase application information is sent to the group purchase server (16) can be transmitted and stored.

At this time, each purchaser may directly input a desired purchase application price, or from among a plurality of purchase application prices provided by the group purchase server 16 as in the description given for the example through FIG. 4 or FIG. 5 above. You can also select any one to enter.

There are various input methods for selection, including inputting the provided purchase request price numbers one by one, or clicking a button related to the provided purchase request price numbers to enter them.

Selecting and inputting any one has been described in detail with reference to FIG. 4 or FIG. 5 above, so I will end the description here with this.

In addition, if the quantity of the purchase application is one, the quantity of the purchase application may be automatically processed as one without separately inputting the quantity of the purchase application. That is, for a specific purchase application quantity including a case where the purchase application quantity is 1, the purchase application quantity may be automatically entered and processed without separately inputting the purchase application quantity.

In addition, each purchaser may operate so that the purchase application price that he/she applies for purchase can be changed until the successful bid price is determined. As an example of the method of change, it is possible to change only by selecting a new purchase application price, or to cancel a previous purchase application and apply for a new purchase with a new purchase application price. If payment is made in advance at the time of purchase application, additional payment or refund may be made according to the changed price settlement rules.

A portion of the purchase cost in which the purchase application price is reflected before the successful bid price including the time when purchase application information is received from each purchase application terminal through the group purchase server or at the cost of all purchases. If the payment is accepted in advance (taking into account the variable cost) Step (or means)3

- In this step (or means), each purchaser guarantees his/her purchase application by paying in advance all or part of the purchase cost according to the purchase application price and the quantity requested by each purchaser (taking into account the variable cost) It is a step (or means) to do.

If the buyer does not pay the purchase cost in advance before the successful bid price is determined (mainly at the time of purchase application), the purchase application may be canceled later without any restrictions and damage to the seller. In the case of cancellation, a partial amount is paid in advance in the form of a cancellation penalty or to strongly express the intention to purchase.

The purchase application status including the purchase application quantity for each purchase application price or the cumulative purchase application quantity for each purchase application price applied for purchase above the purchase application price at each purchase application price through the group purchase server is displayed on the group purchase server Step (or means) to be aggregated through

- In this step (or means), the group purchase server 16 aggregates or to provide.

Here, the cumulative purchase request quantity for each purchase request price refers to the total quantity of all purchase application quantities applied for purchase at a price higher than the purchase application price.

For example, the group purchase server 16 may provide the purchase application status including the accumulated purchase application quantity displayed in the "cumulative" column of FIG. 5 .

That is, the “cumulative total” in FIG. 5 or FIG. 6 represents the accumulated purchase request quantity for each purchase request price that is applied for purchase above the respective purchase request price.

For each purchase request price, the accumulated accumulated purchase request quantity applied for purchase above the purchase request price corresponds to a section larger than the lower limit quantity of the purchase request quantity section condition (where the successful bid price can be determined based on the purchase request price) As the successful bid price is determined as the (specific among the prices) below the lowest purchase request price among the purchase request prices,

The purchaser (at least one of the buyers) who applied for a purchase at the purchase request price higher than the successful bid price is determined as the purchaser who concluded the purchase, and the purchaser who concluded the purchase can purchase at the same price as the successful bid price, and the purchase application price less than the successful bid price Buyers (at least one of the buyers) who applied for purchase as The results of the transaction including those determined as the unsuccessful purchaser are derived, and the purchase application terminal (or sales application terminal: SS ?) Step (or means) to be provided or notified to the connected terminal including

- This step (or means) is a step (or means) in which the successful bid price is determined according to the end of the group purchase application deadline and the results of the transaction are derived, including the division into the purchaser who has concluded a purchase and the purchaser who has not entered into a purchase agreement.

(Therefore, unlike the conventional group purchase method, even though there are purchasers who have concluded purchases even though they are group purchases, there may be buyers who have not concluded purchases. )

The description of this step (or means) has been described in detail with the example of FIG. 5 above, so it will not be described in detail.

Of course, at the discretion of the site operator or the seller or a separate remedy, some or all of the purchasers who have not entered into a purchase agreement are recognized or relieved as the purchasers who have concluded a purchase. Alternatively, the entire purchase may be concluded or part of the cost support may be provided.

A step (or means) that will be explained later, if the purchase cost (mainly reflecting the desired purchase price) paid in advance by the buyer at the time of the purchase application is greater than the purchase cost reflecting the successful bid price, the step (or means) of refunding the difference In , after the refund amount is calculated, it is in the same context as it was said that more than the refund amount calculated at the discretion of the site operator or the seller may be refunded.

After the winning bid price is determined,

Through the group purchase server,

The pre-paid purchase cost (or more) accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to purchase is refunded (taking into account the variable cost);

The stage in which the difference cost (or more) pre-paid in excess of the purchase cost in which the successful bid price is reflected among the pre-paid purchase costs accepted from the purchase application terminal used by the buyer who is determined to be a purchaser is refunded (considering variable costs) (or means); Step 4-1 (or means)

- In this step (or means), the group purchase server 16 refunds all the purchase costs (or more) paid in advance by the purchaser who is not determined as the purchaser who concluded the purchase after the end of the group purchase (taking into account the variable cost), This is a step (or means) of refunding (considering variable costs) the pre-paid cost (or more) in excess of the purchase cost in which the successful bid price is reflected among the purchase costs paid in advance by the contracted buyer.

That is, the final selling price is determined by the successful bid price, and the purchaser initially calculates the purchase cost reflecting his/her purchase request price, subtracts the purchase cost reflecting the successful bid price from the amount paid in advance, and refunds the rest.

Although unlikely, someone may, at their discretion, reimburse you more than the 'remaining' amount above. That is why they said that they would refund 'more than' the difference in cost. In addition, the word 'over' in the reimbursement of other expenses in other parts of the present application is also a word used for the same purpose.

And, since the present invention does not apply for a patent on a method of refunding a part of the amount paid by card, that is, it is not a patent application for electronic payment among patents related to electronic commerce, so the problem to be solved in the present invention is not thought to be, but

Speaking of refunding the amount paid in advance by card,

In other words, let's mention a few things about how to refund the amount (or more) by subtracting the purchase cost with the successful bid price from the prepaid amount to the buyer who paid in advance for the amount exceeding the purchase cost with the successful bid price reflected with the card (Other methods may be possible.)

1. Automate the cancellation of pre-payment (card) and payment of the purchase cost with the newly successful bid price reflected.

2. Charge the amount paid in advance on the card bill as a positive amount, and charge the difference (= the amount equal to the amount paid in advance minus the purchase cost reflecting the successful bid price) as a negative amount, resulting in the successful bid price Arranged by paying the reflected purchase cost.

3. The card company remits the different fees to the customer's account

4. Remit the amount by subtracting the purchase cost reflecting the successful bid price from the amount the seller paid in advance to the customer's bankbook (the seller takes the card fee loss)

5. Accumulate points or cyber money to the credit card company for an amount equal to the amount paid in advance minus the purchase cost with the successful bid price reflected (it can be turned into cash at any time)

6. Accumulate points or cyber money on the operating site by subtracting the purchase cost with the successful bid price from the amount paid in advance (it can be turned into cash at any time)

In addition, the following steps (or means) may be further added to the group purchase method according to the present invention.

After the winning bid price is determined,

Through the group purchase server,

The pre-paid purchase cost (or more) accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to purchase is refunded (taking into account the variable cost);

The additional settlement price for the purchase cost that is insufficient compared to the purchase cost in which the successful bid price is reflected in the pre-paid purchase cost accepted from the purchase application terminal used by the purchaser determined as the purchaser who has been determined to be the purchaser Step (or means) accepted from the requesting terminal;

-This step (or means) means that when the amount paid in advance by the buyer before the successful bid price is determined is less than the purchase cost with the successful bid price reflected, the buyer pays more for the shortfall. Detailed explanation of this step (or means) will be omitted.

If the cancellation of purchase from the purchase application terminal used by any of the purchasers who applied for purchase through the group purchase server is accepted after being determined as the purchaser, the purchase request accepted from the purchase application terminal used by the purchaser whose purchase application is cancelled. Step 4-2 (or means) in which some or all of the purchase cost paid in advance is refunded as a purchase cancellation penalty (taking into account variable costs) and the remaining balance (or more) is refunded (taking into account variable costs)

- In this step (or means), part or all of the purchase cost paid by the buyer in advance will be paid as a penalty in the event that the purchase application is canceled after being determined as the purchaser who has concluded the purchase among the purchasers who have applied for purchase, which may cause damage to the seller. It is a step (or means) to compensate the loss of the seller and to guarantee the reliability of the transaction by recovering it (taking variable costs into account) and providing it to the seller.

In other words, from the seller's point of view, all buyers who applied for purchase sold the product by applying for sale by lowering the selling price as much as possible through the calculation of separate multi-storey profit under the judgment that all buyers who applied for purchase would purchase if they were determined to be purchasers who concluded purchases. If it is canceled, even if the product is sold after a successful bid, profits may be significantly reduced or damage may occur rather than initially thought, so a certain penalty is given to the buyer who cancels the purchase application.

Furthermore, the group purchasing method according to the present invention may further include the following steps (or means).

Step 1-1 in which the payment for the sales deposit is accepted in advance (considering the variable cost) before the successful bid price including the time when the sales information is transmitted (from the sales application terminal) through the group purchase server is determined ( or means).

- In this step (or means), the sales deposit is paid in advance from the seller in order to compensate for the loss of the purchasers who have concluded the purchase, which may occur when the sale is canceled or the product is not provided smoothly even though the purchaser has been derived. This is to provide some or all of the sales deposit paid in advance (in consideration of variable costs) to the purchasers who have received it (mainly at the time of application for sale) and if the seller does not fulfill his/her obligations in the future, the reliability of the transaction is to secure

After the purchaser has been identified,

The seller accepts the cancellation of sale from the sale application terminal used by the seller through the group purchase server, or the seller assumes the obligations under the sales right granted to the seller. fulfill If information is accepted, the sales deposit paid in advance (considering variable costs) is refunded or

Step (or means) of refunding the sales deposit (or more) to the seller (taking into account variable costs) when a normal transaction is made

- As described above, in this step (or means), if the seller cancels the sale without a justifiable reason or does not perform the product provision smoothly, the seller recovers the bid deposit paid in advance in order to compensate for the loss of the purchasers. step (or means).

If a normal transaction is made, the sales deposit will be refunded to the seller.

In addition, the following two steps (or means) may be further added.

After the successful bid price is determined through the group purchase server,

The payment for the total purchase cost (considering the variable cost) is accepted from the purchase application terminal used by the new buyer or the buyer who has not been able to enter into a purchase agreement.

The purchase cost reflected in the successful bid price is the pre-paid purchase cost accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to conclude a purchase due to a purchase application at a purchase request price less than the above-mentioned successful bid price. Including that payment for insufficient purchase costs is accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to conclude a purchase (taking into account variable costs)

When the total purchase cost (considering variable costs) is paid accept it ,

This is to enable the acquisition of sufficient information on the prediction of the appropriate successful bid selling price, and thus, among the buyers who were sure to purchase if the price is in the appropriate price range, the buyer who fails to purchase as a result of applying for a purchase at too low a purchase request price due to insufficient information minimize the number

Up to now, facts have been described as concepts that may belong to embodiments of the concepts claimed in the present application in order to facilitate understanding of the generic concepts of the present application.

Hereinafter, the generic concept of the present application will be described.

The group purchase disclosure information to which the comprehensive concept of the present application is applied contains the content that more benefits are given to the buyer as the number of purchase requests increases. These benefits include none at all. This is because the benefit may not be given if the quantity requested for purchase is less than a certain amount.

So far, the method of the present application has been described with only the benefit of lowering the price among the benefits. That is, as shown in Fig. 4, Fig. 5 or Fig. 6, as the quantity of purchase requests increases, the price is lowered as shown in Fig.

From the buyer's point of view, the benefit is not just a lower price.

In addition to lowering the price as the number of purchase requests increases,

As the number of purchase requests increases, various products (= goods or services) in addition to the basic product are added to the buyer (including changes to more valuable products), and the supply condition is also a benefit from the buyer's point of view.

Even if the number of purchase requests increases, the price remains the same, but as the number of purchase requests increases, more various products (= goods or services) are added to the buyer (including those that are changed into more valuable products) and supplied. Conditions also correspond to benefits from the buyer's point of view. The case where the price remains the same includes the case where it is free.

As described above, while the price remains the same (or even slightly lowered), when more products are added to the buyer (including changing to a more valuable product), from the buyer's point of view, more products of a certain value are added (as a more valuable product). change), and from the seller's point of view, the buyer only needs to spend a small amount more than when any value received by the buyer is converted into an amount.

For example, it is often more profitable for the seller to keep the price of 10,000 won and give an additional 4,000 won than to sell meat at 4,000 won at a discount of 4,000 won for meat that is normally priced at 10,000 won. Because the cost of the additionally supplied 4,000 won worth of meat may be only 1,000 won, from the seller's point of view, it is 3,000 won more profitable than selling at a 4,000 won discount. Nevertheless, there will be many cases where the buyer is also satisfied.

As the number of purchase requests increases, other products are added (including those that are changed to more valuable products) in addition to the basic product, and the types of products supplied to the buyer are very diverse. It is up to the seller to decide. For example, the following products may be additionally given.

Gift certificates (eg 10,000 won, 50,000 won, 100,000 won), cash refunds (eg 10,000 won, 50,000 won, 100,000 won), service time (eg 10 minutes, 30 minutes, 1 hour), service period (eg 1) Month, 6 months, 1 year), discount rate (ex. 10%, 30%, 50%), exemption of certain amount (ex: 10,000 won out of 30,000 subscription fee, 20,000 won out of 30,000 subscription fee, 3 out of 30,000 subscription fee) 10,000 won exemption), products (eg cell phone rings, stylus pens, liquid crystal protection film), products (eg drinks, tea, wine), etc.

If the additional product supplied is "cash refund", it means that the seller can give the buyer cash.

4 and 5 are charts showing the results of joint purchase announcement and purchase application in which the price decreases as the number of purchase requests increases with respect to a stake A whose usual price is 10,000 won.

However, as shown in Figure 10, depending on the seller, the price does not change even when the quantity of purchase requests increases, and as the quantity of purchase requests increases, a certain product is added (or changed to a more valuable product) to the buyer and supplied. (In order to reduce the number of drawings, the information and results of the group purchase were expressed at once.)

10 will be described as follows.

Even if the number of purchase requests increases, the price remains the same at 10,000 won. However, as the number of purchase requests increases,

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), drinks and tea are additionally supplied,

In section 4 (purchase request quantity), it can be seen that beverages, tea and wine are additionally provided.

(if not,

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), only tea is additionally supplied,

In section 4 (purchase application quantity), it can be said that only wine is additionally supplied. There will be no confusion as long as the group purchase announcement is made on how to interpret the additional supply products for each purchase application quantity section in the table showing the group purchase disclosure information as shown in FIG. 10 .

In this application, in the table where additional supply products are displayed,

When there is no overlapping benefit in the purchase application benefit column corresponding to each purchase quantity section as shown in Figure 10,

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), drinks and tea are additionally supplied,

In section 4 (purchase application quantity), the method of interpreting that beverages, tea and wine are additionally supplied will be referred to as the 'accumulated benefit application method' in the additional benefit application method,

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), only tea is additionally supplied,

In section 4 (purchase application quantity), the method of interpreting that only wine is additionally supplied will be referred to as 'individual benefit application method' in the additional benefit application method.

As shown in FIG. 11, if the benefits of additional supply products are duplicated in the purchase application benefit column corresponding to each purchase quantity section, there will be no confusion even without notice of the interpretation of the table.

(The overlapping benefit of adding drinks is marked in sections 2 and 3 in Figure 11, and the overlapping benefit of adding drinks and tea is marked in sections 3 and 4)

11, it will be easy to interpret as follows, unless there is a specific condition.

In section 2 (purchase application quantity), only beverages are additionally supplied,

In section 3 (purchase application quantity), only drinks and tea are additionally supplied,

In section 4 (purchase request quantity), drinks, tea and wine are additionally supplied)

Here, the description will be continued under the assumption that it is mainly announced that additional supply products will be configured as shown in FIG. 11 when the group purchase announcement is made as shown in FIG. 10 .

Looking at the result part of FIG. 10, it can be seen that the total number of purchase requests was 490, and the purchase application benefits corresponding to section 3 were successful bids by the same principle as the explanation principle related to FIG. In other words, if the price of the successful bid is 10,000 won and the information on the group purchase notice that the additional benefit application method is applied as the “accumulated benefit application method”, the additionally supplied products will be beverages and tea (depending on the seller). However, if it is notified in the group purchase disclosure information that the additional benefit application method is to be applied as an “individual benefit application method”, the rule of additionally supplying only tea may be applied).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section when applying for purchase purchases under the condition of the benefit corresponding to the 3rd (purchase application quantity) section The purchase is not concluded by the purchaser who applied for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 .

However, to explain it in a little more detail,

Looking at the result part of Fig. 10, the total number of purchase requests was 490,

Looking at the purchase application status, once it was announced in the group purchase disclosure information that the additional benefit application method was applied as the “accumulated benefit application method”,

The number of purchase requests that selected the purchase application benefit without additional products for 10,000 won is 40, the total is 40,

The number of purchase requests for which the purchase application benefit is an additional product for 10,000 won is 130, the total is 170,

The number of purchase requests that selected the purchase application benefit, in which beverages and tea are additional products at 10,000 won, was 180, and the total was 350.

The number of purchase requests that selected the purchase application benefit, in which beverages, tea and wine are additional products for 10,000 won, is 140, and the total is 490.

(If it is notified in the group purchase disclosure information that the additional benefit application method is applied as an “individual benefit application method”,

The number of purchase requests that selected the purchase application benefit without additional products for 10,000 won is 40, the total is 40,

The number of purchase requests for which the purchase application benefit is an additional product for 10,000 won is 130, the total is 170,

The number of purchase requests that selected the purchase application benefit, in which the car is an additional product at 10,000 won, is 180, and the total is 350.

The number of purchase requests that select the purchase application benefit of wine as an additional product at 10,000 won is 140, and the total is 490.)

Since the lower limit of the condition of the purchase request quantity section in sections 1, 2, and 3 is smaller than the accumulated purchase request quantity, the “satisfaction or not” column in sections 1, 2, and 3 is “satisfied”. The purchase application benefit of section 3, which is the best purchase application benefit among the purchase application benefits corresponding to the purchase application quantity section where the “satisfaction” column is “satisfied,” is 10,000 won, and the method of applying additional benefits is “How to apply the cumulative benefits” If it is notified in the group purchase disclosure information that it is applied as “ The cumulative purchase request quantity of 350 purchased by the contracted buyer is 10,000 won, and beverages and tea are additionally supplied to the contracted buyer.

(If it is notified in the group purchase disclosure information that the additional benefit application method is applied as an “individual benefit application method” depending on the seller, the additionally supplied product will be only a car.)

Since the lower limit (500 pieces) of the condition of the purchase request quantity section of section 4 is larger than the accumulated purchase request quantity (490 pieces), the “satisfaction” column of section 4 is “dissatisfied”, so section 4 The product cannot be supplied with the purchase application benefit that is 10,000 won but additionally drinks, tea, and wine are supplied. So, if a purchase application is made by selecting an additionally supplied product while paying 10,000 won in advance at the time of purchase application, the purchaser who has not been able to conclude a purchase due to the selection of the purchase application benefit of the condition in section 4 will receive 10,000 each. You will be refunded one by one.

Since the process of reaching the above conclusion has been dealt with in detail in the description of FIG. 5 , further detailed description will be omitted.

For reference, FIG. 5 may be represented as FIG. 22, and the meanings of FIGS. 5 and 22 are the same.

12 exemplifies selling an oven.

12 shows that even as the quantity of purchase requests increases as shown in FIG. 10, the price does not change at 500,000 won, and as the quantity of purchase requests increases, more products to be supplied are added (including changes to more valuable products). .

Looking at the result part of Figure 12, the total number of purchase requests was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been successfully bid by the same principle as in FIG. 5 or FIG. 10 . In other words, the benefit of the successful bid is that the price is 500,000 won,

If it was announced in the group purchase disclosure information that the additional benefit application method is to be applied as a “cumulative benefit application method”, the additionally supplied products will be scales and frying pans. If it is announced in the group purchase disclosure information that it is applied as

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section at the time of the purchase application purchase application benefit conditions corresponding to the 3rd (purchase application quantity) section The purchase is concluded with the purchase order, and the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not concluded. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 or FIG. 10 .

Now, let's look at an example in which more products are added (including changing to more valuable products) as the number of purchase requests increases while the price is free.

This is mainly an example that can be used for service contracts, such as Internet subscriptions and insurance products. When subscribing to such a service, there is no fee at the time of subscription, but it can be applied to products that require a fixed fee at regular intervals (eg, every month).

I will explain the Internet subscription product as an example.

Among the products of an internet network supplier called KT, there is a high-speed internet product that requires a monthly payment of 30,000 won. However, if you sign up with a contract to continue using it for more than 3 years, you only need to pay 25,000 won per month. From the buyer's point of view, in most cases, no money is required for the name of the subscription fee. (The group purchase may be announced to pay the fee for the first month in advance, but in this example, it will be explained as not doing so.)

13 is an example showing the announcement and results of group purchase for KT, high-speed Internet, monthly 25,000 won, 3-year contract product subscription.

As shown in Figure 10, the price does not change (to 0 won (= free)) even when the number of purchase requests increases, and as the number of purchase requests increases, more products are added (including changes to more valuable products) .

13, the total number of purchase requests was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been successfully bid by the same principle as in FIG. 5 or FIG. 10 . In other words, if the price of the successful bid benefit is 0 won (= free), and it is announced in the group purchase disclosure information that the additional benefit application method is applied as the “accumulated benefit application method”, the additional products supplied will be a mouse and MP3 player. (Depending on the seller, if the group purchase announcement information indicates that the additional benefit application method is applied as an “individual benefit application method”, the rule of additionally supplying only MP3 may be applied). At the same time, the purchaser who has concluded a purchase has to pay 25,000 won per month.

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section when applying for purchase purchases under the condition of the benefit corresponding to the 3rd (purchase application quantity) section The purchase is not concluded by the purchaser who applied for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 or FIG. 10 .

Also, let's see if the benefit is cash.

When a seller offers a cash benefit to a buyer, it means that the seller gives cash to the buyer.

19 is an example showing the announcement and results of group purchase for KT, high-speed Internet, 25,000 won per month, 3 year contract product subscription.

As shown in Figure 10, the price does not change (to 0 won (= free)) even when the number of purchase requests increases, and as the number of purchase requests increases, more products are added (including changes to more valuable products) .

19, the total number of purchase requests was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been successfully bid by the same principle as in FIG. 5 or FIG. 10 . In other words, if the price of the successful bid benefit is 0 won (= free), and it is announced in the group purchase disclosure information that the additional benefit application method is applied as the "accumulated benefit application method", an additional cash of 60,000 won (= 10,000 won + 2) 10,000 won + 30,000 won) will be deposited to the buyer. may be). At the same time, the purchaser who has concluded a purchase has to pay 25,000 won per month.

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section at the time of the purchase application purchase application benefit conditions corresponding to the 3rd (purchase application quantity) section The purchase is concluded with the purchase order, and the purchaser who applied for purchase while selecting the benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not concluded. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 or FIG. 10 .

Also, let's look at the case where the unit of purchase request quantity is the amount.

For example, as shown in FIG. 14 , a group purchase is being promoted for several breads of a specific type in a certain bakery.

When purchasing several types (or one type or all types) bread subject to group purchase at the price at the time the buyer visits and purchases it, the number of purchase requests applied for group purchase (= As the purchase request amount) increases, the discount rate may correspond to the price at the time the buyer visits and purchases. )

In this case, when the buyer applies for purchase, he or she can apply for purchase while expressing his/her intention to purchase a certain amount of bread.

In that way, looking at the results of purchase requests (of a number of buyers) in FIG. 14,

Since the unit of the purchase request quantity is 10,000 won, the total purchase request quantity is 4.9 million won, and it can be seen that the purchase application benefit corresponding to the 3rd section was successful bid by the same principle as in FIG. 5 or 10 . In other words, if the successful bid benefit is notified in the group purchase disclosure information that the additional benefit application method is to be applied as a “cumulative benefit application method,” will be able to purchase at a 45% (=0%+15%+30%) discount. , a rule that allows you to purchase only with a 30% discount may apply).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section at the time of the purchase application purchase application benefit conditions corresponding to the 3rd (purchase application quantity) section The purchase is concluded with the purchase order, and the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not concluded. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 or FIG. 10 .

It is a condition that each purchaser who has concluded a purchase can actually purchase the amount of bread as much as the amount requested for purchase at the discounted percentage price corresponding to the winning bid benefit.

Refund may not occur even if you pay in advance for the amount requested for purchase based on the price at the time the group purchase is announced before the winning bid benefit is decided.

After the winning bid benefit is determined, if the buyer visits and purchases based on the price at the time of purchase, payment may not be made in advance, so a refund may not occur.

This method may be more suitable for products with short price fluctuations and low margins. For example, automobile gasoline.

Fig. 15 will be described as an example.

As in FIG. 14 , the unit of purchase application quantity in FIG. 15 is also the amount.

For example, as shown in FIG. 15 , a group purchase is attempted for several oils of a specific type at a certain gas station.

When purchasing several types (or one type or all types) subject to group purchase at the price at the time the buyer visits and purchases oil, the number of purchase requests applied for group purchase (= As the purchase request amount) increases, the discount rate may correspond to the price at the time the buyer visits and purchases. )

In this case, when the purchaser applies for purchase, he or she can apply for purchase while expressing his/her intention to purchase some amount of oil.

In that way, looking at the results of the purchase application (of a number of buyers) in Fig. 15,

Since the unit of the purchase request quantity is 10,000 won, the total purchase request quantity is 4.9 million won, and it can be seen that the purchase application benefit corresponding to the 3rd section was successful bid by the same principle as in FIG. 5 or 10 .

In other words, if the group purchase announcement information indicates that the additional benefit application method is to be applied as a “cumulative benefit application method” for the successful bid, each purchaser who has passed the purchase application will purchase the amount of gasoline equivalent to the amount they expressed their intention to purchase while applying for purchase. will be able to purchase at a 3% (=0%+1%+2%) discount. , a rule that allows you to purchase with a 2% discount may apply).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section at the time of the purchase application purchase application benefit conditions corresponding to the 3rd (purchase application quantity) section The purchase is concluded with the purchase order, and the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not concluded. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 or FIG. 10 .

It is a condition that each purchaser who has concluded a purchase can actually purchase the amount of oil he or she has applied for at the discounted percentage that corresponds to the winning bid benefit.

Refund may not occur even if you pay in advance for the amount requested for purchase based on the price at the time the group purchase is announced before the winning bid benefit is decided.

After the winning bid benefit is determined, if the buyer visits and purchases based on the price at the time of purchase, payment may not be made in advance, so a refund may not occur.

In the case of gasoline, the unit of quantity requested for purchase may be liters.

Fig. 16 will be described as an example.

Since the unit of the purchase request quantity is liter, the total purchase request quantity is 490 liters, and it can be seen that the purchase application benefit corresponding to the 3rd section has been successfully bid by the same principle as in FIG. 5 or FIG. 10 . In other words, the successful bid is the volume (unit: unit: liters) of gasoline at a 3% (=0%+1%+2%) discount. If it has been notified in the public information, the rule of purchasing at a 2% discount may be applied).

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section at the time of the purchase application purchase application benefit conditions corresponding to the 3rd (purchase application quantity) section The purchase is concluded with the purchase order, and the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not concluded. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 or FIG. 10 .

It is a condition that each purchaser who has concluded a purchase can actually purchase the amount of gasoline as much as the volume requested for purchase at the discounted percentage price per liter corresponding to the successful bid benefit.

If the payment is made in advance before the winning bid benefit is determined, the amount obtained by multiplying the discounted percent price per liter for purchase by the requested volume multiplied by the discounted percent price per liter corresponding to the winning bid benefit multiplied by the requested volume The difference, minus the cost, will be refunded.

In the case of pre-payment of the amount requested for purchase based on the price at the time of public announcement of the group purchase before the winning bid benefit is determined, the discount equivalent to the successful bid benefit per liter at the discounted percentage of the price per liter applied for purchase The difference will be refunded minus the price per liter of the percentage paid (refer to the refund section in Fig. 16 - Assume that the price per liter without discount is 100 won),

After the winning bid benefit is determined, if the buyer visits and purchases based on the price at the time of purchase, payment may not be made in advance, so a refund may not occur (not shown).

Now, let's look at an example where an additional benefit includes an extended benefit.

When promoting a group purchase of 6 months aerobics class product, there may be a group purchase announcement and result as shown in FIG. 17 .

Referring to the result part of FIG. 17, it can be seen that the total number of purchase requests was 490, and the purchase application benefit corresponding to section 3 was successful bid by the same principle as in FIG. 5 or FIG. That is, if the price of the successful bid benefit is 300,000 won and the information on the group purchase notice that the additional benefit application method is applied as the “accumulated benefit application method”, the additionally supplied products will be one-month extension and two-month extension, total It will be extended by 3 months. In other words, as the basic 6-month course is extended by 3 months (= none+1 month+2 months), the course can be taken for a total of 9 months. If it is notified in the group purchase disclosure information that it is applied as

And so far, as the number of purchase requests increases,

There are no additional products, only the price is lowered or

Although the price does not change, only added products are accumulated or only benefits that are changed to more valuable products are given as examples.

As the price decreases as shown in FIG. 18, additional products may be accumulated or there may be a benefit of being replaced with more valuable products.

18 is an example of the announcement of group purchase for mobile phone subscription products and the results.

It is assumed that the product is a product in which a contract is made to use a service for two years, which is required to pay 50,000 won per month as a basic fee, while purchasing a specific mobile phone, moving a mobile phone service company to a specific carrier.

In section 1 of the purchase request quantity section, as a mobile phone is purchased (an old phone is free, but it is a newer phone), 300,000 won must be paid for the mobile phone. If there is, the price of the specific mobile phone above is 700,000 won.)

When changing from section 1 to section 2, the price of the mobile phone does not change, but an additional mobile phone ring worth 10,000 won is supplied.

When changing from section 2 to section 3, the mobile phone price is also lowered by 10,000 won, and additional products are added (or changed) from a mobile phone ring worth 10,000 won to a stylus pen worth 20,000 won.

When changing from section 3 to section 4, the mobile phone price is lowered by 10,000 won, but there are no additional products.

18, the total number of purchase requests was 490,

It can be seen that the purchase application benefit corresponding to section 3 has been successfully bid by the same principle as in FIG. 5 or FIG. 10 . In other words, if the successful bid is for a mobile phone price of 290,000 won, and it is announced in the group purchase disclosure information that the additional benefit application method is to be applied as a “cumulative benefit application method,” the additionally supplied product will be a mobile phone ring worth 10,000 won and 2 It is a stylus pen worth KRW 10,000. (Depending on the seller, if the group purchase announcement information indicates that the additional benefit application method is applied as an “individual benefit application method”, the mobile phone price is 290,000 KRW, and only the stylus pen worth 20,000 KRW is added. supply rules may apply). And, the purchaser who concluded the purchase is subscribed to the service using the rate plan with a basic fee of 50,000 won per month for 2 years.

Now, let's look at the complexity of added or changed benefits as the number of purchase requests increases. Although various benefits including cash, gift certificates, discount rates, or general industrial products are added or changed, in the following example, as the number of purchase requests increases, more cash and general industrial products are added (changed to more valuable products). also included) will be described in the embodiment.

20 is an example showing the announcement and results of group purchase for KT, high-speed Internet, 25,000 won per month, 3 year contract product subscription.

As shown in FIG. 10, even if the purchase request quantity increases, the price does not change to 0 won (= free), and as the purchase application quantity increases, more products are added (including changes to more valuable products).

Looking at the result part of Figure 20, the total number of purchase requests was 490,

It can be seen that the benefit corresponding to section 3 has been successfully bid by the same principle as in FIG. 5 or FIG. 10 . That is, if the price of the successful bid benefit is 0 won (= free), and it is announced in the group purchase disclosure information that the additional benefit application method is applied as the “accumulated benefit application method”, an additional cash of KRW 60,000 (= KRW 10,000 + 2) 10,000 won + 30,000 won), a mouse worth 10,000 won, and an MP3 worth 50,000 won will be supplied to the buyer. , the rule of additionally supplying only 30,000 won in cash and MP3 (equivalent to 50,000 won) may be applied). At the same time, the purchaser who has concluded a purchase has to pay 25,000 won per month.

In addition, the purchaser who applied for purchase while selecting the purchase application benefit corresponding to the 1st, 2nd, or 3rd (purchase application quantity) section at the time of the purchase application purchase application benefit conditions corresponding to the 3rd (purchase application quantity) section The purchase is concluded with the purchase order, and the purchaser who applies for purchase while selecting the purchase application benefit corresponding to section 4 (purchase application quantity) at the time of purchase application is not concluded. This purchase execution principle has been dealt with in detail in the description related to FIG. 5 or FIG. 10 .

10 to 21 as an example, in order to make it easier to understand the explanation of the benefits, the elements of the benefits are divided into the purchase application price (or discount rate) and additional supply products. The purchase request price is the amount that can be enforced for the buyer to pay the buyer's request for purchase as a condition for the seller's obligation to perform after the purchase is concluded. just let it go The discount rate may be the discount rate for the amount that the buyer must deposit when applying for purchase, or it may be the amount that the buyer can receive a discount on when receiving the actual product. It may be efficient, or it may be more efficient if it is written in the field where the seller must perform.

In any case, the factors regarding benefits,

In a state where the content of benefits, including expressing clearly what the buyer has to do and what the seller has to do, can be clearly understood by the buyer,

It can be written all at once in the same column, or it can be arbitrarily divided by the indicator. In dividing the display, it may be divided into two or more elements, including the purchase application price (or discount rate) and the additional supply product, divided into two elements.

Now, let's summarize what we want to comprehensively pursue in this paper.

Detailed description of each step (or means) below will be omitted. This is because, in a transaction in which only the price is lowered as the quantity of purchase requests increases, the key points of the following techniques have been described in great detail, especially in the description of FIG. 5 . This is because the difference is not important and can be understood by analogy enough from the previous explanation.

And, including the process of pre-payment and refund of the purchase cost, the process of paying and refunding the purchase deposit, and the process of paying and refunding the sales deposit

In a transaction where only the price can be lowered as the quantity of purchase requests increases, the techniques described above, but not described below, can be applied as they are. Since it has been described in detail in the description related to FIG. 5, the application method will not be separately described.

In the description of the content of the claim below, "purchase application price" in the description of how to receive the benefit of lowering only the price as the number of purchase applications increases is replaced with the word "purchase application benefit", and "purchase more than The meaning of "application price" is replaced with the meaning of "benefits from the purchase application below", and the meaning of "purchase application price less than" has been replaced with the meaning of "benefits from the purchase application exceeding". This is because the purchase request price and the purchase application benefit are inversely proportional to each other. For example, when the purchase request price increases, the purchase application benefit decreases, and when the purchase application price decreases, the purchase application benefit increases.

Even if you do not need to explain the other changes, you can easily find out by referring to the explanation of how you can receive the benefit of lowering only the price as the number of purchase requests increases.

A group purchase server and a purchase application terminal that can be used by one or more purchasers can be connected to each other through a network communication network including the Internet. e-commerce system (or a group purchase server and one or more Purchase request group In the group purchase method using an electronic commerce system in which a terminal and a sales application terminal that can be used by a seller can be mutually connected through a network communication network including the Internet),

The group purchasing method according to the present invention consists of the following steps (or means).

(Step (or means) of transmitting group purchase announcement information including that the purchase application benefit is matched for each of two or more purchase application quantity sections for the transaction target product to the group purchase server;)

- In this step (or means), as shown in Fig. 10, the seller provides the site operator with a group purchase condition including that different purchase application benefits are matched for each of two or more different purchase application quantity sections for a specific product. It is a step (or means) entered by the operator or directly entered by the seller.

It is self-evident that different purchase application prices are considered to correspond even if different purchase application prices do not correspond to different purchase application quantity sections in the group purchase announcement, and a specific discount rate compared to different normal prices is corresponding. belong to the scope of the right. This is because, when a discount rate is applied to the normal price, a discounted price is derived.

In principle, a benefit should have two or more conditions that are comparable to each other.

In addition, a narrower range of steps can be created as follows by adding a limited phrase to this step , 'so that there is a section in which the price does not change even if the purchase request quantity section is changed or there is a section in which the price change is extremely insignificant.

(Even if the purchase request quantity section is changed, there is a section in which the price does not change or the price change is extremely insignificant.

Group purchase announcement information including that the purchase application benefit is matched for each of two or more purchase application quantity sections for the transaction target product is sent to the group purchase server sent is a step (or means);)

The transformation step corresponds to each purchase application quantity section as shown in Fig. 10, Fig. 11, Fig. 12, Fig. 18, Fig. 19, or Fig. It is a step (or means) to ensure that there is no change in price or a section in which the price change is very insignificant even if the purchase request quantity section changes among the contents of the purchase application benefit conditions. As only the additional product is changed according to the change, the price may not be a factor in choosing which purchase application benefit to choose from the buyer's point of view.

A paid product is also useful, but it will be more useful for products that are free from the start, such as insurance, internet subscription, and mobile phone subscription products, and only require a contract, and can be more profitable for sellers in terms of margin. .

The following steps (or means) are described as applicable to all cases, regardless of whether there is a change in the price. Please refer to the steps described below for the subsequent steps (or means) in the state in which the purchase application benefits are matched for each purchase request quantity section.

Through the group purchase server, the group purchase announcement information including that the purchase application benefit is matched for each of two or more purchase application quantity sections for the product to be traded is transmitted to the purchase application terminal (or sales application terminal: SS ?) to the connected terminal including accepted step (or means);

- In this step (or means), as shown in FIG. 10 (~ 20), the seller sets the group purchase condition including that different purchase application benefits are matched for each of two or more different purchase application quantity sections for a specific product. It is a step (or means) of providing the information to the operator so that the group purchase announcement information entered by the site operator or directly input by the seller can be displayed on the purchase application terminal.

When a specific discount rate is applied to two or more purchase application quantity sections, it is recommended that different discount rates be used for each purchase request quantity section.

And, the specific discount rate may be 0%. That is, there may be a purchase request quantity section to which the normal price is applied.

In addition, a more specific step (or means) can be created as follows by adding a limited phrase to this step , 'so that there is a section in which the price does not change even if the purchase request quantity section is changed or there is a section in which the price change is very insignificant. .

Even if the purchase request quantity section is changed, the price no change or So that there is a section where price fluctuations are very insignificant,

Through the group purchase server, the group purchase announcement information including that the purchase application benefit is matched for each of two or more purchase application quantity sections for the product to be traded is transmitted to the purchase application terminal (or sales application terminal: SS ?) to the connected terminal including receive the step (or means) of being introduced;

The transformation step corresponds to each purchase application quantity section as shown in Fig. 10, Fig. 11, Fig. 12, Fig. 18, Fig. 19, or Fig. It is a step (or means) to ensure that there is no change in price or a section in which the price change is very insignificant even if the purchase request quantity section changes among the contents of the purchase application benefit conditions. As only the additional product is changed according to the change, the price may not be a factor in choosing which purchase application benefit to choose from the buyer's point of view.

A paid product is also useful, but it will be more useful for products that are free from the start, such as insurance, internet subscription, and mobile phone subscription products, and only require a contract, and can be more profitable for sellers in terms of margin. .

From the seller's point of view, it is often more profitable to supply the buyer with an additional product (or even more) at the price he was trying to lower than to lower the price. This is because the cost of the additionally supplied product is below the price of the additionally supplied product anyway. If the additionally supplied product is a product that was originally handled by the seller who requested the group purchase, the cost will be lower,

Even if the additionally supplied product was not handled by the seller who requested the group purchase, the cost of procurement by the seller will be lower since it is a bulk purchase anyway.

The following steps (or means) are described as applicable to all cases, regardless of whether there is a change in the price. Please refer to the steps described below for the subsequent steps (or means) in the state in which the purchase application benefits are matched for each purchase request quantity section.

Either one of the two or more purchase application benefits is selected and input from the purchase application terminal used by each purchaser, or purchase application information including the purchase application quantity is input and transmitted to the group purchase server (It has been stored in the group purchase server: SS ?) becoming (or means);

- In this step (or means), after connecting to the group purchase server 16 through the purchase application terminal 12 used by each purchaser, the group purchase announcement information on the products for sale provided by the group purchase server 16 is displayed. If you want to purchase through group purchase by selecting a specific product, select a purchase application benefit that includes the desired purchase application price within the available time for purchase, and enter purchase application information for the purchase application quantity, The purchase application information may be transmitted to and stored in the group purchase server 16 .

At this time, each purchaser may directly input the desired purchase application benefits, and a plurality of purchase application benefits provided by the group purchase server 16 as in the description given for the example through FIG. You can also select and input any one of them.

There are various input methods for selection, including inputting the provided purchase application benefit text individually or clicking a button related to the provided purchase application benefit text.

Selecting and inputting any one has been described in detail with reference to FIG. 4 or FIG. 5 above, so I will end the description here with this.

In addition, if the quantity of the purchase application is one, the quantity of the purchase application may be automatically processed as one without separately inputting the quantity of the purchase application. That is, for a specific purchase application quantity including a case where the purchase application quantity is 1, the purchase application quantity may be automatically entered and processed without separately inputting the purchase application quantity.

In addition, each buyer may operate so that he/she can change the purchase application benefits that he/she has applied for until the successful bid benefits are determined. As an example of the method of change, it is possible to change only by selecting the new purchase application benefit, or to cancel the previous purchase application and apply for a new purchase with the new purchase application benefit. If payment is made in advance at the time of purchase application, additional payment or refund may be made according to the changed price settlement rules.

In the case where the purchase application price is paid among the selected purchase application benefit conditions,

Part of the purchase cost in which the purchase application price is reflected before the successful bid benefit is determined, including the time when purchase application information is received from each purchase application terminal through the group purchase server or at the cost of all purchases. The stage (or means) in which the payment is accepted in advance (taking into account the variable benefits)

- In this step (or means), each buyer applies for purchase and pays in advance all or part of the purchase cost (considering the variable benefits) according to the purchase application price and the purchase application quantity reflected in the purchase application benefit that he/she applies for. This is a step (or means) of guaranteeing one's own purchase application.

If the buyer does not pay the purchase cost in advance before the winning bid benefit is decided (mainly at the time of purchase application), the purchase application may be canceled later without any restrictions and damage to the seller. In the case of cancellation, a partial amount is paid in advance in the form of a cancellation penalty or to strongly express the intention to purchase.

The purchase application status including the purchase application quantity for each purchase application benefit or the cumulative purchase application quantity for each purchase application benefit applied for purchase under the purchase application benefit for each purchase application benefit is sent to the group purchase server through the group purchase server. a step (or means) to be aggregated through;

- In this step (or means), the group purchase server 16 aggregates or to provide.

Here, the cumulative purchase application quantity for each purchase application benefit refers to the total quantity of all purchase application quantities applied for purchase with a benefit that is equal to or worse than the purchase application benefit from the buyer's point of view.

For example, the group purchase server 16 may provide the purchase application status including the accumulated purchase application quantity displayed in the "cumulative" column of FIG. 10 (to FIG. 20).

That is, the "cumulative" in FIG. 10 (~ 20) indicates the accumulated purchase application quantity for each purchase application benefit applied for purchase with less than or equal to each purchase application benefit.

After the group purchase application ends, through the group purchase server,

For each purchase application benefit, the cumulative purchase application quantity requested for purchase with the purchase application benefit less than the purchase application benefit is greater than or equal to the best purchase application benefit among the purchase application benefits corresponding to the section larger than the lower limit of the purchase request quantity section condition When the winning bid benefit is decided by the benefit,

With the purchase application benefits below the successful bid benefit, the purchaser (at least one of the purchasers) who has applied for a purchase is determined as the purchaser who concluded the purchase, and the purchaser who concluded the purchase can purchase the product while receiving the same benefits as the above-mentioned successful bid benefit, as well as the successful bid benefit. A step (or means) of deriving a transaction conclusion result including determining that a purchaser (at least one of the purchasers) who has applied for purchase due to the excessive purchase application benefit is determined as a purchaser who has not been able to conclude a purchase;

- This step (or means) is the step (or means) where the successful bid benefits are determined according to the end of the group purchase application deadline and the results of the transaction including the division into the purchaser who has concluded a purchase and the purchaser who has not entered into a purchase agreement are derived (or means).

(Therefore, unlike the conventional group purchasing method, even though there is a purchase contract, there may be a buyer who is determined to be a buyer who has not been able to conclude a purchase despite the group purchase. )

The description of this step (or means) has been described in detail with the example of FIG. 5 or FIG. 10 (~ FIG. 20) above, so it will not be described in detail.

And, the benefit below a certain benefit refers to a benefit that is equal to or worse than a certain benefit from the buyer's point of view. Therefore, a benefit in excess of a certain benefit means a benefit that is better than any benefit from the buyer's point of view.

Of course, at the discretion of the site operator or the seller or a separate remedy, some or all of the purchasers who have not entered into a purchase agreement are recognized or relieved as the purchasers who have concluded a purchase. Alternatively, the entire purchase may be concluded or part of the cost support may be provided.

A step (or means) that will be explained later, if the purchase cost (mainly reflecting the desired purchase price) paid in advance by the buyer at the time of the purchase application is greater than the purchase cost reflecting the successful bid price, the step (or means) of refunding the difference In , after the refund amount is calculated, it is in the same context as it was said that more than the refund amount calculated at the discretion of the site operator or the seller may be refunded.

In the case where the purchase application price or the price among the conditions of the successful bid benefit is paid among the selected purchase application benefit conditions,

After the winning bid benefit is decided,

Through the group purchase server,

The pre-paid purchase cost (or more) accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to conclude a purchase is refunded (taking into account the variable benefits);

Among the pre-paid purchase costs accepted from the purchase application terminal used by the purchaser who is determined as the purchaser who concluded the purchase, the pre-paid different step (or means) in which the cost (or more) is refunded (taking into account variable benefits);

- In this step (or means), the group purchase server 16 refunds the purchase cost (considering the variable benefits) paid in advance by the purchaser who is determined to be a purchaser who has not been able to conclude a purchase after the group purchase is completed, and the purchaser who has concluded a purchase the payment of a purchase price in excess of the purchase cost of the winning bid reflects pre-payment fee (more) (in view of the fluctuations benefits) steps which reimbursement is (or means).

In other words, the final selling price is determined by the successful bid price, and the purchase cost with the successful bid price is subtracted from the amount paid in advance by the purchaser calculating the purchase cost reflecting his/her purchase request price, and the remainder (considering the variable benefits) ) will be refunded.

Although unlikely, they may give you more money back than the 'remaining' amount above. That is why they said that they would refund 'more than' the difference in cost. In addition, the word 'over' in the reimbursement of other expenses in other parts of the present application is also a word used for the same purpose.

And, since the present invention does not apply for a patent on a method of refunding a part of the amount paid by card, that is, it is not a patent application for electronic payment among patents related to electronic commerce, so the problem to be solved in the present invention is not thought to be, but

Speaking of refunding the amount paid in advance by card,

In other words, let's mention a few things about how to refund the amount (or more) by subtracting the purchase cost with the successful bid price from the prepaid amount to the buyer who paid in advance for the amount exceeding the purchase cost with the successful bid price reflected with the card (Other methods may be possible.)

1. Automate the cancellation of pre-payment (card) and payment of the purchase cost with the newly successful bid price reflected.

2. Charge the amount paid in advance on the card bill as a positive amount, and charge the difference (= the amount equal to the amount paid in advance minus the purchase cost reflecting the successful bid price) as a negative amount, resulting in the successful bid price Arranged by paying the reflected purchase cost.

3. The card company remits the different fees to the customer's account

4. Remit the amount by subtracting the purchase cost reflecting the successful bid price from the amount the seller paid in advance to the customer's bankbook (the seller takes the card fee loss)

5. Accumulate points or cyber money to the credit card company for an amount equal to the amount paid in advance minus the purchase cost with the successful bid price reflected (it can be turned into cash at any time)

6. Accumulate points or cyber money on the operating site by subtracting the purchase cost with the successful bid price from the amount paid in advance (it can be turned into cash at any time)

In addition, the following steps (or means) may be further added to the group purchase method according to the present invention.

In the case where the purchase application price or the price among the conditions of the successful bid benefit is paid among the selected purchase application benefit conditions,

After the winning bid benefit is decided,

Through the group purchase server,

The pre-paid purchase cost (or more) accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to conclude a purchase is refunded (taking into account the variable benefits);

The additional payment for the purchase cost that is insufficient compared to the purchase cost with the successful bid benefit reflected in the pre-paid purchase cost accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has been determined to be a purchaser Step (or means) accepted from the requesting terminal;

-This step (or means) means that when the amount paid in advance by the buyer before the successful bid price is determined is less than the purchase cost with the successful bid price reflected, the buyer pays more for the shortfall. Detailed explanation of this step (or means) will be omitted.

If cancellation of purchase from the purchase application terminal used by any of the purchasers who applied for purchase through the group purchase server is accepted after the purchase has been concluded as the purchaser, the purchase request received from the purchase application terminal used by the purchaser whose purchase application is canceled A step (or means) in which part or all of the paid purchase cost is refunded as a purchase cancellation penalty (taking into account variable benefits) and the remaining balance (or more) is refunded (considering variable benefits);

- In this step (or means), part or all of the purchase cost paid by the buyer in advance will be paid as a penalty in the event that the purchase application is canceled after being determined as the purchaser who has concluded the purchase among the purchasers who have applied for purchase, which may cause damage to the seller. It is a step (or means) to compensate the loss of the seller and to guarantee the reliability of the transaction by recovering it (taking into account the fluctuation benefits) and providing it to the seller.

In other words, from the seller's point of view, all buyers who applied for purchase sold the product by applying for sale by lowering the selling price as much as possible through the calculation of separate multi-storey profit under the judgment that all buyers who applied for purchase would purchase if they were determined to be purchasers who concluded purchases. If it is canceled, even if the successful bid is sold, profits may be significantly reduced or damage may be caused more than originally thought, so a certain penalty is given to the buyer who cancels the purchase application.

The payment for the sales deposit (from the sales application terminal) before the winning bid benefit is determined, including the time when the sales information is transmitted through the group purchase server Byun Byun-hye step (or means) of being accepted in advance);

- In this step (or means), a sales deposit from the seller (mainly) In case the seller does not fulfill his obligations after receiving payment in advance (at the time of application for sale), this is to provide part or all of the sales deposit received in advance to the purchasers who have concluded a purchase (taking into account the variable benefits), and the reliability of the transaction is to secure

After the purchaser has been determined,

If sales cancellation is accepted from the sales application terminal used by the seller through the group purchase server or information that the seller has not fulfilled the obligations under the sales right granted to the seller is received, the pre-paid sales deposit (taking into account the variable benefits) ) is redeemed or

A step (or means) of refunding the sales deposit (or more) to the seller (taking into account variable benefits) when a normal transaction is made;

- As described above, in this step (or means), if the seller cancels the sale without a justifiable reason or does not perform the product provision smoothly, the seller recovers the bid deposit paid in advance in order to compensate for the loss of the purchasers. step (or means).

If a normal transaction is made, the sales deposit will be refunded to the seller.

In the case where the purchase application price or the price among the conditions of the successful bid benefit is paid among the selected purchase application benefit conditions,

After the successful bid benefit is determined through the group purchase server,

The payment for the entire purchase cost compared to the purchase cost with the above successful bid benefit reflected from the purchase application terminal used by a new buyer or a buyer who has been determined to be a buyer who has not been able to purchase is accepted (taking into account the variable benefits);

The purchase cost with the above successful bid benefit reflected in the pre-paid purchase cost accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to conclude a purchase due to a purchase application benefit exceeding the above-mentioned successful bid benefit Including that payment for insufficient purchase costs is accepted from the purchase application terminal used by the purchaser who is determined to be a purchaser who has not been able to conclude a purchase (taking into account the variable benefits)

As the purchase application is accepted with the above winning bid benefits, including the acceptance that the total purchase cost is settled (taking into account the variable benefits),
