Description

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

SNS-linked joint purchase method.

Nowadays, joint purchases linked to SNS sites are gaining in popularity.

SNS is an abbreviation of Social Networking Service, and refers to a service that can establish a relationship with an unspecified person online. Users build new connections through SNS or strengthen their relationship with existing contacts. Representative examples of SNS sites are Twitter or Facebook.

If a joint purchase site announces that if a certain quantity of purchase requests for a certain product is applied for a certain quantity, it will announce a joint purchase that sells the product at a significantly larger discount rate. You will be able to participate in the joint purchase by obtaining the joint purchase disclosure information for. In particular, when SNS sites such as Twitter or Facebook encourage members to participate in joint purchases, many buyers participate in joint purchases, or social commerce.

Representative examples of such co-purchase sites are Groupon ( http://www.groupon.com ) in the United States and Ticket Monster (http://www.ticketmonster.co.kr/) in Korea. In Korea alone, there are a number of SNS co-purchase sites, including Ticket Monster, which all saw the success of Groupon in the US and entered the co-purchase business.

As the method of making SNS joint purchase is relatively simple, entry barrier is very low, and competition among companies is very fierce, and many businesses are closed. Without a specific strategy, they all operate in almost the same way.

However, there is one major problem in the conventional SNS co-purchase method.

 As shown in FIG. 1, only one purchase request price to which one discount rate is applied according to one purchase request quantity section is in progress of joint purchase.

Buyers applying for SNS joint purchases are expected to be able to buy at a discounted price of up to 50%. This is because most SNS joint purchase disclosures can be traded at a discount of 50% if a certain amount of purchase requests are made. In fact, the 50% discount has almost no margin. It's hard to make a profit without an incredibly large volume.

In such a situation, if the joint purchase must proceed so that one purchase request quantity section and one purchase request price exist as in the conventional method, a huge amount of goods that are rarely requested to be purchased must be applied for a purchase and then a 50% discount is required. When a seller makes a joint purchase announcement that they can trade at the same price, buyers are likely to blame, so that the seller can trade at a discounted price of about 50% even if the quantity is not a large quantity. You have to do it. That is, in the conventional method, an excessive discount rate is inevitably applied to the quantity requested for purchase . In such a situation, even if the quantity applied for the purchase meets the disclosure conditions, even if the transaction is concluded, the margin is almost 50% discounted (or at a loss price) . (Or lose ) In other words, the conventional SNS-linked joint purchase is not a strategy for large profits by peeling off, but is almost always a public announcement to proceed with the joint purchase only for the purpose of promoting the business , there is no problem in the quality of service It is a structure, and sellers cannot make frequent joint purchases. In addition, a seller who sells a product that can not be discounted by 50% without a huge quantity, or a seller who does not want to sell at a discount of 50% can even think of proceeding with the SNS joint purchase by this conventional method. You can't.

Let's look at the problem in more detail by reading a newspaper article.

The interview with Shin Hyun-sung, CEO of Ticket Monster, the leading social commerce company in Korea (2011.01.11) also indirectly shows the problem of conventional social commerce.

“ Nearly 500 websites (= social commerce companies ) have been created. Customer complaints are growing about domestic social commerce services. There are a lot of places that sell poor quality products or close for a short time. Timon will be picking up companies since this year, and will also conduct on-site visits and training. There are also challenges for businesses to promote as effectively as they think when selling things with social shopping services. We will be creating a new channel for these traders to communicate directly with their customers. ”

Looking at the above interviews, only the promotional effect is emphasized, and many of the benefits of peeling off are not discussed at all. However, in many cases, even the promotional effect is insufficient. This is because there are many people who are chasing only low prices or being enthusiasts. Thus, there are many damages that only cost a lot of damage.

The KBS 'Consumer Accumulation' program evaluated as follows.

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

Social commerce that can use products or services at discounted price through joint purchase through the Internet! The social commerce site, which sells various products such as food, performances, beauty and education, first appeared in Korea in March 2010. The social commerce market is growing so fast that coupon sales amounted to about 60 billion won last year. Consumer damage is also on the rise. Visiting businesses with discount coupons purchased through social commerce will be treated differently from ordinary customers. Is it true?

A steakhouse visited for confirmation. The crew ordered the same menu by dividing the discount coupon guest team and the regular guest team. Plate of discount coupon visitor team that looks worse than general visitor team at first sight. Not only was the amount of meat different, but there was a difference in the overall menu. In addition, some social commerce companies were asking the service providers to issue excessive coupons. These discount coupon abuses prevent consumers from receiving proper service.

"Consumer accusation" reported the problem of 'Social Commerce' which is not properly serviced due to the price discount. "

In addition, there are articles that the Fair Trade Commission has expressed concern about due to excessive discounts and operational problems of social commerce companies.

"The side effects of social commerce were so severe that the Fair Trade Commission began investigating the damage situation on August 8. Officials of the FTC said," We will come up with measures after grasping the specific situation against several companies of the national scale. " The FTC issued a report of consumer avoidance last November regarding social commerce . "

In Korea alone, as of 2011.1.1, there are about 500 social commerce companies. At least 10,000 social commerce companies are expected to exist worldwide. It's the same as Groupon. Therefore, the press is also talking as follows.

"Social commerce rush, lack of strategy"

"We find that there is no strategy other than preemption."

"If you add your own success factors, you can survive the market."

In addition, an analysis showed that Groupon is likely to follow the train of online auction company eBay. The online coupon business initially caught the attention of consumers, but soon became popular and is typical of Internet services .

It is argued that the method of the present application is necessary in such a situation.

Now, as shown in FIG. 1, the problem of the conventional method in which the joint purchase is made so that there is only one purchase request price to which one discount rate is applied according to one purchase request quantity section will be described in detail.

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

Co-purchase proceeds so that only one purchase request quantity section including the “more than 500” section of FIG. 1 and one purchase request price to which one discount rate is applied are present.

Therefore, the number of purchases applied for joint purchase was considerably higher, such as 490, as shown in FIG. 5, and 350 purchases were satisfied even if only the 30% discount rate was applied instead of the large discount rate of 50% discount rate. Although there were quite a few (= 40 + 130 + 180), all of the 490s did not close at least some of the 490, because none of the discounts presented in the co-purchase announcement, such as 500 in FIG. 1, were satisfied. There are many cases in which transactions cannot be closed.

[Details for carrying out the invention] In the situation where a purchase request quantity of 490 purchases as shown in Figure 5 or 6 described in detail as an embodiment of the method of the present application in the unit 1 as in the conventional method as shown in FIG. Although the lower limit of the purchase application quantity section in which only the purchase application quantity section exists exists was not achieved, the present method makes 350 purchase application quantities available for purchase, but in the conventional method, even one purchaser can purchase. This is causing too much opportunity loss for the buyer or seller.

In the SNS joint purchase, as shown in FIG. 2, obstacles in proceeding with the joint purchase are removed in a rational manner so that there are a plurality of purchase request prices with different discount rates applied to the multiple purchase application quantity sections.

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

B: Additional discount amount = C * D / E

In the formula for B above,

C is the number of the purchase offer price in the section to which the total purchase order volume belongs, minus (or close to) the price of the purchase request in the next section (toward the larger quantity of purchase requests) of the section to which the total purchase order quantity belongs.

D is the total number of purchases minus the lower limit of the interval to which the total number of purchases belongs (or a number close to it).

E is the lower limit of the next section of the section to which the total purchase order quantity belongs, minus the lower limit of the section to which the total purchase order quantity belongs (or a number close thereto).

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

In the SNS joint purchase, the joint purchase may be performed such that there are a plurality of purchase request prices with a specific discount rate for each purchase request quantity section such as “150 or more” section, “300 or more” section, and “500 or more” section in FIG. 2. It is in itself a solution to the long-standing wishes of sellers , and a reasonable bid price can be determined as long as the total quantity applied for purchase in the joint purchase is calculated .

In the meantime, it is possible to reduce the loss of opportunity that has occurred in the past, to satisfy more buyers and more sellers, and to close the deal at a lower discount rate , so that sellers can obtain an appropriate margin. As a result, the quality of the product can be improved and the seller can frequently make joint purchases, thereby further activating joint purchases, especially joint purchases with one seller such as SNS-linked joint purchases.

Even if the joint purchase proceeds to include a purchase application quantity section that does not apply a discount at all, such as the section "less than 150" of Figure 4, a lot of cases that the buyer or seller can be satisfied.

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

When the joint purchase can be disclosed such that there are a plurality of purchase request prices with a certain discount rate for each of the multiple purchase request quantity sections as in the present method , a discount of about 50%, which is a price with almost no margin for only a very large quantity, as shown in FIG. If they announce that they can trade at a price, and that they can trade at a discount of 15-30%, the buyers also have a 50% discount. There are no complaints, and even if the seller concludes the transaction with a small quantity, the price is determined by the winning price, which has a margin with a small discount rate. Will be. Thus, there is no problem in quality, and sellers can often make joint purchases. From the buyer's point of view, the 30% discounted price and the 50% discounted price appear to be only 20% off the buyer's point of view, but in the case of sellers, the 30% discounted price is 50% discounted considering the margin per unit price. You might have a 10x margin than you sell. Therefore, in FIG. 5, a discount rate according to a purchase application quantity section is illustrated to make it easier to understand the embodiment description of the present application as 15% discount if more than 150 quantity, 30% discount if more than 300 quantity, and 50% discount if more than 500 quantity. But

For the seller, as shown in Fig. 8, a 15% discount for more than 150 quantities, a 30% discount for more than 500 quantities, and a 50% discount for more than 3000 quantities may be a reasonable configuration. According to the method of the present application, 15% discount if the seller is more than 150 quantity, 30% discount if the quantity is more than 500 quantity, 50% discount if the quantity is more than 3000 quantity, the joint purchase announcement is reasonable. Margins can be obtained and it is difficult to apply for purchase of 3000 units (or the seller, as shown in Figure 9, 15% discount if more than 25 quantities, 30% discount if more than 100 quantities, and 50% discount if more than 500 quantities can be a reasonable configuration. According to the method of the present application, 15% discount if the seller is 25 quantities or more, 30% discount if the quantity is 100 quantities or more, and 50% discount if the quantity is 500 quantities or more You can get a significant gross margin, and it's hard to get 500 purchases, but you'll still be able to get a gross margin so you can be satisfied. Open, if only as a conventional method to disclose the joint purchase one purchase application rates according to one purchase application volume interval only to jonhae, when more than 3000 Quantity simply disclose that a 50% discount 3000 quantities yiraseo too large quantities, then It is unlikely that the deal will be concluded because the volume of purchases is not applied for purchase, and the seller may be criticized by the buyer for disclosing that it was for promotional purposes rather than selling. Since the co-purchase announcement is made, even if 500 pieces are applied for a purchase and the transaction is made at a 50% discount price, the seller has no margin and it is difficult for the seller to be satisfied on the margin side. In many cases, only the public relations effect can be expected. In fact, in most cases, the PR effect is insufficient. Many people are chasing only low prices.

And, it is still active to distribute only the products in the service sector in the social commerce co-purchase method, using the method of the present invention can also enable the social commerce co-purchase co-products.

In fact, the cost of industrial products is high and the margins are often inherent, so only a few products can be sold at a discount rate of around 50%.

In such a case, various discount rates must be presented as in the present method so that various kinds of industrial products can be distributed in a social commerce manner.

Also, even if the purchase application quantity section is changed, joint purchases are made in the form of purchase application benefits corresponding to each purchase application quantity section so that there is no price change or an extremely small price change. Products that are paid for are also useful because they do not become a factor in choosing application benefits, but they are free from the outset, such as insurance, internet subscription, and mobile phone subscription. Sellers can be more profitable in terms of margin.

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

 In order to make it easy to understand this application, it demonstrates from an Example.

Although an example is given of the service goods of food, it is obvious that industrial products are also possible.

In one restaurant, steak A is usually sold for 10,000 won.

However, at a joint purchase site, a joint purchase event was held for a stake named A. Suppose the joint purchase was announced while making the joint purchase condition as shown in FIG.

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

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

 For each buyer, he would apply for a purchase, expressing his own purchase offer price and the quantity of purchases that he would like to fulfill.

(Of course, it is also possible to apply for a purchase by saying that each buyer wants to buy more than one product.)

The purchase offer price from the buyer's point of view is the maximum price at which he can accept the purchase.

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

If the successful bid price exceeds 7,000 won,

If the successful bid price is less than 7,000 won, he expressed his intention to implement the purchase.

Then, during the purchase application, even though the successful bid price has not yet been determined, each purchaser pays for the purchase cost reflecting the purchase request price expressed.

Payment methods vary. Examples of payment methods include deposits, reserves, various points, credit cards, account transfers and mobile phone payments. There are also various ways of reimbursement. And, such a payment system will not be described in detail because it can be easily implemented by ordinary e-commerce technicians.

Suppose that the result of applying for a purchase in the joint purchase disclosure as shown in FIG. 4 is as shown in FIG. 5.

It should be noted that the number of products expressed in the number below also includes the number of countless service products including beauty salon services and nail care services. For example, even if the number of services is expressed as a number, it will not be difficult to understand the method of the present application.

Although the following embodiments are mainly described using the number, but the same principle is applied to the number of products or the number of times it will be obvious to anyone, so will not be described in detail separately.

 Referring to Figure 5,

A total of 490 items have been applied for purchase in the joint purchase. Among the 490 items,

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

There were 130 purchase requests at the purchase request price of 8,500 won.

There were 180 requests for purchase at the price of 7,000 won.

You can see that there were 140 purchase requests at the purchase request price of 5,000 won.

Regardless of the number, it is possible to purchase at 10,000 won, which is a price without any discount, so the “satisfaction” column in the “less than 150” line of the “purchase application quantity section” column is “satisfaction”,

(To explain a little bit more,

If it is less than 150, it is announced that it will be supplied at the normal price of 10,000 won, and there are 40 accumulated total number of purchases at the purchase price of 10,000 won, and the lower limit of the "purchase application quantity section" in the row is, in fact, 1 As a result, it is possible to conclude that the deal can be concluded at the usual price, so that the "satisfaction" column in the "less than 150" row of the "purchase application quantity section" column is satisfied.)

If it is more than 150, it is announced that it will be supplied to the price of 8,500 won with the 15% discount applied. As it is 150, it is possible to conclude that the deal can be concluded at a 15% discount price. "ego,

If it is more than 300, it is announced that it will be supplied to the price of 7,000 won, which is a 30% discount. The cumulative number of purchases made at the purchase request price of 7,000 won or more is 350. As a result, it is possible to conclude that the deal can be concluded even with a 30% discount price, so the "satisfaction" column in the "300 or more (= 300 ~ 499)" column of the "purchase application quantity section" column is "satisfied". ego,

If it is 500 or more, it is announced that 50% discount will be applied to 5,000 won. The cumulative number of purchases made at the purchase request price of 5,000 won or more is 490, which is the lower limit of the “purchase application volume section” in that row. Since it is smaller than 500, it can be concluded that the contract can not be concluded at the 50% discount price, so the "satisfaction" column in the "over 500" line in the "purchasing volume" column is "unsatisfactory".

As described above, there are two methods for determining the winning price.

The first way is

For each purchase request price, the purchase request for which the cumulative purchase order quantity purchased above the purchase request price is greater than the lower limit of the purchase order quantity interval condition (where the bid price may be determined at the purchase request price). The lowest purchase price among the prices is determined as the winning price .

The bid price is 7,000 won, which is the lowest of 10,000 won, 8,500 won, and 7,000 won, which corresponds to the quantity of purchase requests where "satisfaction" is "satisfied".

In addition, the cumulative number of all 350 items applied for purchase at the purchase price of 7,000 won or more, which is the successful bid price, can be traded at the same price of 7,000 won.

In other words,

Buyers who apply for a purchase request price of 10,000 won can purchase it for 7,000 won,

Buyers who apply for a purchase request price of 8,500 won will be able to purchase for 7,000 won.

Of course, buyers who apply for a purchase request price of 7,000 won will be able to purchase for 7,000 won.

The term "purchasable" will be described as passing the application for purchase, and "purchasing" is the same.

In addition, 140 bids purchased at the purchase price of 5,000 won less than the bid price of 7,000 won will be impossible to purchase. The term "purchasing impossible" will be described as failing a purchase application, or "purchasing cannot be made."

And, when applying for a purchase, even before a successful bid price is determined for each buyer, since the purchase price that reflects the purchase request price in consideration of the amount of the purchase request price multiplied by the quantity of the purchase request is paid in advance,

Buyers who are no longer able to purchase can be reimbursed for the amount they paid in advance at the time of application for purchase, and the goods can not be supplied.

The purchaser who is able to purchase the product can be supplied while refunding the amount excluding the purchase cost (= successful bid price multiplied by the purchase request quantity) reflecting the successful bid price from the amount previously paid at the time of the purchase application.

To explain in more detail,

The purchase price is 5,000 won, which is lower than the successful bid price of 7,000 won, and the buyer who applied for the purchase of 140 purchases of 5,000 won in advance is refunded 5,000 won in advance, and the product is not supplied. Because the purchase price is lower than the successful bid price, it is not available for purchase.

For 180 buyers who applied for a purchase of 7,000 won in advance while purchasing a purchase price of 7,000 won, which is the same as the successful bid price, the cost differs from 7,000 won per piece, which is the prepaid amount, and 7,000 per piece. The product is supplied with a refund of 0 won per person. In other words, a refund of KRW 0, which is the difference between the winning price and the amount paid in advance, means that there is no refund.

Buyers who purchased a purchase price of 8,500 won, which is higher than the winning price of 7,000 won and applied for the purchase of 130 pieces of 8,500 won in advance, were paid 8,5000 won per piece and 7,000 won each. The product is supplied with a refund of 1,500 won per piece, which is a different cost.

For buyers who apply for purchases for 40 purchases of 10,000 won each, which are 10,000 won higher than the winning price of 7,000 won, the buyer pays 10,000 won for each purchase price and 7,000 for each winning price. The difference is the cost of 3,000 won per piece, the product is supplied.

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

For each purchase request price, the purchase amount corresponding to the period in which the cumulative purchase order quantity purchased above the purchase request price is larger than the lower limit of the condition of the purchase request quantity interval (where the bid price may be determined at the purchase request price). It is a method in which a specific price is determined as a winning price among the prices below the lowest purchase request price among the applied prices.

In other words, the discount can be applied in addition to the winning price by the first method.

As a further discount method is conceived, a great variety of methods can be devised, that is, an infinite number of methods.

As for the additional discount limit, the price after the additional discount is at least equal to the purchase offer price corresponding to the next purchase request section of the section to which the winning price by the first method belongs (to the larger order). It is recommended. In the following example, it is recommended that the price after the additional discount is 5,000 won or more. (If the bid price by the first method belongs to the next purchase request volume (toward the larger purchase volume) If there is no, for example, in Figure 5, if the total purchase amount is more than 500, there may be no additional discount, a separate additional discount method may be applied.)

In addition, one example of various methods of applying a discount will be described as an example.

 According to the first method, a 30% discount applies to 300 or 499,

According to the second method, 300 pieces are 30% discounted and 490 pieces are 49% discounted.

So, even if a buyer applies for a purchase of 7,000 won, if the total purchase application quantity is 490, a 49% discount can be made so that the selling price is about 5,100 won.

To explain in more detail,

Sale price = A-B = 7,000-1,900 = 5,100

In the above bid price formula,

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

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

In the formula for B above,

2,000 is the number of purchase requests for 490 sectors, which is 7,000 won, minus 5,000 won for purchases in the next sector of the 490 sectors.

190 is the total number of purchases (490) minus 300, which is the lower limit of the 490 section.

200 is the lower limit of the next section of the section to which the total number of purchase requests (490) belongs, minus 300, which is the lower limit of the section to which 490 belongs.

Those skilled in the art and those skilled in the art will be able to easily think of another additional discount method other than the additional discount method of the above embodiment, and thus no further methods will be listed.

(But let me introduce another additional discount

Among co-purchasers, customers who apply for a large quantity (e.g. 20) can make a successful bid price at a discounted price or a certain percentage of the purchase offer price corresponding to the section that includes the total purchase order quantity. Maybe,

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

However, if the additional discount rate in this way is too large, the intention of the discount effect may be diminished even by joint purchases between unspecified people. (5% additional discount is recommended, up to 10% additional discount) Anyway, depending on your contribution, you can give additional discounts.)

When purchasing a large quantity, one may apply for purchase by one specific person, but each buyer may have to express himself as a person who pursues a joint purchase with a certain buyer.

If the seller permits, for each purchase request price, which is not possible with the current cumulative purchase order quantity, for each purchase request price, the amount of the purchase request that has been applied for purchases above the purchase request price may be determined by the purchase request price. The bid price may be determined even if the price is less than the purchase offer price corresponding to a section smaller than the lower limit of the application quantity section condition.

And Facebook, a US social network company, already offers promotions that let my friends know that I've paid with Facebook credits and give me a discount if my friends make a purchase again. Similar discounts can be given.)

Here, in the second method, if you make a purchase request, even before the bid price is decided for each buyer, you paid in advance for the purchase cost that reflects the purchase request price, which is the product of the purchase request price multiplied by the purchase request quantity.

Buyers who are no longer able to purchase can be reimbursed for the amount they paid in advance at the time of application for purchase, and the goods can not be supplied.

The purchaser who is able to purchase the product can be prevented from supplying the product by refunding the amount paid in advance at the time of the application for purchase, excluding the purchase cost (= bid price multiplied by the purchase application quantity) reflecting the successful bid price.

To explain in more detail,

The buyer who applied for the purchase of 140 purchases of 5,000 won each by applying for a purchase 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, refunds 5,000 won each. The product is not supplied, because the purchase price is lower than the successful bid price, and it is not available for purchase.

For 180 buyers who made a purchase request of 7,000 won and paid 7,000 won in advance, the buyer who applied for a purchase of 7,000 won reimbursed 1,900 won each, which is a difference between 7,000 won, which is the prepaid amount, and 5,100, which is the winning price. The goods are supplied.

Buyer who applied for purchase with a purchase price of 8,500 won higher than the successful bid price of 5,100 won, and applied for the purchase of 130 pieces of 8,500 won in advance, 8,5000 won per piece and 5,100 each for the bid price The product is supplied with a refund of 3,400 won per piece, which is a different cost.

For buyers who apply for purchases at the price of 10,000 won, which is higher than the winning price of 5,100 won, and apply for the purchase of 40 pieces of 10,000 won in advance, the amount paid in advance is 10,000 won for each purchase price and 5,100 for each successful bid price. The difference is the cost of 4,900 won per piece, and the goods are supplied.

When the joint purchase proceeds to methods that can be derived from the method of the present application including the method of the embodiment having the concept of a successful bid price or a refund according to the first method and the second method as described above,

Many buyers who are satisfied with a small discount rate can make purchases, thereby reducing the opportunity loss of buyers and sellers.

If there is a sale disclosure that a product is to be supplied at a discount of 50% only when 500 or more products are applied for purchase as in the prior art, there are no buyers who can purchase even though 490 are applied for purchase.

According to the method of the present application, 350 of the 490 applied for purchases can be a transaction, it can be seen that the conventional method had a great opportunity loss to the buyer and seller compared to the method of the present application.

In addition, even though the purchase price is higher than the successful bid price, the purchase price can be purchased at the same price as the successful bid price. There is no need to apply for purchase only at the purchase offer price.

For example, a buyer who is satisfied with a 15% discount may apply for a 15% discount, but the winning price may be set at a 30% or 50% discount (or other discount rate). Expecting to be able to apply for a purchase. If the amount discounted by 30% or 50% (or other discount rate) is determined as the winning price, the amount 30% or 50% (or other discount rate) is discounted even though you applied for the 15% discount offer price. This is because it becomes available for purchase.

Even if a buyer who is satisfied with a non-discounted price, who is trying to buy anyway without a discount, applies for a non-discounted purchase price, a 15% or 30% or 50% (or other discount rate) is discounted. It is possible to apply for a purchase with the expectation that the winning price may be determined based on the amount. If the amount discounted by 15% or 30% or 50% (or other discount rate) is determined as the winning price, 15% or 30% or 50% (or other discount rate) may be applied even though the applicant has applied for a purchase price that has not been discounted at all. ) Becomes available at a discounted price.

In the end, when making a purchase request for joint purchase by the method of the present application, one only needs to apply for a purchase at a price with a satisfactory discount rate. Only the buyer needs to apply for a very low price with a very high discount rate.

Buyers will be able to focus more on promoting themselves to attract more buyers.

In addition, as shown in FIG. 6, the "satisfaction" occurred in the section in which the purchase application quantity is "150 or more", but the "satisfaction" column is "satisfaction" in the section in which the number of purchasers is "300 or more". It will not need to be explained that the purchase price of 7,000 won, which is the lowest price among the purchase request prices corresponding to the “satisfied” purchase request quantity section, “300 or more”, becomes the winning price.

At the initial time of applying the method of the present application, the joint purchase has been performed so that only one purchase request quantity section and the purchase request price correspond to each other. If they exist, buyers may not accept it

First, it is recommended to proceed with the joint purchase so that there are two purchase application quantity intervals as shown in FIG. 21, and gradually increase the purchase application quantity interval.

Compared to the situation where only one purchase application quantity section can exist, only having two purchase application quantity sections can exert a tremendous effect.

For reference, if each purchaser does not express his or her own purchase price and the quantity of purchases that he wishes to carry out the purchase at any price,

Proceed joint purchase so that there are a plurality of purchase request prices with different discount rates for each purchase request quantity section, such as “150 or more” section, “300 or more” section, and “500 or more” section in FIG. 2 (or 4). I will explain the failure .

 Assume that a plurality of buyers have acquired disclosure information on the joint purchase process 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 Does not select a satisfactory purchase price, but assumes that a lot has been applied for by a large number of buyers .

Then, a problem arises that the selling price cannot be determined even though the total purchase application quantity is calculated after the joint purchase application is closed. Let's see why.

The total purchase volume of 470 items belongs to the "300 or more (= 300 ~ 499)" purchase application quantity section in the joint purchase announcement, so the successful bid price is 7,000 won per 30% discount rate. If the payment is completed in won and the transaction is completed, there is no problem, but it is not possible.

This is because the psychological state of each buyer who applied for 470 purchases may be as shown in FIG. 3. (Fig. 3 does not show that the buyers actually apply for the purchase by selecting their own purchase price, only the psychological state at the time of the purchase request.)

Referring to Figure 3, out of the total purchase volume of 470, 180 were made for purchase with the price of 5,000 won per 50% discount rate applied, and the bid price was determined to be 7,000 won per piece, so that 180 purchases were made. It is expected that this will be canceled.

Since the purchase price was not selected for each buyer at the time of the purchase request, in a real situation, since the seller or each buyer does not know that the psychological state as shown in Fig. 3 is analyzed, when and how much will be canceled? Do not know. It can be seen after the expiration date for each buyer to express their intention as to whether to make a purchase or cancel the purchase at the price of 7,000 won each.

After the deadline for making a statement, 180 purchase requests were canceled with the purchase price of 5,000 won in mind. The remaining quantity is 290 (= 470-180), and 290 are joint purchase announcements. The bid price is readjusted back to 8,500 won with a 15% discount rate because it belongs to the “150 or more (= 150 ~ 299)” purchase request volume.

(However, some buyers are often unacceptable to reschedule the bid price, because some buyers think that the bid price should be 7,000 won because the first 470 purchase orders are initially applied. However, from the seller's point of view, the remaining 290 purchase orders should be 8,500 won (and the bid price will be 7,000 won), and the margin is too small to sell for 7,000 won. Too many things happen if you think you might lose money.

And, (although it's actually very difficult to overcome this situation in online purchases that must go fast, even if it's only agreed to overcome this situation)

The purchaser who applied for the purchase of 290 quantities should collect the expression of intention of each buyer as to whether to make a purchase or cancel the purchase at a bid price of 8,500 won each.

It's virtually impossible to get each buyer's intention once again, but anyway, once again,

Of the 290 purchase requests, the bid price of 8,500 won was accepted for 140 items that were purchased with the purchase price of 8,500 won in mind from the beginning. Since the number of purchases is canceled, the remaining quantity is 140 (= 290-150), and 140 pieces do not belong to the section "150 or more (= 150 ~ 299)" in the joint purchase announcement. There are too many cases of refusing to sell even 8,500 won with a 15% discount rate. Thus, as shown in FIG. 2, it is often impossible to make a joint purchase announcement so that a plurality of purchase application quantity sections exist.

Fig. 2 shows three purchase application intervals presented by the seller, so that each purchaser expresses his or her opinion on the initial bid price or the changed bid price only two times. If the joint purchase disclosure is made so that the number of purchase application quantity sections exists, the more the number of purchase application quantity sections is, the more the number of times to collect the expression of intention increases, so that the joint purchase disclosure is made such that there are multiple purchase application quantity sections as shown in FIG. It becomes impossible to do.

As such, as shown in FIG. 2, a joint purchase disclosure is made to include a plurality of purchase request quantity sections, and in the method of applying for a random purchase without selecting a purchase request price of a level satisfactory to each buyer at the time of the purchase request,

It is virtually impossible to convince each buyer of the intention of buying or canceling the purchase at the initial or changed bid price multiple times, and each bidder performs the purpose of guaranteeing the purchase intention. Even before the price is determined, it is unimaginable to pay in advance a payment or a deposit that reflects the purchase offer price, the maximum amount each buyer can pay for the purchase of the product.

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 may seem that there is no difference between paying after the winning price is determined, or paying before the winning price is determined, and paying after the winning price is determined, but the joint purchase can proceed. There is not.

Buyers may be wondering that they pay a price that is satisfactory before the winning price is determined.

From the seller's perspective,

After the successful bid price is determined, there is a high probability that among the buyers who have signed up for a joint purchase, the buyer who does not make a payment

Before the successful bid price is determined, that is, when each purchaser pays a price that is satisfactory to him, the probability that a buyer who cancels the payment among the buyers who apply for the co-purchase cancels the payment.

Because it's much bigger.

In other words, if the purchase intention decreases between the time of the joint purchase application and the time of the successful bid price is decided, or it is bothered to make a payment by visiting the site once again or missed the payment deadline or fail to pay. Occur a lot  because of.

From the buyer's point of view

It is also annoying to visit the site once again and make a payment after the successful bid price is decided.

Buyers who are engaged in co-purchasing at the slightest price only with a high discount rate have a very high chance of avoiding payments.

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

The electronic commerce system 10 for the implementation of the joint purchase method according to the present invention, one or more purchase request terminal 12 that can be used for the purchase application of the unspecified number of buyers, or (mainly one person (or one company) A sales application terminal 18, or a co-purchase server 16 that operates an online site on which co-purchase is performed, or a network communication network 14 including the Internet for communication.

(In entering sales information,

The site operator receives the sales information from the seller, the site operator may input the sales information through the terminal used by the site operator, or the seller may directly enter the sales information through the sales application terminal used by the seller.

If the seller directly inputs the 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 sales operator receives the sales information from the seller and inputs the sales information through the sales application terminal used by the site operator, the sales application terminal 18 used by the site operator may be required. In any case, a sales application terminal is necessary.)

The purchase request terminal 12 checks the joint purchase progress information by accessing the joint purchase server 16, and enters the purchase application information or jointly if the buyer wants to purchase a specific item through the joint purchase. Client terminal used to receive purchase progress information.

The sales request terminal 18 is a client terminal which is used by the seller to access the joint purchase server 16 to input his joint purchase condition information and to confirm the joint purchase progress information.

Co-purchase progress If the site operator receives the contents of the co-purchase condition from the seller and then enters the co-purchase condition information directly, the site operator may not need the sales request terminal used by the seller. However, considering the terminal of the site operator as the sales request terminal, it may also be said that the sales request terminal 18 is necessary.

The joint purchase server 16 operates an e-commerce site based on the joint purchase method, and provides joint purchase progress information, receives the purchase request information from the purchase request terminal 12, and stores the sales request terminal 18. Co-purchase disclosure information (or sales information) is received and stored, and the co-purchase progress process is processed.

In addition, since the joint purchase method according to the present invention includes a process in which the joint purchase server 16 side prepays and refunds the amount from the buyer or the seller, the joint purchase server 16 may include a separate payment server (not shown). It may be implemented to be linked or perform its own payment function, and the co-purchase server 16 may also be linked with a separate sales server (not shown) to provide information about the sale product.

The e-commerce system 10 is very similar to the conventional e-commerce system for a general social commerce co-purchase shopping mall, Internet shopping mall, Internet auction site, the present invention is different from the conventional method of operating a joint purchase, accordingly It is only necessary to change the operation program provided on the joint purchase server 16 side, and those skilled in the art will be able to implement the present invention smoothly within the scope of the conventional e-commerce system construction technology without having to describe the legacy system in more detail.

The co-purchase method according to the present invention is a co-purchase method on an e-commerce in which a seller (mainly one person) and one or more (mainly many) buyers can participate in the same product at the same time, and each buyer The purchase application information is entered by entering the purchase application information including the purchase application price corresponding to the maximum price that can be paid for the product to be purchased and the quantity of the product to be purchased within the available purchase application time.

A purchase application status including a purchase request amount for each purchase request price or a cumulative purchase request amount for each purchase request price applied for purchase above the purchase request price is counted through the joint purchase server through the joint purchase server,

After the joint purchase application, through the joint purchase server,

For each purchase offer price, the purchase offer price corresponding to an interval in which the cumulative purchase order quantity purchased above the purchase offer price corresponds to an interval greater than the lower limit of the purchase order quantity interval condition (where the bid price may be determined at the purchase offer price). As a specific price among the prices below the lowest purchase offer price is determined as the winning price,

The transaction conclusion result including the decision that the buyer who applied for the purchase price above the successful bid price is determined to be the buyer who concluded the purchase and that the buyer who applied for the purchase price below the successful bid price is determined to be the buyer who failed to purchase It is provided or notified to the connected terminal including the sales application terminal.

Accordingly, a buyer determined as a purchaser who has not purchased the medium may be generated even though there is a purchaser who has concluded a purchase unlike the conventional joint purchase method .

The purchaser can input his / her purchase request information including the purchase request price and the quantity of the purchase request, and pay for some or all of the corresponding purchase costs in advance to guarantee his purchase request, so that the joint purchase server will be (16), after the successful bid price is decided, the buyer who cancels the purchase application even though the purchase price has been concluded, pays the sellers by repaying some or all of the amount paid in advance in the form of cancellation cancellation penalty. Seller's loss due to cancellation shall be compensated.

In this way, all buyers applying for purchase can be guaranteed to execute the purchase.

Of course, the joint purchase server 16 immediately refunds the prepaid amount when the prepaid buyer is determined to be a buyer who cannot be concluded according to the result of the joint purchase, while the prepaid buyer is a buyer who has already made a purchase. If determined, replace the prepaid amount with the purchase cost of the product, but calculate and refund the difference paid in advance in excess of the purchase cost reflecting the winning price.

In addition, if the seller also pays a predetermined deposit in advance to cancel the sale or the product delivery to the buyer smoothly even after a successful bid price is determined, the joint purchase server 16 collects the deposit paid in advance and purchases it. By providing to the concluded buyer, the loss of the buyer due to the cancellation of the seller can be preserved, and also the reliability of the transaction can be secured.

In addition, according to the present invention, the joint purchase server 16 does not close the transaction at the purchase request price purchased by each buyer, all buyers determined as the purchase buyer can purchase the product at the same price called the successful bid price Therefore, one joint purchase can satisfy a large number of buyers as much as possible. (A buyer having a complaint can prevent occurrence brightness 1).

In this regard, the joint purchase server 16 basically receives the purchase cost calculated in consideration of the purchase request price and the quantity of the purchase request applied by each buyer before the successful bid price is determined (mainly, at the time of the purchase request). Therefore, the difference in cost between the purchase cost prepaid by each buyer and the purchase price reflecting the successful bid price is calculated and refunded for each buyer immediately after the decision to purchase the purchase.

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

(Step (or means) of the joint purchase announcement information, including the purchase request price corresponding to the two or more purchase request quantity section for the transaction target product to the joint purchase server;)

-This step (or means) is the seller of the joint purchase conditions, including the different purchase request price corresponding to the different discount rate can be applied to two or more different purchase request quantity section for a particular product as shown in FIG. Is a step (or means) provided to the site administrator and entered by the site administrator or directly by the seller.

It is obvious that different purchase offer prices do not correspond to the different purchase request quantities in the joint purchase announcement, and that even if a specific discount rate corresponds to different normal prices, different purchase request prices are considered to correspond. It belongs to the scope of rights. This is because applying a discount rate to the usual price results in a discounted price.

Through the joint purchase server, the joint purchase disclosure information including the purchase request price (where a specific discount rate can be applied) corresponding to two or more purchase application quantity sections for a transaction target product is purchased. (Or sales application terminal: SS ?) To connected terminal including Accepted  Step (or means)

-This step (or means) is the seller of the joint purchase conditions, including the different purchase request price corresponding to the different discount rate can be applied to two or more different purchase request quantity section for a particular product as shown in FIG. Is provided to the site administrator so that the joint purchase disclosure information entered by the site administrator or directly entered by the seller can be displayed on the purchase request terminal.

 When a specific discount rate is applied to two or more purchase application quantity sections, it is recommended to have a different discount rate for each purchase application quantity section. However, even if it is a different section, joint purchase may be performed so that the same discount rate is applied if necessary.

In addition, the specific discount rate may be 0%. That is, there may be a purchase application quantity section to which the price is normally applied.

From the purchase request terminal used by each buyer, the purchase request price of any one of the two or more purchase request prices is selected or entered, or purchase request information including the purchase request quantity is input and transmitted to the joint purchase server. (Been stored on the co-purchase server: SS ?) Steps (or means)

-This step (or means) is connected to the joint purchase server 16 through the purchase request terminal 12 used by each buyer, and then the joint purchase disclosure information on the sale products provided by the joint purchase server 16 If you check and select a specific product and want to purchase through the joint purchase, if you enter the purchase request information including the desired purchase request price and the quantity of the purchase request within the available time for purchase request, the corresponding purchase request information is the joint purchase server. It can be transmitted and stored to the (16) side.

At this time, each purchaser may directly input a desired purchase request price, and among the plurality of purchase request prices provided by the joint purchase server 16 as described in the example of FIG. 4 or 5 above. You can also select and enter either.

There are various selection input methods including inputting a purchase offer price number one by one or inputting by clicking a button associated with a provided purchase offer price number.

Selecting and inputting any one of them has been described in detail with reference to FIG. 4 or FIG. 5 as described above.

 And, if the purchase application quantity is one, even if you do not enter a separate purchase application quantity may be automatically processed to one purchase quantity. That is, for a specific purchase request quantity including the case where the purchase request quantity is 1, the purchase request quantity may be automatically inputted even if the purchase request quantity is not input separately.

In addition, each purchaser may operate to change the purchase request price that he / she applied for until the successful bid price is determined. As an example of how to change, you can change just by selecting a new purchase price, or you can cancel the previous purchase and make a new purchase with the new purchase price. If payment was made in advance at the time of application for purchase, additional payment or refund may be made according to the changed price payment rules.

Part of the purchase cost in which the purchase request price is reflected before the successful bid price is determined, including when the purchase request information is received from each purchase request terminal through the joint purchase server. Or to the total cost of purchase  Payment is accepted in advance (in consideration of variable costs). Step (or means) 3

-This step (or means) guarantees their purchase request by paying all or part of the purchase price according to the purchase request price and the quantity of the purchase request (in consideration of the variable cost) in advance when each buyer applies for a purchase. Step (or means).

If the buyer does not pay the purchase cost in advance before the successful bid price is decided (usually at the time of the purchase request), the purchase request can be canceled without any restrictions and damage to the seller. In case of cancellation, some amount is paid in advance in order to recover in the form of cancellation cancellation fee or to express a strong intention to purchase.

The purchase request status including the cumulative purchase request amount for each purchase request price for each purchase request price or for each purchase request price over the purchase request price through the joint purchase server includes the cumulative purchase request status for the purchase request price. Steps (or means) aggregated through

-In this step (or means), the co-purchase server 16 aggregates or purchases the purchase application status for each purchase request price for each purchase request price or the cumulative purchase request amount for each purchase request price that is greater than or equal to each purchase request price. to provide.

Here, the cumulative purchase application quantity for each purchase application price means a total quantity of all purchase application quantities requested for purchase at a price higher than the corresponding purchase application price.

For example, the joint purchase server 16 may provide a purchase request status including a cumulative purchase request quantity displayed in the "total" column of FIG. 5.

That is, the "accumulation" of FIG. 5 or FIG. 6 represents the cumulative purchase application quantity for each purchase application price that is requested for purchase above each purchase application price.

For each purchase offer price, the cumulative cumulative purchase order quantity purchased above the purchase offer price corresponds to an interval that is larger than the lower limit of the purchase order quantity interval condition (where the bid price may be determined at the purchase offer price). As the successful bid price is decided at the price (specific of the prices) below the lowest purchase price,

A purchaser who purchases at least one bid price (or more than one of the buyers) who has applied for a purchase price is determined to be a purchaser, and the purchaser can purchase at the same price as the bid price and purchase price below the bid price. Buyer (at least one of the buyers) who signed up for The result of the transaction, including the decision to be a failed buyer, is derived and the purchase request terminal (Or sales application terminal: SS ?) (Or means) provided or notified to the connected terminal, including

-This step (or means) is the stage (or means) that results from the conclusion of the transaction including the decision of the winning price at the end of the deadline for the joint purchase application and the division into a buyer who has not made a purchase and a buyer who has not made a purchase.

(Therefore, unlike a conventional joint purchase method, a buyer who has not been able to make a purchase may be generated even though a purchaser who has made a purchase exists even in a joint purchase.)

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

Of course, the part of the quantity of purchases applied for purchase by the recognized or relieved buyers by recognizing or relieving some or all of the buyers who failed to make purchases by the site administrator's discretion or seller's discretion or a separate remedy method Or they can buy the whole thing or provide some cost support.

A step (or means) of reimbursing the difference if the cost (purchased mainly from the desired price), which the buyer paid in advance at the time of the purchase application, is a step (or means), which will be explained later, is greater than the purchase cost reflecting the winning price. In this context, the refund amount may be calculated and then refunded more than the refund amount calculated at the site operator's discretion or the seller's discretion.

After a successful bid price is determined,

Through the co-purchase server,

The prepaid purchase cost (or more) received from the purchase application terminal used by the purchaser determined to be the non-purchaser is refunded (in consideration of the variable cost),

The prepaid payment exceeds the purchase cost that reflects the successful bid price among the prepaid purchase costs received from the purchase request terminal used by the purchaser determined as the concluded purchaser. Difference  A step (or means) in which costs (above) are refunded (in view of variable costs); Step 4-1 (or means)

-This step (or means) refunds all the purchase costs (above) paid in advance by the buyer who has not been determined to be a purchaser after the joint purchase server 16 ends (in consideration of variable costs), and makes a purchase. It is a step (or means) of refunding (in consideration of the variable cost) the prepaid cost (above) in excess of the purchase cost in which the winning price is reflected among the purchase costs prepaid by the concluded buyer.

In other words, the final selling price is determined by the successful bid price, and the buyer initially calculates the purchase cost reflecting his purchase request price and subtracts the purchase cost reflecting the successful bid price from the amount previously paid and refunds the rest.

 It's hardly possible, but at someone's discretion, you may be able to pay more than the rest. So the difference is that the cost of 'more than' will be refunded. In addition, the word "ideal" in the reimbursement of other expenses in other parts of the present application is the word used for the same intention.

In addition, since the present invention does not apply for a patent for a method of refunding a part of the amount paid by the card, that is, it is not a patent application related to electronic payment among patent fields related to electronic commerce, a problem to be solved in the present invention. I don't think so,

As for the refund of the amount prepaid with the card,

In other words, with the card, there are a few ways to refund the amount of money (over) to the buyer who prepaid the amount exceeding the purchase cost reflecting the winning price minus the purchase cost reflecting the winning price. The following (other methods are possible):

1. It will automate the cancellation of the (card) payment in advance and the payment of the purchase price reflecting the new winning price.

2. Charge your card bill in advance for a positive amount, and charge a different amount (= the amount you paid minus the purchase price that reflects the winning price), resulting in a winning price. It is arranged by paying the reflected purchase cost.

3. The card company remits the difference in expenses to the customer's account

4. The remitter transfers the amount previously paid to the customer's account by subtracting the purchase cost that reflects the winning price (the seller loses the card fee).

5. Earn points or credit cards at the card company by subtracting the purchase cost that reflects the winning price from the amount paid in advance. (It may be possible to make cash at any time.)

6. Earn points or cyber money on the operation site by subtracting the purchase price that reflects the winning price from the amount paid in advance (you can make it cashable at any time).

In the joint purchase method according to the present invention, the following step (or means) may be further added.

After a successful bid price is determined,

Through the co-purchase server,

The prepaid purchase cost (or more) received from the purchase application terminal used by the purchaser determined to be the non-purchaser is refunded (in consideration of the variable cost),

Prepayment of the purchase price received from the purchase request terminal used by the purchaser determined as the concluded purchaser is paid by the purchaser who made the purchase price (in consideration of the variable cost). The step (or means) accepted from the application terminal;

-This step (or means) means that the buyer pays for the shortfall if the amount paid in advance before the successful bid price is determined is less than the purchase price reflecting the successful bid price. Will be omitted.

If the cancellation of purchase from the purchase application terminal used by any of the buyers who have applied for purchase through the co-purchase server is accepted after the purchase is concluded as the purchaser, the purchase application is accepted from the purchase application terminal used by the buyer who cancels the purchase application. Step 4-2 (or means) in which part or all of the prepaid purchase costs are returned to the purchase cancellation penalty (in consideration of variable costs) and if the balance remains, the balance (or more) is refunded (in consideration of variable costs).

-If this step (or means) cancels the application for purchase after determining that the purchaser has made a purchase, it may cause damage to the seller. It is a step (or means) to recover the loss of the seller and guarantee the reliability of the transaction by returning it (in consideration of the variable cost) to the seller.

That is, from the seller's point of view, all the buyers who applied for a purchase purchased the product by lowering the selling price as much as possible by calculating the profits from the sales, in the judgment that all buyers who made the purchase were determined to purchase. If canceled, even after selling the product, the profits may be much reduced or even more damage than originally thought, and thus a predetermined penalty is given to the buyer who cancels the purchase application.

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

Step 1-1 in which payment for the sales deposit is accepted in advance (in consideration of variable costs) before a successful bid price is determined, including a point in time at which sales information is received (from a sales request terminal) through the joint purchase server. Or means).

-This step (or means) prepays the deposit from the seller in order to compensate for the loss of the concluded buyers, which may occur if the canceled buyer does not make a good sale even if the buyer concluded the purchase. In order to provide some or all of the pre-paid sales deposits (in consideration of variable costs) to buyers who have been accepted (mainly at the time of sales application) and the seller does not fulfill his obligations in the future, the reliability of the transaction This is to secure.

After the buyer concludes,

When the cancellation of sales is accepted from the sales application terminal used by the seller through the joint purchase server or the information that the seller has not fulfilled the obligation under the seller's right to be granted to the seller, the security deposit paid in advance (in consideration of the variable cost) ) Or

Refund the sales deposit (or more) to the seller (in consideration of variable costs) if the transaction is successful (or means).

-As described above, this step (or means) recovers the bid deposit prepaid by the seller in order to compensate for the loss of buyers who have concluded the purchase if the seller cancels the sale or fails to provide the goods for no good reason. Step (or means).

If the transaction is successful, 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 joint purchase server,

From the purchase request terminal used by a new buyer or a buyer who has not entered into a purchase, payment for the total purchase cost compared to the purchase cost reflecting the winning price (accepting the variable cost) is accepted.

The purchase cost reflecting the successful bid price is the prepaid purchase cost (accepting the variable cost) received from the purchase request terminal used by the buyer determined as a buyer who has not made a purchase due to the purchase request price below the bid price. Including payment for the insufficient purchase cost is accepted from the purchase application terminal used by the buyer determined to be a buyer who has not entered into the purchase (in consideration of variable costs).

The total purchase cost is settled Accept ,

A step (or means) further being given a chance to purchase a product at the winning price even for a buyer determined as a new buyer or a buyer who has not entered into a purchase;

-This step (or means) is a step (or means) in which the purchase price is lower than the winning price, and even a new buyer or a buyer who has not made a purchase is given more opportunity to purchase the product at the winning price. .

(If more opportunities are given,

-New buyers should pay the purchase cost reflecting the winning price.

An additional step (or means) is required to make additional payments for the amount insufficiently paid by the buyer, who is determined to have failed to make a purchase.

In other words, the amount prepaid by the buyer

If the bidder's bid price is less than the product multiplied by the number of purchase orders ordered at the time of purchase request,

The purchaser's prepaid amount is multiplied by the winning price multiplied by the quantity of the purchase order placed at the time of the purchase request.

Minus

Further steps (or means) for the buyer to pay additionally are needed.

(-Additional steps (or means) are required to pay the amount insufficiently paid by the buyer determined as the purchased buyer.

In other words, the amount prepaid by the buyer

If the winning price is less than the product multiplied by the quantity of purchases ordered at the time of purchase request,

The amount paid by the buyer in advance is equal to the winning price multiplied by the quantity of the purchase application ordered at the time of purchase.

Minus

Further steps (or means) for the buyer to pay additionally are needed.

if not,

After the payment has been canceled automatically or manually, the entire purchase price reflecting the winning price may be settled again.

 Alternatively, this step (or means) may be automatically selected at the time of inputting the purchase application information.

Automatically causing this step (or means) to happen here includes having the amount settled automatically or the entire purchase price settled.)

A step (or means) of providing an information exchange means including a message and a comment for allowing information exchange about an appropriate successful bid price to be made between terminals including a purchase request terminal or a sales request terminal through the joint purchase server;

-This step (or means) is a step (or means) to enable the information exchange including the prediction, discussion of reasonable winning price by means including comments, notes, bulletin boards to facilitate communication between sellers or buyers. )to be.

This is to enable sufficient information on the prediction of a successful bid sale price, so that the buyer who fails to purchase as a result of applying for a purchase price that is too low due to lack of information is required. Minimize the number.

So far, the facts have been described as concepts that may belong to embodiments of the concepts claimed herein to facilitate understanding of the broad concepts herein.

We will now discuss the comprehensive concepts herein.

The joint purchase disclosure information to which the comprehensive concept of the present application is applied includes that the more the purchase application quantity increases, the more benefits are provided to the buyer. These benefits include no benefits at all. This is because it may not provide benefits under a certain amount of purchase application.

Up to now, the method of the present application has been described with only the benefit of lowering the price. That is, as illustrated in FIG. 4, FIG. 5, or FIG. 6, only when there is a joint purchase announcement of the seller that the price is lowered as the purchase application quantity increases.

For buyers, the benefits are not just lower prices.

In addition to lower prices as the volume of purchases increases,

As the volume of purchases increases, the condition that a variety of commodities (= goods or services) are added to the buyer (including changes to more valuable goods) in addition to the basic goods is also a benefit from the buyer's position.

Even if the quantity of purchases is increased, the price remains the same, but as the quantity of purchases is increased, various products (= goods or services) in addition to the basic goods are added to the buyer (including changes to more valuable goods). The condition is also a benefit from the buyer position. If the price is the same, it includes a free case.

As above, with the price still in place (or just a little lower), if a product is added to the buyer (including a change to a more valuable product), then the buyer's position adds a value of the product (to a more valuable product). In the event of a seller's position, the buyer only needs to spend a small amount more than converting any value received by the buyer into an amount.

For example, it is often more profitable for the seller to leave the price at 10,000 won and give it more than 4,000 won rather than selling the 10,000 won meat at 6,000 won. Because the cost of the additional 4,000 won worth of meat may be only 1,000 won, it is 3,000 won more profitable than sellers selling 4,000 won off. At the same time, many buyers will be satisfied.

As the volume of purchases increases, there is a wide variety of products supplied to buyers, with the addition of any product (including a change to a more valuable product) in addition to the basic product. It is up to the seller to decide. For example, the following product may be additionally given.

Gift certificate (e.g., 10,000 won, 50,000 won, 100,000 won), cash refund (e.g., 10,000, 50,000, 100,000 won), service time (e.g., 10 minutes, 30 minutes, 1 hour), service period (e.g. 1 Month, 6 months, 1 year), discount rate (e.g. 10%, 30%, 50%), exemption of specific amount (e.g. 10,000 won exemption of 30,000 won, 20,000 won exemption of 30,000 won, 3 out of 30,000 won) 10,000 won exemption), merchandise (e.g. cell phone rings, stylus pens, LCD protective film), merchandise (e.g. drinks, tea, wine), etc.

If the additional item is a "cash refund", it means that the seller can give cash to the buyer.

4 and 5 are charts showing the results of the joint purchase disclosure and purchase request, in which the price decreases as the purchase application quantity increases for the stake A having a normal price of 10,000 won.

However, as shown in FIG. 10, even if the quantity of purchases is increased, the price does not change, and as the quantity of purchases is increased, certain products are added to the buyer (or changed into more valuable products) to be supplied. (To reduce the number of drawings, the co-purchase disclosure information and results are presented together.)

10 will be described below.

Even if the purchase volume increases, the price is the same as 10,000 won. However, as the purchase volume increases,

In the second section (purchase request quantity), only additional drinks are supplied.

In the third section (purchase request volume), additional drinks and tea will be provided.

Section 4 (Quantity of Purchase) indicates that additional beverages, tea and wine are available.

(if not,

In the second section (purchase request quantity), only additional drinks are supplied.

In the third section (purchase request quantity), only the car is additionally supplied,

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

In the table where additional supplies are displayed

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

In the second section (purchase request quantity), only additional drinks are supplied.

In the third section (purchase request volume), additional drinks and tea will be provided.

In section 4 (purchase request volume), the interpretation of the additional supply of beverages, tea and wine will be referred to as the cumulative benefit method in the method of applying additional benefits.

In the second section (purchase request quantity), only additional drinks are supplied.

In the third section (purchase request quantity), only the car is additionally supplied,

In Section 4 (Quantity of Purchase Application), the interpretation that only additional wine is supplied will be referred to as the 'Individual Benefits Method' in the Additional Benefits Method.

As shown in FIG. 11, if the additional supply goods are marked with overlapping benefits in the purchase application benefit column corresponding to each purchase quantity section, there will be no confusion even if there is no notice about the interpretation of the chart.

(Double benefits of adding beverages are marked in sections 2 and 3 of FIG. 11, and overlapping benefits of adding beverages and tea are marked in sections 3 and 4.)

As shown in Fig. 11, unless there is a specific condition, it may be interpreted as follows.

In the second section (purchase request quantity), only additional drinks are supplied.

In section 3 (purchase request), only drinks and tea are additionally supplied.

In the 4th section (purchase volume), additional drinks, tea and wine will be supplied.)

Here, we will continue with the assumption that, when a joint purchase announcement is made as shown in Fig. 10, it is assumed that additional supplies will be constructed as shown in Fig. 11.

Looking at the result portion of Figure 10, it can be seen that the total number of purchase application is 490, the purchase application benefits corresponding to section 3 has been successful by the same principle as the explanation principle related to FIG. In other words, if the winning offer is priced at 10,000 won and the co-purchase disclosure information states that the additional benefit is applied as a "cumulative benefit application method," the additional product will be a drink and a tea. If the co-purchasing disclosure informs you that the method of applying additional benefits applies as an "individual benefit application method," the rules for supplying additional cars may apply.)

In addition, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section at the time of the purchase request is purchased under the condition of benefit corresponding to the third (purchase request quantity) section. The purchaser who makes a purchase request while selecting a purchase application benefit corresponding to section 4 (Quantity of Purchase Request) when making a purchase request is not concluded. This purchase execution principle is described in detail in the description related to FIG.

But again, a little more detail:

Looking at the result portion of Figure 10, the total purchase amount is 490,

If you look at the status of your purchase request, once you have announced in the co-purchase disclosure that you apply the additional benefit as a "cumulative benefit method",

The number of purchase applications for which the purchase application benefits are selected without additional products at 10,000 won is 40, the total is 40,

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

The number of purchase requests for which purchases and drinks are added to the amount of 10,000 won is 180, the total amount is 350,

The number of purchase requests for the purchase application benefit, which includes beverages, tea and wine at 10,000 won, is 140, and the total is 490.

(If the co-purchase disclosure information states that the method of applying additional benefits is applied as an "individual benefit application method,"

The number of purchase applications for which the purchase application benefits are selected without additional products at 10,000 won is 40, the total is 40,

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

The number of purchase requests for which the car is an additional product for 10,000 won is 180, the total is 350,

The number of purchase applications for which wine is added as an additional product for 10,000 won is 140, and the total is 490.)

Since the lower limit of the condition of purchase application quantity section of section 1,2,3 is smaller than the cumulative amount of purchase application quantity, section "satisfaction" of section 1,2,3 is "satisfaction". Among the purchase application benefits corresponding to the purchase application quantity section in which the "satisfaction" column is "satisfaction", the purchase application benefit price of section 3, which is the best purchase application benefit, is 10,000 won, and an additional benefit application method is called "cumulative benefit application method." If the joint purchase disclosure notice is applied, the purchase application benefit, in which the drink and the tea are additional products, is successful, and the purchase application benefit is selected by selecting the purchase application benefit in the 1st, 2nd, or 3rd section, that is, the purchase The 350, the cumulative number of purchase requests made by the concluded buyers, will be supplied with additional drinks and teas at a price of 10,000 won.

(If, according to Seller, the Notice of Co-Purchase Disclosure states that the Supplemental Benefits Method applies as the "Individual Benefits Method", the additional product will only be a car.)

Since the lower limit (500) of the purchase application quantity section of the 4th section is larger than the cumulative total of the purchase application quantity (490), the section 4 is satisfied because the "satisfaction" section of section 4 is "satisfied". The purchase offer benefits under the conditions are not successful, and the product cannot be supplied with the purchase request benefits for 10,000 won and additional drinks, tea and wine. So, if you apply for a purchase by paying 10,000 won in advance at the time of applying for purchase and selecting additional products, you can choose 10,000 for each buyer who has not entered into a purchase because you have selected the purchase application benefit of the 4th section. Refund each one won.

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

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

12 illustrates selling an oven.

As shown in FIG. 12, although the purchase application quantity increases as shown in FIG. 10, the price remains unchanged to 500,000 won, and as the purchase application quantity increases, more products are supplied (including changes to more valuable products). .

In the result portion of Figure 12, the total number of purchases is 490,

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

If the co-disclosure notice informs you that the method of applying additional benefits is the "cumulative benefit method", then the additional product will be scales and frying pans. "If you are notified in the co-purchase disclosure that it applies to you, you may also apply the rules for supplying additional frying pans only.)

In the case of a purchase application, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section shall apply to the purchase application benefit condition corresponding to the third (purchase request quantity) section. The purchaser who made a purchase request while selecting a purchase application benefit corresponding to section 4 (Quantity of Purchase Request) at the time of the purchase request is not made. This purchase execution principle is described in detail in the description of FIG. 5 or FIG. 10.

Now let's look at an example where the price is free, but as the volume of purchases increases, more products are added (including changes to more valuable products).

This is mainly the case that can be used for service contracts, such as internet subscriptions, insurance products. Subscriptions to these services do not incur costs at the time of subscription, but can be applied to products that incur fixed costs at regular intervals (eg every month).

For example, the following describes an internet subscription product.

Among the products of the Internet supply company called KT, there are high-speed Internet products that require payment of 30,000 won per month. However, if you sign up for a commitment to continue using for more than three years, you only pay 25,000 won a month. For buyers, no fee is required in most cases for the subscription fee (co-purchase announcements may be made in advance to pay for the first month's charges, but this example assumes that they do not).

Figure 13 is an example showing the joint purchase announcement and results for KT, high-speed Internet, 25,000 won per month, three-year commitment product subscription.

Even if the purchase application quantity increases as shown in FIG. 10, the price remains unchanged (to 0 won (= free)), and as the purchase application quantity increases, more products are supplied (including changes to more valuable products). .

13, the total purchase volume is 490,

By the same principle as in FIG. 5 or FIG. 10, it can be seen that the purchase application benefit corresponding to section 3 has been successful. In other words, if the price of a successful bid is 0 won (= free) and the additional purchase method is applied as a "cumulative benefit application method", the additional purchase product will be a mouse and an MP3. (Depending on the seller, the rule of supplying additional MP3s may apply if the co-disclosure disclosure informs you that the additional benefit applies as a "individual benefit method.") In the meantime, buyers who have signed a purchase pay 25,000 won a month.

In addition, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section at the time of the purchase request is purchased under the condition of benefit corresponding to the third (purchase request quantity) section. The purchaser who makes a purchase request while selecting a purchase application benefit corresponding to section 4 (Quantity of Purchase Request) when making a purchase request is not concluded. This purchase execution principle is described in detail in the description of FIG. 5 or FIG. 10.

And let's see if the benefit is cash.

The fact that the seller provides the cash benefits to the buyer is that the seller gives the buyer cash.

Figure 19 is an example showing the joint purchase disclosure and results for KT, high-speed Internet, 25,000 won per month, three-year commitment subscription.

Even though the purchase application quantity increases as shown in FIG. 10, the price remains unchanged (to 0 won (= free)), and as the purchase application quantity increases, more and more products are supplied (including changes to more valuable products). .

Looking at the result portion of Figure 19, the total purchase application number was 490,

By the same principle as in FIG. 5 or FIG. 10, it can be seen that a purchase application benefit corresponding to section 3 has been successful. In other words, if the price of a successful bid is 0 won (= free) and the additional purchase method is applied as a "cumulative benefit application method," the joint purchase disclosure information indicates that the additional cash is 60,000 won (10,000 won + 2 10,000 won + 30,000 won will be deposited to the buyer (depending on the seller, if the co-purchasing disclosure informs you that the additional benefit is applied as a "individual benefit application method", the additional rules of 30,000 won will be applied. May be). In the meantime, buyers who have signed a purchase pay 25,000 won a month.

In the case of a purchase application, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section shall apply to the purchase application benefit condition corresponding to the third (purchase request quantity) section. The purchaser who applies for purchase while selecting the benefit corresponding to section 4 (Quantity of Purchase Application) at the time of purchase application is not entered into the purchase. This purchase execution principle is described in detail in the description of FIG. 5 or FIG. 10.

In addition, let's look at the case where the purchase application quantity unit is the amount.

For example, as shown in FIG. 14, a bakery would like to promote a joint purchase for some breads of a certain kind.

When purchasing several kinds of bread (or one kind or not all kinds) that are subject to a joint purchase at the price at which the buyer visits and purchases, As the purchase application amount is increased, the discount rate may correspond to the price discount rate at the time of the visitor's visit and purchase. )

In this case, when the purchaser makes a purchase request, he or she expresses his intention to purchase some bread.

Thus, looking at the results of applying for purchase (of many buyers) of Fig. 14,

Since the purchase application quantity unit is 10,000 won, the total purchase application quantity is 4.9 million won, and it can be seen that the purchase application benefit corresponding to section 3 has been successful by the same principle as in FIG. 5 or FIG. 10. In other words, the winning offer means that if the co-purchase disclosure information states that the additional benefit application method is applied as a "cumulative benefit application method", the amount of bread that each buyer who has passed the purchase application has made an intention to purchase while making a purchase request Will be available at a discount of 45% (= 0% + 15% + 30%). For example, a rule may be applied that can only be purchased at a 30% discount).

In the case of a purchase application, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section shall apply to the purchase application benefit condition corresponding to the third (purchase request quantity) section. The purchaser who made a purchase request while selecting a purchase application benefit corresponding to section 4 (Quantity of Purchase Request) at the time of the purchase request is not made. This purchase execution principle is described in detail in the description of FIG. 5 or FIG. 10.

Since each buyer who makes a purchase is entitled to a discounted percentage of the winning price, he or she can actually purchase bread for the amount he or she has applied for.

Before the successful bid is decided, even if the payment is made in advance based on the price at the time of the joint purchase disclosure, the refund may not occur.

After the winning bid is decided, if the buyer purchases on the basis of the price at the time of purchase, the payment may not be made in advance, and therefore, no refund may occur.

This approach may be better suited for products with shorter periods of fluctuation in price and margins. Car gasoline, for example.

An example will be described with reference to FIG.

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

For example, as shown in Fig. 15, some gas stations are going to promote the joint purchase of some kinds of oils.

The quantity of purchase application that is requested to be purchased for joint purchase in order to purchase some kinds of oil (or one kind or not all kinds) which are the subjects of the joint purchase at the price at which the buyer visits and purchases (= As the purchase application amount is increased, the discount rate may correspond to the discount rate at the time of the visitor's visit and purchase. (The price may be the price at the time of the joint purchase announcement, not the price at the purchaser's visit and purchase.) )

In this case, when the buyer makes an application for purchase, he / she expresses his intention to purchase some oil and then applies for the purchase.

Thus, looking at the results of applying for purchase (of many buyers) in Fig. 15,

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

In other words, if the successful bid is informed in the joint purchase disclosure information that the additional benefit is applied as a "cumulative benefit application method", each buyer who has passed the purchase application will apply for the amount of gasoline that he or she intends to purchase. Will be available at a discount of 3% (= 0% + 1% + 2%) (depending on the seller, if the co-disclosure disclosure information states that the additional benefit applies as a "individual benefit method") For example, a rule may be applied to purchase a discount of 2%).

In the case of a purchase application, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section shall apply to the purchase application benefit condition corresponding to the third (purchase request quantity) section. The purchaser who made a purchase request while selecting a purchase application benefit corresponding to section 4 (Quantity of Purchase Request) at the time of the purchase request is not made. This purchase execution principle is described in detail in the description of FIG. 5 or FIG. 10.

The condition is that each buyer who makes a purchase can purchase the oil as much as the amount he applied for at a discounted price corresponding to the winning bid.

Before the successful bid is decided, even if the payment is made in advance based on the price at the time of the joint purchase disclosure, the refund may not occur.

After the winning bid is decided, if the buyer purchases on the basis of the price at the time of purchase, the payment may not be made in advance, and therefore, no refund may occur.

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

16, an example will be described.

Since the purchase application quantity unit is liters, the total purchase application quantity is 490 liters, and it can be seen that the purchase application benefit corresponding to section 3 has been won by the same principle as in FIG. 5 or FIG. 10. In other words, the winning offer is the volume of each buyer who has passed the purchase offer and has made an intention to make a purchase if the joint purchase announcement has announced that the additional benefit is applied as a "cumulative benefit application method." You will be able to purchase as much gasoline as 3% (= 0% + 1% + 2%). (Depending on the seller, the additional benefit is applied as a "individual benefit method." If notified in the disclosure, rules may be applied for a 2% discount).

In the case of a purchase application, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section shall apply to the purchase application benefit condition corresponding to the third (purchase request quantity) section. The purchaser who made a purchase request while selecting a purchase application benefit corresponding to section 4 (Quantity of Purchase Request) at the time of the purchase request is not made. This purchase execution principle is described in detail in the description of FIG. 5 or FIG. 10.

This is a condition in which each purchaser can actually purchase the volume of gasoline he or she has applied for at a discounted percentage of liters, which is a discounted benefit.

If you make a payment in advance of a winning offer, the price per liter of the discounted percentage that you applied for is multiplied by the volume you applied for, and the price per liter of the discounted percentage of the winning offer is multiplied by the volume applied for. The difference will be refunded.

If you make a prepayment for the amount of money you have applied for, based on the price at the time of the joint purchase announcement, before the successful bid price is determined, a discount equal to the winning price at the price per liter of the discounted percentage that you have applied for The difference, minus the price per liter, will be refunded (refer to the refund column in Figure 16-assuming the price per liter is 100 won without discount),

After the successful bid benefits are determined, if the buyer purchases on the basis of the price at the time of purchase, the payment may not be made in advance, and therefore, no refund may occur (not shown).

Now let's look at an example where the extra benefits include extended periods of time.

When purchasing a 6-month aerobic cooperative products, there may be a joint purchase announcement and results as shown in FIG.

Referring to the result portion of FIG. 17, it can be seen that the total purchase application quantity has been 490, and the purchase application benefit corresponding to section 3 has been won by the same principle as in FIG. 5 or FIG. 10. In other words, if the price of the winning bid is 300,000 won and the joint purchase disclosure information indicates that the additional benefit is applied as a "cumulative benefit application method," the additional product will be extended for one month, two months, and total. It will be extended for three months. In other words, the basic six-month course ticket is extended for three months (= none + one month + two months), so that the class can be taught for nine months. If the co-purchase disclosure notes that it applies, then the rule of supplying an additional two-month extension may apply.)

And so far, as the number of purchase applications increases

There is no product added, but only the price is lowered

The price does not change, but only the benefits of cumulative additions or changes to more valuable commodities.

As the price is lowered as shown in FIG. 18, additional products may be accumulated or replaced with more valuable products.

18 is an example of a joint purchase announcement and its result for a mobile phone subscription product.

It is assumed that a product is contracted to use a service that requires a payment of 50,000 won a month as a basic rate while transferring a mobile phone service company to a specific carrier while purchasing a specific mobile phone.

In section 1 of the application for purchase, you will have to pay 300,000 won for the mobile phone (because it is a free phone if you have an old phone, but you can use it for free if you have an old one). If you have it, it costs about 700,000 won for the specific phone.)

When the change from section 1 to section 2, the price of mobile phones does not change, but additional mobile phone rings worth 10,000 won are supplied.

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

When changing from section 3 to section 4, the price of mobile phone is lowered by 10,000 won.

In the result portion of Figure 18, the total number of purchases was 490,

By the same principle as in FIG. 5 or FIG. 10, it can be seen that a purchase application benefit corresponding to section 3 has been successful. In other words, if the price of a successful bid is 290,000 won for mobile phones, and the additional purchase method is applied as a "cumulative benefit application method", the additional purchase product is provided with a mobile phone ring worth 20,000 won and 2 It is a stylus pen worth 10,000 won. (If the seller has announced in the joint purchase announcement that the additional benefit is applied as a "individual benefit application method," the mobile phone price is 290,000 won and only 20,000 won worth of stylus pen is added. Rules may be applied). In addition, the purchaser who signed the purchase is subscribed to a service that uses the rate plan of 50,000 won per month for two years.

Now, let's take a look at a combination of benefits added or changed as the number of purchase requests increases. Various benefits may be combined, including the addition or modification of cash, gift certificates, discount rates, or general industrial products, but in the following examples, additional amounts of cash and general industrial products are added as the quantity of purchases increases. It will be described an embodiment to be supplied).

Figure 20 is an example showing the joint purchase announcement and results for KT, high-speed Internet, 25,000 won per month, three-year commitment subscription (refer to the description related to Figure 13 for a detailed description of the product).

Even if the purchase application quantity is increased as shown in FIG. 10, the price is 0 won (= free), and as the purchase application quantity is increased, the products supplied are added (including being changed into more valuable products).

Looking at the result portion of Figure 20, the total number of purchases was 490,

By the same principle as in FIG. 5 or FIG. 10, it can be seen that a benefit corresponding to section 3 has been successful. In other words, if the price of a successful bid is 0 won (= free) and the additional purchase method is applied as a "cumulative benefit application method," the joint purchase disclosure information indicates that the additional cash is 60,000 won (10,000 won + 2 10,000 won + 30,000 won) and 10,000 won worth of mouse and 50,000 won worth of MP3 will be supplied to the buyer (depending on the seller, if the co-purchase disclosure information indicates that the additional benefit is applied as an "individual benefit application method"). In addition, the rule may supply additional cash of 30,000 won and MP3 (equivalent to 50,000 won). In the meantime, buyers who have signed a purchase pay 25,000 won a month.

In the case of a purchase application, the purchaser who applies for purchase while selecting the purchase application benefit corresponding to 1, 2, or 3 (purchase request quantity) section shall apply to the purchase application benefit condition corresponding to the third (purchase request quantity) section. The purchaser who made a purchase request while selecting a purchase application benefit corresponding to section 4 (Quantity of Purchase Request) at the time of the purchase request is not made. This purchase execution principle is described in detail in the description of FIG. 5 or FIG. 10.

10 to 21, the description of the benefits were explained by dividing the elements of the benefits by the purchase application price (or the discount rate) and the additional supply products so that the description of the benefits can be easily understood. The purchase offer price is an amount that may be enforced by the buyer to make a mandatory payment at the time of application for purchase as a condition of fulfilling the obligation of the seller after the purchase is concluded, and the additional supply goods are to be fulfilled by the seller. I just let go. Since the discount rate may be the discount rate for the amount that the buyer should deposit at the time of application for purchase, or the amount that the buyer may be discounted when receiving the actual goods, the discount rate should be written in the column indicating what the buyer should fulfill. It may be efficient, or it may be more efficient if it is listed in the column that the seller is required to fulfill.

Anyway, the benefits factor,

With a clear description of benefits, including a clear understanding of what buyers need to do and what sellers need to do,

The same column may be written all at once, or the marker may be divided arbitrarily. In the case of division, it may be divided into two or more factors including dividing into two factors, a purchase offer price (or a discount rate) and an additional supply product.

Now let's synthesize what we are looking for comprehensively here.

Detailed description of each step (or means) below will be omitted. This is because the key points of the following techniques are described in great detail in the description of FIG. 5 in a transaction where only a price can be reduced as the purchase application quantity increases. Differences are not important and can be understood by reasoning from the preceding description.

And the process of prepaying and refunding the purchase cost, the process of paying and refunding the purchase deposit, and the process of paying and refunding the sales deposit.

As described in the transaction where only the price can be reduced as the purchase volume increases, the technique not described below may be applied. Since it has been described in detail in the description related to Figure 5, the application method will not be described separately.

In the following description of claims, "purchasing price" has been replaced by the words "purchasing application benefits" in the description of how the price of benefits can only be reduced as the quantity of purchases increases. The meaning of "applied price" means "purchase application benefits below", and "less than purchase price" has been replaced by "excess purchase application benefits". This is because the purchase offer price and purchase offer benefits are inversely proportional to each other. For example, the higher the purchase application price, the lower the purchase application benefit, and the lower the purchase application price, the higher the purchase application benefit.

The explanation of the other changes can be easily seen by referring to the description of how to obtain a benefit of lowering the price only as the quantity of purchases increases.

An electronic commerce system (or a purchase request terminal available to one or more buyers), in which a joint purchase server and a purchase request terminal usable by one or more buyers can be connected to each other via a network communication network including the Internet. In the joint purchase method using an electronic commerce system that can be connected to each other through the network communication network including the Internet and the sales application terminal available to the seller,

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

(Step (or means) of the joint purchase announcement information including the purchase request benefits corresponding to the two or more purchase request quantity section for the transaction target product to the joint purchase server;)

-This step (or means) is a site where the seller provides the co-purchasing conditions to the site operator including the different purchase application benefits corresponding to two or more different purchase application quantity sections for a specific product as shown in FIG. A step (or means) entered by an operator or directly by a seller.

It is obvious that different purchase offer prices do not correspond to the different purchase request quantities in the joint purchase announcement, and that even if a specific discount rate corresponds to different normal prices, different purchase request prices are considered to correspond. It belongs to the scope of rights. This is because applying a discount rate to the usual price results in a discounted price.

In principle, benefits must have two or more conditions that are comparable to each other. However, in this application, the benefits to be fulfilled by the buyer and the seller itself according to each purchase application quantity section can be referred to as benefits.

Further, in this step, a narrower range of steps may be generated by adding a limited phrase , such that ' even if the purchase application quantity section is changed, the price does not change or there is an extremely minimal section .

(Prices will not change even if the purchase volume is changed. No change  So that there is very little price fluctuation,

(B) transmitting joint purchase disclosure information (or means) to the joint purchase server including purchase application benefits corresponding to two or more purchase application quantity sections for a transaction target product;

The deformation step corresponds to the purchase application quantity section as shown in FIG. 10, 11, 12, 18, 19, or 20 It is a step (or means) that there is no change in price or extremely low price change even if the quantity of purchase application benefits is changed among the contents of the purchase application benefit condition. Since only additional products are changed as they are changed, the price may not be a selection factor for the purchase application benefits for the buyer.

Paid products are also useful, but they are free from the outset, such as insurance, internet subscription, and cell phone subscription, which will be more useful for products that only require a contract, and can be more profitable to the seller in terms of margin. .

The following steps (or means) are described in all cases, regardless of whether or not there is a change in price. Refer to the steps described below for the subsequent steps (or means) in the state where the purchase request benefit is corresponding to each purchase request quantity section.

Through the joint purchase server, the joint purchase disclosure information including the purchase application benefits corresponding to the two or more purchase application quantity sections for the transaction target product is the purchase request terminal (Or sales application terminal: SS ?) To connected terminal including Accepted  Step (or means);

-This step (or means) refers to the co-purchasing conditions, including the fact that different purchase application benefits correspond to two or more different purchase application quantity sections for a specific product as shown in Fig. 10 (~ 20). It is a step (or means) provided to the operator so that the joint purchase disclosure information entered by the site administrator or directly entered by the seller can be displayed on the purchase request terminal.

 When a specific discount rate is applied to two or more purchase application quantity sections, it is recommended to have a different discount rate for each purchase application quantity section. However, even if it is a different section, joint purchase may be performed so that the same discount rate is applied if necessary.

In addition, the specific discount rate may be 0%. That is, there may be a purchase application quantity section to which the price is normally applied.

In this step, a more specific step (or means) may be created by adding a limited phrase , such that ' even if the purchase application quantity section is changed , there is no price change or a section having a very small price fluctuation '. .

Even if the quantity of purchase application is changed, the price No change  So that there is very little price fluctuation,

Through the joint purchase server, the joint purchase disclosure information including the purchase application benefits corresponding to the two or more purchase application quantity sections for the transaction target product is the purchase request terminal (Or sales application terminal: SS ?) To connected terminal including Accepted  Step (or means);

The deformation step corresponds to the purchase application quantity section as shown in FIG. 10, 11, 12, 18, 19, or 20 It is a step (or means) that there is no change in price or extremely low price change even if the quantity of purchase application benefits is changed among the contents of the purchase application benefit condition. Since only additional products are changed as they are changed, the price may not be a selection factor for the purchase application benefits for the buyer.

Paid products are also useful, but they are free from the outset, such as insurance, internet subscription, and cell phone subscription, which will be more useful for products that only require a contract, and can be more profitable to the seller in terms of margin. .

For sellers, it is often more profitable to supply additional buyers with the same amount of goods (or even more) that they wanted to lower rather than lower. This is because the cost of additional goods is less than the price of goods supplied anyway. If the additional product was originally handled by a seller who requested the joint purchase, the cost would be even lower.

Even if the additional product was a product that was not handled by the seller who requested the joint purchase, the cost purchased by the seller would be lower due to the large quantity of the joint purchase.

The following steps (or means) are described in all cases, regardless of whether or not there is a change in price. Refer to the steps described below for the subsequent steps (or means) in the state where the purchase request benefit is corresponding to each purchase request quantity section.

Purchase request information of any one or more of the two or more purchase request benefits is selected from the purchase request terminal used by each buyer, or purchase request information including the purchase request quantity is input and transmitted to the joint purchase server. (Been stored on the co-purchase server: SS ?) Becoming (or means);

-This step (or means) is connected to the joint purchase server 16 through the purchase request terminal 12 used by each buyer, and then the joint purchase disclosure information on the sale products provided by the joint purchase server 16 If you want to make a purchase through joint purchase by selecting a specific product, select the purchase application benefit that includes your desired purchase application price within the available time of purchase application, and enter the purchase application information for the purchase application quantity. Purchase application information may be transmitted to the joint purchase server 16 side and stored.

At this time, each buyer may directly enter the desired purchase application benefits, a plurality of purchase application benefits provided by the joint purchase server 16, as described in the example illustrated in Figure 10 (~ 20) above. Any one of these may be selected and input.

There are a variety of selection input methods including inputting a purchase request benefit letter one by one or inputting by clicking a button related to the provided purchase offer benefit letter.

Selecting and inputting any one of them has been described in detail with reference to FIG. 4 or FIG. 5 as described above.

 And, if the purchase application quantity is one, even if you do not enter a separate purchase application quantity may be automatically processed to one purchase quantity. That is, for a specific purchase request quantity including the case where the purchase request quantity is 1, the purchase request quantity may be automatically inputted even if the purchase request quantity is not input separately.

In addition, each purchaser may operate so as to change the purchase application benefit that he / she purchases until the successful bid benefit is determined. As an example of how to change, you can change just by selecting a new purchase offer, or you can cancel the previous purchase and apply for a new purchase. If payment was made in advance at the time of application for purchase, additional payment or refund may be made according to the changed price payment rules.

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

Part of the purchase cost reflecting the purchase request price before the successful bid is determined, including the time when the purchase request information is received from each purchase request terminal through the joint purchase server. Or to the total cost of purchase  The stage (or means) in which payment for the payment is accepted in advance.

-In this step (or means), each purchaser pays in advance (in consideration of variable benefits) all or part of the purchase price according to the purchase request price and the quantity of the purchase application that are reflected in the purchase application benefits applied for by the purchaser. It is a step (or means) to guarantee their purchase application.

If the buyer does not pay the purchase cost in advance before the winning bid is decided (usually at the time of the purchase application), the purchase application can be canceled without any restrictions and damage to the seller later. In case of cancellation, some amount is paid in advance in order to recover in the form of cancellation cancellation fee or to express a strong intention to purchase.

The purchase request status including the amount of purchase application for each purchase application benefit or the cumulative purchase application amount for each purchase application benefit for each purchase application benefit less than the purchase application benefit for each purchase application benefit is obtained through the joint purchase server. Aggregated through (or means);

-In this step (or means), the joint purchase server 16 aggregates or purchases the purchase application status for each purchase request benefit or the cumulative purchase request amount for each purchase request benefit less than each purchase request benefit. 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 benefits equal to or worse than the purchase application benefits from the buyer's point of view.

For example, the joint purchase server 16 may provide a purchase request status including a cumulative purchase request quantity displayed in the "accumulation" column of FIG. 10 (~ 20).

That is, the "accumulation" of FIG. 10 (~ 20) represents the cumulative purchase application quantity for each purchase application benefit that is purchased under each purchase application benefit.

After the joint purchase application, through the joint purchase server,

For each purchase application benefit, the cumulative purchase application quantity purchased with the purchase application benefit that is less than or equal to the purchase application benefit is greater than or equal to the best purchase application benefit among the purchase application benefits that correspond to a section larger than the lower limit of the condition of the purchase application quantity section. As the benefit is determined by the winning bid,

A buyer who has applied for a purchase under the winning bid benefit (at least one of the buyers) is determined to be a buyer who has made a purchase, and the buyer can purchase the product while receiving the same benefit of the above bid. Deriving (or means) a result of the transaction, which includes determining that a buyer (at least one of the buyers) who has been purchased with excess purchase application benefits is a buyer who has not entered into a purchase;

-This step (or means) is the step (or means) that results from the conclusion of the transaction including the decision to win the bid upon termination of the joint purchase application period and divided into the buyer who has made a purchase and the buyer who has not made a purchase.

(Therefore, unlike the conventional joint purchase method, even in the joint purchase, a buyer determined as a buyer who has not made a purchase even though there is a purchaser who has made a purchase may be generated.)

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

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

Of course, the part of the quantity of purchases applied for purchase by the recognized or relieved buyers by recognizing or relieving some or all of the buyers who failed to make purchases by the site administrator's discretion or seller's discretion or a separate remedy method Or they can buy the whole thing or provide some cost support.

A step (or means) of reimbursing the difference if the cost (purchased mainly from the desired price), which the buyer paid in advance at the time of the purchase application, is a step (or means), which will be explained later, is greater than the purchase cost reflecting the winning price. In this context, the refund amount may be calculated and then refunded more than the refund amount calculated at the site operator's discretion or the seller's discretion.

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

After the winning bid is decided,

Through the co-purchase server,

The prepaid purchase costs (above) received from the purchase application terminal used by the purchaser determined as the unsuccessful purchaser are refunded (in consideration of the variable benefits),

The pre-payment of the pre-paid purchase costs received from the purchase application terminal used by the purchaser determined as the concluded purchaser exceeds the purchase cost reflecting the winning bid. Difference  The cost (or more) being refunded (in view of the variable benefits) (or means);

-This step (or means), the co-purchase server 16 refunds the purchase cost (in consideration of the variable benefits) pre-paid by the buyer determined as a buyer who has not made a purchase after the end of the joint purchase, and the buyer who made the purchase in advance 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 buyer initially calculates the purchase cost reflecting his / her purchase request price and subtracts the purchase cost reflecting the successful bid price from the amount paid in advance and the rest (in consideration of variable benefits). ) Will be refunded.

 It's hardly possible, but it could be more than just the rest. So the difference is that the cost of 'more than' will be refunded. In addition, the word "ideal" in the reimbursement of other expenses in other parts of the present application is the word used for the same intention.

In addition, since the present invention does not apply for a patent for a method of refunding a part of the amount paid by the card, that is, it is not a patent application related to electronic payment among patent fields related to electronic commerce, a problem to be solved in the present invention. I don't think so,

As for the refund of the amount prepaid with the card,

In other words, with the card, there are a few ways to refund the amount of money (over) to the buyer who prepaid the amount exceeding the purchase cost reflecting the winning price minus the purchase cost reflecting the winning price. The following (other methods are possible):

1. It will automate the cancellation of the (card) payment in advance and the payment of the purchase price reflecting the new winning price.

2. Charge your card bill in advance for a positive amount, and charge a different amount (= the amount you paid minus the purchase price that reflects the winning price), resulting in a winning price. It is arranged by paying the reflected purchase cost.

3. The card company remits the difference in expenses to the customer's account

4. The remitter transfers the amount previously paid to the customer's account by subtracting the purchase cost that reflects the winning price (the seller loses the card fee).

5. Earn points or credit cards at the card company by subtracting the purchase cost that reflects the winning price from the amount paid in advance. (It may be possible to make cash at any time.)

6. Earn points or cyber money on the operation site by subtracting the purchase price that reflects the winning price from the amount paid in advance (you can make it cashable at any time).

In the joint purchase method according to the present invention, the following step (or means) may be further added.

A part (or means) in which part or all of the paid purchase costs are returned to the purchase cancellation penalty (in consideration of variable benefits) and the balance (or more) is refunded (in consideration of variable benefits) if the balance remains;

-If this step (or means) cancels the application for purchase after determining that the purchaser has made a purchase, it may cause damage to the seller. It is a step (or means) to recover the loss of the seller and guarantee the reliability of the transaction by returning it (in consideration of the variable benefit) to the seller.

That is, from the seller's point of view, all the buyers who applied for a purchase purchased the product by lowering the selling price as much as possible by calculating the profits from the sales, in the judgment that all buyers who made the purchase were determined to purchase. If canceled, even if the sale of the successful bid product may be much reduced or even damage than originally thought, the buyer to cancel the purchase application is given a predetermined penalty.

-This step (or means) is intended to secure a deposit from the seller (primarily in order to compensate for the loss of the concluded buyers, which may occur if the canceled buyer does not make a good sale even if the buyer concluded the purchase). In the event of a sale application), if the payment is made in advance and the seller does not fulfill his obligations later, part or all of the pre-paid sales deposit will be provided to the buyers who made the purchase (in consideration of the variable benefits). This is to secure.

After the buyer concludes the purchase,

When the cancellation of sales is accepted from the sales application terminal used by the seller through the co-purchase server or the information that the seller has not fulfilled the obligation under the seller's right to be granted to the seller, the pre-payment of the security deposit paid in advance (in consideration of the variable benefit) ) Or

Reimbursement (or means) of the sales deposit (above) to the seller (in view of the variable benefits) if a normal transaction is made;

If the transaction is successful, the sales deposit will be refunded to the seller.

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

After the successful bid is determined through the joint purchase server,

When implementing the method of the present application, in most cases, the "purchase request corresponding to each purchase request benefit is greater than the cumulative purchase request amount purchased below the purchase request benefit is greater than the lower limit of the condition of the purchase request quantity section". The lowest purchase offer benefits will be enforced as a rule that determines the winning bid, but the seller (or site administrator) may apply for purchases under the purchase offer benefit for each purchase offer benefit, subject to discretion or specific rules. This means that the cumulative purchase application quantity may add a certain benefit to "the best benefit among the purchase application benefits corresponding to a larger quantity than the lower limit of the purchase application quantity interval condition."

The additional discount is applied to the method of determining the successful bidder, characterized in that the following method.

Successful bid price = A-B

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

B: Additional discount amount = C * D / E

In the formula for B above,

C is the number of the purchase offer price in the section to which the total purchase order volume belongs, minus (or close to) the price of the purchase request in the next section (toward the larger quantity of purchase requests) of the section to which the total purchase order quantity belongs.
