Description

Group purchase service method and system including compensation system according to contribution}

The present invention relates to a group purchase service method and system, and more specifically, group purchase tags, sales conditions settings, product prices that change in real time according to the cumulative sales quantity based on these, and group purchase through a difference refund system for advance purchasers. It is about a group purchasing service method and system that includes a compensation system based on contribution that can maximize the participation rate and price discount rate and ultimately provide the result of all buyers purchasing the product at the lowest price.

With the spread of computers and the development of the Internet, electronic commerce is actively taking place. E-commerce allows consumers to select products, process orders, payments, and delivery through a computer network at work or home without having to visit a store in person, saving shopping time and making it easier to compare various products. There are many advantages, including: One of the considerations that consumers consider especially important when trading products through the Internet is low product prices, and one of the product sales methods that has been widely used recently in line with these expectations is the group purchasing system.

The Internet-based group purchasing system is also a type of e-commerce, and the conventional group purchasing system can be broadly divided into two methods.

The first method is a partnership method between the group purchase site operator and the product seller, where the group purchase site operator approves a specific seller as a member and then provides a description of the product to be sold, sales quantity, sales price, sales period, etc. This is a method of recruiting buyers by registering product sales information and posting the product information on a website.

The second method is to set a specific period, determine the expected purchase quantity of the product with prospective buyers who wish to purchase a certain product during that period, and then secure a seller of the product to derive a joint purchase price.

However, in the case of the first method, only a single group purchase price, group purchase deadline, and quantity available for group purchase are presented for a specific product, and the consumer participates in the purchase by only looking at the price presented. In this case, the group purchase site operator negotiates a single price with the group purchase company that wants to sell products through the Internet, based only on the expected group purchase volume, and also presents only a single price to the buyer. Therefore, the result is that the ordered quantity is supplied to the buyer at a single price until the group purchase deadline, and it is difficult for the group purchase site operator or group purchase company to predict the exact quantity for the expected sales value when the number of buyers is small. We have no choice but to set product prices at a high price to prepare for this.

As mentioned above, even if large purchases exceeding the expected sales price for a specific group purchase product occur in the future, it is difficult for the resulting group purchase price discount to go to the buyer, and if the quantity sold is less than the expected sales price, the seller also There was a problem that the original purpose of group purchasing was not realized due to losses.

In addition, because it had a limited buyer base targeting only users who accessed a specific group purchase site, there was a problem in inducing mass group purchases.

In the case of the second method, compared to the first method, the calculation of the expected sales value is relatively accurate and easy, so it has the advantage of setting a reasonable and inexpensive product sales price. However, group purchasing participants have a period of recruiting prospective buyers of the group purchasing product. There was a problem in that it took a long time to purchase a product because you could not purchase or receive the product until it ended.

The present invention was created to solve the above problems, and the purpose of the present invention is to enable the product to be purchased and received immediately even during group purchase, and the selling price of the product is automatically changed as sales volume increases. By refunding the difference to advance purchasers who purchased before the additional discount on the sales price occurred, sellers can secure a stable profit model without having to predict expected sales, and buyers can purchase group-purchased products immediately. The goal is to provide a group purchase service method and system that includes a compensation system based on contribution that can maximize customer satisfaction and attract group buyers by allowing the customer to receive back the amount of the discount generated in the future while still being able to achieve it.

To achieve the above purpose, the price change group purchase system using a group purchase tag according to the present invention stores product sales conditions including at least the sales start date, sale end date, and product price by cumulative sales quantity for a specific group purchase product, and Conditions of sale in storage; A payment information storage unit that stores sales and payment-related information that occurred for a specific group purchase product; And by generating and issuing a unique group purchase tag for a specific group purchase product of a specific seller, the specific seller can copy the group purchase tag through the seller device and expose it to the web environment, and store the group purchase tag in the sales conditions storage. Based on the product price by cumulative sales quantity and the cumulative sales quantity calculated from the payment information storage unit, the current selling price of the product is derived and provided by checking the change in product price according to the cumulative sales quantity in real time, and the group purchase product It is configured to include a group purchase processing unit that settles the difference between the purchase price of advance buyers in each price range and the final product price at the end of sale of the group purchase product.

According to the price change group purchase system and service method using the group purchase tag according to the present invention, the group purchase tag, sales conditions settings, product prices that change in real time according to the cumulative sales quantity based on this, and a refund system for the difference for advance purchasers Through this, the group purchase participation rate and price discount rate can be maximized, and ultimately, it has the remarkable effect of providing the result that all buyers purchase the product at the lowest price.

In addition, through the group purchase tag of the present invention, it is possible to advertise the product in various web environments, so that not only the buyer base limited to a limited site but also the buyer base of linked sites can be absorbed, thereby securing more buyers. And since it is possible to digest large quantities through this method, it has the remarkable effect of inducing a more rapid price decline.

In addition, through the distributor profit sharing system of the present invention, sellers who carry out group purchases can naturally induce active promotion of their products, thereby further increasing the attraction of group buyers, and as a result, the discount rate of product prices increases. As it increases further, there is an outstanding effect of leading to the participation of more group buyers and consumer discount benefits.

In addition, while implementing the purpose of group purchasing of multiple purchases, buyers have the advantage of being able to immediately purchase and receive the product even while the group purchase is in progress.

In Figure 4, it appears that a plurality of group purchase tags are visually provided, divided by a number of representative portal sites (NAVER, DAUM, Paran, etc.), but this is for the visual convenience of sellers who wish to copy the group purchase tag. In addition, the group purchase tags that are matched to each of the above-categorized targets (NAVER, DAUM, Paran, etc.) are ultimately the same group purchase tag.

The present invention provides group purchase tags in three forms. The first is the image format that can be used on the image bulletin board (600), the second is the HTML format (601), and the last is the URL format (602).

An example of the source code that copies to the clipboard to provide the group purchase tag 600 in the form of an image to the web environment is implemented with JavaScript "function copy_all()".

function copy_all()

{

var text = document.item.document.body.createTextRange();

text.select();

text.execCommand("Copy");

}

The first var text sentence specifies the area of the image to be copied, the second text.select() sentence is a command to select the area, and the last sentence is a command to copy it to the clipboard of the seller device 200.

The source code provided in HTML format (601) is

function copy_html(){

var ele = document.item.document.body;

var maintext = ele.innerHTML;

window.clipboardData.setData("Text", maintext);

}

An example is to save an object in document.item.document.body, save it in a variable in maintext, and copy the contents to the clipboard of the seller device 200.

The source code provided in URL form (602) is

function copy_link(){

var maintext = "http://www.eummoney.com/mc/index.jsp?mc_id=Separator identifier";

indow.clipboardData.setData("Text", maintext);

}

It can be implemented with

In the above three types of deposit windows, “http;//www.eummoney.com/mc/index.jsp?mc_id=identifier (610)” is recorded as meta information.

In addition, when the group purchase tag of the present invention is exposed in the form of an image, the name, contact information, and other necessary information of the group purchase company can be included in the image and displayed to the purchaser.

Figure 5 is an example showing how the group purchase tag of Figure 4 is copied and exposed to the web environment.

As shown in FIG. 5, the seller simply copies the group purchase tag uniquely issued for a specific group purchase product through the seller device 200 and pastes it on the desired web page to complete the preparation of the payment information method.

Figure 5 shows a group purchase tag in the form of an image copied and published in a cafe (10) called “Catch up with the latest PMP” on a specific portal site.

Afterwards, if any buyer who encounters the group purchase product posted on the cafe decides to purchase the product and wants to proceed with payment immediately, the actual payment is completed by clicking on the group purchase tag exposed in the web environment. You can do it.

Figure 6 is an example of a payment window provided when the group purchase tag of the present invention is clicked.

As shown in FIG. 6, when a random group purchase applicant clicks on the group purchase tag through the purchaser device 300, the group purchase tag is used to proceed with payment for a specific group purchase product matching the group purchase tag. The payment window 620 is provided through a pop-up method or the like.

The payment window 620 includes a product name field 622, a current selling price field 621, a payment method selection field 623 requesting selection of a payment method, and a delivery address information input field 624.

The product name field 622 refers to the name of the product the buyer wishes to purchase, and the payment method selection field 623 indicates the payment method the buyer wishes to use among various payment methods such as credit card, account transfer, and mobile phone payment. Asks for a choice. The delivery address information input field 624 refers to an input field for entering the address at which the purchased product will be received.

In particular, the current selling price field presented in the payment window 620 is one of the main technical ideas of the present invention, which means the selling price of the group purchase product at the time the group purchase applicant clicks the group purchase tag, and the current selling price field is one of the main technical ideas of the present invention. The current selling price presented in the selling price field may change each time the group purchase tag is clicked.

When the buyer device 300 clicks on a group purchase tag exposed in an arbitrary web environment, the group purchase processing unit 110 of the present invention presents a product sales price that changes in real time according to the cumulative sales quantity, at a specific click time. The process of deriving the product sales price corresponding to is as follows.

That is, the product price according to the cumulative sales quantity set by the seller in the sales condition storage unit 130 of the group purchase processing unit 110 and the cumulative sales quantity up to the time of pressing the group purchase tag are based on the product according to the cumulative sales quantity. By checking price changes in real time, the current selling price of the product is derived and provided.

In addition, the standard for calculating the cumulative sales quantity up to the time of pressing the group purchase tag is the cumulative sales volume when an event occurs in which the group purchase system 100 is notified of payment approval-related information generated during the payment activity of the advance purchaser. Various standards can be set, such as deriving the latest cumulative sales quantity by reflecting the sales quantity, or reflecting the event in which the purchaser is notified of the purchase decision after payment is completed and product delivery is completed.

The conventional group purchase system predicts the expected sales value and definitively sets the price of the group purchase product, and then uniformly applies the set sales price regardless of the subsequent sales quantity. In contrast, the group purchase system according to the present invention (100 ) is able to clearly implement the purpose of group purchasing of multiple discounts by automatically changing and providing product sales prices in real time according to the increase in sales quantity through the system operation described above.

As described above, the group purchase processing unit 110 according to the present invention reflects the increase in sales volume in real time during the sales period of the group purchase product and presents the current selling price of the product.

Therefore, during the sales period, there will be buyers of various price ranges for the group purchase product. In particular, advance buyers who purchase the product in the early stages of sales when the cumulative sales volume is low will purchase the product at a higher price than subsequent buyers. A problem may arise in which advance purchasers may not be able to benefit from price discounts due to increased sales of the group purchase product.

In order to solve the above problems, the group purchase processing unit 110 of the present invention is configured to perform a difference settlement function for advance purchasers.

The advance purchaser difference settlement function refers to the operation of calculating the difference between the purchase price of the advance purchasers in each price range of the group purchase product and the final product price of the group purchase product and returning the difference to the corresponding advance purchaser.

According to the present invention, the purchase price varies depending on when a specific group purchase product is purchased. In particular, if sales volume steadily increases, the sales price is bound to vary greatly, and accordingly, a public auction purchase is in progress during a specific sale period. Even for a specific product, there are buyers in various price ranges.

Therefore, the group purchase processing unit 110 of the present invention refers to the payment information storage unit 140, which stores payment-related information of various prior purchasers, calculates the difference in price for each prior purchaser, and then sends a payment corresponding to the difference. The refund will be made in at least one selected from cash, kind, and cyber money.

The final product price that serves as the standard during the difference calculation process refers to the product sales price corresponding to the cumulative sales volume at the end of the sales period set for the group purchase product.

In the above, the payment window 620 is provided in a pop-up form as soon as the group purchase tag of the present invention is clicked, but of course, it can also be configured in a modified form as follows.

In other words, when you click on the group purchase tag, it contains product sales information including at least the sales start date of the product, the sales end date, the product price by cumulative sales quantity, the current sales price of the product, and an explanation of the standard for refunding the difference after the end of the sales period. The product information window is opened first, and a payment window activation button is separately provided in a predetermined area of the activated product information window to activate the payment window 620 described above.

In addition, in the above, the member information storage unit 150, the product information storage unit 120, the sales conditions storage unit 130, and the payment information storage unit 140 are explained and shown as separate and independent components, but this is not an example of each component. This is only to clearly explain the functions and roles of , and it is obvious to those skilled in the art that they can be configured to be stored and managed in a hierarchical format in one integrated storage.

Referring to FIG. 7, the price change group purchase service method using the group purchase tag according to the present invention includes a web environment provided on the Internet such as a homepage, blog, cafe, email, etc.; a seller device 200 and a buyer device 300 for accessing the web environment; Based on the group purchase system (100), which registers the seller as a group purchase company and processes group purchase-related tasks, the sales price changes in real time according to the increase in the sales quantity of the group purchase product, and discounts are provided according to the change in sales price. This will be done so that the benefits can also be returned to advance purchasers.

To explain the work flow in detail, first, a seller supplying a group purchase product applies for a group purchase process in the group purchase system of the present invention, becomes a member (S10), receives a seller registration code (S11), and then becomes a registered seller. By registering the group purchase product you wish to sell in the group purchase system (S12), the group purchase process for the product begins.

A seller who has registered a specific group purchase product will be requested to set product sales conditions for the group purchase product, including at least the sales start date, sales end date, and product price by cumulative sales quantity, and upon request, the seller will request to set the product sales conditions. The group purchasing system that has been set stores this in the sales conditions storage (S20).

Once the registration of the group purchase product and the setting of product sales conditions are completed, a unique group purchase tag is created and issued to the group purchase product, and the issued group purchase tag can be copied and exposed to the web environment. (S30 )

As described above, the group purchase tag uniquely issued to a specific group purchase product can be copied not only by the seller of the product but also by other members of the public and exposed to various web environments (S31).

When a random buyer clicks the group purchase tag exposed in the web environment (S32), a payment window including a product name field, a current sales price field, and a payment method selection field is provided (S40), and the payment window displayed in the current sales price field of the payment window is provided. The current selling price is based on the product price according to the cumulative sales quantity set in the "S20" step and the cumulative sales quantity up to the time the group purchase tag is pressed. The previous step is to check in real time the change in product price according to the cumulative sales quantity. It is calculated through (S35)

A buyer who has decided to purchase the group purchase product can proceed with the actual payment through the payment window guidance provided in a pop-up format when the group purchase tag is clicked.

When a payment is made using a method such as a credit card, mobile phone, or bank transfer, the payment information is transmitted to the electronic payment company (S50), and the electronic payment company that receives the payment information approves the transaction and then Predetermined information about payment is transmitted to the group purchasing system (S51).

The above-mentioned payment information refers to information on the purchase status of the product in which the transaction occurred, such as product name, payment amount, name of the payer, payment date, and purchase quantity.

The group purchasing system that has received the payment information notifies the payment occurrence information to the group purchasing company that registered the group purchase product for which payment occurred (S60), and the group purchasing company that has been notified of the payment occurrence information includes the information included in the notification. The product is delivered to the buyer based on delivery information, name of the payer, purchase quantity, etc. (S70).

Then, the buyer who has received the product confirms the received product and transmits the final purchase decision to the group purchase system (S8 0), thereby completing the group purchase process for one buyer.

The final purchase decision can be delivered through the group purchase tag clicked by the buyer or by directly accessing the group purchase system.

When the final purchase confirmation is communicated through a group purchase tag, a final purchase confirmation button is displayed in a designated area of the payment window or product information window provided when the group purchase tag is clicked, and when the final purchase confirmation button is clicked, login and personal information are provided. By requesting the input of unique information such as details and purchase product identification number, the final purchase intention can be received after authenticating the recipient.

If steps "S35 to S80" are repeatedly performed through the participation of multiple group buyers during the sales period set by the seller for a specific group purchase product, the sales volume of the group purchase product increases and the sales price of the product increases accordingly. It will gradually go down, and when the sales period ends, the final sales price of the product is confirmed.

When the sales period set by the seller ends as described above, the difference between the purchase price of the preceding purchasers in each price range of the group purchase product and the final selling price of the group purchase product is calculated, and when the difference occurs to a specific advance purchaser, the difference is calculated. A refund or accumulation is made using at least one selected among cash, physical money, and cyber money corresponding to the difference (S90).

In addition, for sales generated through group purchase tags exposed by distributors other than sellers, the profits are distributed based on the group purchase tag distributor profit distribution conditions stored in the sales conditions storage, and the sales period of the group purchase product All transactions for the group purchase product are completed by settling the payment amount incurred during the period to the group purchase company (S100).

In addition, when you click on the group purchase tag, it contains product sales information, including at least the sales start date of the product, sales end date, product price by cumulative sales quantity, current sales price of the product, and explanation of the standard for refunding the difference after the end of the sales period.
