Description

[0001] Joint procurement system and service method [0002]

The present invention relates to a joint purchase system and a service method, and more particularly, to a joint purchase system and a service method in which a joint purchase tag, a sale condition setting, The present invention relates to a system for collectively purchasing a price variable and a service method using the collective purchase tag which can maximize the participation rate and the discount rate and ultimately provide the result that all the buyers purchase the goods at the lowest price.

With the spread of computers and the development of the Internet, electronic commerce is actively being carried out. E-commerce allows consumers to select products through computer networks at home or at home and process orders, payments, and shipments without having to go directly to the store, saving shopping time and easily comparing various products There are many advantages such as. One of the most important considerations consumers consider to be in the commodity trading through the Internet is the low price of commodities. In line with this expectation, one of the most widely used commodity sales methods is the joint purchase system.

The joint purchase system based on the Internet is also a kind of electronic commerce, and the conventional joint purchase system can be divided into two ways.

The first method is an association method between a joint purchasing site operator and a product seller. After the joint purchasing site operator approves a specific seller as a member, a description of the product to be sold and a description of the sales quantity, It is a method to collect the sales information of the product and recruit buyers by posting the product information on the website.

In the second method, a predetermined period is set, and a planned number of purchased products is determined together with prospective purchasers who want to purchase an arbitrary commodity during the period, and then a seller of the commodity is acquired to derive a joint purchase price.

However, in the first case, a single joint purchase price,

The purchase deadline, and the number of joint purchasable quantities are presented. In this case, the operator of the joint purchase site negotiates with the joint purchase prospect who intends to sell the goods through the Internet with a single price only with the joint purchase expectation quantity, and presents only a single price to the buyer. Therefore, it is a result of supplying the buyer with a single price that shows the order quantity until the joint purchase deadline, and it is difficult to predict the exact quantity of the expected sales value by the joint purchaser site operator or the joint purchaser. Therefore, The price of the product can not be determined at a high price.

As described above, even if a large quantity purchase exceeding the expected sales value occurs for a specific joint purchase item later, it is difficult for the joint purchase price discount benefit to return to the buyer, and if the quantity smaller than the expected sales value is sold, There is a problem in that it can not make use of the intention of the joint purchase in the end.

In addition, there is a problem that it is difficult to induce a large amount of joint purchases because the purchaser has a limited purchaser who is targeted only to users who access a specific joint purchase site.

In the case of the second method, it is relatively accurate and easy to calculate the estimated sales value as compared with the first method. Therefore, it is advantageous to set reasonable and low price of the commodity. However, There is a problem that it takes a lot of time to purchase the product because it is not possible to purchase the commodity and collect the commodity until the end.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method and system for automatically purchasing and receiving a commodity even during a joint purchase, In addition, by refunding the difference to the purchasers who have purchased before the additional discount of the sales price, the seller can securely obtain the profit model without prediction of the expected sales value, and the buyer can immediately purchase the joint purchase item The present invention provides a system for collecting price fluctuations and a service method using cooperative purchase tags that maximize customer satisfaction and attracting co-purchasers, which can be achieved but can be returned as much as the subsequent discounts.
