Description

Price fluctuation using the joint purchase tag Joint purchase system and service method {FLUCTUATIONS IN PRICES COPERATIVE BUYING SYSTEM AND SERVICE METHOD USING COPERATIVE BUYING TAG}

The present invention relates to a joint purchase system and a service method, and more specifically, joint purchase tags, sales conditions setting, and based on this, the product price that changes in real time according to the cumulative sales quantity and the joint purchase through the refund system of the prior purchaser The present invention relates to a price change joint purchase system and a service method that can maximize participation rate and price discount rate, and finally provide a result of all buyers purchasing products at the lowest price.

With the spread of computers and the development of the Internet, electronic commerce has been actively conducted. E-commerce saves shopping time and makes it easier to compare products by allowing consumers to select, order, settle, and deliver products through a computer network at work or at home without having to visit the store. There are many advantages. One of the considerations that consumers consider particularly important in the trade of goods through the Internet is the low price of goods, and one of the widely used methods of selling products in line with these expectations 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 types.

The first method is a partnership between a co-purchase site operator and a seller of a product. The co-purchase site operator approves a specific seller as a member, and then describes a product to be sold, a quantity of a product, a selling price, and a sale period. It is a method of recruiting buyers by registering sales information and posting corresponding product information on a website.

In the second method, a predetermined period is set, together with potential purchasers who want to purchase a certain product during the period, the purchase quantity of the product is determined, and the seller of the product is secured to derive the joint purchase price.

However, in the first approach, a single joint purchase price, common

Only the deadline for purchase and the number of joint purchases are presented, and the consumer participates in the purchase based only on the suggested price. In such a case, the co-purchase site operator negotiates with the co-purchase company who is trying to sell the goods through the Internet at a single price only with the expected amount of the co-purchase, and presents only a single price to the buyer. This results in supplying the buyer at a single price with the quantity ordered by the deadline for the joint purchase, and when the number of buyers is small because the joint purchase site operator or joint purchaser cannot predict the exact quantity of the expected sales. Inevitably, the price of commodities must be set at high prices.

As described above, even if a bulk purchase exceeding an expected sales price for a particular joint purchase product is generated later, the discounted price for the joint purchase is hardly returned to the buyer, and if the quantity sold is smaller than the expected sales price, the seller also loses the amount. There was a problem that does not live up to the original purpose of the joint purchase.

In addition, there was a problem that it is difficult to induce a large number of co-purchasing because it had a limited number of buyers targeting only users connected to a particular co-purchase site.

In the case of the second method, the expected sales value is relatively accurate and easy to calculate, compared to the first method, and thus, there is an advantage in setting a reasonable and low priced product price. However, the joint purchase participant's recruitment period is over. There was a problem that it takes a long time to purchase a product until the product can not be purchased and received.

The present invention has been made to solve the above problems, the object of the present invention is to purchase and receive goods immediately even during the progress of the joint purchase, as well as the selling price of the corresponding product automatically changes as the sales volume increases By repaying the difference to the pre-purchaser who purchased before the additional discount of the selling price, the seller can secure the profit model without predicting the expected sales value, and the buyer can achieve the immediate purchase of the joint purchase product. It is possible to get back as much as the discount generated in the future, but also to provide a price change joint purchase system and service method using a joint purchase tag that can maximize customer satisfaction and attract buyers.

Based on the product price for each 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 the product price according to the cumulative sales quantity in real time. It comprises a joint purchase processing unit for calculating the difference between the purchase price of the pre-purchasers by price range of the final purchase price at the end of the sale of the joint purchase products.

According to the price change joint purchase system and service method using the joint purchase tag according to the present invention, the joint purchase tag, the terms of sale and based on the product price that changes in real time according to the cumulative sales quantity and the differential refund system of the preceding buyer Through this, it is possible to maximize the joint purchase participation rate and the price discount rate, and finally, all the buyers have a remarkable effect of providing the result of purchasing the product at the lowest price.
