Description

Method for setting up the purchasing price discount and buying the user request of a goods}

The present invention relates to a product purchase made through an online product purchase site, and in particular, when a buyer requests a product purchase, which is a demand group of the product, information of the product according to the purchase request (for example, the product manufacturer, price, and A / S status) Search, etc.) to ensure that the best product with high quality or price satisfaction is delivered to the buyer, and that the sales of the product are made from the determined demand group, that is, the buyer's choice of purchase. The purchase price of the product shall be divided into fixed discount rate and linked discount rate according to the number of buyers.In addition, if the purchase is rejected with the discount width applied, the discount width may be reduced or stopped according to the number of rejection of the purchase. On the other hand, if the number of purchase rejections is severe, the handiculate that restricts the purchaser of the product The present invention relates to a method of purchasing a product by a request of a consumer and a method of setting a discount width of the purchase price so that the online commerce order can be more clearly established by applying ap).

In the conventional offline product purchase, a buyer visits a store or selects a desired product through a print medium such as a catalog and a broadcast medium of home shopping, and then orders the selected product.

However, the above method is not only a one-to-one correspondence between the buyer and the seller, but also a method of producing and selling a product by predicting the buyer's demand, which means that if the buyer's demand is out of stock, There was a disadvantage that occurred, and the discount of the purchase price for the product was made only by the seller.

Accordingly, in the past, a shopping site in which the ordering and delivery of goods online is made through a computer based on internet technology has been established. In such a shopping site, a discount of a sale price for a product is determined by the purchaser's participation. It has led to the development of a joint purchase method.

That is, the joint purchase method sets the deadline and the deadline while setting the number of buyers.

Then, when the number of buyers set according to the deadline and the deadline is filled, the purchase method of discounting the purchase price for the product to the buyers according to the number of people.

However, the joint purchase as described above is a fixed form in which the discount for the product is applied as it is even if the set number of buyers is exceeded.

In addition, the joint purchase on-line has not been driven by the buyers the way of purchasing the goods, but proceeded to the seller-driven type whose quantity is determined by the seller, that is, the shopping site as in the offline.

Meanwhile, in the conventional joint purchase, even if the purchaser withdraws the purchase request for the product while satisfying the conditions of the joint purchase of the product, a significant economic loss to the seller of the product due to the contradiction in which the discount of the already applied product is applied as it is. It had the disadvantage of causing.

In other words, the seller can minimize the profit margin through the mass sale of the product while minimizing the profit on the product. If the buyer who requested the joint purchase withdraws the purchase request as described above, The loss inevitably occurred, and this loss had a structural disadvantage of returning to the seller.

In this regard, sanctions should be imposed according to the withdrawal of the purchase request. However, in the conventional joint purchase method, no safety device for sanctioning the buyer was provided, and accordingly, the order of commerce became quite turbid.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to make the product purchase by the buyer, which is the demand layer of the product, the development and manufacture of the product according to the demand layer In addition to preventing unnecessary investment in commodities, the company can deliver products of the highest quality to buyers based on accurate information on the commodities while reducing waste of finance, interest rates and warehouse management costs by eliminating distribution of commodities in distribution. It is intended to provide a method of purchasing a product at a request of a consumer and setting a discount width of the purchase price so that the purchase price can be made inexpensively.

In addition, the present invention is to ensure that when a product is purchased from the product purchase site, the discount width according to the purchase is divided into a fixed discount rate and a linked discount rate according to the number of buyers, so that the more buyers, the greater the discount width It is intended to provide a seller to expand the sales channels of goods, as well as to provide a buyer with a method of setting a discount on the purchase price of the product and the purchase price by requesting the buyer to provide a desired product more cheaply.

In addition, the present invention, if the purchase rejection is made in the state where the discount width is applied, the discount width is reduced or stopped according to the number of the rejection of purchase, while the number of purchase rejection is severe, limiting the purchase of goods by the buyer By establishing a safety device that applies a handicap, the purchase of goods by the request of the consumer and the purchase of the goods are more clearly established by minimizing the loss of the seller due to the rejection of the purchase request by the buyer. The idea is to provide a way to set the price range.

Here, the bonus may be given a point reserve or cyber money in addition to the Internet gift certificate, but is not necessarily limited to this.

Referring to Figures 1 to 3 attached to the operation of the embodiment of the present invention configured as described above are as follows.

First, a product purchase site 300 of a product sale is opened on the Internet, and the opened product purchase site 300 is managed through a web server 400.

Thereafter, when the buyer accesses the product purchase site 300 through the computer 100 and the internet network 200, the web server 400 induces the purchaser to register.

When the purchaser joins from the above induction, the analysis unit 10 built in the web server 400 analyzes the inputted information when the purchaser inputs the information necessary for registration through the computer 100. Then it is sent to the member management unit (20).

Then, the member manager 20 registers the buyer as a member based on the analysis information sent from the analyzer 10, and stores and manages the registered information in the member information DB D1.

Here, when the purchaser who completes the membership registration process as described above requests a product purchase through the authentication process of the authentication management unit 30 built in the web server 400, the purchase management unit built in the web server 400 ( 40 receives and manages a purchase request when a registered purchaser requests a product, and transmits the received information to the count management unit 70 built in the web server 400.

In addition, the demand product management unit 60 built in the web server 400, the product information DB (D2), as well as through the manufacturer's homepage, etc. of the product of the buyer's purchase information to analyze the information after the precise analysis Based on the purchase price for the product, as well as the deadline period of the joint purchase and the number of people applying the discount rate according to the number of people, the purchase decision unit 80 guides the buyer to determine the way of purchasing the product.

At this time, when the buyer decides to purchase the goods alone, the purchase decision unit 80 receives the payment by delivering the goods to the buyer at a predetermined price based on the result analyzed by the demand product management unit 60.

On the other hand, when the buyer decides to make a joint purchase, the purchase decision unit 80 waits for the buyer to deliver the goods until the deadline of the joint purchase, and during the waiting period, the count management unit 70 determines the deadline of the joint purchase. To count.

That is, the purchase decision unit 80 manages the price information of the product according to the simultaneous application of the fixed discount rate and the linked discount rate as well as the individual application of the fixed discount rate and the linked discount rate according to the number of buyers, and the count management unit 70 When a joint purchase decision is made on a buyer's product, the buyer sets a deadline for multiple buyers to make a purchase request for the product and applies a fixed or interlocking discount to the product. It counts until it waits for the buyer to deliver the goods.

At this time, if the period of the joint purchase counted by the count management unit 70 has ended, the count management unit 70 is determined that the number of buyers required for the joint purchase is less than the target number or meet the target number It is determined whether or not it exceeds the target number.

When the determination result is less than the target number of people according to the joint purchase of the product, the count management unit 70 transmits the underdelivery state to the purchase decision unit 80,

The purchase decision unit 80 is a price calculated by analyzing the sales price of the product by the demand commodity management unit 60 because the co-purchase conditions of the product to be currently sold to the computer 100 of the buyers requesting a purchase are insufficient. Not only does it send a message indicating that it has been purchased, it also asks buyers to purchase the product at a calculated price.

When the purchaser decides to purchase a product, the purchase management unit 40 built in the web server 400 inquires whether the purchaser's computer 100 has a bonus, that is, an Internet gift certificate. If there is an Internet voucher, you will be asked if you want to use it.

As a result of the above query, when the purchaser has an internet voucher granted and selects a willingness to use the existing internet voucher, the purchase management unit 40 deducts the amount indicated on the internet voucher from the sale amount of the product and then gives the purchaser I was supposed to receive payment of the goods.
