Created by APPANET, the military's Defense Advanced Research Projects Agency (DARPA) for efficient information sharing for military purposes, the Internet (INTERNET) is evolving and is currently being deployed worldwide in mail, newsgroups and web services. It is used for various purposes such as communication between computers, collection of information, and public relations means of companies and individuals.

As the Internet is out of the specific purpose of the initial use, as the number of Internet users has increased rapidly in recent years, commercialization through the Internet is rapidly spreading, and various forms of Internet business have been proposed.

The Internet business can be broadly classified into an information provider (IP: Infomation Provider) that receives a certain amount of information provision costs and provides a plurality of desired information to clients accessing the service provider's homepage through the Internet. It can be classified into a network service that allows users to simultaneously play a game through a network and an e-commerce service in which goods and services are traded between a company and an individual or a company and a company online.

Among the Internet services classified as described above, the field of electronic commerce (EC) through computer terminals is the most popular and many new items are being developed one after another.

In addition, e-commerce started with B2C is shifting its center of gravity to B2B, an inter-company e-commerce, and it is expected that e-commerce between companies for the procurement of necessary goods will be activated soon. However, as the market is still in the formation stage, it is urgent to introduce a new business model that enables e-commerce for such products with various specifications and types.

In particular, industrial equipment distributed between a company and a company is produced by various companies according to its use environment, purpose of use, or purpose, and is produced by order production. It is impossible to purchase at the published discount rate.

In addition, payment methods for industrial equipment are often traded in large amounts, unlike ordinary retail products, and the structure of paying the price after receipt of goods is firmly practiced, so postpay payment is preferred to prepayment. have.

Meanwhile, the e-commerce type joint purchase method operated on the Internet until now suggests a single joint purchase price or a gradual discount rate based on the quantity of joint purchases for a specific single product, and the buyer acquires only information on the specific single product. Will decide to buy.

In this case, the joint purchase service operator selects a seller selling directly a specific single article or an expected quantity of a joint purchase directly through the Internet, and presents the purchaser with a single price applied with a predetermined discount rate or a gradual discount rate according to the purchase quantity. Buyers will be offered to Buyers at the price suggested for the quantity ordered by the Buying Deadline.

Accordingly, the present invention has been made to solve the above-mentioned shortcomings and problems raised in the conventional general co-purchasing method, and a service provider provides a co-purchase of inter-company equipment from a plurality of purchasers and vendors through a website. Collect the purchase of products and product opinions, and make joint purchases of all the specifications of products that are handled by one vendor for the period of joint purchase, according to the total amount of joint purchases determined in advance according to the total purchase amount of multiple purchasers. The price is reduced according to the discount rate of individual products, allowing buyers to select and purchase products with the required specifications, and provide a method of joint purchase between companies of industrial equipment with various specifications to make joint purchases for specific companies. There is an object of the invention.

In addition, the other purpose of the joint purchase method of the enterprise equipment of the industrial equipment with various specifications of the present invention is to deposit a predetermined down payment or a guarantee certificate to the authorized payment agency or guarantee agency to the purchaser when the purchaser applies for joint purchase In order to prevent the involuntary participation or termination of the joint purchase, the purchaser who has done this is entitled to a normal joint purchase application and the company's joint purchase application amount is included in the total amount to induce an increase in the discount rate.
