The present invention relates to a messenger e-commerce joint purchase system, and operates in two e-commerce methods. That is, intermediary co-purchase method and spontaneous co-purchase method. Intermediary co-purchasing is a method whereby an intermediary conducts a survey of the co-purchases of pre-registered co-buyers through this system, then requests quotations from a number of pre-registered sellers for the results of this demand survey, The seller chooses a seller and then deals with the co-buyer and the seller. On the other hand, the spontaneous joint purchase method selects a company that provides optimal sales conditions by requesting a quote from a number of registered sellers by a particular joint purchaser who conducts a demand survey on other joint purchasers. After that, the co-purchaser and the seller directly deal with the co-purchaser themselves.

Co-purchase at cyber shopping malls is becoming more common. For co-purchase through existing cyber shopping malls, the seller who wants to provide co-purchase information must own the server or participate as a tenant of a large cyber shopping mall, and enter information on the items he / she wants to sell. You can access the information on the Internet, search for commodity information organized by the seller, and make joint purchases. Moreover, in the case of joint purchases on cyber shopping malls, the purchase price is lowered only when a certain amount of quantity is ordered within a certain period. This is in stark contrast to the principle of trading, in which co-purchasers buy themselves commodities at a certain time for a particular item, which in turn favors them.

The purchase of the goods by the above method can be made only when the co-buyer visits the cyber shopping mall of the seller directly, and the co-buyer must identify the site where the desired items are among the numerous sites on the Internet and compare the items to be purchased. To visit multiple merchant sites. In short, co-purchase of shopping malls allows co-buyers to invest a lot of time and effort.

The present invention, in order to jointly purchase a specific item at a specific time in order to co-purchase themselves, first examines the demand for their goods, and receives a plurality of quotations from many sellers for this demand to propose the optimal trading conditions The objective is to develop a system that embodies the economic principles of co-purchasing to select sellers, and there should be a rapid means of communicating information that facilitates co-purchase transactions between many co-buyers and sellers. In order for the trading parties to participate in the joint purchase, the transaction information should be automatically known to the trading parties as soon as they occur. To this end, the present invention has the first technical object to implement a service in an appropriate messenger form that informs the transaction information in real time.

The present invention enables the co-buyers to voluntarily identify the co-purchased goods, collect the purchase quantity easily, and request a quotation from a number of sellers, and select a seller who presents the optimal trading conditions, as well as the co-buyers. The second technical purpose is to implement a system where transactions between the selected sellers and selected sellers can be conducted efficiently, and the documents related to the demand research process, seller selection process, and transaction process are automatically stored on the main server and can be downloaded when needed.

According to the present invention, there is a third transaction intermediary between the co-buyers and the seller in accordance with the transaction method, and there is a co-purchase system for intermediary transactions and a co-purchaser who does not pursue intermediary profits. The third technical objective is to develop a voluntary joint purchase system in which the buyers are asked to offer the best conditions by conducting demand surveys and quotations on behalf of the buyers, and the direct buyers and sellers directly deal with the buyers themselves.                         

In short, all transaction information of intermediary co-purchase and spontaneous co-purchase is transmitted and stored to the main server in real time, and is delivered in real time with a messenger informing the trading partner of the online status. On the other hand, the transaction partner of the offline state sends the transaction information with the messenger notifying the transaction status immediately upon access to the main server. Through the messenger notifying the transaction status, the demands of the co-buyers are collected to request quotations from a plurality of sellers, and the sellers who select the best trade conditions are selected from the received quotations. Its technical purpose is to automatically store the information of all transaction processes until the settlement.

The overall system of the present invention of the instant messenger e-commerce joint purchase system is a joint purchase intermediary that stores a co-buyer member database, a seller's member database, and a goods and services database registered for sale by a seller, a transaction status database, a public homepage, and a private homepage. The main system (hereinafter referred to as 'main server') and the co-buyers and sellers including the co-purchaser are client modules for accessing the main server. However, the private homepage is accessed by using the authentication function in the client module for security.

When co-buyers and sellers use the Internet to access the main homepage of the main server and download the client module, the co-purchase service icon is automatically set up on their computer desktop indicating that the client module of the IM e-commerce co-purchase system was successfully installed. The co-purchase service icon is automatically set in the tray icon. Similarly, the co-purchase service icon is set on the main server desktop, and the co-purchase service icon is set on the tray icon.

Subsequently, the co-buyer and the seller enter personal information in a predetermined member registration form and specify their own ID and password to register as a member, thereby completing the installation of the client module. As a result, when the co-buyer and the seller access the main server through the client module, the co-buyer uses only the co-purchase-only screen, and the seller uses only the screen for the seller.

Since the main server and client modules must be online at all times so that intermediaries, co-buyers and sellers can see the transaction information immediately, the client module for co-buyers and sellers runs automatically when the computer is turned on. Even if the computer is restarted, the client module is automatically executed as soon as the computer is restarted to maintain the connection with the main server at all times.

The messenger appears on the trading party's computer when a new situation arises in the transaction between the parties to the co-purchase transaction. In other words, individual transaction status is stored in a database that stores a series of transaction status information such as demand survey, demand response, quotation request, quotation, notification of quotation evaluation (successful bidding, dropout, or notice of bidding), receipt request, order request, delivery, and acceptance. If a value is entered, the messenger appears on the trading partner's computer. Information that can be sent by messenger includes: demand survey, demand response, request for quotation, quotation, notification of quotation evaluation, receipt status, request for purchase, delivery, acceptance, etc. It can contain other information.

The messenger is a messenger appears frequently on the computer when a transaction occurs vigorously. To prevent this messenger, the messenger can be adjusted from 1 minute to 720 minutes. Also, when a transaction occurs, the messenger makes a specific sound instead of floating. If you minimize the client module, configure the tray icon so that the icon changes to match the transaction.

On the other hand, the seller must register the goods and services to be sold by the joint purchase method. The seller registers the client module by accessing the main server and selecting the item registration menu on the seller-only screen. The classification system for goods and services follows the P2G2 classification system. The seller finds the 8-digit classification number by keyword search or combo box search in the G2B taxonomy database that inputs the classification system of the goods and services to be sold and inputs the 3-digit number in order of the goods or services registered by the seller. Finally enter 11 digits and register the unique model name and image of the item. Registered goods or services information can be modified as necessary.

In the intermediary joint procurement system, there is an intermediary who pursues transaction profits by mediating the joint procurement, whereas in the voluntary joint procurement system, there is a joint procurement leader who does not pursue profits. In the intermediary co-purchase system, there are intermediaries, co-buyers and sellers as trading parties, and in the spontaneous co-purchase system, there are co-purchasers, co-buyers and sellers as trading parties, but co-purchasers are only members of co-purchasers.

There is a quotation status menu, contract status menu, delivery progress menu, and settlement management menu.

The instant messenger e-commerce co-purchase system overcomes the limitations of co-purchase in existing cyber shopping malls and has an invention effect of significantly expanding the bottom of the co-purchase market.

First, existing cyber shopping malls must frequently access numerous sites to search for transaction information. Therefore, time and money will inevitably arise. However, the instant messenger e-commerce co-purchase system does not need to reconnect to the co-purchase once the intermediary (or co-purchaser), co-buyer, and seller have downloaded the user-only program from a specific site. Therefore, there is no time and money to search for co-purchase information.

Second, the joint purchase information of cyber shopping malls cannot be known unless they are directly searched. However, the instant messenger e-commerce joint purchase system automatically provides transaction related information to a counterpart computer through a messenger in real time as soon as the information is generated, so there is no need to collect transaction related information. Even if your computer is offline, the instant messenger will appear immediately when you go online.

Third, the joint purchase is a purchase method that improves the terms of the transaction, such as lowering the purchase price by purchasing the items desired by multiple buyers at the desired time. Ironically, the existing cyber shopping malls sell the desired products in the form of co-purchase at the time desired by the seller. Therefore, there is a contradiction that the buyer can not co-purchase the desired item on time. However, the instant messenger e-commerce co-purchase system allows sellers to register goods to be sold in the form of co-purchase in advance, and the co-buyer selects the necessary items at the time required to co-purchase the actual co-purchase effect.

Fourth, as for the joint purchase, the most important thing is to easily collect a lot of buyers to buy jointly. The more buyers participate, the greater the effect of joint purchase. Co-purchase of cyber shopping malls usually has to wait from one week to full to collect buyers. Therefore, there is an inconvenience in not purchasing at the time when the goods are needed. However, this messenger e-commerce co-purchase system can easily identify many buyers through messenger and collect the purchase volume, resulting in a great co-purchase effect.

Fifth, the joint purchase of cyber shopping malls is suitable for individuals rather than institutions or organizations because they do not provide a joint purchase related book. However, this messenger e-commerce joint purchase system is well suited for joint purchase between institutions or organizations that require transaction document storage and sellers. This is because the system relies on standardized transactions (eg, demand surveys, quotations, orders, tax invoices, etc.) for all transactional procedures, from joint purchasing demand surveys to settlement management.

Sixth, co-purchase of cyber shopping malls mainly deals only with products, because it allows the catalog of products to be registered on the site. However, the instant messenger e-commerce co-purchase system can attach not only an image but also a description, so that not only the goods but also all types of service co-purchase are possible.

Seventh, cyber shopping malls are unable to negotiate co-purchase prices online or are inconvenient. The instant messenger e-commerce joint purchase system receives a quote from a plurality of sellers and can easily negotiate a price.

Eighth, this messenger e-commerce joint purchase system is well suited for intra-university and inter-university joint purchase. Universities are large and crowded, making it difficult to identify co-purchase intentions by phone, fax or e-mail. Therefore, the instant messenger e-commerce co-purchasing system, which can simultaneously grasp the purchase intention of all intra-university or inter-college organizations through messenger and collect the purchase volume, can be most effectively applied to intra-university and inter-university co-purchase. Furthermore, the present invention can be effectively applied to corporations and public organizations located in the industrial complex. As a result, the present invention can improve the efficiency of the purchasing operation of the institution or organization, it is possible to cheap and transparent purchasing, it is possible to significantly improve the purchasing operation.
