Abstract

The present invention relates to a transaction control apparatus and method between buyers and sellers on the Internet, which makes it easy to find a counterpart that meets their conditions using a unified electronic document and allows a user to easily trade. Suppliers receive orders based on the sales period, so they can predict sales volume and selling price. In this case, if the seller is a producer, the cost can be reduced through planned production, so that the seller can sell to the consumer at a lower price. If the seller is a wholesaler, a planned purchase can be made from the producer for efficient inventory management. If the consumer is a producer, the cost can be reduced by planning the purchase of raw materials with the proper price and production schedule of the goods or services to be produced. If the consumer is a wholesaler, a purchase request may be made in advance by making a market prediction about a product to be sold. If the consumer is a real user, several people can apply for a purchase within a predetermined period and purchase the desired product at a low price through joint purchase.

Description

Apparatus and method for controlling commerce between buyers and sellers over internet}

The present invention relates to an apparatus and a method for controlling a transaction between buyers and sellers on the Internet, and more particularly, a plurality of buyers and sellers on the Internet respectively present a plurality of purchase / sales conditions to autonomously execute interactive electronic commerce. It relates to an apparatus and a method which can be performed.

Conventional commerce has performed a large number of accounts and a number of conditions with a considerable time and a large number of people, but has limited the number of the number and conditions of the customer.

With the development of communication technology, telex in the past has been developed into fax, and now mobile communication and e-mail are commercialized.

The buyer or seller had to find an appropriate partner for his business, and could not easily determine whether the selected partner was an appropriate partner.

Most of the conventional technologies in the Internet e-commerce are mainly a buyer-centered reverse auction method in which the seller meets the needs of the buyer, a co-purchase method in which buyers are united with each other at a lower price, or a shopping mall method which is a seller's one-sided sale method. These methods do not take full advantage of the Internet, which has the advantage of two-way communication.

In particular, since the conventional reverse auction or co-purchase method is buyer-centered, the seller is completely dependent on the needs of the buyer, the desired unit price or quantity. As a result, if a mistake is made, the seller loses money, and the information of such a transaction is not shared with everyone who wants to use it. Therefore, a reasonable transaction cannot be made. With the emergence of numerous shopping malls, users almost accept the terms of the shopping mall operator when making a purchase. .

In other words, in the past, a very large number of buyers and sellers have not been able to present their numerous trading conditions to the other party and cannot retrieve information of various other parties and thus cannot determine the actual transaction.

Therefore, damages and inconveniences of either side of the transaction naturally occur, and no authentication is provided to the users from the operator's point of view.

Accordingly, the present invention has been proposed in view of the above-described conventional circumstances, and allows buyers on the Internet to easily find a counterpart who meets their conditions using a unified electronic document and to make a user's transaction easier. Its purpose is to provide a transaction control device and method between the seller and the seller.

It is another object of the present invention to eliminate the unnecessary distribution process for multiple or bilateral benefits, so that transactions between buyers and sellers on the Internet are made to ensure that the productivity of goods, the efficiency of services, and the appropriateness of rights are achieved for all those participating in e-commerce. The present invention provides a control apparatus and method.

It is still another object of the present invention to search and store information registered by multiple authorized sellers and multiple authorized buyers between trading parties, and within a fixed period of time, the two parties approach the terms of the other parties and autonomously adjust the requirements to make the transaction price. To provide a transaction control device and method between buyers and sellers on the Internet to determine the decision.

In order to achieve the above object, a transaction control apparatus between buyers and sellers on the Internet according to a preferred embodiment of the present invention manages purchase information including purchase conditions of a plurality of buyers, and manages the sales conditions of the plurality of sellers. Purchase control means for transmitting the selling information to the plurality of buyers;

Sales control means for managing the plurality of sales information and transmitting the plurality of purchase information to the plurality of sellers; And

And a central control means for receiving the purchase information and the sales information from the purchase control means and the sales control means and detecting the purchase information and the sales information that coincide with each other for a predetermined validity period to close the transaction.

According to a preferred embodiment of the present invention, a transaction control method between buyers and sellers on the Internet includes: a first process in which a plurality of buyers and sellers input their information for membership through a computer;

A second step in which the registered purchaser inputs purchase information through a computer;

A third step in which the registered seller inputs sales information through a computer; And

At this time, the central control system 38 issues a tax invoice and automatically reports to the tax office server 44 at a time determined as an electronic tax. The central control system 38 stores the tax return details separately when not in the reporting period, and automatically retrieves the stored details after the tax return period and receives the tax confirmation from the tax office server 44.

The transaction control method between buyers and sellers on the Internet according to an embodiment of the present invention will be described with reference to the flowchart of FIG.

In the embodiment of the present invention, membership must be registered first, and the credit of the member subscriber is authenticated.

Accordingly, a plurality of authenticated buyers retrieve a plurality of sales information provided by the purchase control system 22 through each buyer interface 10, 12, 14 and each buyer modem 16, 18, 20. (Steps 100, 120). At this time, the plurality of authorized sellers retrieve a plurality of purchase information provided by the sales control system 36 through each seller interface 24, 26, 28 and each seller modem 30, 32, 34. (Steps 110, 130).

According to such a search, the buyer selectively specifies sales information for the product he / she wants to purchase, and the purchase control system 22 stores the designated sales information (step 140). Then, the seller selectively designates the purchase information for the product that can view and sell the purchase information, and the sales control system 36 stores the designated purchase information (step 150).

Thereafter, when the buyer selects at least one of the sales information selected by the buyer, the selected sales information becomes a purchase order of the corresponding buyer and is sent to the central control system 38, and the seller selects the purchase information selected by the seller. If at least one is selected, the selected purchase information becomes a sales order of the seller and is sent to the central control system 38 ("Yes" in step 160, "Yes" in step 170).

However, if the buyer does not select the sales information selected by himself (“No” in step 160), he / she corrects and registers any sales information among the selected sales information with the desired purchase information (ie, The purchaser is willing to purchase if some modification is made to the arbitrary sales information. The modified and registered purchase information is transmitted to the purchase control system 22. The modified registered purchase information is provided for the seller to the sales control system 36 from the purchase control system 22 via the central control system 38 (steps 180 and 190).

On the other hand, if the seller does not select the purchase information selected by himself (“No” in step 170), and registers the purchase information that he / she desires with respect to any purchase information among the selected purchase information (ie, The seller is willing to sell if some modification is made to the arbitrary purchase information. The modified and registered sales information is transmitted to the sales control system 36. The modified registered sales information is provided to the purchase control system 22 from the sales control system 36 via the central control system 38 for the buyer (steps 200 and 210).

However, when the purchaser does not register the purchase information by modifying the purchase information in step 180, it is assumed that there is no more purchase intention and the operation of the purchaser side is terminated. If the seller does not register the sales information by modifying the sales information in step 200, it is assumed that there is no further sales intention and the operation of the seller is terminated.

When the buyer selects at least one of the sales information selected by the buyer in step 160 and the buyer selects at least one of the purchase information selected by the user in step 170, the central control system 38 It is checked whether the selection conditions are the same (step 220).

If the selection result of both parties is not the same ("No" in step 220), the central control system 38 determines the price according to the quantity collected within the validity period of the transaction proposed by both parties, thereby It is completed (steps 230, 240).

If the selection result of both checks is the same ("Yes" in step 220), the central control system 38 waits until the validity period of the transaction proposed by both parties and closes the transaction (step 250). If the expiration date of the transaction remains a lot, the closing time of the transaction may be advanced.

In addition, the operations from membership registration to sales and purchase execution according to an embodiment of the present invention will be described in detail with reference to the flowcharts of FIGS. 6 to 12 as follows.

For purchase or sale, users (multiple buyers and sellers) use a purchase control system via their respective interfaces 10, 12, 14, 24, 26, 28 and modems 16, 18, 20, 30, 32, 34. (22) or connect to the sales control system 36 and enter its ID and password (step 300). At this time, the ID and password are input according to an input request as illustrated in FIG. 13.

The entered ID and password are stored in the purchase control system 22 or through the respective modems 16, 18, 20, 30, 32, 34 connected to the interfaces 10, 12, 14, 24, 26, 28. The control system 36 is forwarded.

Upon receipt of the ID and password, the purchase control system 22 or the sales control system 36 retrieves the ID and password stored therein (step 310), and the currently entered ID and password are new or already registered. Check whether the operation is completed (step 320).

As a result, if it is new (No at step 320), the ID and password do not log in to the purchase control system 22 or the sales control system 36. The purchase control system 22 or the sale control system 36 which has received the password provides the member registration screen as illustrated in FIGS. 14A and 14B to the user's interface (step 330).

If the user does not register in step 330, the purchase control system 22 or the sales control system 36 provide a description of a transaction direction or a trading method of the present invention (step 340).

In spite of the above description, if there is no registration of the user, the process is terminated, and if there is an intention to register ("Yes" in steps 330 and 350), the purchase control system 22 or the sales control system 36 The screen illustrated in FIG. 13 is provided to an interface of a corresponding user to induce an input of an ID.

Thereby, when the user inputs his ID through the interface (step 360), the purchase control system 22 or the sales control system 36 which has received the ID checks whether the ID is already registered (step 360). 370) If the input ID is an ID of another user who is already subscribed or an incorrectly input ID, another ID is input again.

If the ID entered by the user is not duplicated, the purchase control system 22 or the sales control system 36 receives a password for the corresponding ID (step 380), and receives the password again (step 390).

If the second input password matches the first input password, the purchase control system 22 or the sales control system 36 may be configured as illustrated in FIGS. 15 (a) and 15 (b). Provide a screen to the user's interface. Accordingly, the user informs whether he is a supplier (ie, a seller) or a consumer (buyer), and also whether he is a corporation or an individual (steps 410 to 460). In this case, when the user wants to play a role of a supplier and a consumer at the same time, the member may be registered. In other words, a user acting as a supplier and a consumer simultaneously has two IDs.

When the user is a consumer (buyer) and an individual, the purchase control system 22 provides a screen (see FIG. 16) for registering a member to the corresponding buyer's interface. Accordingly, the buyer enters his or her personal name, social security number, bank name, account number, homepage address, address, postal code, etc. (steps 470 and 480).

If the purchaser's address currently entered is correctly entered (YES in step 490), the purchase control system 22 designates a contact person for the buyer and sends the contact person's name, phone number, fax, and email address to the buyer. (Step 500). Thereafter, the purchase control system 22 displays the terms on the buyer's interface (step 510), and if the buyer agrees to the terms on the screen as shown in Fig. 15 (c) ("Yes" in step 520). The purchase control system 22 completes the registration for the buyer, that is, the individual buyer.

When the user is a consumer (buyer) and a corporation, the purchase control system 22 provides a screen (see FIG. 16) for registering a member to the corresponding buyer's interface. Accordingly, the buyer enters his company name, business registration number, bank name, account number, homepage address, address, postal code, etc. (steps 530, 540).

If the purchaser's address currently entered is correctly entered (Yes in step 550), the purchase control system 22 designates a contact person for the buyer and sends the contact person's name, phone number, fax, and email address to the buyer. Inform (step 560). Thereafter, the purchase control system 22 displays the terms on the buyer's interface (step 570), and if the buyer agrees to the terms on the screen as shown in Fig. 15 (c) ("Yes" in step 580). The purchase control system 22 completes the registration for the buyer, that is, the buyer who is a corporation.

When the user is a supplier (seller) and a corporation, the sales control system 36 provides a screen (see FIG. 16) for registering a member to the seller's interface. Accordingly, the seller enters his company name, business registration number, bank name, account number, homepage address, address, zip code and the like (steps 590 and 600).

In the sales control system 36, if the seller's address currently entered is correctly entered (“Yes” in step 610), a contact person for the seller is designated and the name, phone number, fax, and email address of the contact person is sent to the seller. Inform (step 560). Thereafter, the sales control system 36 displays the terms on the seller's interface (step 630), and if the seller agrees to the terms on the screen as shown in Fig. 15 (c) (" Yes " at step 640). The sales control system 36 completes the registration for the seller, i.

If the user is a supplier (seller) and an individual, the sales control system 36 provides a screen (see FIG. 16) for registering a member to the seller's interface. Accordingly, the seller enters his or her personal name, social security number, bank name, account number, homepage address, address, postal code, etc. (steps 650 and 660).

In the sales control system 36, if the seller's address currently entered is correctly entered ("Yes" in step 670), a contact person for the seller is designated and the name, phone number, fax, and email address of the contact person is sent to the seller. Inform (step 680). Thereafter, the sales control system 36 displays the terms on the seller's interface (step 690), and if the seller agrees to the terms on the screen as shown in Fig. 15 (c) ("Yes" in step 700). The sales control system 36 completes the registration for the seller, that is, the seller, who is an individual.

If the ID and password entered by the user in step 320 are the same as the ID and password registered by the user in advance ("Yes" in step 320) (in this state, the user has previously registered for purchase information Or the sales control system 36 or the sales control system 36 according to the entered ID and password depending on whether the user is a supplier (seller) or a consumer (buyer). A subsequent operation is executed (step 710).

In the embodiment of the present invention, after entering the information of the consumer or the individual or the supplier of the individual or corporation, the terms and conditions are agreed, but the order may be changed.

In step 710, if the input ID and password belong to a supplier, that is, a seller, the sale control system 36 checks whether the seller wants to register a sale condition (step 720).

As a result of the check, when the seller intends to register the sale condition for the sale product, the sale control system 36 provides a screen (see FIG. 17) for registering the sale product to the interface of the seller. Accordingly, the seller may input various input items illustrated in FIG. 17 (eg, sales product name, classification by product, sales offer period, sales offer quantity, sales desired unit price, delivery period, product description, product picture, warranty period, payment condition, In the return period, product advertisement, etc., desired sales conditions are input (step 730). Here, n choices are input for the sales offer period, the sales offer quantity, the desired sale price, and the delivery period.

The sale conditions input for one sale product are stored in the data storage unit 36f of the sale control system 36 as sale information (step 740). The sales control system 36 transmits the sales information to the central control system 38 so that the buyer can retrieve the sales information through the purchase control system 22.

On the other hand, the seller can determine their own sales conditions by looking at the purchase information of the buyers without registering the sales conditions immediately in step 720. In this case, the seller first inputs information about the product he wants to sell. That is, the sales control system 36 provides a screen as illustrated in FIG. 18 to the seller's interface, and the seller sells information (eg, information about a product he wants to sell on the screen displayed on the interface). Enter the category (Sporting Goods), Product Name (MTB Bicycle), Buyer (Gangnam Health), Manufacturer (Samcheonri), Similar Products (Bike), Sales Period, etc.

Then, when the seller clicks a desired part in the clickable area (eg, product classification search, product search, buyer search, manufacturer search, and similar product search) on the screen illustrated in FIG. 18, the sales control system 36 provides a screen as illustrated in FIG. 19 to the merchant's interface (step 750). FIG. 19 illustrates that there are three pieces of information that the seller wants to purchase for the sale product to be sold, and the retrieved number may be different.

Thereafter, when the seller clicks "Yes" on the item "Do you want to store the purchase information" on the screen provided in the sales control system 36 (see FIG. 20), the sales control system 36 may display the above information. The retrieved information is stored as purchase information (step 760). At this time, the quantity so far applied for the sale of the product of the purchase information is displayed together. In FIG. 20, four or more display areas corresponding to the item of "Quantity applied for sale" are displayed differently from the other display areas by color or constant display, but one display area instead of four display areas. Can be displayed directly.

The seller then selects a desired sales method (ie, sales information) (step 770). That is, by looking at the purchase information illustrated on the screen of Figure 20 will be presented his selling method for the product. For example, in FIG. 20, when the seller clicks "Selection 2", the period for recruitment of the purchased product is until March 25, and if the quantity of products recruited for the purchased product is 5 within this period, the purchased product The selling price for is 170,000 won, and if the quantity collected for the purchased product is 150, the selling price for the purchased product is 110,000 won.

Accordingly, the sales control system 36 checks whether any of the purchase information stored therein matches the sales information (step 780).

If there is information that matches each other as a result of the check ("Yes" in step 780), the sales control system 36 stores the matching information as transaction information with which the transaction is concluded (step 790), and stores the transaction information in the central control system. Transfer to step 38 (step 800). When the transaction is concluded, the purchase control system 22 knows the transaction conclusion through the communication network 40 and transmits the transaction information to which the transaction is concluded to the central control system 38.

The sales control system 36 checks whether the payment has been deposited from the central control system 38 (step 810), and if the payment is confirmed to be deposited (see FIG. 21), stores the payment history and the above. After the delivery instruction (delivery instruction) information from the central control system 38 is stored, the delivery instruction information is transmitted to the interface of the seller through the seller's modem of the seller (step 820). The central control system 38 then provides the purchase control system 22 with information that the goods will be delivered.

The seller then delivers the product targeted for the closing of the transaction to the corresponding buyer within the valid period of the transaction information. The seller then connects to the sales control system 36 via the seller interface and the seller modem and then bills the central control system 38. The central control system 38 pays the sales control system 36 upon receipt of the inspection result and payment approval that there is no problem with the goods delivered from the purchase control system 22.

In step 810, the sales control system 36, if the seller wants to retrieve the purchase information again without checking the payment history ("No" in step 810) ("Yes" in step 830) to the step 750 The operation resumes from that step.

If the selling method selected in step 780 does not match the purchase information, the selling control system 36 proceeds to step 840 to check whether there is a sale change registration. The sale change registration is used when the seller wants a trade condition other than the buyer's suggested condition to display the condition presented by the buyer on the seller's interface and then reverse the proposal. In this case, the buyer may receive the reverse offer and accept it, or the buyer may again offer the offer to the seller. After several repeated negotiations between the buyer and the seller, if the conditions are mutually agreed, the purchase control system 22 and the sale control system 36 consider the transaction to be closed.

The sale change registration may be modified when the seller clicks "sell method registration" in FIG. 20 or 22. Of course, the above "sales method registration" is also used when entering the desired sales method at the beginning.

If the sale change registration is not performed in step 840, the sale control system 36 waits until the transaction is closed or the predetermined validity period (step 850).

Then, in step 840, when the seller clicks the "sell method registration" to change the initially registered sales information (see FIG. 23) (step 860), the sales control system 36 stores the changed sales information ( In step 870, the changed sales information is transmitted to the central control system 38. Thereafter, the sales control system 36 returns to step 750 to allow the seller to retrieve the purchase information.

On the other hand, if the user who registers the ID and password in advance in step 710 is the consumer (ie, the buyer), the purchase control system 22 checks whether the buyer wants to register the purchase condition (step 880).

As a result of the check, when the buyer wants to register the purchase condition for the purchased product, the purchase control system 22 provides a screen (see FIG. 24) for registering the purchased product to the interface of the buyer. Accordingly, the buyer can enter the various input items illustrated in FIG. 24 (for example, purchase product name, product classification, purchase offer period, purchase offer quantity, purchase desired unit price, delivery period, product description, product picture, warranty period, payment condition, The desired purchase condition is inputted in the delivery condition, the warranty condition, the purchase advertisement, etc. (step 890). Here, n selections are input for the purchase offer period, the purchase offer quantity, the desired purchase price, and the delivery period.

The purchase conditions input for one purchase product are stored in the data storage 22f of the purchase control system 22 as purchase information (step 900). The purchase control system 22 transmits the purchase information to the central control system 38 so that the seller can retrieve the purchase information through the sales control system 36.

On the other hand, the buyer can determine the purchase conditions by looking at the sales information of the sellers without registering the purchase conditions immediately in step 720. In this case, the buyer first inputs information about the product he / she wants to purchase. That is, the purchase control system 22 provides a screen as illustrated in FIG. 25 to the corresponding buyer's interface, and the corresponding buyer's information about the product he / she wants to purchase on the screen displayed on the interface (for example, Enter the classification (sports goods), product name (MTB bike), seller (Gangnam Health), manufacturer (Samchully), similar product (bike), purchase period, etc. for the product you want to purchase.

Then, when the buyer clicks a desired part in the clickable area (eg, product classification search, product search, seller search, manufacturer search, and similar product search) on the screen illustrated in FIG. 25, the purchase control system 22 provides a screen as illustrated in FIG. 26 to the seller's interface (step 910). FIG. 26 illustrates that there are three pieces of information that the seller wants to purchase for the sale product to be sold, and the retrieved number may be different.

Thereafter, when the buyer clicks "Yes" on the item "Do you want to store the sales information" on the screen provided in the purchase control system 22 (refer to FIG. 27), the purchase control system 22 may select the The retrieved information is stored as sales information (step 920). At this time, the quantity up to the present that applied for the purchase of the merchandise of the sales information is displayed together. In FIG. 27, four or more display areas corresponding to the item of "Quantity applied for sale" are displayed differently from the other display areas by color or constant display, but one display area instead of four display areas. Can be displayed directly.

Then, the buyer selects a desired purchase method (ie, purchase information) (step 930). That is, by looking at the sales information illustrated on the screen of Figure 27 will present their own purchase method for the product. For example, in Fig. 27, when the seller clicks on "Selection 2", the offer period for the sale product is until March 31, and if there are five items collected for the sale product within this period, the sale product The purchase price for the product is 200,000 won, and if the quantity collected for the product is 150, the purchase price for the product is 120,000 won.

Accordingly, the purchase control system 22 checks which of the sale information stored therein matches the purchase method based on the purchase method selected by the buyer (step 940).

If there is information that matches each other as a result of the check ("Yes" in step 940), the purchase control system 22 stores the matched information as transaction information with which the transaction is concluded (step 950), and stores the transaction information in the central control system. To 38 (step 960). At this time, the purchaser sends information (such as FIG. 28) on whether to pay the item for purchase by the credit card or online to the purchase control system 22, and the purchase control system 22 sends the purchaser. Stores credit card information. When the transaction is concluded, the sales control system 36 knows the transaction conclusion through the communication network 40 and transmits the transaction information to which the transaction is concluded to the central control system 38.

Thereafter, the purchase control system 22 requests the central control system 38 to inquire about the credit card information of the buyer stored therein when the buyer wants to pay the credit card (YES in step 970). (Steps 980, 990). The central control system 38 makes a credit request for the credit card to the credit bureau server 46 and transmits the result to the purchase control system 22.

The purchase control system 22 enables the purchaser to pay by the buyer's credit card if the credit card is authorized, and if the credit card is not authorized ("No" in step 1000). Will send a message to the buyer's interface as to whether the online payment is possible.

Accordingly, when the buyer selects the online payment, the purchase control system 22 processes the online purchase of the purchase goods of the buyer.

However, in step 1010, the purchase control system 22 returns to step 910 if the buyer does not want to make an online payment and tries to retrieve the sales information again (Yes in step 1020). Start over.

If the purchase method selected in step 940 does not match the sales information, the purchase control system 22 proceeds to step 1030 to check whether there is a purchase change registration. The purchase change registration is used when the buyer wants a trade condition other than the seller's proposed condition and then displays the seller's proposed condition on the buyer's interface and then reverses the buyer's desired terms. In this case, the seller may accept and accept the reverse offer, and the seller may again offer the reverse offer to the buyer. After several repeated negotiations between the buyer and the seller, if the conditions are mutually agreed, the purchase control system 22 and the sale control system 36 consider the transaction to be closed.

The purchase change registration may be modified when the buyer clicks on "purchasing method registration" in FIG. 27 or FIG. 29. Of course, the above "purchasing method registration" is also used when entering the desired purchase method initially.

If the purchase change registration is not performed in step 1030, the purchase control system 22 waits until the transaction is closed or a predetermined validity period (step 1040).

If the purchaser changes the purchase information initially registered by clicking the "purchase method registration" in step 1030 (step 1050), the purchase control system 22 stores the changed purchase information (step 1060), The changed purchase information is transmitted to the central control system 38. The purchase control system 22 then returns to step 910 to allow the buyer to retrieve the sales information.

On the other hand, after the transaction between the buyer and the seller is completed, the operation until the end of the predetermined validity period is extended with reference to the flowchart of Figure 30 as follows.

The central control system 38 stores the expiration date end data (step 1110) when the expiration date between the purchase information and the sales information for which the transaction is completed ("Yes" in step 1100) (step 1110) and inquires about the extension of the expiration date. The data is sent through the purchase control system 22 and the sales control system 36 to the successful parties (ie, buyer and seller) (step 1120).

As a result, the central control system 38 extends the validity period (step 1140) if both the buyer and the seller have received the data requesting the extension of validity ("Yes" in step 1130). The extension date shall be the extension date described in the above-mentioned extension inquiry data.

If any of the buyers and sellers who received the data requesting the extension of the validity do not allow the information (ie, the purchase information or the sales information) of the person who did not allow the extension of the validity (eg, the buyer or seller), Delete it.

The article delivery, return, and payment method according to the present invention will be described with reference to the flowchart of FIG. 31 as follows.

Once a transaction is closed between the buyer and the seller, the transaction closing information is stored in the central control system 38.

Thereafter, the purchaser receives a predetermined down payment and a payment to the operator who operates the central control system 38 (step 1200).

At this time, if the operator does not complete the storage ("No" in step 1210), the operator is urged to pay the payment (step 1220), and if the buyer gives up the storage ("Yes" in step 1230) The operator imposes some sanctions as the buyer violated the transaction (step 1240).

If the purchaser has received the payment in step 1210, the process proceeds to step 1250, and the operator instructs the seller to deliver the purchased goods of the buyer. Accordingly, the seller delivers the sales item corresponding to the purchased item to the buyer and the buyer inspects the delivered item (step 1260).

As a result of the inspection of step 1260, if the buyer does not have a return intention (“No” in step 1270), the seller charges the operator (step 1280), and the operator pays the seller ( Step 1290).

As a result of the inspection of step 1260, if the buyer returns the goods despite the defect of the goods (“No” in step 1300), the shipping fee is the responsibility of the buyer and the down payment paid by the buyer limits the operator's fee. (Step 1310) The seller is paid and the contract is destroyed. In this case, the balance other than the down payment (ie, the price) is returned to the corresponding buyer (steps 1320 and 1330).

On the other hand, if the cause of the return is a fault of a good, service or right, the buyer is repaid at the seller's expense ("Yes" in step 1340).

As a result of the inspection of step 1260, if the seller returns the goods due to the defect of goods, services, or rights, the seller does not re-deliver the goods within the contracted period of the normal delivery to the buyer (in step 1340). "No") The operator stops now paying the item to the seller (step 1350) and refunds the down payment and payment to the buyer (step 1360). The operator then sanctions the seller (step 1370).

And, the tax treatment method according to the present invention will be described with reference to the flowchart of FIG.

When the transaction is closed, the central control system 38 issues a tax invoice according to the transaction completion (step 1410) and stores the tax invoice for each customer (step 1420).

Thereafter, the central control system 38 acts as an electronic tax return to the tax office server 44 when the tax return period arrives ("Yes" in step 1430) (step 1440), but when the tax return period does not arrive. (No in step 1430) The tax return details are stored (step 1450).

According to the present invention as described above, since each supplier receives an order according to the sales period, it is possible to predict the sales volume and the selling price. In this case, if the seller is a producer, the cost can be reduced through planned production, so that the seller can sell to the consumer at a lower price. If the seller is a wholesaler, a planned purchase can be made from the producer for efficient inventory management. If the consumer is a producer, the cost can be reduced by planning the purchase of raw materials with the proper price and production schedule of the goods or services to be produced. If the consumer is a wholesaler, a purchase request may be made in advance by making a market prediction about a product to be sold. If the consumer is a real user, several people can apply for a purchase within a predetermined period and purchase the desired product at a low price through joint purchase.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
