The overall operation of the present invention configured as described above will be described with reference to FIGS. 7 and 8.

First, FIG. 7 is a flowchart illustrating a case where a buyer of country A purchases goods of country B according to an embodiment of the present invention.

As shown, in the case where the buyer 32 of station A 30 purchases the seller 41 of the station B 40, that is, the goods, the buyer 32 of the station A uses the server via the Internet. The server 10 and the partner company server 20 are connected. The product purchase condition is input with reference to the content provided in the content 11 of the main server 10 (step 701). The partner server 33 of the country supports the EDI (step 702). When the purchase application registration is received in the main server 10 (step 703), the main server 10 searches the DB 12 for the relevant seller. (Producer) is searched, and a search list is prepared accordingly (step 704). Then, the list is sent to the partner company 43 server (step 705) and the seller is sent by mail (step 708). The partner country B server 43 sends the promotional material according to the list transmission to the seller B of the station B (step 706). Accordingly, the seller 41 of the country B reviews the conditions and inputs the auction conditions (steps 707 and 709).

The seller's auction conditions operate the reverse auction system of the optimized trading system 13 of the main server 10 through the EDI support of the partner (steps 710 and 711). If the condition evaluation and the optimal condition are selected by the operation of the reverse auction system (step 712), the evaluation result is provided (step 714), and at the same time, the buyer of the country A (32) through negotiation support of the server A of the partner country A (33). ) Review the evaluation data (steps 713 and 715). Accordingly, the purchaser 32 of the country A transmits the contract terms to the main server 10 through negotiation arbitration of the partner server 33 (steps 716 and 717), and the main server 10 transmits the contract B. Negotiation is mediated through the partner server 43 of the country and sent to the seller 41 (steps 718 and 719). Therefore, the seller 41 of the B country examines the contract terms (step 720), and when the contract is determined (step 721), concludes a contract with the main server 10 and establishes a production plan (722, Step 723).

On the other hand, the purchaser 32 of the country A plans to sell when the contract is concluded through the main server 10 (step 724), and transmits the conditions according to the object acquisition to the partner server 33 (step 725). ), The partner server 33 organizes the logistics conditions and sends them to the main server 10 (step 726), the main server 10 performs the logistics, insurance and customs clearance management partner server 43 of the B country Notify the seller 41 of the shipping conditions through the steps 727 and 728. Therefore, the seller 41 of the country B produces and ships the goods, and notifies the main server 10 of them (steps 729 and 730). The main server 10 performs logistics management (step 731), requests the buyer 32 to take over and pay the goods through the partner country server 33 (step 732), and the buyer 32 supplies the goods. After the acquisition and inspection (step 733), the money is transferred to the partner server 33 in the currency of the home country A (step 734).

When the payment is confirmed to the partner server 33 of the A country, the main server 10 performs the accounting management, so that the payment is paid to the seller 41 through the partner server 43 of the B country ( Steps 735,736,737). In some cases, the sale price may be paid immediately by the seller's supplier after shipment. The seller 41 of State B receives the payment in the currency of State B, terminates the transaction, and establishes an A / S plan (steps 738, 739, 740). The A / S plan of the seller 41 is supervised by the partner server 43, the main server 10 is comprehensively managed, and supports the A / S to the partner server 33 of the A country (741, 742, 743). ). A / S support of the partner server 33 supports the sale of the buyer 32 of the A country (step 744).

In addition, the main server 10 performs the accounting process (step 746), and ends the accounting by sending the offset amount to the quarterly transaction to each partner server 33 (43) (step 746, 747, 748).

8 is a flowchart illustrating a case in which a product of country A is sold to a buyer of country B according to an embodiment of the present invention.

As shown, when the seller 31 of station A 30, i.e., sells the goods to the purchaser 41 of station B 40, the buyer 32 of station A is responsible for maintaining the server via the Internet. The server 10 and the partner company server 20 are connected. The product information and the sales condition are input with reference to the contents provided in the content 11 of the main server 10 (step 801). The partner server 33 of the country supports the EDI and the electronic catalog (step 802). When the product sales application registration is received in the DB 12 of the main server 10 (step 803), the main server 10 receives the DB. Search (12) to search for relevant buyers and create a search list accordingly (step 804). Then, the list is notified to the partner server 43 (step 805) and the mail is sent for each buyer (step 806). The partner server 43 sends the promotional material according to the list sending to the purchaser 42 (step 807). Accordingly, the purchaser 42 of the country B reviews the conditions and inputs the purchase conditions (steps 808 and 809).

The seller's auction conditions operate the auction system of the optimized trading system 13 of the main server 10 through the partner's EDI (steps 810 and 811). When the condition evaluation and the optimal condition are selected by the operation of the auction system (step 812), the evaluation results are provided (step 815), and at the same time, the seller of the country A through the negotiation support of the partner company server 33 of the country A (31). ) Review the evaluation data (steps 813, 814). Therefore, the seller 31 of the station A sends the contract terms to the main server 10 through the negotiation arbitration of the partner server 33 (steps 816 and 817), and the main server 10 transmits the contract to the station B. Negotiate and mediate through the partner server 43 of the buyer 42 and send (step 818, 819). Accordingly, the purchaser 42 of the B country reviews the contract terms (step 820), and when the contract is determined (step 821), concludes a contract with the main server 10 and establishes a sales plan (822, 823). step).

On the other hand, the seller 31 of the country A produces a product when the contract is concluded through the main server 10 (step 824), the buyer 42 of the country B after the establishment of a sales plan, take over the goods When sending the conditions according to the partner server 43 (step 825), the partner server 43 summarizes the logistic conditions and sends to the main server 10 (step 826), the main server 10 is a logistics, Insurance and customs management is carried out to notify the seller 31 of the country A shipping conditions through the partner server 43 of the country B (steps 827 and 828). Therefore, the seller 31 of the station A ships the goods and notifies the main server 10 of them (steps 829 and 830). The main server 10 performs logistics management (step 831), requests the buyer 42 to take over and pay the goods through the partner country server 43 (step 832), and the buyer 42 supplies the goods. After the acquisition and inspection (step 833), the money is transferred to the partner server 43 in the currency of the own country B (step 834), the transaction is terminated, and the sale is performed (step 839, 844). When the main server 10 confirms the payment to the partner server 43 of the country B (step 835), the accounting management is performed, and the price is paid to the seller 31 through the partner server 33 of the country A. (Step 836,837). In this case, the seller may pay the selling price immediately after the seller ships the goods. The seller 31 of State A receives the money in the currency of State A and establishes an after-sales plan (steps 838,840). The A / S plan of the seller 31 is supervised by the partner server 33, the main server 10 is comprehensively managed, and supports the A / S to the partner server 43 of the B country (steps 841, 842, 843). ). A / S support of the partner server 43 supports the sale of the buyer 42 of the B country (step 844).

In addition, the main server 10 performs the accounting process (step 845), and the accounting ends by remitting the offset amount to the transaction according to the transaction during the quarterly period to each partner server 33 (43). (Steps 846,847,848).

As described above, the present invention provides the cost of the bank transaction, such as opening a letter of credit (LC), remittance, and exchange transaction (because remittance, exchange transaction, etc. are generated only once in a certain period such as quarter and half) and exchange profit or loss. The burden is much less effective.

On the other hand, producers can receive payments from their suppliers in their local currency immediately after shipment, and buyers can make a transaction based on trust by acquiring goods to their partners in their local currency or after the purchase.

In addition, buyers and sellers pay the intermediate margins saved by direct transactions by buying at the lowest price by auctioner at the price that the seller wants to receive, and the buyer at the lowest price by auction. And it is a useful invention that can be returned to both the end consumer and the practical benefit, and can be satisfied by all three.
