Publication number: 20020188524Abstract: A method of an order-maker placing an order and an order-receiver receiving the order, realized in an environment where electronic mail is available. The order-maker stores product-order information in an electronic mail attachment file, converts the file into a predetermined language format, and sends the file to the order-receiver. The order-receiver re-converts the received electronic mail attachment file to extract the order data, allocates the order, and instructs delivery. Also, an order condition may be set such that approval by an approving-user is needed for all orders or only for orders of a certain amount of money or more. A previously registered order-maker can register an additional order-maker to enable ordering for a plurality of users, thereby making it easy for purchase budget control, etc. and making it possible to re-order using the previous order history.Type: ApplicationFiled: April 17, 2002Publication date: December 12, 2002Inventor: Hidetaka Shimizu
