An Electronic Commerce system enables corporate purchasers and suppliers to electronically transact for the purchase and supply of goods/services. The system includes three major hardware and software components: buyer, supplier and bank/administration. To enable suppliers to supply goods and services online and process electronic orders, several software components are used for operating a supplier processor server and a supplier catalog server. To enable corporate purchasers to purchase products and services online, preferably over the Internet, from suppliers, software is used for operating a customer server to which multiple users may log-on and access the supplier server. An Automated Clearing House (ACH) server may be used to interface with a bank's (ACH) systems. A service bureau that supplies the hardware and/or software components and assists to administer the system includes a transaction counter, which records transactions and charges the buyers and/or suppliers based on the number of purchase orders and/or invoices issued.
Although the present invention has been described in relation to particular embodiments thereof, many other variations, modifications and other uses will become apparent in those skilled in the art. It is preferred that the present intention be limited not by the specific disclosure herein, but by the scope of the appended claims.
