METHOD FOR MANAGING BUYER TRANSACTIONS AND SETTLEMENTS USING COMMUNICATION NETWORK BETWEEN COMPUTERS, AND METHOD FOR RELAYING INFORMATION FOLLOWING BUYER CONSUMPTION TRENDS TO THE BUYER

摘要

Described herein are methods and apparatus for the processing of electronic invoices. A server for processing invoices communicates with computing systems such as a supplier system (used by a supplier), a buyer system (used by a buyer), and finance systems (which manage bank accounts of the supplier and buyer). The server communicates with the supplier system and the buyer system regarding an electronic invoice that relates to a transaction between the supplier and the buyer, and that includes a unique identification code. When the buyer has approved the electronic invoice, the supplier system and/or the server is able to settle the invoice using the unique identification code.
