Abstract: An electronic procurement system connected to a network enables employees of an organization to electronically order goods directly from vendors. The system includes an electronic memory storing a vendor's catalog of items available for purchase, a transmitter, operatively connected to the network and to an external network, for electronically transmitting a purchase order from the system to a vendor via the external network, and a comparison unit. A record of the purchase order is stored in the memory of the system and the comparison unit compares an invoice received from the vendor with the record to determine whether there are any discrepancies.
