Question

Big is a major manufacturer of automobiles. This narrative describes the purchasing, accounts payable and cash disbursement process for original equipment windshields for its only supplier of windshields, Glass.

Bag’s inventory system requests the purchasing department to reorder windshields. When the PO is created a record is added to the PO file (all data is stored on magnetic disks) and an electronic transmission is sent to Glass. Glass acknowledges the order (also electronically).

Glass ships the order and sends an electronic invoice to Big. The electronic invoice data is recorded to a pending invoices file.

When the goods arrive at Big’s warehouse, a receiving clerk examines the goods and keys in the receiving data. The keying operation creates a receiving record on the receiving file and updates the PO record to reflect the receipt.

Each morning, the AP clerk accesses the pending invoices file to identify invoices for which there are receiving reports and POs. The computer matches the invoice data to the PO and receiving data and displays them to the clerk. If the data does not match the clerk follows up with Glass to resolve discrepancies. If the data matches, the clerk enters the date the invoice should be paid and an authorization code for the bank to transfer payment to Glass on that date. The payment authorization is encrypted and transmitted electronically to Big’s bank where it is stored until the payment date.
