A copy of the P.S. is sent by the warehouse to the accounts receivable department.

The invoices include information regarding the products delivered (quantity, unit price, etc.) and the total amount that the customer has to pay. The P.S. is annotated with the invoice information. The annotated P.S. and a second copy of the invoice are sent to another clerk who updates the customer's balance in the customer file. The annotated P.S. and invoice copy are then filed. When the customer sends payment to the accounts receivable department, a clerk verifies the amount owed and the amount paid by checking the corresponding invoices (from the invoice file). If a discrepancy is found between the amount owed and the amount paid, the customer is informed accordingly. The payment entry is made to account in the general ledger.
