The following paragraph describes the manual procedures for the purchase order process and cash disbursement process. The inventory control clerk examines the inventory records for items that must be replenished and fill in a two-copies purchase requisition form. The first copy of the form is sent to the purchasing department, and the second copy is filed. Upon receipt of the requisition form, the purchasing clerk selects a supplier from the valid vendor file and prepares a three-copies purchase order. The first copy is sent to the supplier, second copy is sent to the Accounts Payable (AP) department where it is filed temporarily, and the third copy is filed in the purchasing department. A few days after the supplier ships the order, the goods arrive at the receiving department. They are inspected, and the receiving clerk prepares a three part receiving report describing the number and quality of the items received. First copy of the receiving report accompanies the goods to the stores, where they are secured. Second copy is sent to inventory control, where the clerk posts it to the inventory records and files the document. Third copy is sent to the AP department, where it is filed with the purchase order. A day or two later, the AP clerk receives the suppliers invoice for the items shipped. The clerk pulls the purchase order and receiving report from the temporary file and compares the quantity ordered, quantity received, and the price charged on suppliers invoice. After reconciling the three documents, the clerk enters the purchase in the purchases journal and posts the amount owed to the AP subsidiary account. On the payment due date, the AP clerk posts to the AP subsidiary account to remove the liability and prepares a voucher authorizing payment to the vendor. The voucher is then sent to the cash disbursements clerk. Upon receipt of the voucher, the cash disbursements clerk prepares a cheque and sends it to the supplier. The clerk records the cheque in the cheque register and files a copy of the cheque in the department filing cabinet.
