purchasing agent sends one copy to the supplier, one
copy to the AP department, where it is filed temporarily,
and files the third copy in the purchasing
department.
When the goods are received, the receiving department
inspects and verifies them using the packing
slip, which is attached to the goods. The receiving
clerk manually prepares two hard copies of a receiving
report. One copy accompanies the goods to the warehouse
for storage. The receiving clerk sends the second
copy to the purchasing agent, who uses it to update the
inventory subsidiary ledger and close the open purchase
order. The purchase agent then files the receiving
report in the department.
Accounts Payable and Cash Disbursements
Procedures
The accounts payable clerk receives the supplier’s invoice
and reconciles it with the purchase order in the
temporary file. From her computer terminal, the clerk
records the purchase in the purchases journal and
records the liability by creating a cash disbursement
voucher. The clerk then updates the inventory control
and accounts payable control accounts in the general
ledger. The purchases order and invoice are then filed
in the department.
Each day, the clerk visually searches the cash disbursements
voucher file from her terminal for open
invoices that are due to be paid. From her computer
terminal, the clerk prepares the check and records it in
the check register. The negotiable portion of the check
is mailed to the vendor, and a check copy is filed. The
clerk then closes the voucher register and updates the
accounts payable control and cash accounts in the general
ledger.
