The AP clerk periodically reviews the open AP file for liabilities that are due. To maximize returns on invested cash, yet still take advantage of vendor discounts, the clerk will pull the invoice two days before its applicable due date. Upon finding an open accounts payable file in need of payment, the clerk manually prepares a check for the amount due as per the invoice. The hard copy AP ledger is also updated by the AP clerk. The check number, dollar amount, and other pertinent data are manually recorded in the hard-copy check register. The check is then sent to the cash disbursements department. Finally, the invoice is discarded, as it no longer has any relevant information that hasn’t already been recorded elsewhere.
