SoftData, a vendor, sends an invoice to Creative Company for data warehousing support services. The invoice is sent directly to Michael, the accounts payable clerk, who manually records the invoice in the accounts payable subsidiary ledger. Once the invoice is recorded, it is forwarded to Sam, the cash disbursements clerk, for processing. Sam prepares a check to pay the invoice and sends the check and invoice to Jef, the company treasurer. Jef approves and signs the check and cancels the invoice. Jef then mails the check to SoftData and returns the cancelled invoice to Sam for recording in the cash disbursements journal and filing. Once a week, Michael posts disbursements from the cash disbursements journal to the accounts payable subsidiary ledger. Michael prepare the cash disbursement report for the management at the end of each month.
