Customer payments come into the mail room where mail clerks open the envelopes and send the checks and remittance advices to the accounts payable department. The AR clerk reconciles the remittance advice with the check and updates the customer’s account in the digital AR subsidiary ledger. The clerk then files the remittance advices in the department and sends the checks to the cash receipts department. As previously mentioned, at the end of the day, the AR clerk prints a hard-copy AR summary from the department personal computer and sends it to the general ledger department
