Customer checks are received via mail in the Cash Receipts department. The cash receipts clerk prepares a remittance list and a deposit slip. The remittance list is forwarded to the Accounts Receivable department and the customer checks and deposit slip are forwarded to the Treasurer. In Accounts Receivable the remittance list is used to update customers' account balances and an Accounts Receivable Aging report is prepared which is forwarded to the Controller. The remittance list is then filed by date in Accounts Receivable. In the Treasurer's department the Treasurer endorses the checks and takes the deposit slip and checks to the bank.
