Suppose that you had your internship at a private company where its management asked you to help in documenting the major business information flows. You held interviews with cash receipts clerks trying to understand the cash receipts system at the company. The following paragraphs summarize the narratives of the system:

Customer payments include cash received at the time of purchase and account payments received in the mail. At the end of the day, the treasurer endorses all checks and prepares a deposit slip for the checks and the cash. A clerk then deposits the checks, cash, and deposit slip at the local bank each day. When checks are received as payment for accounts due, a remittance slip is included with the payment. The remittance slips are used to update the accounts receivables file at the end of the day. The remittance slips are stored in a file and sorted by date.

Every week, a cash receipts report and aged trial balance are generated from the data in the accounts receivable ledger. The cash receipts report is sent to the management. A copy of the aged trial balance by customer account is sent to the credit department.
