Ms. Hanan has asked you to document the Accounts Receivable system at HAPPY Company. Ms. Hanan's narrative of the system follows: When checks are received as payment for accounts due, a remittance slip is included with the payment. The Treasurer sends this to accounts receivable clerks and she will enter the data in the system. Data from the remittance slips are entered into the computer, and the accounts receivable database is updated. The remittance slips are stored in a file drawer by date. When credit sales occurred, the sales clerk will update the Accounts Receivable. The customer also can make online payment and the system will update this information automatically. Every week, accounts receivable system generates a cash receipts report and an aged trial balance using the accounts receivable ledger. The cash receipts report is sent to Mr. Ahmad and Ms. Mona for them to reviews it. A copy of the aged trial balance is sent to the credit and collections department, where it is reviewed. Required: Prepare the context diagram and level 0 DFD to depict the Accounts Receivable system in HAPPY Company
