Prospect Corporation, your new audit client, processes its sales and cash receipts in the follow- ing manner: (1) Sales. Salesclerks prepare sales invoices in triplicate. The original and second copy are pre- sented to the cashier, and the third copy is retained by the sales clerk in the sales book. When the sale is for cash, the customer pays the sales clerk, who presents the money to the cashier with the invoice copies. A credit sale is approved by the cashier from an approved credit list. After receiving the cash or approving the invoice, the cashier validates the original copy of the sales invoice and gives it to the customer. At the end of each day, the cashier recaps the sales and cash received, ?les the recap by date, and forwards the cash and the second copy of all sales invoices to the accounts receivable clerk. The accounts receivable clerk balances the cash received with cash sales invoices and prepares a daily sales summary. Cash sales are posted by the accounts receivable clerk to the cash receipts journal, and the daily sales summary is ?led by date. Cash from cash sales is included in the daily bank deposit (preparation of the bank deposit is described with cash receipts in the following section). The accounts receivable clerk posts credit sales invoices to the accounts receivable ledger and then sends all invoices to the inventory control clerk in the sales department. The inventory clerk posts to the inventory control cards and ?les the sales invoices numerically. (2) Cash receipts. The mail is opened each morning by a mail clerk in the sales department.
