The salesperson prepares four copies of a sales invoice, retaining one and sending three to the cashier. The cashier approves and processes the sale by assigning it a consecutive number and recording it in the cash register. The cashier sends the cash register tape to the assistant manager, who also has a copy of the validated invoice. The assistant manager uses the validated invoices, cash receipts and slips for return merchandise to prepare the bank deposit. The manager reviews the bank deposit and takes it to the bank. The manager also files the bank deposit documents by date. The assistant manager uses the cash register tape to prepare a report, which he reconciles with the other documents in his possession.
