The assistant also types in the quantities of each item being purchased and the type of Sale ( credit or Cash ). If it is a cash sale the system produces an Invoice for the customer. The customer brings the invoice to the Cashier. The cashier types in the invoice number, the invoice details are printed on the screen, and the cashier types in the amount paid into the computer system. The customer keeps two copies of the printed invoice. One of which is given to the security guard on the way out and the other is kept as a receipt for the customer. The Security guards receipts are checked off against the recorded cash sales for that day at the close of business by the sales manager. If the sale is a credit sale, the attendant types in the Customer Id of the customer, the system does a credit check on the customer’s record in the customer master file and the total of all sales owing in the sales file.
