A customer comes into the store and selects items to be purchased and presents them at
the desk. The sales assistant types in the codes of the stock items into the computer and
these stock codes are used to present the rest of the stock item's details to the assistant.
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. In this case Invoices are sent out to customers at
the end of the month. The Security guards receipts are checked off against the recorded
credit sales for that day at the close of business by the sales manager.
