The cash register prints a sales receipt that shows the total ,any discounts,the sales tax,and the grand total. The salesperson collects payment from the customer,gives the receipt to the cus-tomer,and either directs the customer to the warehouse to obtain the items purchased or makes arrangements with the shipping department for delivery. The salesperson is responsible for using the system to determine whether credit card sales are approved and for approving both credit sales and sales paid by check. Sales returns are handled in exactly the reverse manner, with the salesperson issuing a return slip when necessary .
