If you are starting a business that sells items to the public, you will need to use a cash register. A cash register records each sale that is made throughout the day. For each transaction on the register, you place any cash or checks received in the machine's cash drawer to keep them safe. Cash register machines are available in a wide variety of models, but each offers the same basic functionality.
Power on the register by turning the register key to the "REG" position. This gets the register ready for sales.
Press the corresponding number keys for the amount of the first item that you want to ring up. You don't have to enter in decimal points. For instance, if the item is £3, you enter in "500." Press the "DEPARTMENT 1" key after you get the price entered. Repeat this process for each item you need to ring up.
Subtotal the purchase by pressing the "SUBTOTAL" button. If you are charging sales tax, you can use the "SUBTOTAL/W/TAX" button.
Enter in the amount of cash you are given by the customer and press the "AMT TEND/TOTAL" button. Any change due will be displayed on your screen and the cash drawer will open. For check or charge payment, press either the "CHECK" or "CHARGE" button without entering in the amount.
Close the cash drawer and tear off the receipt that has printed from the register printer. Give the customer the receipt.
