This guide takes one sale from the first product to the receipt. For a paper receipt, you need a receipt printer attached to the till.

## Steps

1. **Add the products.** Scan the barcode, or type part of the name or code, in the one box. An exact barcode, SKU or code adds the product straight away. Anything else opens a list, and you pick the product the customer means.

2. **Take the payment.** Type the amount the customer hands over, and the change due shows as you type. Change is given on cash only. For a customer who pays in more than one way, add a payment line for each way.

3. **Print the receipt.** When the sale is finished, the completion step offers **Print receipt**. Choose it, and the slip comes out of the printer for the customer. A shop set to always print its receipt still prints it before this step.

## Paying in more than one way

Add a payment line for each way the customer pays, each with its own amount. After each line, the screen shows what is still to pay. You can remove a line before you confirm, and no record is written until then.

The sale is confirmed only when nothing is left to pay. It keeps one number throughout.

An over-payment on account does not become customer credit.

## If something goes wrong

- If no receipt printer is attached, the **Print receipt** row says *No printer attached* and cannot be used.
