You can find a customer at any time before tendering a sale, though it is probably best to find customers at the start of any sale. If you want or need to find a customer, please do the following...
Note:
If the store administrator has set the Register parameter to call up the Find Customer screen automatically, then the Find Customer screen will appear at the start of each sale. To exit out of the Find Customer screen, you can simply press the Esc key.
Click on the Find Customer button at the right of the screen, in the POS Buttons bar. (Or click on the Find Menu at the bottom right of the screen and select "Find Customer" from there. Or maybe your store administrator has created a function key or quick key to call up the Find Customer window.) The Find Customer window appears. (If you need any help finding a record--in this case a customer--please click here.)
After you select a customer, you will be brought back to the POS, and the customer you selected (name and address) will be listed at the top of the screen. Any special discounts, features, and/or restrictions in the customer's account will now automatically kick in during the sale.
