To add Existing customer information to a sale, locate the cursor in the Customer ID box on the Sales screen and type in the customer's ID. If you do not know the customer's ID, you can press the Find Cust button (or right mouse button click on the customer panel and choose Find) and search on the customer's last name, first name, city, phone number, or Customer ID. If you are adding a New customer to the database, press Alt-W, F3, or press the New Cust button. This will display the Edit Customer screen and allow you to add a customer. Once you have filled in the new customer information, press the Save button to save your customer and add the customer to the Sales Screen.
