Any sale can be easily associated with a customer. It's useful to associate the sale with a customer to easily locate the sale for a refund, to perform a targeted marketing campaign, or for research purposes when you'd like to know which customers have purchased specific products.Depending on your Lightspeed Retail settings, a customer may be required in order to process a sale using a specific payment type.

1. Tap the “Add Customer” icon.
2. Select a customer or add a new one:
   • Select an existing customer: Tap Select Customer, swipe down to manually search for the customer or enter the first or last name in the search field, and then tap the “add” icon to add the customer to the sale.
   • Add a new customer: Tap New Customer, enter the customer details, and then tap Save. The phone number entered here is set as the customer’s home phone number in Lightspeed Retail. The new customer is automatically added to your Lightspeed Retail system.If the customer already exists, another entry will be added for the same customer. To avoid duplicate entries, we recommend searching for the customer before creating a new customer. If you have multiple entries for the same customer, you can merge them in Lightspeed Retail.
