How can I add a customer?

When creating an invoice or payment link, you have the option of adding a new customer or selecting from the list of previously added customers. To add a new customer, click on 'Add new customer' in the Customer drop-down and simply fill in the required customer information such as customer name and email. You can also choose to add an address for the customer if you like. Click on 'Next' and the customer details will be stored for future use.
