How do I use the No Payment Necessary method?
If a customer has a $0.00 balance during checkout, (for example, they use a gift card that pays for the whole order), you can add a "No Payment Necessary" method to allow the processing of the order.
This method of payment is already setup for you in your account. We suggest you do not delete it as you may have customers that use gift cards. If necessary, the following steps can be used to re-create the "No Payment Necessary" method.
