Accepting other forms of payment
You can accept any form of payment outside of the system, by using an "offline payment" payment processor as an alternative for checkout. See this example:
Example payment page with 2 alternatives. The descriptive text and the buttons are customizable.
Your offline payment instructions. The photographer is notified when the client clicks on "Accept".
Once an offline payment is received, a single click on Mark order as paid in your admin space will initiate the automated delivery of any licensed image file present in the order.
