Which payment gateways work with subscriptions?
All you need to process subscriptions is a payment gateway that will process credit card payments. Any of the other 50+ payment gateways will work with Cart66 subscriptions and recurring billing. Everything required is built into Cart66. Cart66 subscriptions do not require any add-on services at the payment gateway level. All the payment gateway has to do is process credit card transactions. Storing the customer's billing information and the recurring billing recipes of when to charge and how much to charge is all handled by Cart66.
Subscriptions in Cart66 Cloud require an on-site credit card processing payment gateway which includes PayPal Pro but it does not include PayPal Express checkout, PayPal Website Payments Standard, Dwolla, or GoCardless. If you are using PayPal Pro, it does not require the end user to have a PayPal account.
