Gravity Forms can handle payments through different gateways (e.g. PayPal, Stripe), so it’s definitely an option if you’re looking for a flexible solution to sell products or set up memberships/courses.

I put together a guide that goes through how payment gateways work, the ones officially supported by Gravity Forms, and a comparison that can hopefully make comparing your options easier.
