I\'m trying to research how to add a subscription based pay model on an existing site of mine, but am running into a lot of conflicting information and caused me to be a bit los
I use the SaaS Railskit, and Highly recommend it. The code is clean, commented and legible. It can be dropped in to an existing app, with minimal tweaking, or used as the foundation for a new app. I suppose it work fine if you just wanted to use it as a reference, or stand-alone payment processing app.
Hope that helps!
