I'm fairly certain that Churnbuster now supports other payment processors and gateways beyond Stripe.

First let me say that there is no support like Stripe support. :-) I'm always greatly relieved when onboarding with a customer and they both use Stripe and Stripe subscriptions. But to your point, I may know something about Churn Buster supporting folks not using Stripe subscriptions or even using other payment processors. Email me at andrew@churnbuster.io for more information. :-)
