I work at Accumulus which has a recurring billing platform that de-couples payment processors from recurring billing, i.e. invoicing, price plans, customer management and notifications, etc. The thing is that you don't want to be locked into a particular payment processor long term. Convenience sells, but be mindful of lock-in. As companies grow, they get better rates with different merchant account providers. As a company, you want maximum flexibility and negotiation ability to take your business to those who give you the best value, globally.

We are putting together an offer specifically for Stripe users who want to avoid lock-in and save money long term. If you are interested, you can get on the list here https://accumulus.com/it-is-your-revenue
