There is a very nice implementation of this called KillBill: it's a self-hosted invoicing system that can connect to many payment providers like Stripe/Paypal/... It's really nice to be in control of the invoicing, without having to implement it ourselves, and of course not depend on only one provider. It also has support for taxes with plugins.
