http://www.spreedly.com http://www.spreedly.com provides credit card vaulting as a service. You can build your own billing system on top of it with minimal PCIDSS compliance burden. They support 53 different gateways for using that information once you've stored it, all with a single unified API. You're also not locking yourself into a payment processor, which you are if you choose to build on top of Stripe or anyone else. By not using any processor's storage solution, you're free to bill your customers with one processor one day, and another the next. You might like Stripe now, and they might lock your account for suspected fraud tomorrow, or some new shiny payment startup called Polkadot might be who you want to use in 3 years.
