Also, vendor lock-in with a payment processor is pretty strong. Kudos to Braintree for supporting portability, but you're still locked to an API unless you want to re-code everything.

In other words, the first $50k is free, and then you're tied intimately to BT's API. The path of least resistance is to just keep going with them. You're making money. They're making money. Everybody wins. I don't think this is a bad thing, it's just not all charity.

All that being said, if they announced this 4 months ago when I was migrating my payment system over to Stripe, I'd have been all over it. BT seems awesome and this is a great deal. Stripe won based on price[1], but $50k free really tips the scales on that.
