Most people also don't understand that with Stripe, you don't actually have your own merchant account (this is why they can setup your account so fast).

This can become hugely problematic as your business grows since you're a sub-account of Stripe business, making you beholden to their business practices and costs.

My comments aren't intended to sound negative. There's Pro's and Con's to different business models. Getting quick access to the robust tools Stripe offers comes at the cost of you giving up some control over your companies operations.
