Space Box is a super-useful (new?) Stripe integration. User's can begin accepting payments in literally minutes, without any coding. The best part is that it handles recurring billing too. Several other services I've experimented with either do not allow sellers to accept recurring payments at all or, at the very least, require a fairly involved programatic-setup. In contrast, for a reasonable fee ($19.99/mo) Space Box makes setting up a recurring billing just as easy as a standard, one-time charge.
