Stripe and BrainTree (to name two) seem amazing, but as always, they're only for US companies. How about we list all the (good) e-payment companies available to non-US companies? I'm personally interested in companies that let you charge customers several times (different amounts) once they put their credit card number (not just recurring payments, but at any time), but it would still be interesting to find out any good payment company, you never know.
