2. PayPal: Best for fast transfers


You may remember PayPal from such hit e-commerce websites as eBay, where it made checking out more pain-free than we ever thought possible. But PayPal is just as user-friendly for businesses as it is for customers.

PayPal’s payment gateway is especially perfect for international businesses (or any with their eyes set globally), as it accepts a whopping 26 currencies in over 200 markets.

3. Stripe: Best full service payment provider
