Stripe

Stripe is the payments infrastructure built by the company of the same name, used by a huge share of online businesses worldwide. It's made for anyone who sells on the internet — from an individual who just wants to send a customer a payment link, to developer and finance teams who need to wire payments deep into their own product.

The idea is straightforward: you sign up, verify your business, and Stripe gives you the tools to start taking money. Card payments, bank transfers and local payment methods come in from customers; your settled revenue is paid out to your account; and a clear dashboard shows you what came in, what failed and where the fees are.
