A payment processing systems (like Stripe) allow business to accept payment from customers, without having to build their own payment processing infrastructure.

  * Consider card authorize, capture and combined flow (authorize + capture).
* Merchants should be able to schedule recurring payments (for example monthly subscriptions).
* Merchants should be able to cancel or refund payments.
* Users should be able to pay for products with credit/debit cards and bank accounts.
* Merchants should be able to view status of payments (e.g., pending, success, failed, chargeback).
