Stripe is an online payment processor. Your marketplace uses Stripe Connect with Custom Accounts to power payments between the customers and providers in your marketplace. Customers can pay with their credit or debit cards. Providers can accept payouts directly to their bank accounts. As the marketplace operator, you're able to delay the payout to the provider until the customer has received the goods or services they want, and automatically charge a commission percentage from each transaction.
