What is a payment provider?

A payment provider (also known as a payment service provider or PSP) is a third-party company that enables merchants to accept digital payments securely – including credit card, PayPal, direct debit, and more.

Payment providers in eCommerce

In eCommerce, payment providers ensure smooth and secure checkout experiences by processing transactions, verifying payments, and transferring funds. They integrate with shop systems and ERPs, and often support fraud prevention, refunds, and reporting. With everstox, while payments are handled upstream, all order and fulfillment flows can be connected to payment statuses via integrated order management systems.

Example of a payment provider

A fashion brand uses Stripe and Klarna to offer multiple payment options at checkout. After successful payment, the order is released and automatically transmitted to the everstox fulfillment network.
