It’s easy to get confused by terminology in the world of payments, especially when so many overlap and sound similar.

Two of these are ‘payment processor’ and ‘payment gateway’, whose meanings are often unclear. What they have in common is the role they play behind the scenes, somewhere between a customer making a payment and the money arriving into a business’ bank account. 

We’re here to walk you through a payment gateway vs payment processor, and the importance of having a solution in place that covers them both.

What is a payment gateway?

A payment gateway, as the name suggests, is the service that opens up the flow by helping businesses initiate payments. 

They can be provided by a business’ bank, or standalone as a separate service connecting to one or multiple payment processors. Some focus on only one type of payments, for example ecommerce or in-person payments. But the best way to keep agile and minimise integrations is to pick a gateway that has the capabilities to process multiple payment types.

What is a payment processor?

A payment processor comes next; a company that acts as a mediator by processing transactions on behalf of a business’ bank. 

Operating in the background, a processor ensures the payments are compliant with the standards and rules of the country in which the business is operating. The payment gateway sends information of the transaction to the payment processor, which connects directly to the payment network to authorise and clear/capture the payment. 

But here’s the part that makes both clearer.

Payment gateway vs payment processor: What’s the difference?

While a payment gateway is the initiator for business’ payments, a payments process takes control of the technical side of processing payments on behalf of an acquiring bank

Usually, a payment gateway and payment processor are two separate systems. But having a single solution that has both can bring a host of benefits for your business, including increased efficiency and reliability.

How a payment gateway and payment processor work together

A surprising amount of steps take place in just the few seconds in which payment processing is occurring.

We’re going to walk you through them: 

  1. Once a payment is initiated, the business forwards the customer’s payment information (e.g. cardholder details) to the payment gateway. 

  2. The payment gateway adapts the information to meet the proprietary standards sharing it with the local payment processor. 

  3. Next, the payment processor passes this information onto the card payment network, which shares it with the customer's bank to carry out checks, for example if there are sufficient funds in the account.

  4. Depending on the results of these checks, the customer’s bank lets the card network know whether the transaction is approved or declined. 

  5. This message is passed onto the payment processor by the card network, and it is then sent on to the payment gateway, which relays this information back to the business and customer to finalise the purchase. 

  6. The funds are transferred from the customer’s bank account to the acquiring bank, then to the business’s bank account and is typically initiated before close of day.
