What is a payment gateway?

A payment gateway is the piece of digital infrastructure that allows you to accept card payments. It’s the software that processes the customer’s card data, and enables a quick, secure transaction to take place.

Payment gateways aren’t just for selling online, either. Whether you’re taking a card payment online, or face-to-face through a countertop card machine or mobile device, it’ll be passing through a payment gateway.

A useful way to think of it is that it’s like… a gateway! It’s a place one thing (the customer’s card details) needs to go through to get somewhere else (authorisation of the card by the bank involved). Simple, right?

Well… there is one more thing. You’ll need also need a merchant account before you can start taking payments for your business. A payment gateway makes the transaction happen, but you still need somewhere for the money to go.

Payment gateways commonly come in a package when you set up a merchant account, like with Worldpay. But, payment gateways like Authorize.Net offer a service that can work alongside a merchant account from a different provider.

Top 6 things to consider before choosing a provider

1. International support

In today’s world, you can’t afford to lose business from abroad – or because a buyer didn’t have the right card. Make sure your payment gateway supports different card types and currencies, so your business can blossom beyond borders.

2. Transaction volume

Payment gateway fees can be fickle things; transaction rates often go up and down depending on how much you’re turning over. Have a think about how much you’re expecting to sell, and how many transactions will be going through your gateway. It’s absolutely crucial in selecting the cheapest supplier for your business.

Not sure what we mean? Check out the examples of Oliver and Daniela below, or click to compare quotes.

3. Customer support

Time is money. So if there’s an issue with your payment gateway, you want it sorted as quickly as possible – or you face missing out on sales. What kind of customer support does your provider offer? Is it just web-based service like a chat bot, or can you call up and speak to a real person? Is it available 24/7?

4. Hosted or API?

At some stage, you’ll also need to have a think about how you want to add the payment gateway to your website. The easiest option is to host it on the payment provider’s site. This is also ideal because it means you don’t have to worry about tricky PCI compliance. However, your customers get redirected away from your site to pay.

The other option is to use an API integration to slot your payment gateway straight into your website. It makes for a smoother payment journey for the customer, although you’ll need to take care of your own…

5. PCI DSS compliance

This is the Payment Card Industry’s (PCI) Data Security Standard (DSS). It’s designed to help protect cardholder data and reduce fraud.

No matter how big your business is, you’ll need to stay compliant – if you’re taking card payments, that is.

Make sure your payment gateway provider is PCI DSS compliant before you go anywhere near signing a contract!

6. Cart compatibility

A payment gateway processes the transaction, but your website will still need a shopping cart system in place. That’s where your customers browse your products, add stuff to their carts, and eventually (hopefully!) hit ‘checkout’.

Your payment gateway and your shopping cart system need to talk to each other loudly and clearly if you want your buyer’s journey to be a smooth one. Which is why you’ll need to make sure your payment gateway providers offers integration with whatever current shopping cart you’re using.

Luckily, most payment gateway providers offer a full breakdown of the programmes and integrations they offer. Just make sure you check ‘em!

How much do payment gateways charge?

Great question. If you’ve read the above, you’ll have an idea of some of the costs that come with a payment gateway for your business – and how dependent the fees are on which provider you pick. Payment gateway fees come in a few different shapes and sizes, but most break down as follows:

how much do payment gateways charge

Transaction fees

These are what you pay for every time you accept a card payment. They’re commonly a percentage of the value of the transaction (usually between 1-3%, but it can be even more, or less).

Transaction fees can also be a fixed rate per sale (in the region of pennies, rather than pounds – don’t stress!), or a combination of both a percentage and a flat rate. See Oliver’s situation below for an example of this.

Set up fees

This is the charge to get your payment gateway up and running. We found that most providers actually don’t ask for one, which is good news. And it makes sense – it’s a competitive market, and each provider wants to rope you into its own payment ecosystem.

Monthly fees

Some providers will also charge you a set monthly fee for their services. Generally, payment gateways that come with monthly charges offset these with lower transaction fees. Or, they’ll offer a set amount of transactions (often your first 350-400 per month) free, as a deal-sweetener. See Daniela’s case study below for an example of payment gateway monthly fees in action.

Oliver payment gateway comparison case study


Oliver uses a payment gateway from Stripe to sell clothing within Europe. He sells a shirt on his website worth £30 to a customer paying with an EU card. Stripe takes a transaction fee of 1.4% + 20p for its services, so Oliver receives a total of £29.38 in his merchant account. Stripe is ideal for Oliver because he does fewer, lower value transactions a month, and Stripe’s ‘pay as you go’ payment gateway doesn’t charge any monthly fees.

Daniela payment gateway comparison case study


Daniela uses Sage Pay for her thriving online bookselling business. She’s on the most basic plan, which sets her back £20.90 in monthly fees. One of her customers buys a cookbook worth £60. They pay with a credit card, so (minus Daniela’s transaction fee of 2.09%) she receives £58.75. Daniela chooses Sage Pay because, with her plan, she gets her first 350 transactions free . So it’s well-suited to her busier, higher-volume bookselling business.

Are there free payment gateways?

Well, we hate to break it to you, but…. No. As the old saying goes, “there’s no such thing as a free payment gateway.”

How come? Put simply, all card transactions attract a charge. It costs the provider to facilitate your online payments, so they need to charge you something to cover their own costs. And, of course, like all businesses, they need to make money.

The point is that, while many payment gateways don’t incur an initial cost, you’ll always have to pay some kind of usage or transaction fee. Turn away from any company claiming to offer you a free payment gateway, and run in the opposite direction!

Looking at the table, it’s easy to feel confused by the often mercurial payment gateway pricing. Even with the same provider, there can be so much range around the transaction percentage you can expect to pay. Why is this, you ask? A couple of reasons.

  • Transaction fees vary by the online payment method your buyer chooses. It’s annoying, but it’s true. Credit cards generally incur a higher fee than debit cards. And providers like Stripe charge higher fees for non-EU cards.
  • Fees also vary depending on the amount of transactions you make. The big guns like PayPal do this, because they make money when you do. The more online payments you process with them, the less fees you pay.

Most online payment gateway providers don’t like rolling over and showing the soft underbelly of their pricing plans; and you often have to trawl through pages of marketing speak to get anywhere on the websites of some companies.
