The best payment gateways provide a simple way to take and process credit and debit card payments online.
Payment gateways offer the flexibility of being able to take card payments, either online or in-store. The allows quick and easy credit card payment processing, both online and offline. Payment gateway systems also work with Point of Sale (POS) processing in-store.
Put simply, payment gateways provide a means to charge cards and any fees are subsequently charged to the business owner, or merchant, with rates commonly anywhere between 1.4%-3.5%, and often with no monthly fees either.
In addition, if you have a merchant account, processing fees are reduced to around interchange fees, which are typically around 0.10%-20% per transaction, and come with monthly fees.
Having a simple payment gateway can be a great way to handle low volume sales. However, as monthly fees can eat into income more than processing fees you may find that once sales volume reaches a critical threshold it becomes cheaper to pay a monthly fee for merchant processing with interchange fees.
Some of the best payment gateways offer both options, or a similar advantage over the competition. This may be in the form of processing fees for certain cards, to direct integration into accounting software. The same can be said for anyone with dedicated accounting software needs in the UK too.

It also offers easy cart integration, plentiful customization options, online invoicing, and facilitates credit card payments over the phone.
PayPal is normally associated with online marketplace eBay, but it’s worth noting that since 2020, it ceased to be eBay’s main payment option (as the company switched to Adyen – although PayPal is still offered as an optional payment service). In a statement made last year, eBay said it made the move to offer customers more competitive prices.
Pricing is competitive, with card processing charged at 2.9% per transaction, with no monthly fees, making it ideal for new and small businesses.

Other payment gateways to consider
While we've mentioned some of the best merchant gateways, there are a number of others worth considering. This is especially as many are available to integrate with existing ecommerce platforms using nothing more than an easy-to-install plugin. Here, therefore, we'll list some additional merchant gateways that are well worth considering, according to the differing needs of online businesses.
2Checkout is another payment provider that is commonly used by online merchants, not least because as well as one-off purchases it's easy to set up subscriptions. This makes it especially useful for online businesses selling digital services such as web hosting or web design companies. It's also commonly available as a plugin for major ecommerce platforms, and can process a wide range of global currencies.
Opayo, offers not just a merchant gateway, but the ability to directly record all sales and transactions directly into your Sage accounting software. This makes it especially invaluable for efficiency purposes, not least because it means you can see your costs and income in real-time. However, while there are different plans available for Opayo, it's best to have a merchant account to get the most out of the software, not least for reducing transaction fees in the first place.
FIS Global (previously Worldpay) is another popular payment gateway, with a number of integrations available for popular ecommerce platforms. You can set up as a paid-monthly service, or else use a merchant account to take advantage of interchange fees on all transactions. However, Worldpay has undergone significant changes over the past few years, after being owned by at least two different companies, so it's worth inquiring as to what services are currently available and at what price.

What is a payment gateway?
Payment gateways are tools used by merchants to receive payments from customers.
An online payment gateway is cloud-based and it helps merchants receive online payments from customers, while a brick-and-mortar retail store's payment gateway is a point-of-sale (POS) system or a card reader.
How to choose the best payment gateways for you?
Choosing the best payment gateway to suit your business needs largely depends on what size your company is. If you're a smaller outlet, or sole trader, it may not be necessary to have a powerful payment gateway setup. That's especially so when you consider the sort of flexibility and convenience offered by PayPal.
Being able to offer the convenience of accepting card payments is an everyday necessity for most businesses and customers expect to have the option. So lookout for those that offer simplicity, value for money and also the opportunity to link them to POS systems, along with the ability to integrate into your accounting software.
At the same time, keep an eye on those terms and conditions, as outlined in our introduction. Fees can vary wildly from one payment gateway to another, so be sure to factor this in to your costings. Processing and interchange fees can add up, so be sure to allow for these.
If your business plans to process higher volumes of sales then you'll obviously want to plump for one of the more advanced packages, even though these invariably come with a higher price tag.
