StripeOnline fees: From 1.2% + 20p Pros Affordable transaction fees Supports 135+ currencies and local payment methods Excellent reporting tools Cons Takes up to seven days to pay out funds Customisation can be complicated Stripe is one of the most popular online payment processors in the UK, and for good reason. It offers transparent pay-as-you-go pricing with no monthly fees or contract for your payment gateway.Stripe supports more than 135 currencies at checkout, and you can add local payment methods like AliPay, iDeal, and more to make international payments easier for your customers.

You can also integrate Stripe with Quickbooks, NetSuite, and other popular accounting software.Stripe pricingWith Stripe, you’ll pay 1.5% + 20p per transaction for standard UK credit and debit cards, or 1.9% + 20p for premium cards (including most business credit cards).

An API offers even more flexibility and the ability to customise your checkout page.Revolut also supports online invoices and one-click payment links, making it easy for customers to pay your business online without using a traditional checkout page. There’s also a one-click payment option you can add to your website, which is great for repeat customers who want to make purchases quickly.Like Stripe, Revolut lets you accept multiple currencies and hold them in separate accounts so you can avoid foreign exchange fees. However, Revolut only supports around 25 currencies.Revolut pricingRevolut charges 1.0% + 20p for UK consumer cards, or 2.8% + 20p for UK business cards and international cards. It offers subscription plans that include business banking features, but you don’t need a subscription for online payment processing.Who is Revolut best for?Revolut is best for businesses that need multiple digital payment options, including a checkout page, a one-click checkout, invoices, and payment links.

GoCardlessOnline fees: From 1.0% + 20p Pros Supports recurring payments and direct debits 350+ integrations available Very user-friendly platform Cons Additional fee for transactions over £2,000 Limited support for customers in Asia and Africa GoCardless is one of the best solutions for recurring online payments, making it a great choice for businesses that sell subscriptions. With GoCardless, you can charge customers weekly or monthly, plus use direct debit to automatically take payments from customers’ bank accounts instead of charging a credit card.The gateway supports 30+ currencies and local payment methods. Most supported currencies are in Europe and North America, so GoCardless isn’t as suitable for businesses with customers in Asia or Africa.GoCardless has more than 350 integrations, so you can fully customise the payment gateway to meet your business’s needs. It’s fairly easy to use, which is a big plus for business owners who want to hit the ground running rather than spend hours configuring the platform.

How to Switch to a New Payment Gateway ProviderIf you already have a payment gateway, but you’re missing features or paying too much in fees, it might be time to switch. In most cases, switching is fairly easy—but there are some things to keep in mind.First, check whether you have a contract with your current payment gateway provider. If you do, there could be fees for breaking your contract. You’ll need to decide whether paying the fees is worth it for your business or whether you should wait until your contract ends to switch providers.In addition, remember that switching payment gateways can be disruptive for customers trying to make purchases on your website. So it’s important to make the transition quick and smooth.To accomplish this, make sure that your new gateway is fully customised with your business’s logo and checkout options before you launch it on your site. Make a list of all payment links on your site that will need to be updated to point to the new checkout page.Plan to switch over to the new payment gateway in the middle of the night, when it’s unlikely anyone else will be using your site.You should also run a few test payments as soon as your gateway goes live. This is a good way to ensure that your checkout process is working smoothly and that funds are showing up in your business’s merchant account.If you have any problems, don’t hesitate to contact your payment gateway provider. Most offer fast technical support to minimise the time that your business is unable to take online payments.
