In Person Online Over the Phone Multiple / Other Submit How much should I pay for a payment gateway?Payment gateway fees vary for each business. Essentially, the more money you process in card transactions, the less you’ll pay to your provider.The only way to get an accurate idea of costs for your business is to request a tailored quote, but let’s look at some ballpark figures.Payment gateway: guide pricesJoining feeFixed monthly feeTransaction feesUp to £50£10 to £2010p fixed or 2% + 20pMonthly fees and lower transaction fees vs no monthly fees and higher transaction feesContract providers offer their service for fixed monthly fee, which covers transaction fees up to a certain threshold, and then charge low transaction fees per payment you take once you go above. The payment gateway from Handepay, for example, is charged at £19.99 per month for the first 400 transactions, after which you pay an additional 10p for every payment processed.Mobile card readers, however, don't charge you an ongoing monthly cost but bite a bigger chunk off your transactions. Examples of these include:Stripe Payments (1.5% + 20p)SumUp (1.69%)Zettle (1.75%)Square (1.75%)If you're a small business ownerIf you’re a small business owner determined to find yourself a free payment gateway, then it’s worth looking at alternative online payment methods such as Paypal — it’s the closest you’re going to get!PayPal is a third-party payment service provider. There's no fee for setting up your payment gateway account, no monthly charge, and transaction fees come in at 2.9% + 30p.Mobile providers like the ones listed above are also good options for you, especially if you run a brick-and-mortar business – in which case, you can benefit from the card readers they provide.If you're a mid to large-sized businesses business ownerMid to large-sized businesses might be better served by a traditional payment gateway provider, such as takepayments or Clover, or by a bank, such as Barclaycard. This is because traditional providers tend to have much lower transaction fees and often operate on a sliding scale, depending on the number of transaction your business processes. Cheapest payment gateway providersThese guys might not offer a free payment gateway, but they come close. And, importantly, you can rely on them to provide secure payment services for your business. Worldpay Worldpay has recently launched a new payment gateway called Worldpay eCommerce. With no monthly charge, no minimum fee and no set-up fee, it's the cheapest out of the traditional providers we compared.For Visa and Mastercard consumer cards, the transaction fees are set at 1.3%+20p, whereas commercial cards and Amex are charged at a separate rate. However, you'll need to be locked into an 18-month contract to access these fees.Worldpay's card machine costs £17.50 per month, while its virtual terminal costs and £9.99 per month.Worldpay offers over 100 integrations and accepts over 120 currencies. You can also access analytics and reporting, but this is hidden behind a paywall of £4.99 per month. If this is important to you and you don't want to pay extra, Stripe provides comprehensive reporting without the price tag. Although Stripe includes several reporting options, its transaction fees (1.4% +20p) may not be suitable if your business takes lots of small payments. Plus, you're more likely to get a much better rate for transaction fees with Worldpay.Given that it offers a generous range of integrations and analytics features, Worldpay is a suitable option if you want to switch to a solution with more advanced features than your current payment gateway offers.It is also a suitable option for small businesses seeking a payment gateway, thanks to its low fees and quick next-business-day settlement.Following our extensive research and testing, we gave Worldpay an excellent score of 4.7/5. While it offers cheap transaction fees, it also transfers funds within 30 minutes, which is super handy for businesses that need the cash flow. Expert Rating: ★ ★ ★ ★ ★ Revolut Revolut earned a score of 4.8/5 from us following our research and testing – one of its best qualities is that it's one of the most affordable mobile reader providers we analysed. For UK consumer cards, transaction fees cost 1% +20p for in-person transactions and 0.8% + 2p for in-person transactions. For all International and commercial cards, the rates are 2.8% + 20p for online transactions and 2.6% + 2p for in-person transactions.Revolut's card reader costs a one-off of £49 and, while there are cheaper readers, such as Square's £16 reader, Square's transaction fees are much higher at 1.75%. So, in the long term, Revolut is much cheaper because you'll receive more money from each transaction.Revolut doesn't just boast cheap transaction fees but it's a pretty well-rounded provider as it includes: over 16 integrations, reporting, and accepts over 30 currencies. Expert Rating: ★ ★ ★ ★ ★ Stripe Stripe is a mobile card reader, scoring a strong 4/5 in our research. Stripe charges 1.5% + 20p per transaction for standard UK cards and 2.5% + 20p per transaction for EU cards. Its card readers cost £49 or £179, which is a little pricey. However, these are typically one-off costs, unlike traditional readers where you have to pay monthly. A one-off fee is well-suited to small businesses or startups that aren't quite ready to commit to a long-term contract and instead need the flexibility of a mobile reader, like Stripe.Our research has found that Stripe is the best mobile reader for reporting, offering several reporting options that include: real-time reporting on charges, funds, and transfers. It also accepts over 135 currencies.Although Stripe has great features, its transfer fund time is around three to seven days, much longer than Worldpay's time of 30 minutes and even Revolut's time of one to three days. If you're a business that finds cash flow to be important, you might be better suited to Revolut if you want the flexibility, or Worldpay if you don't mind the contract.
