Now that your business is ready to take payments, it’s time to think about how you’ll be processing payments. Alternatively, you might just want to change your current payment system. It’s time to think about what are the best payment processors for you and your business.

You’ll find that payment processors perform largely the same tasks, but it could be a single feature – or the cost – that’ll steer your final decision.

Knowing what’s on the market will help get you going, which is why we’ve compiled a list of the most widely recognised systems. But first: a quick definition.

What is a payment processor?

A payment processor is a third-party payments system, sending between your customer’s bank account and your business bank account. Payment processors can also authorise transactions and work on merchants being paid within a certain time period.

The term is often used interchangeably with payment gateway, a means of approving a payment. Many firms combine payment processors and payment gateways in one product, so you’ll more commonly see it referred to as a payment gateway.

What payment processor should I go for?

Let’s compare some of the best payment processors on the market, focusing on cost, pros, cons and what kind of payments the system is best suited to.


What is it? WorldPay has specialist small business packages which you can fit to your requirements. You can choose your equipment and pricing plan. You’ve got countertop card machines, portable card machines, mobile card machines and mobile card readers.

Payment gateway (Paypal, debit and credit card payment), email link, virtual terminal (over the phone using a secure web browser).

How much does it cost? WorldPay has three packages: Simplicity, Fixed Monthly or Custom.


Gateway fee: 10p for every transaction
Monthly online payments gateway fee: £19.95
Risk manager: 10p per transaction

Transaction fee (debit and credit card): 2.75pc + 20p

Fixed Monthly

Monthly package fee: from £49.99 (includes transactions up to set threshold and authorisation fees) Risk manager: 10p per transaction.

Credit cards: 2.75pc
Debit cards: 0.75pc


Custom is a bespoke package which you can get a quote for based on your needs

Pros: WorldPay works with card providers around the world (130 different countries in 116 currencies) with 24-hour UK customer support

Cons: Factoring in the monthly and per-transaction fees, it’s a payment processing system that can get quite expensive. Some reviewers say there can be a delay in getting money to small business owners as well as a lack of product transparency and forceful sales tactics. The auto-renewal opt out process is difficult. You need to write to WorldPay within 30 days of your contract expiring to tell them you don’t want it renewed, otherwise you’ll be signed up to an extension and forced to pay early termination if you want it to end.

Best for: Newer or smaller businesses with lower transaction volumes or medium-sized businesses with consistent transaction levels all year round.


What is it? With Square, you set up an account and buy a reader online or in-store. You’ve got the option to take payments in person, over the phone, by invoice or online. The basic version comes with free real-time analytics as well as inventory and location management.

How much does it cost?

Chip and PIN payments: 1.75pc
Card-not-present transactions including keyed-in transactions, card payments over the phone with Virtual Terminal, Square Invoices and eCommerce: 2.5pc

Pros: Square is an easy to use payment gateway with quick launch and a free magstripe reader which accepts international cards. Invoicing and virtual terminal are also included. Integrate Xero and Excel for accounting and elect to get your money the next business day.

Cons: Square doesn’t take smartphone payment and the cost per transaction from major card providers is pricey. That’s before you consider the no limit on per-transaction fees could see fees rocket if you have a busy period or you experience fast business growth.

Best for: Small businesses with less consistent sales who want to start up quickly.


What is it? Stripe is a payment solution for online payments which is customisable with applications and third-party integrations.

How much does it cost? Depending on the size and sales volume of your business, you’ve got two options.


European cards: 1.4pc + 20p
Non-European cards: 2.9pc + 20p

Currency conversion: 1pc


Design a custom package for your business if you have large payments volume or unique business needs, Base it on volume discounts, interchange pricing, multi-product discounts and country-specific rates   

Pros: It offers simplicity, with customised billing plans for membership and subscriptions, two-day rolling bank transfers which can be made weekly or monthly depending on when you want to get paid. Stripe also offers integration with the mobile app, uses 135 different currencies and customers don’t need an account in order to pay so the process is seamless. There are no setup fees, monthly fees or hidden fees to worry about either.

Cons: The chargeback policy may lead to some aggravation. You’ll be charged £15 for any disputed transactions and only refunded if a dispute is resolved in your favour. As you might expect, it’s complicated for non-technologically minded people. Stripe holds onto merchant money for longer to protect them from fraud but it’s still longer than its competitors.

Best for: Online businesses with access to a developer.

Manage your inventory, send abandoned cart emails and get a better grasp of your performance with real-time sales analytics.

PayPal Here

What is it? From PayPal, Here allows payments to go offline with card and contactless payments, including Apple Pay and Android Pay. Manage your inventory and generate reports. Everything is managed within an app with a variety of online support articles.

How much does it cost?

Card reader: (£45 + £9 VAT)
Transaction fee: 1pc – 2.75pc per transaction.

Pros: It’s easy to set up, accounts are authorised almost instantly, it’s simple and secure, quick for customers and support is provided by phone or email.

Cons: PayPal’s big name makes it a target for fraudsters, despite its high level of anti-fraud measures. This also means that your account could be locked at short notice for security reasons.  What’s more, disputes tend to be resolved in favour of buyers, but potential customers could be disadvantaged by not having a PayPal account.

Best for: A business that doesn’t want a bulky physical payment unit and whose customers use PayPal.

Amazon Pay

What is it? I’m sure this payment system needs little explanation. Customers on Amazon Pay can make purchases using their Amazon account and do their shopping by voice with Amazon Pay for Alexa Skills.

How much does it cost? Your payment processing fee will depend on your monthly payment volume while the authorisation fee remains consistently at 20p per transaction.

Less than £1,500: 3.4pc

£1,500.01-£6,000: 2.9pc

£6,000.01- £15,000: 2.4pc

£15,000.01 – £55,000: 1.9pc

Above £55,000: 1.4pc

Cross border fees (for sales outside the UK): up to 1.5pc

Chargeback dispute fee: £14.

Pros: Amazon Pay gets a huge boost from its name recognition – lots of people have an Amazon account. Shopping is quick and easy if the user is already logged in, but you can embed a “buy now” button on your site to make purchasing even easier. It’s also high security, offers merchant protection and integrates with Shopify and BigCommerce

Cons: Like PayPal Here, Amazon Pay can be quite a target for fraudsters. You may find your account being shut down without prior warning for security reasons, there’s no PayPal support and the transaction fee is pretty high.

Best for: Online retail businesses.

Shopify Payments

What is it? Shopify Payments allows you to accept credit cards directly with Shopify in contactless, Chip and PIN or by swiping the customer’s card.

Offers online payments solutions and eCommerce as well as a point of sale system.

How much does it cost?

Cons: There’s no phone support on Sundays or late evenings, nor is there an in-built receipt printer.

Best for: Remote businesses, such as freelance beauticians or food vans.

Pros: Adyen has no monthly fee, no set-up or application fees and no early termination fees.

Cons: With those fees, it’s expensive for businesses with lower volumes of sales. Plus, it’s no good for high-risk merchants (ones that get a significant number of chargebacks) as you’re more likely to get blocked. The system is not really designed for brand-new start-ups – you must already be taking payments if you want to use Adyen.

Best for: Better for larger SMEs, not start-ups.
