1. takepayments: best if you need flexible payment solutions

How much does it cost?

takepayments standouts amongst its competitors because, unlike the other providers we’ve included on this list, it doesn’t charge standard processing fees. Instead, it provides bespoke transaction fees to clients depending on turnover and business needs.

This is a huge benefit, especially if you’re concerned with scalability. Rather than being locked into one fee, your business will be able to grow and adapt with takepayments’ customised pricing structure.

Unlike its competitors Clover and Square, takepayments does charge a fee of £25 per month for using its platform. This is higher than Barclaycard’s £15 per month fee, but less than Worldpay’s £40. The fairly expensive monthly rate could well be worth shelling out for if you’re able to agree on a low rate for your transaction fees.

takepayments also offers its card machines on a monthly lease basis, which is good news if you’re trying to avoid upfront costs, but bad news if you want to own your card machines and avoid ongoing fees. If you’d prefer to buy outright, you could take a look at Clover instead.

• Contract: Yes
• Contract length: One month minimum
• Processing fee: Quote based
• Setup fee: None
• POS hardware costs: Quote based monthly prices, terminal rental rates start from £7.50 per month
• Free trial or plan: None

Why is takepayments a top choice for my business?

From pricing, to its card machines, and help and support options, we were impressed to find takepayments performed strongly on almost every level.

takepayments provides everything you need for an all-in-one POS ecosystem, without the need for additional third party software or hardware. Its handheld card machines come fully integrated with robust POS software, meaning you can take payments, manage your sales, and get extensive reporting data all from a single card reader. This keeps your costs low and your operation lean.

Another positive; superfast next-working-day payouts! Most merchant services offer payout times of up to three working days. Worth considering if you rely on receiving your profits as soon as possible.

That said, out of the 18 UK-based merchant account platforms our research team analysed, takepayments was only one of four that didn’t offer a mobile app – a rare stumble for this provider.

Aside from this pain point, takepayments’ bespoke transaction fee pricing structure – in conjunction with its top-class hardware design, fully fledged POS system, and robust help and support options – crowns it the top choice for almost any small business looking for a merchant service.

What our researchers think

The standout feature of takepayments for me is that everything is bespoke and fitted to you and your companies needs. They don’t offer a one size fits all package and this is going to give your business the best chance of growing organically and know that you’re never paying more than you should for transaction fees.

2. Clover: best for an all-in-one solution

How much does it cost?

While Clover’s cheapest transaction fee of 0.2% might seem pretty miniscule – it’s by far the lowest on this list, even cheaper than Worldpay’s 0.75% – you need to read the fineprint! Clover’s fees are dependent on your business size and specific needs and aren’t guaranteed. Always read terms of your merchant agreement thoroughly and with care before signing, and keep an eye out for any hidden costs.

Something else to be aware of is that any sale made by Mastercard Business Debit card will be subject to a significantly higher 2.25% transaction fee. If a large number of your clientele are users, this will impact your profits.

There’s a caveat though: the hardware is expensive. Clover’s card machine, the Clover Flex, costs an eye-watering £450 upfront. This is on the upper end of card reader pricing, so to avoid steep upfront costs you may need to take your business elsewhere.

• Contract: None
• Highest processing fee: 2.25% for Mastercard Business Debit cards
• Lowest processing fee: 0.2% for most card payment methods (including Mastercard and Visa)
• Setup fee: None
• Monthly fee: None
• POS hardware costs: £450 for the Clover Flex
• Free trial or plan: Free plan

Why is Clover a top choice for my business?

Our analysis rated Clover a top contender due to its advanced sales analytics dashboard. Fully equipped with features like a robust inventory management system and the option to add notes to customer orders (such as a specific request), means that you can manage your entire business from one card machine. What fledgling micro-businesses – coffee stand or flower stall for example – wouldn’t value this?

If you need fast payouts, Clover’s ‘rapid deposits’ feature transfers your funds to your bank account in one business day. Keep in mind, though, that the charge for using this feature is 1.5% of the deposit amount. Otherwise, payouts can take between one and three business days.

We were also impressed by Clover’s exceptional offline functionality, which allows you to take payments without an internet connection. Other merchant services on this list also offer this, but Clover alone can take offline payments for up to seven days – a standout feature if you’re a mobile business operating in areas with poor or no signal.

During our testing, we found Clover to provide a solid help and support infrastructure, and we were pleased to find that the answers to our questions were reassuringly accurate. Clover provides a perfectly adequate range of support channels, including a knowledge centre, but we found ourselves missing the addition of an online forum. It’s also worth noting that Clover doesn’t offer 24/7 support – it operates 8am til 9pm on weekdays. If you want the safety net of round the clock support, you’ll need to jump over to Barclaycard or Worldpay instead.

What our researchers think

I loved the clover platform thanks to its huge app store that allowed me to connect with tonnes of apps, and the ease at which you can link multiple selling platforms. They have a great in-person choice as well as excellent ecommerce options that can link to sites like Shopify and WooCommerce.

3. Barclaycard: best if you want to avoid hefty upfront costs

Barclaycard’s small business card reader can be used across multiple devices, including mobiles and iPads, for wait staff and managers to use.

How much does it cost?

With a very competitive 1.6% transaction fee, no initial setup fee, no need for a monthly contract, and no upfront costs for its card machines (these are leased for a monthly fee), Barclaycard makes for an incredibly attractive proposition from a cost saving perspective.

In addition to its 1.6% rate, Barclaycard is also able to provide bespoke quotes based on your business needs, which could help you grow and scale your operation organically as your turnover expands.

There’s only a couple of catches here that you need to be mindful of. The first is that Barclaycard charges a £15 monthly fee to use its merchant service (though this is less than takepayments’ £25 monthly charge and far less than Worldpay’s £40). The other caveat is that you will need to have a Barclays bank account. Worth noting; Barclaycard offers up to a very generous £3,000 to help cover any exit fees.

• Contract: None
• Processing fee: From 1.6% (bespoke fees can be arranged, dependent on your turnover)
• Setup fee: None
• Monthly fee: £15 + VAT
• POS hardware costs: Monthly fee from £15 + VAT (or a one-off fee of £29 + VAT for the Barclaycard Smartpay Anywhere)
• Free trial or plan: None

Why is Barclaycard a top provider for my business?

Barclaycard combines its extremely competitive pricing structure with a robust range of card machines, including a portable card reader with a built-in receipt printer that can last a full day on a single charge.

Barclaycard’s Smartpay Touch card machine can act as an all-in-one POS solution, giving you the power to add products, print out sales reports and customer receipts, and access sales data all from the card machine, meaning you can be fully equipped to make and analyse sales. We need to flag that Barclaycard’s card machines can’t take payments offline, so if your signal drops you’re out of luck. For a service with some excellent offline features, you’ll want to check out Clover instead.

Barclaycard also provides a reassuring 24/7 fraud monitoring services if you’re the type of merchant who’s dealing with stressful high value transactions – such as trading in luxury items like watches, jewellery or vehicles. Our testing gave us a high level of confidence in Barclaycard’s support services, not just because of its all-hours accessibility, but because of its knowledge centre and the level of accuracy we received in response to our queries. The only significant miss is no live chat function for getting speedy answers to any queries, and they’re also missing any form of forum support.

While Barclaycard’s transaction fees are some of the lowest we’ve seen (aside from Worldpay), it doesn’t offer next-day payouts – usually taking one to two business days – so go to takepayments if you have a need for speed. Despite this, all-in-all you’ll still get a lot of bang for your buck from Barclaycard.

What our researchers think

If you already bank with Barclays, then I’d highly recommend choosing Barclaycard for your online payment solution. I’m really impressed by their 24/7 support and fraud monitoring and the fact that they offer up to £3000 for switching platforms.

4. Square: best for a simple and straightforward solution

Scooby’s Coffee in Wenlock, East London, uses the Square reader as it takes up very little space on the shop’s small counter.

How much does it cost?

Square offers a free plan, meaning it doesn’t charge any setup costs and, unlike with Barclaycard, takepayments and Worldpay, there are no monthly costs to pay either.

However, Square’s transaction fees are about average. They’re not remotely as competitive as Worldpay, but we’ve definitely seen worse. So, don’t dismiss the Square option if its other benefits work for your business.

• Contract: None
• Highest processing fee: 2.5% for payments manually keyed-in to the Square Point of Sale app
• Lowest processing fee: 1.75% for each contactless, chip and PIN or swiped card-present transaction
• Setup fee: None
• Monthly fee: None
• POS hardware costs: Ranging from £19 + VAT to £149 + VAT upfront
• Free trial or plan: Free plan

Why is Square a top provider for my business?

One of the major strengths of Square as a platform is that it provides an entire payments ecosystem, with in-person POS and ecommerce all under one roof. Essentially, it’s a one stop shop, so you won’t have the headache or cost of third party software, hardware or integration.

Square can also provide merchants with fast one-business-day payouts, a feature that could be crucial for your business model. Not only that, you’ve the ability to decide when you receive your payouts with a customisable schedule.

Of all the merchant service software we tested, Square impressed our experts the most. Unlike our other listees, Square offers a Tap to Pay function for both iPhone and Android which allows you to accept contactless payments using your smartphone instead of a card reader (Worldpay offers this feature, but only for the iPhone). Square also boasts advanced security features and an offline mode.

Square also offers a wide range of POS hardware to utilise the excellent software. You’ll have a choice of the Square Register, Square Terminal, Square Stand and Square Reader. Be aware Square doesn’t currently offer a card machine that can connect via mobile data. So, mobile businesses with intermittent wifi should look to the Clover Flex instead.

An overall strong contender, Square could have placed higher if analytics and sales reports could be filtered by card types and existing POS hardware or software could be integrated into the Square ecosystem.

Our tests on the Square support system provided helpful and fully accurate answers but only from 9am to 5pm on weekdays, which is pretty weak compared to some of its competitors, especially a 24/7 service like Barclaycard’s.

5. Worldpay: best for high volume businesses

At a Nisa Local in South London, manager Kameron Patel described his experience with the Worldpay card reader, stating that “it has never caused me any hassle, and does what it is meant to do efficiently, with no problems”.

How much does it cost?

Depending on your processing volume, Worldpay charges a rock bottom fee of 0.75% for debit cards, which is a pretty incredible rate considering the UK average across providers is 1.75%. The catch? Worldpay charges a hefty £40 per month for the service. That’s considerably more than takepayments’ £25 monthly charge, and more than double Barclaycard’s £15 per month.

Unlike with the other providers on this list, you’ll have to enter into an 18-month minimum contract with Worldpay, and pay an exit fee if you choose to switch. A high volume of sales might make this worth the cheap transaction fees, but just keep it in mind before signing on the dotted line!

Worldpay does also offer a pay as you go service, but be aware that your transactions will be subject to a pretty chunky charge of 2.75% plus 20p.

• Contract: 18-month minimum
• Exit fee: Yes
• Highest processing fee: 2.75% + 20p on the pay as you go plan
• Lowest processing fee: 0.75% for Debit cards on the pay monthly plan
• Setup fee: None
• Monthly fee: £40
• POS hardware costs: Pay monthly
• Free trial or plan: None

Why is Worldpay a top provider for my business?

Worldplay is a great option if you’re a more established small business looking to get the best rates possible, and you don’t mind being tied into a longer contract. It’s best suited to infrequent but high cost transactions – for example, selling luxury items – as you’ll benefit from the minimal percentage charged per sale.

Worldpay also provides its payouts within one business day, plus the option to customise your deposit schedule. If you’re a business with a lower annual turnover though, Worldpay’s fee structure could cost you more and lock you into an extended contract. Take a look at a more new starter-friendly provider like Square instead.

Worldpay countertop terminals and mobile card readers suit almost any business (the strength of Worldpay’s hardware lies in its multiple connection types – it can receive a signal from ethernet, mobile data or wifi). So if you feel like Square is let down by its lack of mobile data connection, then Worldpay is certainly worthy of consideration.

Its range of terminals and readers are compatible with other POS software. If you were turned off by Square’s closed-loop POS system, then consider Worldpay’s range of terminals and readers are compatible with other POS software (make sure you check before signing up though).

Our testers were hugely impressed by Worldpay’s robust range of 24/7 help and support covering: phone, email, live chat, and a knowledge centre. The forum where we could interact with other merchants to discuss queries and pain points was a particular bonus overlooked by every other provider on this list except Square.

Bottom line, if you’re a business dealing in high value transactions that wants the stability of a single provider with low transaction rates, and the peace of mind of 24/7 support then Worldpay could well be your ideal solution. Just be aware you’ll be locked into a contract for an extended period of time.

What our researchers think

I’m really impressed by Worldpay and would 100% recommend them for rapidly growing or established businesses looking to take online payments. They’re such a powerhouse in this world that they have so many great features such as pay by link which is great for on-the-go merchants as well as next day payouts and huge dashboard to closely analyse your best payment methods.

Buying guide: how to choose a merchant service provider

Choosing the right merchant service provider can significantly impact your operations and bottom line. Here are the essential factors to consider:

Payment options

Consider the variety of payment methods the provider supports. Whether you take payments in person, over the phone, or online, your checkout needs to be where your customers are to ensure you’re making it as easy as possible for them to spend their money with you.

For example, if an interested buyer finds your business online but has to visit your shop to make a purchase, this might end up costing you a customer.

Transaction fees

Transaction fees can vary widely and fluctuate, so make sure you’re aware of how much you’re being charged when a customer makes a payment – it could impact your profit margin.

Look for transparent pricing models with competitive rates and keep an eye out for common hidden charges that might inflate costs over time, such as contract termination fees or penalties for having insufficient funds.

Contract lengths

Evaluate the flexibility of the provider’s contract terms. Some providers lock businesses into lengthy contracts, which could mean you’re stuck paying higher fees if you spot a rival merchant provider with a more competitive rate.

Opting for a brand that offers reasonable contract lengths with the option for shorter terms or no long-term commitment can be a good way to hedge your bets.

Accepted payment types

Ensure that the provider supports the payment methods your customers prefer. Whether it’s credit or debit cards, mobile payments, contactless, or digital wallets, a comprehensive range of accepted payment methods can broaden your customer base and increase sales opportunities.

Features

Assess the additional features offered by the provider beyond basic payment processing. There are all manner of helpful add-ons you might not be aware of that make the difference between a happy or dissatisfied customer. Look for functions such as:

• Mobile payment/contactless card acceptance
• Fast processing times
• Robust security measures
• Invoicing features
• Inventory management
• Fraud protection
• 24/7 customer support
• Educational resources
• Marketing tools

Compliance measures

Verify that the provider adheres to industry regulations and standards for data security and compliance. PCI DSS (Payment Card Industry Data Security Standard) compliance is essential.

Help and support

Look for providers with accessible customer service channels (such as email, live chat, and phone support) as well as customer forums to find out how a provider performs straight from the horse’s mouth or in an emergency such as a signal error or transaction delay.

Integrations

Keeping track of your myriad tech products is easier if your business software can integrate, sharing data between applications and creating one unified system to run things from.

How much should I pay for a merchant service?

Throughout this guide we refer to several types of fees that are charged by merchant service providers. These can vary greatly depending on factors like your business size, industry, transaction volume, and chosen provider.

However, here’s a breakdown of the most common payment processing costs incurred by UK sellers and why you must pay them:

• Transaction fees = every time a customer makes a payment to your business (whether in person or online) you will need to pay a fee to the payment processor. This is usually between 1.5% and 3.5%
• Card machine/reader fees = the cost of a card machine or reader varies, with basic readers starting at around £20 and advanced models reaching over £300. Some providers offer free readers with their plans
• Virtual terminal fees = virtual terminal fees are paid when you accept a customer’s payments through a virtual terminal (over the phone, or via email or online form). They are typically a percentage, and range from 2% to 4% per transaction
• Payment gateway fees = paid when your customers buy something online, this fee covers the cost of the gateway’s technology and services. It is usually around 0.5% to 1.5% per transaction. Some gateways charge a monthly subscription fee, ranging from £10 to £50+

You may also be charged additional fees such as chargeback fees (when a customer disputes a transaction) or settlement fees (usually 20p to 50p) for transferring funds to your bank account.

How we test card processing products and merchant services for small businesses

We are rigorous. We tested 26 merchant services, evaluating them on four key criteria for UK-based small businesses. We conducted 45 tests over 22.5 hours in total, completing a total of 270 different evaluation tasks.

We explored 78 areas of investigation across 23 subcategories, under four main weighted categories. This is to ensure rankings are based on the most helpful insights to our readers.

Our main testing categories for merchant service providers are:

Card machines: Evaluating their charging power, receipt printing, connectivity, and interface. We also determine their usability based on two factors: how likely we are to recommend the product and the results of our user testing.

Software: Assessing suitability for POS integration, as well as how the provider handles payouts, the data and reporting available, which payment types are accepted, what security measures are offered, and more.

Help and support: Appraising the type, availability, and accuracy of the support the platform provides for its merchants.

Pricing: Assessing the transaction fees, contract costs, monthly costs, and upfront fees that the providers charge.
