If you’re a business owner thinking about how to accept card payments, you’ve likely stumbled upon the term “merchant service provider” (MSP). MSPs are the middlemen between you, the banks, and your customers. They help you process card payments smoothly so you can focus on running your business.

But what makes one MSP better than another? It’s not just about the fees. You also need to consider the contract terms, customer service, and whether the MSP is a good fit for your specific business needs. Many of them supply hardware, like card readers, too.

My comprehensive guide will walk you through everything you need to know about MSPs, from choosing the right one to understanding the nitty-gritty of contracts and customer service.

The Best Merchant Service and Credit Card Processing Companies for Small Business

As a business payments expert, I’ve spent a lot of time analysing the merchant service companies best suited for UK businesses to accept card payments. This means going deeply into what they offer, their costs and contractual requirements, and then actively testing their units.

Overall, Square gets my vote as the best merchant services provider with its well-designed, affordable hardware, sophisticated App, and no contract pricing. The app has over 10 million downloads and a 4.7-star rating on Google Play.

At the low-to-mid level, I like brands like Takepayments, Yuma POS and Barclaycard. These brands offer a decent blend of contract length, hardware and software functionality combined with fair pricing.

For larger retail or hospitality businesses, including those with chains, I think Lightspeed is a great solution. It’s highly customisable and has impressive functionality to streamline major operations.

If you’re a high-volume merchant or in any kind of higher-risk category, Manchester Fintech Total Processing would be a top choice. Their efficiency, customer service and technical acumen, combined with an incredible breadth of payment options, really make them stand out.

These services are designed to make the transaction process smooth, secure, and efficient for both you and your customers.

How to Choose the Right Merchant Service Provider

Choosing a merchant service provider is a big decision that can have a significant impact on your business operations and customer experience. Choose the wrong one and you might find yourself stuck in a lengthy contract or paying over the odds with every sale, so you want to get it right.

I recommend focussing on these key criteria when making your choice:

  • Reliability: The provider should offer reliable operational services when you need them most. Downtime during peak business hours can result in lost revenue and damage your reputation.
  • Security compliance: With increasing threats to data security, it’s essential that your provider adheres to industry standards such as PCI DSS compliance.
  • Range of services: Assess the variety of services on offer. Does the provider offer just payment processing, or do they have a range of services like virtual terminals, mobile payments, and e-commerce solutions?
  • Flexibility and scalability: As your business grows, your needs will change. A good merchant service provider should offer flexible solutions that can scale with your business.
  • Fee structure: Transparent and reasonable fees are crucial. Look for providers that offer straightforward pricing without hidden charges. Compare setup fees, transaction fees, and any other associated costs.
  • Customer support: Effective and responsive customer support can be a lifesaver, especially when facing technical issues. Ensure the provider offers multiple channels for support, including phone and email, and check their availability during your business hours.
  • Contract terms: Be cautious of long-term contracts that are difficult to exit. Some providers may offer lower fees in exchange for long-term commitments; ensure you read the fine print and understand the terms.
  • Industry-specific features: Some providers offer solutions tailored to specific industries. Whether you’re in retail, hospitality, or any other sector, look for features that align with your industry’s unique needs.
  • Integration capabilities: Ensure that the provider’s system can integrate seamlessly with your existing business software, such as accounting packages or CRM systems, to streamline operations.
  • Reviews and recommendations: Lastly, consider reviews and testimonials from other businesses. Peer recommendations can provide valuable insights into a provider’s reliability and service quality.

How Does a Merchant Services Provider Work?

The operational workflow of an MSP is typically as follows:

  1. Payment Gateway: The payment gateway serves as the first point of contact in the transaction process. It securely captures and transmits card details from the customer to the payment processor.
  2. Payment Processor: Once the payment gateway captures the information, the payment processor validates the details against the customer’s bank and either approves or declines the transaction.
  3. Merchant Account: A merchant account is a special type of bank account that temporarily holds funds from card transactions. Once the transaction is approved, the funds are transferred to the merchant’s business bank account, usually within a couple of business days.

Security Measures:

MSPs must implement robust security measures to protect sensitive customer data. This includes adhering to Payment Card Industry Data Security Standards (PCI DSS) and using encryption and tokenization techniques.

Reporting and Analytics:

Most MSPs offer a dashboard that allows merchants to track payments, refunds, and other transaction details. This feature is invaluable for monitoring business performance and making data-driven decisions.

Integration Capabilities:

MSPs typically offer APIs or pre-built plugins for popular software platforms, making it easy to integrate their payment processing solutions with existing systems, such as accounting software or a Customer Relationship Management (CRM) system.

Technical Support:

Reliable technical support is essential for merchants, especially when resolving issues urgently. MSPs should offer support through various channels, such as email, phone, or live chat.

Merchant Services Fee Structures and Contractual Considerations

Selecting a merchant service provider (MSP) is a significant business decision, and it is important to understand the financial and contractual commitments involved. Here are some key points to bear in mind when evaluating fee structures and contracts:


  • Initial setup and installation fees: MSPs often charge an upfront fee for setting up your merchant account and installing any required hardware. These fees can vary widely, so it is important to compare costs across providers.
  • Transaction fees: A critical component of the fee structure is the transaction fee, which is usually a percentage of the transaction amount, sometimes coupled with a flat fee per transaction. This fee can differ depending on the type of payment method used.
  • Monthly and annual fees: In addition to transaction fees, MSPs may charge monthly or annual service fees. These fees can cover a range of services, such as data analytics, customer support, and software updates.
  • Termination fees: Long-term contracts may include a termination fee for exiting the contract before the agreed period. Carefully review the contractual terms to understand your obligations and potential costs for early termination.
  • Additional charges: Some MSPs levy additional charges for services like chargeback handling, international transactions, or advanced reporting features. Be aware of these potential costs when evaluating providers.

Contractual Considerations:

  • Transparency and fairness: The MSP should offer a transparent fee structure without hidden costs. Unexpected fees can significantly impact your overall costs and disrupt financial planning.
  • Contract flexibility: Consider the contract length and terms of renewal. MSPs that offer flexible contracts enable you to adapt to changing business conditions, rather than locking you into long-term commitments that may not serve your future needs.
  • Negotiation possibilities: Lastly, don’t hesitate to negotiate fees and contract terms. MSPs may be willing to offer customized packages or discounts, especially if you anticipate a high volume of transactions.

The Cheapest Merchant Services For Small Businesses

The true ‘cheapest’ merchant services for any business will depend on your turnover, credit history, sector and average transaction value, to name a few of the variables.

It is also true that, for small businesses with lower sales amounts, a pricing structure that initially seems expensive (like Square’s 1.75% blended transaction fee) could work out as more affordable than providers who charge lower transaction fees but have monthly fees. The kind of payment cards accepted and the contract length also affects the overall costs. We recommend Square for businesses turning over £5k per month or less.

Above that threshold, Take Payments ranks as one of the cheapest providers across a variety of scenarios with its bespoke pricing allowing for negotiations based on individual business requirements and transaction volumes.

Yuma POS payments are also very competitive on a per transaction rate, as is Barclaycard Payments and Natwest Tyl.
