Libby James is the founder and Managing Director of Merchant Advice Service. Since 2016, she has worked directly with businesses and payment providers across merchant accounts, card processing, payment gateways and complex provider requirements.
Libby specialises in high-risk, declined and harder-to-place merchants, as well as businesses requiring specialist payment methods, integrations or international support. She writes and reviews Merchant Advice Service content, drawing on practical experience gained from real merchant enquiries and provider relationships.
Choosing a payment provider should involve more than comparing transaction fees.
The right provider depends on how your business takes payments, what you sell, your transaction values, processing volume, integrations, customer locations, currencies, settlement requirements and the type of support you need.
For some businesses, the choice is straightforward.
For others, particularly businesses with complex integrations, international customers, higher-risk sectors, subscription models or unusual payment flows, the number of suitable providers can reduce considerably.
Merchant Advice Service helps UK businesses research and compare payment options based on what the business actually needs.
You can explore providers using The Payments Directory® or ask MAS for help narrowing down the options.
Before comparing companies, establish what part of the payment process you actually need.
The terms payment provider, merchant account, payment gateway and payment processor are often used interchangeably, but they can describe different services.
If you want to accept card payments, you need an acquiring arrangement that allows those transactions to be processed and settled to your business.
The provider will also decide whether it is willing to support your:
Business sector
Merchant Category Code
Transaction profile
Countries
Processing volume
Payment model
This becomes particularly important for businesses requiring high-risk merchant accounts.
A payment gateway provides the technology used to securely pass online payment information between your website, customer and payment infrastructure.
Gateway selection becomes particularly important where you need:
Ecommerce integrations
APIs
Recurring payments
Tokenisation
Multiple currencies
Marketplace payments
Split payments
Alternative payment methods
Complex reporting
See our Payment Gateways Guide.
Businesses accepting payments face to face may need a countertop, portable or mobile card terminal.
Compare more than the terminal itself.
Look at:
Transaction pricing
Monthly rental
Contract length
Connectivity
Settlement
EPOS compatibility
Support
Explore our Card Machine Guides.
Retail, hospitality and other physical businesses may need their payments integrated with wider point-of-sale technology.
This could include:
Till systems
Stock management
Table management
Customer data
Reporting
Accounting integrations
Explore EPOS & POS.
A merchant account and payment gateway do different jobs.
The merchant account or acquiring relationship determines whether your business can accept card transactions and receive settlement.
The payment gateway provides the technology used to transmit online payment information.
Some payment providers package both together.
Others allow businesses to use a gateway independently from the acquiring relationship.
This distinction becomes especially important for businesses with more complex payment requirements.
A gateway might have the perfect integration for your website while the acquirer behind it does not support your business sector.
Likewise, an acquirer may be willing to support your business but require you to use a compatible gateway.
For more complicated businesses, technical suitability and acquiring suitability both need to be considered.
Start with the requirements of the business rather than a list of provider names.
There are several areas worth comparing.
This should come before price.
Payment providers have different underwriting criteria.
A provider may restrict:
Certain sectors
Particular products
Merchant Category Codes
Countries
High transaction values
Future-delivery businesses
Subscription businesses
Particular payment flows
This is why a provider that works well for one merchant may be completely unsuitable for another.
Businesses operating in sectors such as travel, gambling, crypto, financial services, CBD or other specialist areas may need a provider with more specific risk appetite.
Transaction rates are important, but they are only part of the total cost.
Depending on the provider, you may also pay:
Per-transaction fees
Gateway fees
Monthly fees
Card machine rental
PCI fees
Authorisation fees
Refund fees
Chargeback fees
Cross-border charges
FX charges
Settlement fees
Minimum monthly charges
Additional MID fees
Early termination charges
Two providers quoting similar transaction rates can therefore have very different overall costs.
For larger businesses, the pricing structure itself can also matter.
You may be offered:
Blended pricing
Interchange Plus
IC++
Fixed pricing
Bespoke enterprise pricing
Compare the full cost of processing, not just the headline percentage.
Settlement determines how quickly processed funds reach your business bank account.
Providers may offer different arrangements depending on the merchant.
Consider:
Standard settlement time
Weekend settlement
International settlement
Settlement currencies
Minimum settlement amounts
Reserve requirements
Circumstances where funds can be held
Cash flow can make settlement just as important as transaction pricing for some businesses.
Before changing provider, understand the contract you are entering into.
Check:
Minimum contract period
Notice requirements
Automatic renewal
Early termination fees
Hardware agreements
Minimum processing commitments
Price-review clauses
A low introductory transaction rate can become considerably less attractive if the wider contract is unsuitable.
If payments need to connect to other software, start with the integration requirement.
You may need compatibility with:
Shopify
WooCommerce
Magento
A custom website
Booking software
CRM
ERP
Accounting software
Subscription platforms
Mobile applications
Your own SaaS platform
An attractive payment provider is not much use if it cannot work with the systems your business relies on.
For more complex integrations, explore our Payment Gateway Guides.
Subscription businesses have additional requirements.
Look at:
Recurring transaction support
Tokenisation
Stored payment credentials
Failed-payment recovery
Account updater services
Reporting
Cancellation management
International billing
Multiple currencies
Read our guide to Subscription Payment Processing.
Selling internationally introduces another set of questions.
Do not simply ask whether the provider accepts overseas cards.
Consider:
Customer countries
Acquiring location
Presentment currencies
Settlement currencies
FX costs
Cross-border charges
Local acquiring
Local payment methods
International entities
Read our guides to International Merchant Accounts and Multi-Currency Merchant Accounts.
Marketplaces and platforms often need more than straightforward ecommerce processing.
A business may need to:
Accept money from customers
Split funds
Pay multiple sellers
Deduct fees or commission
Manage refunds
Verify sellers
Support different settlement structures
This can create both technical and regulatory considerations.
Read our guides to Marketplace Payment Gateways and Split Payment Gateways.
If you are specifically comparing gateways, look at the features your business will actually use.
These might include:
Hosted checkout
Embedded checkout
Payment links
In-app payments
Ecommerce platforms
Booking systems
ERP
CRM
Accounting
Custom API
Visa
Mastercard
American Express
Apple Pay
Google Pay
Alternative payment methods
Bank payments
Tokenisation
Subscription billing
Stored credentials
Failed-payment recovery
Multiple currencies
International acquiring
Local payment methods
Cross-border processing
3D Secure
Fraud tools
PCI support
Tokenisation
Settlement reporting
Reconciliation
Refunds
Chargebacks
Multi-entity reporting
The gateway with the longest feature list is not necessarily the most suitable.
The important question is whether the provider supports your required payment journey.
High-risk payment comparison works slightly differently.
The first question is usually not:
Which provider is cheapest?
It is:
Which providers are willing and able to support the business?
A high-risk provider may assess:
Merchant Category Code
Business model
Company history
Director and UBO information
Processing history
Chargeback levels
Transaction values
Customer countries
Regulatory status
Delivery times
Refund exposure
Website
Payment flow
Once suitable providers have been identified, commercial terms can then be compared.
Read our High-Risk Merchant Accounts Guide.
Do not immediately submit applications to several more providers.
First try to understand why the application was declined.
The reason could be:
Sector appetite
Merchant Category Code
Customer countries
Transaction values
Insufficient trading history
Documentation
Chargeback exposure
Regulatory requirements
Integration
Provider policy
Once the reason is understood, it becomes easier to identify providers whose criteria may be different.
Read What to Do If You've Been Declined for Card Processing.
Businesses change payment providers for many reasons.
You may have:
Outgrown your existing provider
Increased your transaction volume
Added new payment methods
Expanded internationally
Changed ecommerce platform
Developed new integrations
Started subscriptions
Experienced poor support
Seen costs increase
Changed business model
Before switching, compare what the new provider will actually improve.
Also check your existing:
Contract
Notice period
Terminal agreement
Gateway setup
Stored payment tokens
Recurring payments
Integrations
Settlement arrangements
Changing provider can involve more than changing the transaction rate.
Different merchants should prioritise different things.
Consider:
Gateway integration
Checkout
Fraud
Wallets
Refunds
Settlement
Consider:
Recurring payments
Tokenisation
Account updater
Failed-payment recovery
International billing
Consider:
Split payments
Seller onboarding
Settlement
Compliance
APIs
Consider:
Acquiring countries
Customer countries
Currencies
FX
Local payment methods
Consider:
Sector appetite
MCC
Underwriting
Chargebacks
Reserves
Countries
Consider:
IC++ or Interchange Plus
Scheme fees
Acquiring structure
Authorisation performance
Cross-border costs
Settlement
Consider:
APIs
Existing integrations
Token portability
ERP
CRM
Reporting
Payment orchestration
This is why a generic "top ten payment providers" list will not always produce the right answer.
There are several situations where price should not be the only consideration.
For example:
Provider A: 0.9% processing fee but cannot integrate with your booking system.
Provider B: 1.0% processing fee and integrates directly.
Provider B may create the better overall business outcome.
Similarly:
Provider A: lower transaction cost but converts all international revenue into GBP.
Provider B: slightly higher transaction rate but allows EUR and USD settlement.
For a merchant with significant international turnover, the second proposition could potentially be more commercially suitable.
Payment comparison is therefore about total payment economics and operational fit, not one number.

How Merchant Advice Service Works
How MAS provides guidance, provider matching and introductions.
Merchant Advice Service is not tied to one payment provider. Businesses do not pay Merchant Advice Service to use its information, matching or introduction service. MAS may receive a referral fee or commission from a partner when an introduction results in a completed account, product or service.
Merchant Advice Service does not necessarily compare every provider in the market. Provider suitability is considered according to the information supplied by the business and the provider's current criteria. Final acceptance, underwriting, pricing and contractual terms remain with the payment provider.
This page provides general payment information and does not constitute legal, regulatory, financial, accounting or tax advice. Businesses should review provider terms carefully and obtain appropriate professional advice where required.
