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.
Most payment-provider comparisons start with price.
We think that is the wrong place to start.
A payment provider can offer an excellent transaction rate and still be completely unsuitable for your business.
It may not:
So before asking:
“Who is cheapest?”
Merchant Advice Service starts with a different question:
“Who can actually support this business?”
That is the thinking behind The Payments Directory®.
The Payments Directory® is a payment-provider research and matching platform operated as part of Merchant Advice Service.
It was developed to help businesses narrow down payment providers according to their actual requirements rather than simply comparing headline transaction rates.
Businesses can be matched using criteria including:
The merchant can then decide which provider or providers they want to speak to.
The service is free for merchants to use.
Merchant Advice Service was founded in 2016 after identifying a lack of simple, non-biased information in the payments market. The Payments Directory® developed from the same problem: businesses needed a better way to work out where they actually fitted before applying.
Payments are sometimes presented like a commodity.
Provider A charges X.
Provider B charges Y.
Choose the cheapest.
In reality, payment providers have different:
A restaurant looking for two card machines is not the same requirement as a travel company taking £5,000 deposits nine months before departure.
Neither is comparable with:
They may all technically be looking for payment processing.
But they should not necessarily be looking at the same providers.
We think payment-provider comparison works better when it happens in this order:
Look at:
sector + risk + MCC + geography + payment method + technology + transaction profile
Then compare:
processing cost + payment performance + settlement + reserve + contract + support + functionality
Doing those stages the other way around can create problems.
A 0.3% cheaper provider isn't cheaper if it declines the application.
And an approved provider isn't necessarily the best choice simply because it was the first one willing to say yes.
This is the basic methodology behind The Payments Directory®.
This sounds obvious.
It isn't.
“Ecommerce” tells us almost nothing.
Consider:
UK ecommerce travel company taking £1,500 deposits for trips departing six months later.
That tells us considerably more.
Likewise:
Software company
could mean a straightforward B2B SaaS subscription business.
Or it could mean a platform that enables thousands of customers to take payments themselves.
Provider matching starts with understanding how the business actually makes money and how payment fits into it.
Merchant Category Codes help classify the type of business accepting payment.
They matter because acquiring providers and card schemes use merchant classification within payment processing and risk management.
But MCC should not become a shortcut for understanding the whole business.
Two merchants with similar classifications can still have very different:
MCC can help narrow the market.
It cannot tell the whole story.
The provider still needs to understand the merchant behind the code.
This can eliminate providers before pricing is even relevant.
Provider appetite can differ substantially in sectors such as:
Even within the same sector, appetite can vary.
For example:
UK-licensed gambling
is not necessarily treated the same way as:
international gambling across multiple jurisdictions.
And:
high-street pharmacy
is not the same payment proposition as:
online prescribing + dispensing + delivery.
The Payments Directory® is intended to make those distinctions more useful than simply categorising everything as “high risk”.
Payment method matters.
A merchant may require:
That requirement can immediately change the shortlist.
For example, a provider suitable for a conventional card-present retailer may not necessarily be the best fit for a business requiring:
customer-initiated first payment → stored credential → merchant-initiated recurring transactions
Likewise, a high-value merchant may need a provider comfortable with £20,000+ transactions rather than simply one offering a standard ecommerce gateway.
This is one of the most overlooked parts of payment comparison.
A provider can be:
and still be useless if it doesn't work with the technology the merchant needs.
Integrations can include:
Suppose:
Provider A costs £800 less per month
but doesn't integrate with the merchant's booking system.
The business then needs:
That £800 “saving” may disappear very quickly.
This is why The Payments Directory® treats integration as part of provider suitability, not an optional question to ask after a quote has arrived.
A UK company does not necessarily have UK-only payment requirements.
It might have customers across:
Likewise, a European merchant might have substantial UK activity.
Provider matching can therefore need to consider separately:
Where is the merchant incorporated?
Where are its directors?
Where are its customers?
Where is payment activity taking place?
Where does it want to expand next?
The Payments Directory® includes location and geographic criteria because a provider's ability to support one country does not automatically mean it supports every market the merchant needs.
Turnover alone isn't enough.
Useful information can include:
Consider:
£500,000 monthly card turnover made up of £30 transactions.
£500,000 monthly turnover made up of £10,000 transactions.
£500,000 collected today for travel taking place months later.
Same turnover.
Very different acquiring profiles.
Not every merchant needs “a new provider”.
The real problem might be:
Our current rate is too high.
or:
Our £20,000 transactions keep declining.
or:
Our gateway won't integrate with the new booking platform.
or:
We need EUR and USD settlement.
or:
Our reserve no longer reflects the size of our business.
or:
We want to embed payments into our SaaS platform.
or:
Our merchant account has been terminated.
The solution should start with the problem.
This is particularly important for businesses with more complex requirements.
A merchant applies to Provider A.
Declined.
Provider B.
Declined.
Provider C.
Declined.
At this point the sensible question is not:
“Who else can we apply to?”
It is:
“Why are these applications being declined?”
Possible reasons could include:
Matching is especially valuable here because the objective should be to approach providers where there is a credible fit, not simply generate a longer list of applications.
The Payments Directory® does not guarantee approval.
Underwriting remains with the provider.
There is a tendency in payments to treat ten applications as better than two.
We don't think that is necessarily true.
For a complex merchant, we would rather identify:
two providers with genuine appetite
than:
ten recognisable brands that are unlikely to support the requirement.
That is the difference between provider discovery and provider matching.
An established merchant processing:
£500,000 or £1m+ per month
may already have a perfectly functioning payment provider.
Its problem might be optimisation rather than acceptance.
The matching process can therefore start with:
Only then does it make sense to compare alternatives.
For a substantial merchant, changing payment provider to save a few basis points can be a poor decision if it damages:
The difference is that, for an established merchant, commercial performance becomes part of suitability.
Once we know which providers can realistically support the requirement.
Then price absolutely matters.
Depending on the merchant, that might include:
But the meaningful comparison is between appropriate providers.
Not every provider on the market.
The principle is deliberately simple.
This might include:
sector + location + payment requirements + turnover + integrations + currencies
The Payments Directory® uses the merchant's requirements to identify relevant providers from the information available within the platform.
The merchant can look at the providers that appear relevant to its requirements.
The merchant remains in control of which provider or providers it wishes to explore further.
Where the merchant proceeds, the relevant payment provider conducts its own underwriting and makes the final decision on:
The Payments Directory® does not replace provider underwriting.
Transparency matters here.
Final approval always remains with the provider.
We can help identify potential fit. We cannot approve an application on a provider's behalf.
The Payments Directory® is a researched provider-matching resource rather than a claim to represent every possible payment provider globally.
Pricing is one part of the comparison.
Where a merchant's business model raises regulatory questions, appropriate professional advice may still be required.
Merchant Advice Service has worked with businesses looking for payment solutions since 2016.
Over that time, one problem has appeared repeatedly.
Businesses often start the payment search with a brand name or price.
They ask:
“Should I use Provider A or Provider B?”
before establishing whether either provider is appropriate.
For more complex merchants, the question should often come one stage earlier:
“What type of provider actually fits this business?”
The Payments Directory® was created to make that first stage easier.
Instead of:
provider → merchant tries to fit provider
we want the process to be:
merchant requirement → suitable provider options
Some merchants have straightforward requirements.
They may be perfectly comfortable researching their options themselves.
Others don't.
For example:
Those businesses may need a conversation before provider matching makes sense.
That's why Merchant Advice Service combines self-serve provider research with specialist support for more complex requirements. The existing MAS site positions the directory around both self-service provider discovery and tailored matching against factors such as MCC, integrations, location, currencies and payment methods.
This is something a pure lead-generation form struggles to do.
A merchant may need to:
before approaching another provider.
Sending the application immediately may create another decline.
Good provider matching sometimes means slowing the application down first.
The Payments Directory® is free for merchants to use.
Merchant Advice Service is a commercial business.
Where a merchant chooses to proceed with a provider introduced through MAS, Merchant Advice Service may receive a referral fee, commission or ongoing commercial payment from that provider.
This does not change the principle behind the matching process:
provider suitability should be based on the merchant's requirements, not simply on the cheapest advertised price or the size of an available commission.
Merchants remain free to decide whether they want to proceed with any provider introduced through MAS.
The Payments Directory® is part of Merchant Advice Service, founded by Libby James in 2016.
Libby's work focuses particularly on:
The Payments Directory® developed from MAS's experience of helping merchants work out where to apply and why, rather than simply giving businesses another list of payment companies.
A payment provider that works brilliantly for another business may be completely wrong for yours.
Start with:
what you sell
how customers pay
where they are
what technology you use
how much you process
and:
what you need the payment provider to do
Then compare the providers capable of supporting that requirement.
That is the approach behind The Payments Directory®.
Merchant Advice Service provides free, independent guidance to businesses looking for help with card payments, payment gateways and more complex payment requirements.
Where appropriate, MAS may introduce a business to a relevant payment provider. We may receive a referral fee or commission if an introduction results in a completed account or service.
MAS does not necessarily compare every provider in the market, and all applications remain subject to the relevant provider's own assessment, underwriting and approval.
