Payment Provider Risk Appetite: Why Acquirers Accept Different Businesses UK

Payment-provider risk appetite describes the types of merchants, business models and payment risks that a payment provider or acquiring bank is willing to support.

This is why two payment providers can review the same legitimate UK business and reach different decisions.

One acquirer may accept the merchant.

Another may request additional information or a rolling reserve.

Another may decide the business falls outside its current acceptance policy altogether.

Provider appetite can depend on factors including:

• Merchant Category Code (MCC);
• products and services;
• business model;
• business location;
• customer geography;
• monthly processing volume;
• average and maximum transaction values;
• future-delivery exposure;
• chargebacks and refunds;
• fraud exposure;
• financial strength;
• trading history;
• previous card-processing history;
• regulation and licensing;
• how customer money moves;
• payment channels;
• technical integrations; and
• the provider's underlying acquiring relationships.

Risk appetite can also change over time.

A business accepted by a provider several years ago should not automatically assume that the same provider would accept an identical new merchant today.

This guide explains what payment-provider risk appetite means, why acquiring banks accept different businesses, how provider policies interact with MCC, underwriting and card-scheme rules, why legitimate merchants can still be declined, and how businesses can compare provider fit before applying.

Quick Summary

• Payment providers do not all accept the same businesses.
• There is no universal merchant-acceptance policy shared by every UK acquirer or PSP.
• “Risk appetite” is useful payments-industry terminology rather than one universal FCA merchant-risk classification.
• The FCA regulates merchant acquiring as a payment service, but individual providers still make their own merchant-underwriting and acceptance decisions.
• Provider appetite can depend on MCC, business activity, transaction values, geography, processing history, future delivery, financial strength and other factors.
• A legal business can still fall outside a payment provider's acceptance policy.
• Restricted does not always mean prohibited: some providers accept certain activities only after additional underwriting.
• A provider supporting an industry does not automatically mean it supports every business model within that industry.
• A provider supporting a merchant today does not guarantee that its appetite will remain unchanged indefinitely.
• Underlying acquiring banks, card networks, payment methods and financial partners can influence what a PSP can support.
• A PSP, PayFac, acquirer and payment gateway do not necessarily have identical roles or identical risk appetite.
• MCC is an important classification signal, but it does not determine acceptance by itself.
• Future-delivery exposure can materially alter provider appetite even where the merchant's sector is otherwise acceptable.
• Regulatory authorisation can support underwriting where relevant, but it does not guarantee payment-provider acceptance.
• Strong processing history can improve the evidence available to an underwriter but does not create automatic approval.
• A payment provider can potentially impose reserves, settlement controls or processing limits instead of simply accepting or declining the merchant on standard terms.
• Provider appetite should therefore be considered before price.
• Merchant Advice Service's 2026 onboarding research found that 41% of 25 payments-industry respondents identified poor provider or risk fit as a contributor to merchant-account declines.
• The practical question is not simply “Who has the lowest processing rate?” but “Which providers currently fit this merchant?”

What Is Payment Provider Risk Appetite?

Risk appetite is the level and type of merchant risk that a payment provider or acquiring bank is willing to take.

For merchants, this affects questions such as:

• Will the provider accept our business?
• Will additional underwriting be required?
• Will the provider support our MCC?
• Will it support our countries and currencies?
• Will it accept our transaction values?
• Will it support our future-delivery exposure?
• Will it require a reserve?
• Will it impose processing limits?
• Will it support the required gateway or integration?
• Will the commercial terms be workable?

Risk appetite should not be confused with whether a business is legal.

A business can operate lawfully and still fall outside a particular provider's commercial or underwriting criteria.

Stripe's current UK guidance, for example, explicitly explains that certain legal activities remain unsupported because of factors including requirements applying to Stripe, requirements from financial partners and potential financial risk exposure.

Adyen similarly states that its restricted and prohibited categories are influenced by factors including law, card-network requirements, assessed chargeback and fraud risk and other internal and external obligations.

MAS View

Legal does not automatically mean acceptable to every acquirer.

Regulatory permission answers:

“Can the business lawfully perform this activity?”

Merchant underwriting answers a different question:

“Is this provider willing to process these payments on these terms?”

Why Do Different Payment Providers Accept Different Businesses?

Because providers do not all have identical:

• acquiring structures;
• risk policies;
• sector experience;
• geographical coverage;
• financial exposure;
• card-scheme programmes;
• payment-method partners;
• underwriting processes;
• technical capability;
• commercial thresholds; or
• strategic priorities.

A provider designed primarily for straightforward retail and ecommerce merchants may assess a travel company differently from an acquirer with significant experience underwriting travel portfolios.

Likewise, a provider that supports professional financial-services firms may not necessarily support customers using cards to fund investments, wallets or trading accounts.

The label describing the industry is therefore rarely enough.

MAS View

Do not ask only:

“Does this provider accept travel?”

or:

“Does this provider accept financial services?”

Ask:

“Does this provider currently support our exact activity, MCC, payment flow, transaction values, customer geography and risk profile?”

Who Actually Decides Whether a Merchant Is Accepted?

This depends on the payment structure.

The company the merchant speaks to is not always the only organisation influencing acceptance.

A payment arrangement can involve:

• the merchant;
• a payment service provider;
• an acquiring bank;
• a payment facilitator;
• a payment gateway;
• card networks such as Visa and Mastercard;
• alternative payment-method providers; and
• other financial or technology partners.

The FCA defines acquiring payment transactions as a payment service where a payment service provider contracts with a payee to accept and process payment transactions which result in funds being transferred to the payee.

Merchant acquiring can therefore involve different commercial and technical models.

Provider eligibility can ultimately reflect several layers of requirements rather than one simple company-wide list.

What Is the Difference Between an Acquirer, PSP, PayFac and Gateway?

Term	Broad Role	Risk Appetite Relevance
Acquirer	Contracts to accept and process payment transactions for the merchant.	The acquiring relationship is central to merchant underwriting and financial exposure.
PSP	Can provide a wider bundle of payment services, potentially including acquiring, gateway, payment methods and other technology.	Eligibility depends on the provider's model and its underlying acquiring/financial relationships.
Payment Facilitator	Onboards sponsored/sub-merchants within an acquiring programme.	The programme operates within its own risk policy and the requirements of its sponsoring acquirer and card networks.
Payment Gateway	Provides technology used to transmit and manage payment information.	A gateway may technically support a merchant even where the acquiring provider does not accept the business.

The FCA specifically notes that merely providing technical services such as data processing, storage, terminals or online gateways does not itself constitute acquiring.

This distinction matters.

A business can find a gateway that technically supports its website but still need an acquiring bank willing to underwrite the transactions.

Read our Payment Service Providers guide and Payment Facilitators guide for more on the different models.

Does the FCA Decide Which Merchants Payment Providers Must Accept?

No.

Merchant acquiring is a regulated payment service in the UK.

The FCA regulates payment-service providers and the regulatory framework within which they operate.

However, this does not create a universal requirement that every authorised acquirer must accept every lawful merchant.

Payment providers still undertake merchant underwriting and establish eligibility criteria within the relevant legal, regulatory, scheme and contractual framework.

MAS View

FCA regulation of the provider is not the same thing as FCA approval of the merchant.

Likewise, a merchant being FCA authorised does not mean an acquiring bank must accept its card processing.

What Factors Determine Payment Provider Risk Appetite?

There is no universal checklist applied identically by every payment provider.

However, common factors include the following.

1. Business Activity

The provider needs to understand what the merchant actually sells.

For example:

• physical goods;
• professional services;
• travel;
• financial services;
• gambling;
• software;
• subscriptions;
• digital goods;
• healthcare;
• marketplace services; or
• another product or service.

2. Merchant Category Code

The MCC helps classify the merchant's business activity.

Some providers have broader appetite for certain MCCs than others.

However, MCC should not be treated as the entire underwriting decision.

Read our Merchant Category Codes (MCC) guide.

3. Business Model

Two merchants selling similar products can operate very differently.

Examples include:

• immediate fulfilment versus future delivery;
• one-off payments versus subscriptions;
• own-product sales versus marketplace transactions;
• domestic versus international customers;
• low-value versus high-value transactions;
• card-present versus ecommerce;
• direct sales versus telemarketing; and
• merchant revenue versus money subsequently passed to another party.

4. Processing Volume

A provider may have different appetite for:

• £5,000 per month;
• £100,000 per month;
• £1 million per month; or
• £20 million per month.

Volume can affect both commercial attractiveness and financial exposure.

5. Transaction Values

A £30 average card transaction creates a different exposure profile from a £5,000 average card transaction.

Providers can consider both:

• average transaction value; and
• maximum transaction value.

6. Future Delivery

If customers pay before receiving the product or service, an acquirer may need to assess outstanding customer obligations.

Read our Future-Delivery Risk in Payments guide for worked examples.

7. Chargebacks and Refunds

Previous processing statements can provide evidence of:

• dispute levels;
• refund behaviour;
• processing stability; and
• historic card performance.

8. Financial Position

Depending on the merchant, an underwriter may consider:

• filed accounts;
• management accounts;
• bank statements;
• cash position;
• trading history;
• financial forecasts; and
• ability to meet refunds or other payment liabilities.

9. Geography

Provider appetite can vary according to:

• where the business is incorporated;
• where directors are based;
• where goods or services are supplied;
• where customers are located;
• which currencies are used; and
• which countries are involved in the payment flow.

10. Regulation and Licensing

Where relevant, providers may request evidence of:

• FCA authorisation;
• FCA registration;
• appointed-representative status;
• gambling licences;
• sector-specific licences;
• professional registrations; or
• other relevant permissions.

11. Processing History

An established merchant can potentially provide:

• historic card volume;
• refund rates;
• chargebacks;
• transaction values;
• seasonality;
• previous reserve arrangements; and
• evidence of stable processing.

12. Technical Requirements

Provider fit can also fail because the payment technology is unsuitable.

A merchant may need:

• Shopify;
• WooCommerce;
• a booking-system integration;
• custom API;
• recurring billing;
• tokenisation;
• split payments;
• marketplace functionality;
• EPOS;
• CRM integration;
• ERP integration;
• multi-MID support; or
• international acquiring.

A provider that accepts the sector but cannot support the required payment architecture is still not a good match.

Does a Legal Business Automatically Fit a Provider's Risk Appetite?

No.

This is one of the most important distinctions in payment-provider selection.

Current provider policies illustrate it clearly.

Stripe states that some businesses may be lawful but remain unsupported because of financial-partner requirements and the potential risk exposure involved.

Adyen distinguishes between:

• restricted activities that can require additional documentation or approval; and
• prohibited activities it does not support.

These are examples of provider policies rather than recommendations.

Another acquiring provider can have a different policy.

MAS View

Lawfulness establishes whether the activity can legally take place.

Risk appetite establishes whether that provider wants to process it.

The two tests should not be confused.

What Is the Difference Between Restricted and Prohibited?

Terminology differs between providers, but broadly:

Status	What It Can Mean
Supported	The provider generally supports the business type, subject to normal underwriting.
Restricted	The activity may require additional information, approval or specific conditions.
Prohibited	The provider does not support that activity under its current policy.
Case-by-case	Acceptance depends on more detailed assessment of the particular merchant.

These labels should always be checked against the provider's current policy.

They can change.

Can Two Providers Treat the Same Industry Differently?

Yes.

For example, a category could be:

Provider A → unsupported

Provider B → restricted / enhanced review

Provider C → routinely considered

That does not necessarily mean one provider is right and another is wrong.

They can have different:

• acquiring partners;
• risk expertise;
• loss tolerance;
• commercial strategy;
• scheme registrations;
• geographical permissions;
• technology;
• portfolio concentration; and
• internal underwriting policy.

Can Two Businesses in the Same Industry Get Different Decisions?

Yes.

This is equally important.

Consider two travel businesses.

Merchant A	Merchant B
15 years trading	New business
£100 average transaction	£4,000 average transaction
30-day average future delivery	9-month average future delivery
Strong previous processing history	No previous processing history
Low historic disputes	No historic dispute data
Strong balance sheet	Limited financial evidence

Both could share the same broad sector or MCC.

The risk profile is different.

MAS View

Sector ≠ complete risk profile.

This is why searching for “a provider that accepts travel” or “a high-risk gateway” is only the first stage.

Does MCC Determine Provider Risk Appetite?

It can influence it, but not determine it alone.

MCC gives the provider a classification signal.

It does not tell the provider:

• how long the merchant has traded;
• how much it processes;
• how large its transactions are;
• how many customers dispute payments;
• how long customers wait for fulfilment;
• how strong the merchant is financially;
• where customers are located;
• which licences the merchant holds; or
• whether the technical setup is suitable.

Visa's merchant-risk framework also requires acquirers to operate merchant underwriting and exposure controls rather than relying on a category code alone.

See our MCC & High-Risk Merchant Category Code guide.

Does FCA Authorisation Guarantee Provider Acceptance?

No.

This is especially relevant to financial-services merchants.

FCA authorisation or registration can provide useful underwriting evidence where it applies.

It can help establish:

• the regulated legal entity;
• the activities it is permitted to conduct;
• its regulatory status;
• relevant permissions; and
• whether the business description appears consistent with its regulatory position.

But the payment provider can still separately assess:

• what the customer is paying for;
• how funds move;
• MCC;
• customer geography;
• transaction values;
• chargebacks;
• processing history;
• commercial exposure; and
• its own appetite.

Our Financial Services Merchant Accounts guide explains this in more detail.

Why Does the Payment Flow Affect Risk Appetite?

The same company can potentially create very different payment requirements depending on what happens to customer money.

Compare:

Customer pays merchant £500 for the merchant's own professional service.

with:

Customer pays merchant £500 and the merchant subsequently transfers some or all of that money to another party.

The second arrangement can involve a materially different payment structure.

This becomes particularly important for:

• marketplaces;
• platforms;
• booking services;
• financial services;
• aggregators;
• split payments; and
• other multi-party payment flows.

The FCA warns that businesses receiving customer money before passing it to sellers can potentially be providing regulated payment services.

MAS View

For complex businesses:

map the funds flow before choosing the provider.

The right provider depends not only on what the merchant sells, but who receives and controls the customer's money.

Why Does Future Delivery Change Provider Appetite?

Future delivery can create financial exposure after settlement has already reached the merchant.

A provider may therefore want to understand:

• amount collected in advance;
• average fulfilment period;
• maximum fulfilment period;
• outstanding customer obligations;
• peak seasonal exposure;
• refunds;
• chargebacks;
• financial strength; and
• ability to continue fulfilling customers.

A provider with little appetite for long future-delivery exposure may decline a merchant another specialist acquirer is prepared to consider.

See our Future-Delivery Risk in Payments guide.

Can Strong Processing History Change Provider Appetite?

It can materially improve the evidence available to underwriting.

An established merchant can often demonstrate:

• historic processing volume;
• average transaction values;
• refund levels;
• chargebacks;
• seasonality;
• previous reserve terms;
• settlement history; and
• how the business has performed over time.

That is different from a new merchant providing only forecasts.

However, strong processing history does not guarantee acceptance.

A provider may still decide that the:

• sector;
• business model;
• geography;
• regulatory position;
• future exposure; or
• technical requirements

fall outside its current policy.

Can Provider Risk Appetite Change?

Yes.

Risk appetite should not be treated as permanent.

A provider can change:

• sector acceptance;
• country appetite;
• transaction-value limits;
• future-delivery tolerance;
• financial requirements;
• reserve policy;
• supported payment methods;
• underlying acquiring relationships;
• scheme requirements; or
• commercial strategy.

A provider may therefore stop onboarding new merchants in a category that it previously accepted.

Existing merchants can also be subject to ongoing risk review.

Can a Payment Provider Terminate a Merchant Because Its Risk Appetite Changes?

Potentially, subject to the merchant agreement and circumstances.

A merchant can potentially remain compliant with its historic processing arrangement but no longer fit the provider's current commercial or risk position.

This is different from termination caused by fraud, excessive disputes or a serious merchant-agreement breach.

Our Terminated Merchant Facilities guide explains the different potential causes of merchant-account closure and what businesses should establish before applying elsewhere.

MAS View

If an account closes because the provider changed appetite, explain that accurately to the next acquirer.

“Our previous provider no longer supports the sector”

is materially different from:

“The account was terminated following excessive fraud or a scheme violation.”

Can a Provider Accept a Merchant but Apply Different Terms?

Yes.

Merchant underwriting is not always simply:

approve / decline.

A provider might potentially approve a merchant subject to:

• a rolling reserve;
• a fixed reserve;
• delayed settlement;
• a processing cap;
• a maximum transaction value;
• additional monitoring;
• specific countries being excluded;
• particular products being excluded;
• additional documentation;
• specific technical controls; or
• other contractual requirements.

These terms affect provider fit too.

A merchant technically being “accepted” does not automatically mean the offer is commercially suitable.

What Is the Difference Between Acceptance Fit and Commercial Fit?

They are separate questions.

Acceptance Fit

Can this provider support and underwrite the merchant?

Commercial Fit

Are the terms commercially appropriate?

Consider:

• processing rate;
• gateway fees;
• reserve;
• settlement;
• FX;
• chargeback fees;
• contract length;
• termination rights;
• minimum charges; and
• other fees.

Technical Fit

Can the provider actually deliver the required:

• gateway;
• API;
• ecommerce integration;
• EPOS;
• booking system;
• CRM;
• ERP;
• recurring billing;
• tokenisation;
• multi-currency processing;
• split payments; or
• other payment functionality?

MAS View

A suitable payment provider requires:

Acceptance Fit + Technical Fit + Commercial Fit.

Fail any one of those three tests and the provider may not be the right option.

Why Applying to the Cheapest Provider First Can Be a Mistake

Pricing is irrelevant if the merchant is outside the provider's acceptance criteria.

For example:

Provider A	Provider B
0.80% headline processing	1.00% headline processing
Does not support merchant's business model	Supports merchant's business model
Application declined	Application considered

Provider A does not represent a genuine 0.20% saving.

It is simply not an available acquiring route for that merchant.

Price comparison should therefore follow provider eligibility.

What Did Merchant Advice Service Research Find About Provider Fit?

The MerchantRoute Merchant Onboarding Study 2026, published by Merchant Advice Service, included 25 payments-industry respondents.

41% identified poor provider or risk fit as a contributor to merchant-account declines.

The study was an industry validation survey and should not be interpreted as measuring every UK merchant application.

However, it supports an important practical point:

provider selection can influence the application outcome before underwriting even begins.

The research also found that merchant onboarding time varied substantially according to the complexity of the merchant and application.

MAS View

Do not use merchant-account applications to discover provider appetite by trial and error.

Where possible:

establish likely fit → prepare evidence → apply.

That is more efficient than:

apply → decline → apply → decline → apply again.

Does Being Declined Mean No Provider Will Accept the Business?

No.

A decline is a decision made within a particular acquiring arrangement.

Another provider can potentially:

• have different sector appetite;
• use another acquiring relationship;
• have greater underwriting experience in the sector;
• support different countries;
• accept different transaction values;
• use different commercial controls; or
• support different technical requirements.

But businesses should establish why the first application failed before simply submitting another one.

Read our Merchant Account Declined guide.

Does “High Risk” Mean I Need a Specialist Payment Provider?

Sometimes, but not automatically.

The term “specialist provider” is also very broad.

A provider may specialise in:

• travel;
• gaming;
• financial services;
• international ecommerce;
• high transaction values;
• subscriptions;
• marketplaces;
• high-volume acquiring;
• particular countries; or
• another merchant profile.

A provider specialising in one higher-risk sector does not necessarily support all other higher-risk sectors.

MAS View

There is no meaningful provider category called simply:

“accepts high risk.”

The useful question is:

“Which specific risks does this provider have appetite for?”

Can a PSP's Risk Appetite Differ From Its Acquiring Partner?

Yes, depending on the structure.

A PSP may have its own policies while also operating within:

• acquirer requirements;
• banking-partner requirements;
• card-network rules;
• payment-method restrictions;
• geographical permissions; and
• regulatory requirements.

This is one reason provider eligibility can appear more complicated than simply reading a PSP's marketing website.

A payment provider may technically offer a product but still require individual merchant approval.

Who Sets Risk Appetite for a Payment Facilitator?

A Payment Facilitator programme operates within multiple risk layers.

These can include:

• the PayFac's own merchant policy;
• the sponsoring acquirer's policy;
• card-network requirements;
• MCC restrictions;
• transaction values;
• geography;
• fraud and chargeback exposure;
• financial exposure; and
• regulation.

Visa's published Payment Facilitator risk guidance specifically states that merchant underwriting should operate in accordance with the acquirer's underwriting policy and merchant-acceptance criteria.

Therefore, becoming or using a PayFac does not mean every merchant served by a software platform can automatically be boarded.

Read our Payment Facilitators guide.

Can Payment Method Risk Appetite Differ From Card-Acquiring Risk Appetite?

Yes.

A provider supporting a merchant for Visa and Mastercard does not automatically mean every alternative payment method offered through the same platform will support the same merchant activity.

Individual payment methods can have:

• their own prohibited categories;
• restricted products;
• country requirements;
• transaction limits;
• customer eligibility rules; and
• additional terms.

Provider selection therefore becomes more complex when the merchant needs a broad international payment-method mix.

Can Integration Requirements Affect Provider Fit Even If Risk Appetite Is Fine?

Yes.

Consider an established merchant that is completely acceptable from an underwriting perspective but requires:

• a bespoke API;
• network tokens;
• multiple MIDs;
• complex recurring billing;
• split settlements;
• booking-system integration;
• multi-acquirer routing;
• multi-currency settlement; or
• another specialist setup.

The provider may accept the risk but fail the technical requirement.

See our Integrated Payments Solutions UK guide.

What Information Helps Establish Provider Fit Before Applying?

Merchants should be able to answer:

1. What exactly does the business sell?
2. What is the Merchant Category Code?
3. Where is the business established?
4. Where are the directors based?
5. Where are customers located?
6. What is monthly card turnover?
7. What is annual card turnover?
8. What is the average transaction value?
9. What is the maximum transaction value?
10. How are products or services delivered?
11. How long after payment does fulfilment occur?
12. What is the current future-delivery exposure?
13. What do previous processing statements show?
14. What are historic refunds?
15. What are historic chargebacks?
16. Has a merchant account previously been declined or terminated?
17. What regulatory permissions or licences apply?
18. What currencies are required?
19. What payment methods are required?
20. What gateway or integrations are required?
21. Does the business need subscriptions or recurring billing?
22. Does it operate a marketplace or multi-party payment flow?
23. What settlement requirements exist?
24. What are the growth forecasts?

This creates a much more useful provider search than beginning with transaction rate alone.

The MAS Provider Risk-Appetite Test

Merchant Advice Service would consider provider fit across seven broad areas.

1. Activity Fit

Does the provider support what the merchant actually sells?

2. Risk Fit

Does the provider have appetite for the merchant's:

• MCC;
• transaction values;
• future delivery;
• chargeback profile;
• financial exposure;
• processing history; and
• business model?

3. Regulatory Fit

Where relevant, does the provider support the merchant's:

• regulated activity;
• licensing position;
• jurisdiction; and
• payment flow?

4. Geographic Fit

Can the provider support:

• business country;
• customer countries;
• currencies;
• cross-border acquiring; and
• required settlement accounts?

5. Technical Fit

Can the provider deliver the:

• gateway;
• API;
• ecommerce integration;
• recurring billing;
• EPOS;
• booking integration;
• CRM/ERP integration;
• marketplace functionality; and
• other required payment technology?

6. Operational Fit

Consider:

• settlement;
• refunds;
• chargeback handling;
• reporting;
• reconciliation;
• support;
• onboarding; and
• migration.

7. Commercial Fit

Only then compare:

• processing rates;
• gateway charges;
• scheme fees;
• FX;
• reserve;
• chargeback fees;
• minimum charges;
• contract length; and
• termination terms.

MAS View

Activity → Risk → Regulation → Geography → Technology → Operations → Commercials.

That is a more useful provider-selection sequence than:

“Who has the cheapest rate?”

What Are the Warning Signs That a Provider May Not Be the Right Fit?

Before applying, investigate further if:

• the provider cannot confirm whether it supports the sector;
• its restricted-business policy appears inconsistent with the merchant;
• the required country is unsupported;
• the merchant needs functionality the provider cannot deliver;
• the provider does not support the relevant business model;
• future-delivery requirements have not been discussed;
• high transaction values have not been disclosed;
• the actual customer-payment flow has not been explained;
• the provider cannot support the required currencies;
• the provider's reserve or settlement terms make the offer commercially unworkable; or
• the merchant is being encouraged to describe the business inaccurately simply to get through underwriting.

MAS View

If a provider only fits when the merchant's actual business activity is hidden or misclassified, it does not fit.

Should Merchants Check Provider Risk Appetite Before Applying?

Yes, particularly for more complex businesses.

A straightforward low-value UK retail merchant may have many potential acquiring routes.

The provider search becomes more important as complexity increases.

For example:

• higher-risk MCC;
• regulated sector;
• future delivery;
• large transaction values;
• high card volume;
• international customers;
• previous declines;
• terminated processing;
• subscriptions;
• marketplaces;
• custom integrations; or
• multiple countries.

The more of these factors apply, the less useful a generic “best payment provider” list becomes.

How Merchant Advice Service Uses Provider Risk Appetite

Merchant Advice Service helps businesses narrow payment-provider options according to the merchant's actual requirements.

This can include considering:

• business activity;
• Merchant Category Code;
• provider acceptance policy;
• processing volume;
• transaction values;
• business location;
• director location;
• customer geography;
• future-delivery exposure;
• processing history;
• refunds and chargebacks;
• regulatory position;
• payment flow;
• previous provider;
• previous declines or terminations;
• gateway requirements;
• platform;
• integrations;
• currencies;
• settlement;
• reserves;
• commercial pricing; and
• contract requirements.

The aim is to remove obvious mismatches before the merchant submits a formal application.

Merchant Advice Service does not make the final underwriting decision.

Provider eligibility, risk appetite and commercial terms can change.

The selected payment provider still completes its own:

• KYB;
• KYC;
• merchant underwriting;
• risk assessment;
• financial review where relevant;
• scheme screening;
• pricing; and
• contract approval.

The Payments Directory® is designed to help merchants filter providers according to business requirements and provider fit.

Merchant Advice Service is an independent payments information, comparison and provider-matching service.

MAS may receive commission or a referral fee from some payment providers where a business chooses to proceed following an introduction. This does not determine the factual information, provider-risk concepts or merchant-underwriting principles contained within this guide.

Merchant Advice Service does not make merchant-account underwriting decisions and cannot guarantee acceptance by a particular acquiring bank, PSP or payment provider.

The term “risk appetite” is used within this guide to describe provider acceptance and underwriting preferences. There is no universal merchant-risk appetite shared by every payment provider.

Payment-provider eligibility, prohibited and restricted categories, acquiring relationships, commercial policies and underwriting requirements can change.

References to Adyen and Stripe are included as examples of publicly available provider eligibility policies and should not be interpreted as recommendations, rankings or evidence that another payment provider takes the same approach.

Visa and FCA references describe the broader card-scheme and UK regulatory framework. They do not establish that a particular merchant must be accepted or declined.

Provider, FCA and card-scheme information last checked: 1 September 2026.

This guide provides general payments information and should not be treated as legal, regulatory, financial or formal compliance advice.
