Alternative Payment Processors to Stripe

A Payments Strategy Guide for High-Volume UK Businesses

Stripe is one of the most capable payment platforms in the market. For many businesses, it is exactly the right place to start — and it can continue to support companies at significant scale.

But the payment setup that worked when your business was processing £1 million a year may not necessarily be the right commercial structure when you are processing £10 million, £50 million or more.

At that point, the question is rarely simply:

“What is the best alternative to Stripe?”

A better question is:

“Is our current payment setup still the best fit for the size, complexity and direction of our business?”

For established businesses processing significant card volumes, a payments review may uncover opportunities to:

• renegotiate processing costs;

• move from standard or blended pricing to a different commercial structure;

• improve authorisation performance;

• introduce additional acquirers or payment routes;

• support new countries and currencies;

• solve integration limitations;

• migrate recurring payments;

• introduce alternative payment methods;

• reduce reliance on a single provider; or

• in some platform businesses, turn payments into an additional revenue stream.

Changing provider isn't always the answer. Sometimes renegotiating or restructuring your existing Stripe arrangement makes more sense.

The important thing is knowing the difference.

Quick Summary

If your business is processing £750,000+ per month through Stripe, it may be worth reviewing whether your current payment setup still represents the best commercial and operational fit.

That does not automatically mean switching away from Stripe. High-volume businesses may be able to renegotiate pricing, move to a different pricing structure or retain Stripe as part of a broader multi-provider setup.

A review becomes particularly valuable if you are:

• processing significantly more than when your original pricing was agreed;
• expanding into the UK or Europe;
• struggling with specific integrations;
• operating subscriptions or recurring payments;
• considering multiple acquirers;
• looking to reduce processing costs;
• approaching a contract or commercial review; or
• operating a SaaS or platform business that could potentially turn payments into an additional revenue stream.

For larger merchants, the question is rarely simply “What is the best Stripe alternative?”

It is:

“What payment structure is now right for our business?”

Merchant Advice Service works with established businesses to assess their current setup, understand their technical and commercial requirements and identify suitable payment-provider options.

MAS does not charge merchants for this service.

Is Stripe expensive for a high-volume business?

Not necessarily.

One of the biggest mistakes businesses make when reviewing Stripe is comparing their current pricing with the publicly advertised standard rate and assuming that represents Stripe's enterprise proposition.

It doesn't.

As of August 2026, Stripe's published UK standard pricing includes 1.5% + 20p for standard UK cards and 2.5% + 20p for EU cards. Stripe also publicly offers custom pricing for businesses with large payment volumes or more complex requirements, including:

• volume discounts;

• interchange-plus pricing;

• country-specific rates;

• multi-product discounts; and

• customised enterprise packages.

So if your business has grown substantially while remaining on a pricing structure agreed several years ago, the first question shouldn't necessarily be:

“Who can replace Stripe?”

It should be:

“Are we still on the right commercial arrangement?”

At high processing volumes, relatively small pricing differences become material.

That is why processing costs should be assessed against your actual payment profile rather than a headline percentage alone.

When should a business review its Stripe setup?

There isn't a single turnover point where a business suddenly “outgrows” Stripe.

For most larger merchants, the trigger is a change in the business rather than a particular number.

A review becomes worthwhile when one or more of the following applies.

Your card volume has increased significantly

Growth changes your negotiating position.

If your business negotiated its payment arrangement when volumes were materially lower, it may be worth benchmarking your current commercial terms against what is available to a business of your current size.

For established merchants processing £750,000+ per month, seemingly small differences in acquiring, gateway, cross-border and ancillary fees can become significant over a year.

You are approaching a contract or commercial review

A renewal is an obvious point to benchmark the market.

But businesses don't necessarily need to wait for renewal to understand whether their current arrangement remains competitive.

Knowing what alternative commercial structures are available gives your business considerably more information when negotiating with an incumbent provider.

Your integration requirements have become more complicated

Perhaps Stripe was originally connected to a straightforward ecommerce checkout.

The business may now require:

• Shopify;

• custom APIs;

• booking or reservation systems;

• subscription platforms;

• marketplace payments;

• multiple sales channels;

• multiple merchant accounts;

• complex reconciliation;

• tokenisation;

• international acquiring; or

• multiple payment providers.

At this point, payment provider selection becomes as much a technology and operational decision as a pricing decision.

You are expanding into Europe

A business accepting predominantly UK cards can have a very different payment profile after expanding internationally.

Questions may include:

• Should payments continue to be acquired in the UK?

• Would local acquiring improve the setup?

• Which currencies should be supported?

• Which local payment methods matter?

• What are the cross-border costs?

• Could authorisation rates differ between markets?

• Is one payment provider sufficient across every territory?

Stripe supports international payments, multiple currencies and a broad range of payment methods, so expansion alone isn't a reason to leave.

But international growth is a very good reason to review the architecture around your payments.

You have recurring payments or subscriptions

Recurring payments make switching considerably more sensitive.

A business may have thousands -  or hundreds of thousands - of customer payment credentials associated with its existing processor.

That can create the impression that switching providers is impossible.

It usually isn't.

Stripe confirms that its migration service can support exports of stored card and certain other payment-method data to another payment provider, with sensitive payment information transferred securely under the relevant PCI requirements.

However, payment credentials are only part of the picture.

Subscriptions, billing logic, retries, customer communications, reconciliation and internal systems all need to be considered.

This means the question isn't simply:

“Can we move our Stripe tokens?”

It is:

“How do we change payment infrastructure without disrupting our recurring revenue?”

That requires considerably more planning.

Before selecting a Stripe alternative, it can be useful to review the wider commercial and technical requirements of your business. Our Payments Strategy Library brings together guidance for established merchants considering a provider change.

Should we ask Stripe for better pricing before switching?

In many cases, yes.

A payment-provider review doesn't have to result in a provider change.

If Stripe continues to satisfy your operational, technical and geographic requirements, renegotiating your existing arrangement may be the best outcome.

Stripe openly states that custom packages can include volume discounts and interchange-plus pricing for businesses with larger payment volumes.

Before entering any pricing conversation, however, a business should understand its own transaction data.

Useful information includes:

• annual and monthly processing volume;

• transaction count;

• average transaction value;

• debit versus credit-card mix;

• consumer versus commercial cards;

• UK, EEA and international card mix;

• refunds;

• chargebacks;

• currencies;

• payment methods;

• current authorisation rate;

• cross-border processing;

• subscription volume; and

• other Stripe products being used.

Without this information, comparing one headline percentage with another can be misleading.

Blended pricing vs interchange-plus: what should larger merchants consider?

This is another area where scale matters.

Simple blended pricing is attractive because it is predictable and easy to understand.

You pay an agreed amount for a transaction without having to analyse all of the individual components sitting underneath it.

For larger businesses, however, interchange-plus — often abbreviated to IC+ — can provide greater visibility into the underlying cost of card acceptance.

Broadly, card-processing costs can include:

Interchange
A fee associated with the card transaction.

Scheme fees
Charges associated with the card network.

Acquirer or processor margin
The commercial margin charged for providing the acquiring/processing service.

There can also be additional charges relating to gateway services, international cards, currencies, fraud tools, disputes, tokenisation, alternative payment methods and other services.

Neither blended nor IC+ pricing is automatically cheaper.

The correct structure depends on the merchant's card mix, transaction profile and negotiated terms.

But once card volumes become substantial, understanding what sits beneath the headline processing rate becomes increasingly important.

Can switching from Stripe reduce processing fees?

Potentially — but cost alone should rarely determine an enterprise payment strategy.

A cheaper provider that creates problems elsewhere may ultimately be more expensive.

A proper comparison should consider:

This is why asking for “a cheaper Stripe alternative” can lead to the wrong decision.

The objective should be to find the best overall payment structure, not simply the lowest advertised rate.

Find Your New Processor

Should a high-volume business use more than one payment provider?

Increasingly, larger merchants consider this question.

Stripe itself now publishes guidance on processor-agnostic payment architectures, where businesses can work with multiple processors rather than tying every element of checkout, billing and back-office infrastructure to a single provider.

Potential benefits can include:

• reducing dependency on one processor;

• routing transactions differently;

• supporting regional requirements;

• accessing different payment methods;

• creating resilience;

• improving negotiating leverage; and

• optimising for cost or payment performance.

Stripe notes that processor-agnostic approaches can allow domestic transactions to use local acquirers while international transactions are routed differently.

That doesn't mean every £10m merchant needs a sophisticated orchestration layer.

Complexity has a cost too.

The decision should depend on transaction volume, international footprint, business criticality and the benefit additional payment routes would genuinely create.

What if Stripe is technically embedded into our business?

This is common.

For a rapidly growing company, Stripe may have started as “the payment provider” and gradually become intertwined with:

• checkout;

• subscriptions;

• customer accounts;

• invoicing;

• refunds;

• reporting;

• fraud tools;

• revenue recognition;

• marketplace payments; and

• internal workflows.

That creates switching complexity — but not necessarily provider lock-in.

Stripe provides mechanisms for exporting certain stored payment data to another payment provider.

The larger strategic question is what else would need to change.

Before considering migration, map:

1. What Stripe products are being used?

2. Which systems depend on Stripe data?

3. Where are payment credentials stored?

4. How are subscriptions managed?

5. What webhooks and API calls exist?

6. How are refunds and disputes handled?

7. How does finance reconcile settlements?

8. Which internal teams rely on Stripe?

Only then should alternative architectures be considered.

Have you outgrown Stripe, or simply outgrown your current payment strategy?

This distinction matters.

Stripe supports some of the world's largest businesses and has an enterprise proposition specifically designed for larger payment volumes and complex requirements.

So growth alone does not mean you need to leave Stripe.

But growth does mean you should periodically question whether the structure you originally selected still represents the best commercial and operational fit.

For an established business, there are broadly four possible outcomes from a payment review.

1. Keep Stripe exactly as it is

If the pricing, performance and functionality remain competitive, changing for the sake of changing makes no sense.

2. Keep Stripe but renegotiate

Your volume or profile may now justify different commercial terms.

3. Keep Stripe as part of a wider payment setup

Some businesses benefit from adding another acquiring or processing relationship rather than replacing the incumbent completely.

4. Move some or all payment processing elsewhere

If another structure offers a materially better combination of pricing, integration, geographic support or strategic fit, a managed migration may make sense.

The right answer is different for every business.

Stripe alternatives for high-volume merchants

There is no universal “best alternative to Stripe”.

For a business processing £10m+ annually, the provider shortlist should be created after the requirements have been mapped, not before.

Two businesses processing exactly the same volume can require entirely different payment setups.

For example:

Business A

• UK ecommerce;

• £12m card volume;

• mostly consumer debit cards;

• Shopify;

• one-off purchases;

• almost entirely domestic.

Business B

• £12m card volume;

• subscription model;

• custom API;

• UK and six EU markets;

• multiple currencies;

• significant international card mix.

Their annual volume is identical.

Their optimal payment strategy may be completely different.

This is why Merchant Advice Service does not simply publish a league table and tell every high-volume business to use the same provider.

Could your payment setup become a revenue stream?

For some businesses, the opportunity goes beyond reducing processing costs.

If you operate:

• a SaaS platform;

• booking technology;

• hospitality software;

• a membership platform;

• a marketplace;

• vertical software; or

• another platform with an established customer portfolio,

you may be able to integrate payments into your proposition and participate commercially in the processing revenue generated by your customer base.

Rather than treating payments purely as a business cost, your company may be able to negotiate a commercial buy rate with a payment partner and build a margin into the payment proposition offered to customers.

This isn't appropriate for every business and needs to be structured correctly.

But for platforms with an established customer base, payments can potentially become an entirely new revenue line.

If you are already reviewing Stripe, this is worth considering before simply negotiating another processing rate.

Before changing Stripe: 10 questions for your leadership team

Before approaching another provider, we recommend answering these questions:

1. How much are we actually processing each month?

2. What is our true effective payment cost?

3. Which elements of the current setup are causing problems?

4. Which integrations are non-negotiable?

5. Do we expect our geographic footprint to change?

6. Do we need recurring billing or stored payment credentials?

7. Would multiple acquirers create genuine value?

8. Could a different payment structure improve commercial performance?

9. Could payments become a revenue stream rather than simply a cost?

10. What does our business need its payment infrastructure to look like in three years?

Those answers are considerably more useful than beginning with a list of payment providers.

Request a Payments Strategy Review

If your business is processing £750,000+ per month and you are considering changing Stripe, renegotiating your current payment setup or reviewing whether your payment infrastructure still fits the business, Merchant Advice Service can help.

We work through your requirements first, including:

• current processing volume;

• existing payment providers;

• pricing structure;

• card and geographic mix;

• integration requirements;

• subscriptions;

• international expansion;

• settlement;

• payment methods;

• future growth plans; and

• opportunities to monetise payments across an existing customer portfolio.

We can then identify suitable payment-provider options based on the requirements of the business.

The commercial relationship remains directly between your business and the selected payment provider. Merchant Advice Service remains available if you need support or advice before, during or after the introduction.

Merchant Advice Service does not charge merchants for this service.

If you proceed with a payment provider introduced by us, we receive commission from the provider. We do not recommend providers on the basis of which pays the highest commission; the objective is to identify the solution that best fits your requirements.
