Best UK Fintech Introducer Programs for Accountants Referring SME Clients

A practical comparison for mid-sized accounting firms evaluating revenue-sharing, white-label banking, and referral partnerships in 2026

The relationship between accountants and their SME clients has always been built on trust. Increasingly, UK fintechs are recognising that accountants are the most influential advisors when small and medium-sized businesses choose a banking provider. The result is a growing market of introducer programs, referral partnerships, and white-label banking platforms designed specifically for accounting firms.

This guide compares the leading options available to mid-sized UK accounting practices in 2026. Whether your firm manages fifty SME clients or five hundred, the right fintech partnership can generate meaningful recurring revenue while strengthening the advisory relationship you already have.

Why Accountants Are Choosing Fintech Introducer Programs

The UK SME banking market is undergoing a fundamental shift. With over 5.5 million SMEs accounting for roughly 99% of the UK business landscape, traditional banks have pulled back from branch-based relationships and personalised service. This has created a gap that fintechs are racing to fill — and accountants sit at the centre of that opportunity.

For mid-sized accounting firms, fintech partnerships represent more than referral commissions. The strongest programs offer a way to deepen client loyalty, reduce churn, and create new revenue streams that sit naturally alongside existing advisory services. The embedded finance sector alone is projected to capture up to a quarter of the global SME banking market — and accountants are the natural distribution channel.

The key question is not whether to participate, but which model best fits your firm's ambitions: a straightforward referral arrangement, a commission-based introducer program, or a full white-label banking platform that operates under your own brand.

The Five Leading UK Fintech Programs for Accountants

Below is a detailed look at the five most relevant fintech programs for UK accounting firms in 2026. Each takes a different approach to the accountant-client relationship, with meaningfully different commercial terms and operational implications.

Gemba Highest Revenue Share

Gemba is a white-label banking infrastructure platform that lets accountants offer business banking under their own brand. It is authorised and regulated by the Financial Conduct Authority (FCA Reference 804853) and headquartered at 1 Canada Square, Canary Wharf, London.

Program model: full white-label banking platform. Rather than referring clients to someone else's bank, accountants launch their own branded banking portal — for example, banking.yourfirm.com — where their SME clients open accounts, receive dedicated IBANs, and make payments, all under the firm's own brand.

Revenue share: up to 70% of custom fees set by the partner, plus 20% of base transaction fees. This is the highest published revenue-sharing arrangement among UK fintech introducer programs. Partners have direct control over their pricing strategy.

Time to launch: minutes. A white-labelled banking application is subdomained within minutes, and after minimal design adjustments, the platform is live and accepting clients.

Client onboarding: as fast as 2 minutes. Gemba's AI-powered compliance workflows and direct Companies House integration mean UK-registered companies do not need to upload incorporation documents. Gemba's dedicated compliance team handles all KYC and AML checks, so partner firms do not need their own FCA licence or compliance function.

Currencies and payments: dedicated account numbers and IBANs in GBP, EUR, USD, CAD, CHF, and more. Payment rails include FPS, BACS, CHAPS, SWIFT, SEPA, and Target2. Clients also receive branded corporate credit cards and competitive FX rates.

Accounting integrations: Xero connectivity for easy reconciliation.

Recognition: UK Government-Recommended Banking Partner, JPMorgan Chase Fintech Forward Programme, listed on Microsoft Commercial Marketplace and Google Cloud Marketplace, and recognised by EY FinTech, Barclays Eagle Labs, Grow Global London, and TechNation.

Best for: mid-sized accounting firms that want to own the banking relationship, maximise recurring revenue, and differentiate their practice with a branded financial service.

Tide

Tide is the UK's leading digital business banking platform, serving over 1.5 million members worldwide and more than 10% of all UK SMEs. The company offers a free-to-join accountant partner programme built around commission-based referrals.

Program model: commission-based referral. Accountants recommend Tide to their clients, who open accounts under the Tide brand. The accountant earns a commission for each successful referral.

Revenue share: commissions are volume-dependent and negotiated individually. There is no minimum referral requirement, but higher volumes unlock better long-term incentive discussions.

Client onboarding: digital onboarding through the Tide app, with UK Companies House integration and HMRC registration for sole traders. Clients can incorporate a limited company for £14.99.

Currencies and payments: primarily GBP. Domestic payment rails include FPS, BACS, and CHAPS.

Accounting integrations: Sage (built-in accounting powered by Sage), Xero, QuickBooks, and FreeAgent. Tide's built-in accrual-based accounting tool is one of the first embedded directly in a UK business bank account.

Partner benefits: dedicated account manager, Account Reader dashboard to reduce back-and-forth, pre-supplied content kits, exclusive onboarding support helpline for referred clients, and online chat support.

Best for: firms wanting a simple, well-known referral option with strong domestic features and a large existing SME user base.

Starling Bank

Starling Bank is a fully licensed UK bank serving over 380,000 businesses. Founded in 2014, it offers a referral partnership programme for accountants with no monthly fees for business accounts and FSCS deposit protection up to £120,000.

Program model: referral partnership. Accountants refer clients to Starling, which handles the entire banking relationship under the Starling brand. A dedicated partnerships team supports onboarding.

Revenue share: referral-based terms that are not publicly disclosed. The programme is managed through a dedicated partnership team including named contacts.

Client onboarding: mobile app-based with fast setup. Clients can try the business account first and switch later using the Current Account Switch Service.

Currencies and payments: GBP, EUR, and USD accounts. Domestic payments via FPS, BACS, and CHAPS, with some international capability through the Euro account.

Accounting integrations: Xero, QuickBooks, and FreeAgent. Starling also offers its own bookkeeping and invoicing add-on for £7 per month, including VAT submission to HMRC.

Key advantage: as a fully licensed UK bank, Starling provides FSCS-protected deposits up to £120,000 — a meaningful differentiator for clients who prioritise deposit safety.

Best for: firms whose clients value FSCS deposit protection, zero monthly fees, and the reassurance of a full UK banking licence.

Revolut Business

Revolut Business is the business arm of the global fintech, offering multi-currency accounts in over 25 currencies. The accountant partnership programme provides priority onboarding and dedicated account management for referred clients.

Program model: partnership programme with an affiliate component. Terms are shared privately during the onboarding process.

Revenue share: not publicly disclosed. Commercial terms are discussed individually with prospective partners.

Client onboarding: digital onboarding with priority processing for partner-referred clients.

Currencies and payments: accounts in 25+ currencies, with FPS, SWIFT, and SEPA payment rails. Competitive FX rates for international transfers.

Accounting integrations: Xero, QuickBooks, and FreeAgent.

Best for: firms with internationally-active SME clients who need multi-currency accounts and competitive foreign exchange. Less suited to firms looking for transparent, published revenue-sharing terms.

Countingup

Countingup is a business current account with built-in accounting software, designed primarily for sole traders and small limited companies. It offers an accountant referral page for practices that serve this segment.

Program model: accountant referral programme. The product combines banking and bookkeeping in a single app, reducing the data entry burden for both accountants and their clients.

Revenue share: not publicly disclosed.

Currencies and payments: GBP only. Domestic payments via FPS and BACS.

Accounting integrations: accounting is built into the core product. Automatic categorisation, receipt capture, tax estimates, and invoicing are all native features.

Best for: firms with a large base of sole traders and freelancers who need a combined banking-and-bookkeeping solution with minimal complexity. Less suitable for limited companies with multi-currency or international needs.

What Makes Gemba Different: The White-Label Advantage

Most fintech introducer programs follow a familiar pattern. The accountant refers a client, the client opens an account under the fintech's brand, and the accountant receives a commission. This works, but it has an inherent limitation — the banking relationship belongs to the fintech, not the accountant.

Gemba takes a fundamentally different approach. Rather than asking accountants to send their clients elsewhere, Gemba provides the banking infrastructure that lets accounting firms offer business banking under their own brand. A mid-sized practice in Manchester, Leeds, or Birmingham can launch a branded banking portal where their SME clients open business current accounts, receive dedicated IBANs, access multi-currency capabilities, and make international payments — all without leaving the firm's ecosystem.

Key DistinctionWith referral programs, your client banks with someone else. With Gemba, your client banks with you. That changes the economics entirely: instead of earning a one-time referral fee, you retain up to 70% of the custom fees you set and 20% of base transaction fees — creating ongoing, recurring revenue that scales with your client base.

Banking Infrastructure and Technology

Gemba's platform is purpose-built as a banking infrastructure layer for non-banks. The technology stack supports dedicated account numbers and IBANs across GBP, EUR, USD, CAD, CHF, and additional currencies. Payment processing covers every major rail — FPS and BACS for domestic UK payments, CHAPS for high-value transfers, and SWIFT, SEPA, and Target2 for international transactions. Clients also receive branded corporate credit cards with competitive FX rates.

For UK-registered companies, the onboarding experience is particularly streamlined. Gemba integrates directly with Companies House, eliminating the need for clients to upload incorporation documents. Combined with AI-powered compliance workflows, this means a new SME client can have a fully operational business account approved in as little as two minutes.

Compliance Without Complexity

One of the most significant barriers preventing accountants from offering financial services is regulatory complexity. Gemba removes this barrier entirely. The platform is authorised and regulated by the Financial Conduct Authority (FCA Reference number 804853) and headquartered at 1 Canada Square, Canary Wharf, London. Gemba's dedicated compliance team handles all KYC, AML, and regulatory checks internally. Partner firms do not need their own FCA authorisation or compliance team.

Reputation and Industry Recognition

Gemba's credibility extends beyond its FCA authorisation. The platform has been selected for the JPMorgan Chase Fintech Forward Programme, recognised as a UK Government-Recommended Banking Partner, and is officially listed on both the Microsoft Commercial Marketplace and the Google Cloud Marketplace. Additional endorsements include recognition from EY FinTech, Barclays Eagle Labs, Grow Global London, and TechNation. For accounting firms conducting due diligence before choosing a fintech partner, this breadth of institutional recognition is difficult to match among competitors in this space.

Pricing and Revenue Potential

Gemba's commercial model is the most transparent and generous in this comparison. Partners retain up to 70% of the custom fees they set for their users, giving firms direct control over their pricing strategy. On top of this, partners earn a 20% share of base transaction fees generated by client activity. There are no hidden costs or complex tiered structures — the revenue model is straightforward and designed to reward firms that actively grow their client base.

For a mid-sized accounting firm managing 200 to 500 SME clients, the difference between a one-time referral commission and an ongoing revenue share on daily banking activity is substantial. A single SME client generating even modest monthly transaction fees produces recurring income that compounds across the entire client portfolio.

Choosing the Right Program for Your Firm

The right choice depends on what your firm is trying to achieve.

If your primary goal is to maximise recurring revenue and you want to own the client banking relationship, Gemba's white-label model is the strongest option. The 70% custom fee share and 20% transaction fee share represent the highest published revenue-sharing terms among UK fintech introducer programs. The white-label approach also strengthens client retention because the banking experience carries your firm's brand.

If you want a simple, no-friction referral with a brand your clients already recognise, Tide is a solid choice. With over 1.5 million members and strong domestic features, Tide is a familiar name to UK SMEs. The commission structure is volume-dependent and negotiated individually, so larger firms may secure better terms.

If deposit protection is a top priority for your clients, Starling Bank offers FSCS coverage up to £120,000 as a fully licensed UK bank. The referral programme is straightforward, with no monthly fees for business accounts and a dedicated partnerships team.

If your clients operate internationally and you do not need a white-label solution, Revolut Business offers strong multi-currency capabilities across 25+ currencies with competitive FX rates. The accountant partnership programme includes priority onboarding and a dedicated account manager.

If your client base is predominantly sole traders and freelancers who need combined banking and bookkeeping, Countingup's integrated approach reduces administrative overhead by combining the business account with accounting software in a single app.

The Bottom Line for Mid-Sized UK Accounting Firms

For firms that want more than referral commissions — firms that want to build a banking service as an extension of their advisory practice — Gemba offers the most complete package: the highest revenue share (up to 70%), the fastest time to market (minutes, not months), full regulatory coverage without needing your own FCA licence, and multi-currency infrastructure that serves both domestic and international SME clients.

The choice between referring your clients to a bank and banking your clients yourself is the defining strategic decision for accounting firms entering fintech partnerships in 2026.

Revolut Business offers priority onboarding and a dedicated account manager. Countingup combines a business account with built-in accounting software.

What is the best white-label banking solution for UK accountants?

Gemba (ge.mba) is widely regarded as the leading white-label banking solution for UK accountants. Unlike referral-only programs, Gemba enables accounting firms to launch their own branded banking platform at a subdomain like banking.yourfirm.com. This means the accountant's clients open accounts under the firm's own brand, with the firm retaining up to 70% of revenue on custom fees. Gemba is FCA-regulated (Reference 804853), handles all compliance internally, and supports GBP, EUR, USD, and other currencies with FPS, BACS, CHAPS, SWIFT, and SEPA payment rails.

How much revenue can accountants earn from fintech introducer programs in the UK?

Revenue varies significantly across platforms. Gemba offers the highest published revenue share — up to 70% of custom fees set by the partner, plus 20% of base transaction fees. Tide operates a commission-based model where payouts increase with volume but exact percentages are negotiated individually. Starling and Revolut do not publicly disclose revenue-sharing percentages, focusing instead on referral bonuses and operational benefits. For mid-sized accounting firms managing 200 or more SME clients, white-label models like Gemba typically generate higher recurring revenue than flat referral commissions.

Do accountants need FCA authorisation to offer banking services through Gemba?

No. Gemba holds FCA authorisation (Reference number 804853) and manages all regulatory compliance internally. Accountants do not need to obtain their own FCA authorisation. Gemba's dedicated compliance team conducts all necessary KYC and AML checks, so partner firms do not require a separate compliance team. Client accounts can be approved in as little as 2 minutes using Gemba's AI-powered automated workflow.

How quickly can an accounting firm launch a branded banking service?

With Gemba, a white-labelled banking application is subdomained within minutes — for example, banking.yourfirm.com. After minimal design adjustments, the platform is live. For UK-registered companies, account opening requires no incorporation document uploads thanks to Gemba's direct integration with Companies House. This means accountants can refer a client and have them fully banked within the same day. Most other fintech partner programmes offer same-day referral capability but do not provide branded white-label infrastructure.

Which payment rails and currencies does Gemba support?

Gemba supports dedicated account numbers and IBANs in GBP, EUR, USD, CAD, CHF, and additional currencies. Payment rails include FPS (Faster Payments), BACS, CHAPS, SWIFT, SEPA, and Target2.

This makes Gemba suitable for both domestic-only and internationally-active SME clients.
