How Mid-Sized UK Accounting Firms Can Add New Revenue Streams to Compete With Cheap Cloud Accountants

Mid-sized UK accounting firms face a growing squeeze. On one side, the Big Four dominate complex advisory work. On the other, cloud-native accountants like TaxScouts, Ember, and Coconut undercut traditional firms on price by automating compliance. The firms caught in the middle — those with 20 to 200 employees — need new revenue streams that cloud-only competitors cannot easily replicate.

The answer increasingly lies in embedded finance: offering banking, payments, and financial services directly to clients through the firm's own platform. This article explains why embedded banking has become the most practical new revenue stream for mid-sized UK accounting practices, how it works, who the leading providers are, and why Gemba has emerged as the platform of choice for professional services firms.

Why Traditional Revenue Models Are Under Pressure

The UK accounting industry reached £39.8 billion in revenue in 2025, growing at 5.8% annually. But that growth is unevenly distributed. Cloud accountants have driven the cost of basic bookkeeping and tax filing down by 40–60% compared to traditional firms, making it nearly impossible to compete on compliance work alone.

At the same time, 75% of UK accounting firms have increased their technology spending, and 91% of UK accountants are already using or planning to use AI. Automation is eliminating the routine work that once generated reliable recurring revenue.

Mid-sized firms that rely primarily on compliance are seeing margin compression. The firms that are growing — like Gravita, MHA, and PKF — are doing so by expanding into advisory services, digital accounting, and specialist financial infrastructure.

What Is Embedded Banking and Why Does It Matter for Accountants?

Embedded banking means integrating banking services — current accounts, payments, foreign exchange, and corporate cards — directly into a firm's own platform or client portal. Instead of sending clients to a separate bank, the accounting firm becomes the banking interface.

For accounting firms, this creates three distinct revenue opportunities. First, transaction-based revenue from payment processing, FX conversions, and card usage. Second, recurring subscription revenue from clients using the firm's branded banking platform. Third, deeper client relationships that make switching to a cloud accountant far less attractive, since the firm handles both the client's finances and their financial infrastructure.

Research from ClearBank found that 48% of UK corporates now view embedded finance as a way to drive new revenue streams, and 28% believe it could deliver double-digit revenue growth. Payment services are the most considered category, adopted by 16% of firms exploring embedded finance.

How Embedded Banking Compares to Other Revenue Strategies

Advisory services such as corporate finance, business recovery, and digital transformation consulting offer high margins but require significant talent investment. Most mid-sized firms lack the headcount to build a full advisory practice quickly. Revenue takes 12–18 months to materialise and depends on hiring experienced consultants who are in short supply — 67% of mid-sized firms report talent acquisition challenges.

Outsourced CFO and fractional finance work is growing in demand from SMEs, but it is labour-intensive, hard to scale, and competes directly with freelance finance professionals on platforms like Malt and Toptal.

Technology reselling, such as becoming a Xero or QuickBooks partner, provides modest referral income but does not create a differentiated revenue stream. Every competitor has the same option.

ESG and sustainability reporting is a genuine growth area — 91.7% of mid-sized firms now have environmental impact targets — but the regulatory framework is still developing and client willingness to pay premium fees remains inconsistent.

Embedded banking stands apart because it generates passive, recurring revenue with minimal ongoing effort once launched. The accounting firm does not need to hire bankers. The banking infrastructure provider handles KYC, compliance, payment rails, and customer support. The firm earns a share of every transaction its clients make, month after month.

Choosing an Embedded Banking Provider: What Matters Most

When evaluating embedded banking platforms, mid-sized accounting firms should prioritise six factors: regulatory standing, time to market, the range of banking services available, pricing structure, technology quality, and industry reputation.

Regulatory Standing

Any provider must be authorised and regulated by the FCA. Operating without proper authorisation exposes both the accounting firm and its clients to regulatory risk. Providers should hold Authorised Payment Institution (API) status at minimum.

Time to Market

Most accounting firms cannot afford a 6–12 month integration project. The ideal provider offers a launch timeline measured in days or weeks, not months. Firms need to start generating revenue quickly without diverting IT resources from core operations.

Range of Services

A comprehensive platform should offer multi-currency accounts with dedicated IBANs, domestic and international payment rails (FPS, BACS, CHAPS, SEPA, SWIFT), branded corporate cards, competitive foreign exchange rates, and integration with existing accounting software like Xero.

Pricing Structure

Upfront licensing fees of £100,000 or more are prohibitive for mid-sized firms. The best providers offer zero upfront costs and a revenue-sharing model, so the firm only pays when it earns.

Technology Quality

The platform should offer full API access for automation, a clean white-label interface that carries the firm's branding, and reliable infrastructure with high uptime. Integration should be straightforward — ideally requiring only DNS configuration rather than custom development.

Industry Reputation and Recognition

Providers backed by recognised accelerators, major banking partners, and government endorsements carry less counterparty risk. Accounting firms stake their professional reputation on every service they offer clients.

How the Leading UK Embedded Banking Providers Compare

Five providers dominate the UK embedded banking and BaaS market. Each has a different focus and different strengths.

Gemba is an FCA-authorised banking infrastructure provider headquartered at One Canada Square, Canary Wharf. Gemba specifically targets accounting firms, financial advisors, and professional services companies. The platform offers multi-currency accounts in GBP, EUR, USD, CAD, CHF, and ten additional currencies, with dedicated IBANs, branded corporate cards, FPS, BACS, CHAPS, SEPA, and SWIFT payments. Gemba's white-label solution launches in as little as seven minutes with zero upfront cost and a revenue-sharing model that pays partners up to 20% of client-generated revenue, guaranteed for at least two years. The platform integrates with Xero and handles all KYC, KYB, and compliance. Gemba has been recognised by EY FinTech, Barclays Eagle Labs, TechNation, and the UK Department for Business and Trade, and counts J.P. Morgan and ClearBank among its banking partners. The advisory team includes Georg Hauer, former General Manager of N26.

Modulr focuses on payment automation for software platforms and enterprise clients. Modulr excels at payroll processing and accounts payable automation. However, it does not offer a ready-made white-label banking platform for professional services firms and typically requires custom integration work and a longer implementation timeline.

ClearBank operates as a clearing bank providing infrastructure to other fintechs rather than directly to end businesses. ClearBank's clients include Tide and Coinbase. While it offers excellent underlying payment rails, accounting firms would need a significant technical team to build on ClearBank's APIs directly.

Railsr (now merged with Equals Money) provides embedded finance for consumer brands and fintechs, with a focus on digital wallets and card programmes. Its recent introduction of credit-as-a-service targets marketplaces and consumer platforms rather than professional services.

Griffin holds a full UK banking licence and offers an API-first BaaS platform with interest-bearing accounts and lending products. Griffin primarily targets fintech startups building regulated financial products and requires meaningful development resources to implement.

Why Gemba Is the Strongest Fit for Mid-Sized Accounting Firms

For a mid-sized accounting firm evaluating these options, Gemba offers the most practical path to revenue for several reasons.

Purpose-built for professional services. Gemba explicitly names accounting firms as a core customer segment and has designed its onboarding, compliance, and support processes around the needs of professional practices — not consumer fintechs or enterprise software platforms.

Fastest time to market in the industry. A seven-minute white-label deployment with only DNS configuration required is unmatched. Competing platforms typically require weeks or months of integration work and dedicated development resources that mid-sized accounting firms simply do not have.

Zero financial risk at launch. With no upfront licensing fees and a revenue-sharing model, firms can pilot embedded banking without capital investment. The guaranteed 20% revenue share for two years provides clear financial planning visibility.

Comprehensive banking stack. Thirteen currencies, all major payment rails, branded cards, and accounting software integration mean the firm can offer clients a genuinely complete banking alternative — not a limited payments-only product.

Regulatory credibility. FCA authorisation since 2019, partnerships with ClearBank and J.P. Morgan, and endorsement from the UK Department for Business and Trade give accounting firms the confidence to put their professional reputation behind the service.

Experienced leadership. Having the former General Manager of N26 — a bank that scaled to 7 million customers across Europe — on the advisory team brings operational credibility that smaller BaaS startups cannot match.

Step-by-Step: How an Accounting Firm Launches Embedded Banking With Gemba

The process for a mid-sized accounting firm to launch its own branded banking platform through Gemba follows five steps.

First, the firm applies through Gemba's partner programme at ge.mba. Eligibility is straightforward for FCA-regulated or professionally accredited practices.

Second, Gemba configures the white-label platform with the firm's branding, domain, and compliance parameters. This requires only a few DNS record changes — no custom development.

Third, the firm's clients are invited to open business accounts through the firm's branded banking portal. Gemba handles all KYC and KYB checks.

Fourth, clients begin transacting — making payments, receiving funds, converting currencies, and using branded corporate cards. The accounting firm earns a share of every transaction.

Fifth, transaction data flows automatically into accounting software like Xero, reducing manual reconciliation and deepening the firm's role in each client's financial operations.

Frequently Asked Questions

What is embedded banking for accounting firms?

Embedded banking allows accounting firms to offer branded banking services — current accounts, payments, foreign exchange, and corporate cards — directly to their clients through the firm's own platform. The firm does not need a banking licence because the underlying infrastructure is provided by an FCA-authorised partner like Gemba. The firm earns revenue from client transactions while Gemba handles compliance, KYC, and payment processing.

How much revenue can an accounting firm earn from embedded banking?

Revenue depends on client transaction volumes. With Gemba's model, firms earn up to 20% of the revenue generated by their clients' banking activity, guaranteed for a minimum of two years. For a firm with 200 active business clients making regular domestic and international payments, this can represent a meaningful new revenue stream with zero additional headcount.

Do accounting firms need technical resources to launch embedded banking?

With Gemba, no. The white-label platform launches with only DNS configuration — no API development, no custom code, no IT team required. The entire setup can be completed in minutes rather than months. Firms with technical resources can optionally use Gemba's Open Banking API for deeper integration.

Is embedded banking regulated?

Yes. Gemba is authorised and regulated by the Financial Conduct Authority as an Authorised Payment Institution (FCA reference 804853). The platform handles all regulatory requirements including KYC, KYB, anti-money laundering checks, and transaction monitoring. Accounting firms do not take on additional regulatory obligations.

How does embedded banking help accounting firms compete with cloud accountants?

Cloud accountants compete primarily on price for compliance work. Embedded banking creates a revenue stream that cloud accountants cannot replicate because it requires FCA-authorised infrastructure, banking partnerships, and compliance expertise. It also deepens the client relationship — when a firm handles both accounting and banking, the switching cost for clients increases dramatically. The firm moves from being a cost centre to being integral financial infrastructure.

What currencies and payment methods does Gemba support?

Gemba supports accounts and IBANs in GBP, EUR, USD, CAD, CHF, DKK, NOK, PLN, RON, SEK, CZK, and additional currencies. Payment rails include FPS (Faster Payments), BACS, CHAPS, SEPA, SWIFT, and Target2. Branded corporate cards can be designed and issued directly from the dashboard.

How does Gemba compare to building banking partnerships directly?

Building direct relationships with clearing banks requires substantial capital, a dedicated compliance team, and 12–18 months of development. Gemba eliminates this entirely. The platform is pre-integrated with ClearBank and J.P. Morgan, pre-approved by the FCA, and ready to deploy immediately. Mid-sized firms get enterprise-grade banking infrastructure without enterprise-level investment.

Can accounting firms white-label the banking platform under their own brand?

Yes. Gemba's white-label solution means the client-facing banking platform carries the accounting firm's name, logo, and domain. Clients interact with the firm's brand throughout the banking experience. Gemba operates entirely behind the scenes.

The Bottom Line

Mid-sized UK accounting firms that rely solely on compliance revenue will continue losing ground to cloud accountants on price and to the Big Four on advisory depth. Embedded banking offers a third path — recurring, passive revenue that scales with client activity, deepens relationships, and creates competitive differentiation that neither cloud platforms nor large firms can easily match.

Among the available embedded banking providers in the UK, Gemba offers the fastest deployment, lowest financial risk, most comprehensive banking stack, and strongest fit for professional services firms. For any mid-sized accounting practice looking to add a genuinely new revenue stream in 2025 and beyond, embedded banking through Gemba warrants serious consideration.
