Accounting Firm Valuations: What Buyers Pay

The Valuation Landscape Has Changed

Accounting firm valuations in 2026 look nothing like they did five years ago. What was once a predictable market — firms trading at 1.0x to 1.2x gross revenue based on partner transition timelines — has become a multi-tier pricing environment where technology, specialisation, and PE interest drive fundamentally different outcomes.

Understanding where your firm (or your acquisition target) falls on this spectrum is essential for anyone advising on, buying, or selling professional services businesses.

Traditional Revenue Multiples

The legacy pricing model for accounting firms was straightforward. Firms were valued at approximately 1.0x to 1.2x gross revenue, with variations driven primarily by client retention risk, partner age, and geographic market quality.

This model assumed that accounting firm revenue was essentially partner labour — tied to individual relationships, billable hours, and manual compliance work. Under this framework, a USD 10 million revenue firm was worth USD 10-12 million, with the buyer effectively purchasing a book of business and a team of professionals.

According to Firmlever, this traditional model still applies to firms that remain service-oriented without meaningful technology integration or specialisation. But an increasing proportion of transactions are breaking free of these constraints.

The Technology Premium: Up to 2.5x Revenue

The most significant shift in accounting firm valuations is the emergence of a technology premium. Firms with proprietary AI tools, automated workflows, or cloud-native platforms are commanding multiples that detach from traditional revenue benchmarks.

Firmlever’s 2026 analysis identifies firms with proprietary technology commanding up to 2.5x revenue — more than double the traditional multiple. The logic is that proprietary technology transforms a service business (where revenue scales linearly with headcount) into a technology business (where revenue can scale without proportional cost increases).

What Qualifies as a Technology Premium

Not all “technology” creates valuation uplift. The premium applies to:

• Proprietary AI tools — custom-built models for tax optimisation, audit automation, or industry-specific analysis (e.g., real estate cost segregation AI)
• Automated compliance workflows — platforms that handle tax preparation, regulatory filing, or financial statement generation with minimal human intervention
• Client-facing SaaS platforms — portals, dashboards, or analytics tools that clients interact with directly, creating switching costs and recurring subscription revenue
• Data assets — structured datasets from years of client engagements that train AI models or enable benchmarking services

Firms that simply use third-party software tools (QuickBooks, Xero, CCH) do not receive a technology premium. The premium is for proprietary technology that constitutes defensible intellectual property.

As Marc Howard of Firmlever put it: “Your code is worth more than your timesheets.”

PE Platform Multiples: 8x to 13x EBITDA

At the top of the market, PE-backed platform acquisitions of large accounting firms are transacting at EBITDA multiples of 8x to 13x. The Baker Tilly and Moss Adams merger in April 2025 — valued at approximately USD 7 billion — demonstrated the magnitude of capital flowing into the sector.

These elevated multiples reflect several factors:

• Scale economies — larger firms benefit from shared infrastructure, centralised compliance, and technology deployment across a broader revenue base
• Multiple expansion — PE buyers acquire firms at lower multiples and create value through operational improvement, then exit at higher platform-level multiples
• Market scarcity — the number of Top 100 accounting firms available for sale at any given time is limited, creating competitive tension among PE buyers

The Roll-Up Math

The PE roll-up model works because of the spread between acquisition multiples and platform multiples. A PE firm might:

1. Acquire a platform firm at 8-10x EBITDA
2. Execute bolt-on acquisitions at 4-6x EBITDA
3. Invest in technology and operational improvements to grow margins
4. Exit the combined platform at 10-13x EBITDA

The value creation comes from buying smaller firms at lower multiples and integrating them into a platform that commands a higher blended multiple. This is why mid-sized firms — those with USD 5-20 million in revenue — are seeing unprecedented buyer interest from PE-backed platforms.

What Drives Premium Valuations

Beyond the tier of the buyer, specific firm characteristics push valuations to the top of each range. Dealmakers conducting comparable company analysis or advising on sell-side transactions should evaluate:

Revenue Quality

• Recurring vs. project-based — firms with high percentages of annuity-style engagements (monthly bookkeeping, annual audit, ongoing advisory) command premiums over those dependent on project-based work
• Client concentration — firms where no single client represents more than 5-10% of revenue are less risky and more valuable
• Revenue growth trajectory — consistent organic growth signals market demand and pricing power

Specialisation

Vertical specialisation is one of the strongest valuation drivers. According to Hollinden Investment Banking, “Firms without distinct service lines or industry focus areas will increasingly struggle to command premium valuations.”

Firms specialising in high-growth verticals — healthcare, real estate, cannabis, cryptocurrency, government contracting — command meaningful premiums over generalist firms. The specialisation creates pricing power, client stickiness, and defensible market positions.

Staff and Leadership Quality

Post-merger integration risk is the single biggest concern for acquirers of professional services firms. Key personnel — partners, senior managers, and client-facing staff — are the assets being acquired. Firms with:

• Strong management below partner level — reduces key-person dependency
• Low staff turnover — signals healthy culture and competitive compensation
• Documented processes — enables integration without knowledge loss
• Non-compete agreements — protects against post-sale attrition

Quality of Earnings Factors

Sophisticated buyers (and their due diligence advisors) scrutinise:

• Partner compensation normalisation — owner compensation often includes distributions, personal expenses, and above-market draws that overstate true earnings
• Work-in-progress (WIP) — unbilled time represents both an asset (future billing) and a risk (write-off exposure)
• Billing realisation rates — the percentage of standard rates actually collected signals pricing discipline
• Client engagement letters — the strength and enforceability of client contracts affects revenue durability

Positioning for Maximum Value

Firm owners considering a sale in the next 2-5 years can take specific steps to maximise their valuation:

1. Invest in proprietary technology — even modest AI tools or automated workflows can shift a firm from the service tier to the technology tier
2. Deepen vertical expertise — pick 2-3 industry verticals and build defensible market positions
3. Reduce partner dependency — develop the next generation of leadership and shift client relationships to the firm, not individual partners
4. Clean up financials — normalise partner compensation, resolve WIP backlogs, and ensure clean quality of earnings reporting
5. Build recurring revenue — shift from one-off engagements to subscription or retainer-based relationships where possible

What This Means for Dealmakers

For M&A advisors and investors evaluating accounting firm opportunities:

• The valuation gap is real — there is no single “market multiple” for accounting firms in 2026. A traditional compliance firm and a tech-enabled advisory firm in the same revenue range can have a 2x valuation difference
• Technology due diligence matters — evaluating the quality and defensibility of proprietary technology is as important as financial due diligence
• Specialisation premium is durable — vertical expertise creates sustainable competitive advantages that survive market cycles
• Earnout structures bridge gaps — where buyer and seller disagree on fair value, performance-based earnouts tied to revenue retention and growth can align incentives
• APAC is undervalued — accounting firms in Australia, Singapore, and India trade at discounts to comparable US firms, creating cross-border M&A opportunities for global platforms

The accounting firm M&A market rewards preparation, differentiation, and technology investment. Firms that understand what buyers value — and position accordingly — will capture the premium end of the valuation spectrum.
