Accounting & CPA Business Valuation

Accounting & CPA businesses are typically priced on one of two earnings figures depending on size: Seller's Discretionary Earnings (SDE) below roughly $1M, and EBITDA above. Applied to accounting & cpa specifically, the base multiple ranges are 1.5x–2.75x SDE and 3.5x–6.5x EBITDA. Where inside that range your business trades is decided by a handful of specific, buyer-visible factors.

The accounting industry crossed a threshold in 2021 when TowerBrook took a majority stake in EisnerAmper — the first time a top-100 CPA firm went PE. Since then Ascend Partner Firms (backed by Alpine Investors), Aprio (Charlesbank), Baker Tilly (Hellman & Friedman + Valeas), Springline Advisory, Rise Growth Partners, Elliott Davis, and Citrin Cooperman have deployed billions to consolidate mid-market accounting. Sub-$5M-revenue independent firms are the primary bolt-on target. Multiples have moved from historical 1.0–1.2x revenue (or 4–6x EBITDA) to 1.4–1.8x revenue / 8–12x EBITDA for firms with strong recurring compliance work, an advisory practice, and demonstrable partner-succession bench. The CPA talent shortage is the single biggest structural tailwind — every acquirer is buying people at least as much as they're buying revenue.

What moves the multiple

Accounting & CPA valuation drivers

Industry sets the base range. These specific business-level factors move you up or down inside it.

Recurring compliance revenue percentage

Percentage of revenue from recurring engagements — monthly bookkeeping, quarterly reviews, annual tax + audit compliance. 70%+ is the threshold that turns a project-shop into an annuity buyers will pay premium multiples for.

Advisory / CAS revenue mix

Percent of revenue from client accounting services (CAS), CFO / controller outsourcing, and higher-value advisory work. Buyers pay premiums for firms that have transitioned beyond commodity 1040s and 1120s.

Partner-succession bench

Number of non-owner senior managers or partners on track to buy in. Owner-only firms trade at meaningfully lower multiples because the buyer inherits full succession risk.

Client concentration

Percentage of revenue from the top 10 clients. Buyers discount firms with above 25% concentration in any single client and heavily discount above 40%.

Vertical specialization

Firms with a dominant vertical (construction, medical, real estate, dental, cannabis, ERC-adjacent) command premiums to generalist firms because the client base is stickier and the expertise doesn't commoditize.

Deal structure

How accounting & cpa deals close

Structures vary widely by firm size. Sub-$2M revenue firms typically close as asset sales with a 20–40% cash-at-close / balance in a 3–5 year earn-out tied to client retention. $2–10M firms increasingly close as stock/equity deals with the seller rolling 20–40% equity into the acquiring platform and a 3–5 year employment agreement. PE-backed platforms have institutionalized playbooks: standardized diligence packets, aggressive transition periods (partners typically stay 3–5 years post-close), and structured earn-outs tied to revenue retention and net-new advisory revenue. The deal doesn't happen without a credible succession plan for partner-owner workload transfer.

Common questions

Accounting & CPA valuation FAQ

How is my accounting firm valued?

The market prices in both revenue multiples and EBITDA multiples in parallel. Sub-$2M revenue firms trade at roughly 1.0–1.4x annual revenue (or 4–7x EBITDA). Firms above $2M with 70%+ recurring compliance revenue and a real advisory book trade at 1.4–1.8x revenue / 8–12x EBITDA. Vertical specialization, staff retention, and partner-succession bench are the biggest multiple drivers at every scale.

How long does it take to sell an accounting firm?

Plan on 6–10 months from initial outreach to close. PE-backed acquirers move quickly on well-prepared firms (60–90 days from LOI to close) but the up-front prep — cleaning up your KPI reporting, documenting your CAS/advisory revenue split, and getting your partner-succession story straight — is where 3–4 months of the timeline hides.

What drives higher multiples for accounting firms?

In order of impact: (1) recurring compliance revenue above 70%, (2) a real advisory / CAS practice contributing 20%+ of revenue, (3) at least one non-owner partner or senior manager on the succession track, (4) vertical or niche specialization, (5) low client concentration (top-10 clients under 25% of revenue), (6) a technology stack modern enough that a buyer platform can absorb you without a rip-and-replace.

Should I sell to a PE-backed platform or a regional firm?

PE-backed platforms (Ascend, Aprio, Springline) offer the highest headline multiples but require 3–5 year post-close commitments and structure with heavier earn-outs and equity rollover. Regional firms typically offer cleaner cash-at-close at slightly lower multiples. Partners planning to retire within 24 months are usually better served by a regional firm; partners with 5+ years of runway who want a second bite at the apple often prefer the PE platforms.

What kills an accounting-firm deal in diligence?

Three things dominate: (1) inability to disaggregate compliance, CAS, and advisory revenue in your financials — buyers can't price what you can't segment, (2) undisclosed staff departures during the process (turnover is a live-wire diligence item in the CPA-shortage environment), (3) a partner-owner who's on every material client relationship — that's inherited transition risk, not a firm to buy.
