Buyers overlook that the top 5 clients represent over 40% of revenue. If one or two leave post-close, EBITDA collapses and your earnout becomes worthless.
How to avoid: Request a full client revenue breakdown. Require earnout protections tied specifically to retention of clients exceeding 10% of total billings.
Many CPA firms run entirely through the founding partner's relationships. Buyers assume a 90-day transition is sufficient when 18–24 months is typically required.
How to avoid: Verify that staff CPAs hold independent client relationships. Negotiate a 12–24 month seller transition with milestone-based earnout tied to documented handoffs.
Acquiring a firm without confirming staff CPA credentials and enforceable non-solicitation agreements exposes buyers to losing both talent and clients simultaneously.
How to avoid: Audit all staff licenses through state CPA boards. Confirm non-solicitation agreements are signed, current, and legally enforceable in the relevant jurisdiction.
Buyers apply standard 1.0–1.4x revenue multiples without separating recurring tax and bookkeeping retainers from one-time advisory or audit engagements.
How to avoid: Segment revenue into recurring versus project-based streams. Apply higher multiples only to contracted, repeating engagements with signed client agreements.
Outdated practice management software and undocumented workflows create operational chaos after closing, increasing staff frustration and client service failures.
How to avoid: Evaluate the existing tech stack including tax software and practice management tools. Budget for integration or migration costs before finalizing your offer price.
Vague earnout agreements tied to total revenue allow sellers to dispute calculations and create post-close disputes that damage the working relationship.
How to avoid: Define earnout triggers by named client retention, billing hours per account, and gross fees collected. Use a third-party accountant to track and verify metrics.
Buyers submit SBA loan applications before independently verifying the Accounting/CPA Firm's normalized EBITDA. When diligence reveals add-backs that don't hold, the deal's debt service coverage collapses and the loan fails underwriting.
How to avoid: Build your EBITDA model with conservative add-back assumptions before engaging an SBA lender. At current rates, a $1M SBA 7(a) loan costs approximately $13,000/month — the Accounting/CPA Firm needs $195,000+ in post-salary EBITDA to clear 1.25x DSCR.
Buyers close on a Accounting/CPA Firm assuming operations transfer smoothly, then discover undocumented processes, informal vendor relationships, and staff who rely on institutional knowledge the seller carries in their head.
How to avoid: Require a 60-day operational documentation period before closing. Walk through every key process with the seller present, document staff responsibilities, vendor contacts, and customer communication protocols. Build a 90-day integration plan before the wire hits.
What experienced buyers verify before committing to a Accounting/CPA Firm acquisition.
The specific concerns and miscalculations buyers face in this industry.
Common miscalculations sellers make that reduce their final price or derail a deal.
Most CPA acquisitions use a 12–24 month earnout tied to client revenue retention, typically paying 80–90% upfront with the remainder contingent on retaining named accounts above a defined threshold.
Yes. CPA firms are SBA 7(a) eligible. Most buyers finance 80–90% through SBA loans with a seller note covering the remainder, provided the firm has documented recurring revenue and clean financials.
Industry norms suggest 5–15% attrition in year one. Attrition spikes above 20% when the founding CPA exits abruptly or staff CPAs haven't been introduced to clients pre-close.
Lower middle market CPA firms typically trade at 0.9x–1.4x revenue. Firms with high recurring retainer revenue, diverse client bases, and licensed staff command multiples at the higher end of that range.
