The pattern in our work is consistent: accountants are excellent at running practices and relatively inexperienced at selling them. The mistakes below are not about intelligence — they are about not having transacted before. Read in order. Each one compounds the next.

  1. Waiting too long to start the plan

    By far the most common — and most costly — mistake. Owners decide to retire, look for a buyer six months out, and discover that an exit done in twelve months sells for materially less than the same practice prepared over three to five years. Multiples drop, deal structure shifts in the buyer's favor, retention guarantees get tougher, and there is no time left to fix concentration risk or staff gaps.

  2. Telling staff or clients too early

    The moment your staff knows you intend to sell, the most marketable ones begin updating their resumes. The moment your clients know, the competitors closest to them start calling. Premature disclosure has killed more deals than any single price disagreement we have seen. Confidentiality, sequencing, and prepared messaging are non-negotiable.

  3. Believing the headline multiple

    "I'll get 1.2× revenue" is a useful starting frame and a dangerous endpoint. Two practices with identical revenue sell for very different real proceeds depending on revenue mix, client concentration, average fee, recurring share, billing realization, staff stability, and the structure of the deal itself. Anchoring on a multiple before the practice has been properly valued sets you up to negotiate against your own number.

  4. Underestimating client concentration

    When the top ten clients drive 35% or more of fees, buyers price in attrition risk aggressively — and so does any retention guarantee written into the deal. Owners who do not see this until a buyer's offer arrives often discover that 18 months of diversifying would have lifted the price by 10–15%. Look at your concentration honestly, early.

  5. Letting the buyer dictate the structure

    A first draft of a term sheet almost always allocates the deal in the buyer's favor: modest cash at close, a long earn-out, a stiff retention clawback, and a non-compete broader than necessary. Owners who accept the first structure as a baseline rarely recover. The structure of the deal is at least as important as the price and should be negotiated with the same attention.

  6. Ignoring the tax allocation

    Buyers prefer to allocate purchase price toward fixed assets and consulting income — producing depreciation and ordinary-expense treatment for them. Sellers prefer allocation to goodwill — producing capital-gain treatment. The default allocation in most APAs is wrong for the seller. Owners who don't engage a tax advisor before the term sheet is signed routinely pay 15–25% more in tax than they needed to.

  7. Treating it as a transaction instead of a transition

    A successful sale is not the day the wire arrives — it is the day, twelve to twenty-four months later, when the retention period ends and the practice has stuck. Owners who mentally check out at closing watch attrition spike, retention clawbacks trigger, and relationships with former clients sour. The transition is the deal.

  8. Negotiating without representation

    The buyer almost always has an attorney, an accountant, and (frequently) a broker on their side. The seller, alone, is negotiating a transaction they will do exactly once. The asymmetry is enormous. Even sellers who don't engage a full-service broker should retain, at minimum, an attorney experienced in accounting practice sales and a tax advisor — preferably someone other than themselves.

  9. Not preparing the books for diligence

    The first buyer who looks at a poorly-organized chart of accounts, mixed personal and business expenses, or undocumented add-backs will discount the practice — and often walk. Books prepared for a CPA owner are not the same as books prepared for an acquirer. Three to twelve months of clean-up work, normalizing add-backs, separating revenue streams, and documenting recurring vs. one-time fees, pays back in multiples.

  10. Selling to the first buyer who shows up

    The first credible offer feels like a finish line. It almost never is. A single offer is a data point; competitive offers are leverage. Owners who run even a modest, confidential process with three to five qualified buyers consistently realize better terms — not because of bidding war dynamics, but because each buyer knows others are present. This is where a specialized accountant business broker pays for itself many times over.

The owners who avoid these ten mistakes share a single trait: they began their succession plan three or more years before they wanted to be done. Time is the cheapest, most powerful variable you have. The earlier you start, the more of it you control.
