1. The owner is the firm
Every client would name the owner as their contact; the owner signs everything, prices everything, and holds every relationship. A buyer reads that as: the asset leaves in the seller's car. Diligence question they will ask: "What happens to retention if you disappear for 90 days?"
2. The book came from two referral sources
Half the business clients trace to one attorney and one banker, both personal friends of the seller. Concentrated origin means the growth engine retires with the owner. Most owners cannot answer "where did your book actually come from" with data, which is why the revenue-origin map is the second artifact of our diagnostic.
3. Nothing is written down
No SOPs, no workflow documentation, no client-onboarding checklist. The buyer is not buying what the firm does; they are buying their ability to keep doing it without you. Undocumented process converts directly into earnout length and clawback clauses.
4. The fees are ten years old
Loyal clients at legacy prices look like goodwill to the seller and like repricing risk to the buyer: the moment fees normalize, some book walks. Underpricing suppresses both the multiple and the number it multiplies.
5. The firm's own books are a mess
The cobbler's children, every time. No clean P&L by category, no client-level revenue report, AR aging nobody has looked at since 2023. A buyer who prepares financial statements for a living will not buy a firm that cannot produce its own.
