The five-pillar due diligence framework — before the retrade.

Due diligence is phase three's core, and its real function is to price the deal correctly before the buyer is committed — because the alternative is a retrade. A retrade is a 10–30% price reduction the buyer demands late in the process after uncovering messy records, hidden liabilities, or compliance gaps; strong pre-LOI diligence compresses that risk by surfacing the problems while there's still room to walk or reprice cleanly. The framework spans five pillars, each one a cluster's worth of depth on its own, and the navigator's job is to know what each pillar screens for and which checks are non-negotiable.

§ 01 · The five pillarsThe full sweep.

Each pillar has its own deep cluster — financial, carrier, and customer diligence each run dozens of detailed checks. The framework's value at the navigation level is the discipline of covering all five rather than over-indexing on the financials and skipping the cultural and technology pillars that drive the post-close failure rate. Five killer-risk categories follow from skipping diligence: retrading, overpaying for unsustainable earnings, client exodus post-close (from concentration and producer non-compete gaps), regulatory and fiduciary violations, and integration nightmares from incompatible tech and culture mismatch.

§ 02 · The two deal-killersTrust and reconciliation.

The trust ratio and the reconciliation are the screens that come first because they're binary. An agency holds premium in trust that isn't its money, so a trust ratio below 1.0 means the agency is operating with a trust deficit — a fiduciary problem the buyer would inherit, and a deal-killer regardless of how attractive the rest of the book looks. The three-way reconciliation is the integrity check: if the bank, the checkbook, and the ledger don't agree, the financials can't be trusted at all, and there's no point diligencing the rest until they reconcile. Running these two screens first saves a buyer from diligencing a deal that was never viable.

§ 03 · The thresholdsWhat clean looks like.

A set of thresholds turns the operational and carrier pillars into concrete screens. Retention should clear 85% annually — request a trailing 36-month retention by line of business and producer. EBITDA margins of 20–30% are healthy; under 15% signals bloat and inefficiency, while over 45% is a red flag for underinvestment in staff or service that will surface as future churn. Single-client concentration above 15% is a flight risk; single-carrier concentration above 40% is platform-dependency risk. A loss ratio above 60% on an upward trend means contingency bonuses will likely drop to zero next year — so exclude them from the valuation. And for lender financing, DSCR must clear 1.25×. The carrier pillar adds a documentation requirement: three years of contingency-bonus payments, commission schedules, and change-of-control language for the top five carriers.

§ 04 · Diligence as repricing leverageThe retrade, reversed.

The framework reframes diligence from a cost into leverage. A buyer who does strong pre-LOI diligence isn't just protecting against surprises — they're building the documented basis to reprice cleanly if a finding warrants it, rather than scrambling for a retrade late when the leverage has shifted to the exhausted seller. The EBITDA-margin diagnostic illustrates the read: a margin under 15% isn't just low, it's a signal of bloat the buyer can fix (an operational-arbitrage opportunity) or a sign of hidden problems; a margin over 45% isn't just high, it's a warning that the agency has underinvested in the service that retains clients. Each pillar produces both a screen and a story, and the buyer who runs all five enters negotiation with the evidence to defend their number — the opposite of the buyer who skipped diligence and is now demanding a 10–30% retrade nobody believes.
