If fractional acquisition has a default move, it's the tuck-in: adding one capability — a line, a carrier, a small cluster of accounts — to a book you already operate. It's the cleanest pattern because almost everything that makes whole-agency integration risky is absent. You're not inheriting an organization; you're slotting a defined piece into a machine that already runs. The discipline is in treating it as a repeatable playbook so you can run several without reinventing the deal each time.
§ 01 · The four-phase playbookThesis to close.
A tuck-in runs in four phases. Thesis is internal alignment on what you're actually trying to accomplish — and four "why" drivers shape how picky you can be. Demand-pull (customers are asking for the line, which lets you be selective about carrier fit), supply-push (appointments are available and you want to fill them), competitive catch-up (everyone else has it, which pushes you toward any carrier and any book), and relationship preservation (a producer is leaving and you want to retain the book). Target identification is sourcing plus a three-screen filter. Offer construction is valuation, structure, and transition support. Close and integration is the 30–60 day cycle that takes the deal from signed to operational. Naming the "why" first matters because it sets your tolerance: a demand-pull buyer can hold out for perfect carrier fit, while a competitive-catch-up buyer takes a wider book.
§ 02 · The three screensWhat qualifies a slice.
| Screen | Clean | Friction / warning |
|---|---|---|
| Carrier fit | Already appointed — zero friction | Unappointed — onboarding + change-of-agent + relationship work |
| Geography fit | Already licensed — clean | Unlicensed — state license needed (usually cleaner than carrier onboarding) |
| Retention profile | 3-year above 90% — strong | Below 70% — weak forward retention likely |
Three sourcing channels feed the pipeline: continuous profile matching (the fastest path, since your buyer profile runs against available books constantly), direct relationships with other agencies, and brokers or advisors (less efficient, but productive). Whatever the source, every candidate passes the same three screens. Carrier fit: an appointed carrier is zero friction; an unappointed one means onboarding, change-of-agent paperwork, and relationship-building. Geography fit: a licensed state is clean; an unlicensed one needs a license, which is usually cleaner than carrier onboarding. Retention profile: a three-year retention above 90% is strong, while below 70% signals weak forward retention. These three are the difference between a slice you can absorb in 45 days and one that quietly becomes a project. The profile that feeds the matching is built in the buyer profile.
§ 03 · Pricing and structureCommission multiples, not EBITDA.
Slices price on a multiple of annual commission, not an EBITDA multiple. A typical $100K–$300K tuck-in runs 0.5–1.0× annual commission, with the exact point set by retention, carrier fit, client concentration, and geography. The standard structure is cash at close (or installments tied to retention) plus a ~10% holdback released if retention clears 85% at twelve months — a mechanism that puts real money behind the retention assumption.
Tuck-in pricing runs 0.5–1.0× annual commission for a typical $100K–$300K premium slice, with the multiple set by retention strength, carrier fit, client concentration, and geographic spread — not by a traditional EBITDA multiple. The standard structure is a simple purchase agreement with cash at close (or installments tied to retention), a roughly 10% holdback released if retention clears 85% at the twelve-month mark, and earnouts only rarely on small slices. Four transition-support requirements belong in the purchase agreement: 30–60 days of seller access post-close for client questions; seller participation in the initial client communication; seller help with carrier change-of-agent paperwork; and a seller commitment not to solicit the transferred policies back. A worked illustration: a P&C agency adding commercial auto runs its profile, the matching surfaces three commercial-auto slices in three months, it picks a $110K-premium book at 87% retention concentrated on one preferred carrier, prices it at 0.75× commission (~$82.5K), and offers $80K cash plus an $8K holdback at twelve months if retention beats 85%. The deal closes in 45 days, retention sits at 86% by month four, the holdback releases — total cost $88K for $110K of premium at 87% retention.
§ 04 · Integration on the clockThe 30–60 day cycle.
The integration timeline has three windows. Pre-close (T-14 to 0): diligence, management-system prep, a service-team brief, and client-communication prep. Day 0–7: execute the purchase agreement, file carrier paperwork, transfer the book into the management system, and send the client communication. Day 7–90: monitor the first renewal cycle, support the client transition, onboard the producer, and finalize carrier paperwork. The LOI-to-fully-operational target is 30–60 days for a well-executed tuck-in, and that target is also a diagnostic: a deal that drags well past it is usually signaling a problem in carrier onboarding, client transition, or the seller's cooperation. Run the tuck-in as a timed, screened, structured play and it becomes the move you can repeat — the building block of a portfolio rather than a one-off. The diligence depth that fits a slice this size is in producer-book acquisitions, the closest sibling pattern.

- Adding a defined capability — a line, carrier, or account cluster — to a book you already operate; the cleanest slice pattern.
- The four "why" drivers
- Demand-pull, supply-push, competitive catch-up, and relationship preservation — they set how selective you can be.
- The three screens
- Carrier fit, geography fit, and retention profile — the qualifiers that separate an absorbable slice from a project.
- Commission multiple
- Slice pricing basis — 0.5–1.0× annual commission for a typical tuck-in, not an EBITDA multiple.
- Retention holdback
- ~10% of price held back, released if retention clears 85% at twelve months — money behind the retention assumption.
- Transition support
- The four contractual seller obligations — post-close access, client intro, carrier paperwork, no re-solicitation.
