Stage 8 of 8
Close & transition
Wire the money, win the room, and spend the first 100 days learning before changing.
Closing is mechanics; the transition is the test. Day one is about communication — employees, customers, suppliers, each hearing the right message from the right person. The first 100 days are about learning the business you now own, holding the seller to written transition commitments, and installing your own cash controls immediately while resisting the urge to change everything else.
Questions to answer before moving on
- What do employees, customers, and suppliers hear on day one — and from whom?
- What will I deliberately not change in year one?
- Are banking and cash controls mine from hour one?
- What exactly does the seller owe me post-close, in writing?
Mistakes that cost searchers months
- Big changes in month one that trigger key departures
- Letting the seller relationship lapse the day after wiring
- Running the old owner's cash habits instead of installing your own

Verified against primary sources, pros and cons included. Full write-ups in the directory.
A marketplace and concierge service that matches small-business buyers with vetted independent professionals and boutique firms for quality of earnings, legal, technical, and operational due diligence, plus pre-LOI and post-acquisition work; you describe your project and receive multiple scoped proposals within roughly 36 hours to 3 business days. Buyers pay nothing to use it — DueDilio takes a commission from the service providers it places.
Our take: A legitimately free, founder-run way for first-time searchers to get competing QoE, legal, and diligence proposals in days — use it for speed and price discovery, but remember it's paid by the providers it recommends, so benchmark at least one outside quote.
Free · Free for buyers, per the vendor's own FAQ ("DueDilio is free for clients to use. Our revenue comes from the service providers in our network," homepage as captured Apr 2026; how-it-works FAQ adds it "earns revenue by taking a commission on the transactions facilitated"). No buyer-side subscription or platform fee is published; you pay only the hired provider's quoted engagement fee (DueDilio's own guides peg small-business financial DD at roughly $5k–$20k+). No dedicated pricing page exists.

An insurance brokerage with a dedicated ETA vertical — insurance due diligence on acquisition targets pre-close, then property & casualty, benefits, and life coverage for the acquired company, serving search funds, family offices, and private equity.
Our take: Put insurance diligence on your pre-close checklist and have a specialist like Oberle run it — then get a second brokerage quote post-close.
Custom pricing · No pricing or fee disclosure published; insurance brokerage is conventionally commission-based via carriers. Diligence engagement terms on inquiry (site checked 2026-07-10).

A nationwide M&A law firm built specifically for small business acquisitions — representing searchers, sponsors, and investors — with a dedicated 'Main Street Express' offering for sub-$1M deals and fractional general counsel post-close.
Our take: The default shortlist for searcher deal counsel — just get the fee quote early, since pricing isn't public.
Custom pricing · No pricing published — the site claims 'transparent fees' but lists no figures; engagements are quoted on contact. Main Street Express targets sub-$1M purchases (verified on smblaw.group 2026-07-10).

The standard playbook for leadership transitions — diagnosing the situation you're inheriting, securing early wins, and building credibility fast. Written for executives entering new roles, it maps remarkably well onto taking over a just-purchased business.
Our take: Read it during diligence so the transition plan exists before day one.
One-time · Book — hardcover around $30 retail; widely available in all formats (HBR Press, updated & expanded edition).

The book behind the Entrepreneurial Operating System (EOS) — a simple operating cadence (scorecards, weekly L10 meetings, quarterly rocks, accountability charts) that hundreds of thousands of small companies run on, and a common choice for new owners installing structure post-acquisition.
Our take: The default post-close operating system — install it in month 4, not week 1.
One-time · Book — paperback typically around $20 retail (Simon & Schuster / BenBella; varies by retailer). The broader EOS ecosystem (implementers, software) is a separate, significant cost.
