30 Lessons From 30 Business Sales — What I've Learned Closing M&A Deals

After working through dozens of business sales across industries — from pest control and HVAC to veterinary practices, waste management, dental groups, and commercial real estate — I've noticed that the same patterns repeat. The deals that close cleanly and at full value are rarely the ones with the most complex structure. They're the ones where the seller prepared seriously, ran a competitive process, and avoided the handful of mistakes that derail transactions at predictable points. What follows are 30 lessons from those transactions — the observations I find myself sharing with clients again and again before they go to market.

This article is for business owners at any stage of thinking about an exit — whether you're five years out and starting to plan, or you've already received an unsolicited offer and you're wondering what to do next. These lessons apply across industries and deal sizes.

On Preparation

1. The best time to start preparing is three years before you plan to sell. The levers that move valuation the most — owner dependency reduction, recurring revenue growth, customer concentration improvement — take time to implement. Starting the day you decide to sell is too late to move those needles meaningfully.

2. Clean financials are worth more than any other preparation investment. Three years of tax returns that reconcile cleanly to your P&L, with owner add-backs documented and defensible, will save you more in buyer negotiations than almost anything else. Buyers discount what they can't verify.

3. Know your SDE or EBITDA number before your first buyer conversation. Too many sellers enter conversations without a clear, recasted earnings figure. When a buyer asks what you make, the answer "well, it depends on how you count it" is a red flag that invites them to count it in the most conservative way possible.

4. Understand your lease before you list. A lease that expires in 18 months, or a landlord who has never agreed to a transfer clause, is a deal problem — and it's better to know about it and solve it before a buyer finds it in diligence.

5. Don't confuse revenue with value. A $3 million revenue business with 10% EBITDA margins is worth less than a $2 million revenue business with 30% EBITDA margins. Buyers buy earnings, not revenue. Know the difference.

6. Reduce owner dependence before you go to market. If every key customer relationship, every key vendor relationship, and every key employee relationship runs through you personally, buyers will price that risk into their offer — or walk. Transitioning relationships to your management team before a sale process is one of the highest-return uses of pre-sale time.

7. Fix the things you've been deferring. That equipment you've been meaning to replace, the website you keep saying needs updating, the employee handbook that hasn't been touched since 2017 — buyers notice deferred maintenance in every part of a business, and it tells a story about operational discipline that is hard to reverse in a diligence conversation.

On Running a Process

8. Never take the first offer. Unsolicited offers are almost always below market. The buyer who approaches you directly knows something you don't: they know there's no competition for your business yet. A properly run competitive process almost always produces better outcomes than a bilateral negotiation.

9. Confidentiality is not optional — it's essential. Word getting out to your employees, customers, or competitors that you're selling can cause real damage before a transaction closes. A properly structured confidential marketing process with signed NDAs before any information is shared is not bureaucratic overhead — it's protection for your business and your employees.

10. More buyer conversations create better outcomes. Every additional qualified buyer in a process increases competitive tension and improves your leverage on price, terms, and deal structure. Selling to the first interested party because you're tired of the process is one of the most expensive decisions a business owner can make.

11. A letter of intent is not a deal. LOIs are non-binding and frequently change between signing and close. Don't slow down operations, tell employees, or make major financial decisions based on a signed LOI. Focus on getting to a signed purchase agreement and a funded transaction.

12. Price is not the only term that matters. Deal structure — earnout provisions, seller financing, escrow holdbacks, non-compete terms, post-closing employment obligations, representations and warranties — can affect your net outcome as much as the headline price. Evaluate the full deal, not just the number at the top.

13. The right buyer is not always the highest bidder. A buyer who is well-capitalized, has a clear integration plan, and can close without contingencies is often a better choice than a higher headline price from a buyer with financing uncertainty or unrealistic expectations about what they're buying.

14. You can negotiate harder than you think. Most sellers underestimate their leverage, particularly once a buyer has signed an LOI and is deep into diligence. At that point, the buyer has sunk cost and emotional investment in the deal, and reasonable requests are usually accommodated. The key word is "reasonable."

On Diligence and Close

15. Diligence takes longer than the buyer says it will. Budget 60–90 days for a serious diligence process and plan your life accordingly. Trying to rush diligence creates mistakes, and mistakes in diligence create price retrading.

16. Organize your documents before diligence starts. A clean virtual data room with organized financial records, contracts, employee files, equipment lists, and permits tells a buyer that you run a professional business. Disorganized records — the opposite of this — create buyer anxiety and fuel requests for more information.

17. Surprises in diligence kill deals. If there is something in your business that a buyer will find during diligence — a pending lawsuit, a customer who is leaving, an equipment problem, a key employee who has indicated they might not stay — disclose it proactively with context, rather than letting the buyer discover it. Buyers can handle most issues with context; they cannot handle the feeling that information was concealed.

18. Price retrading is usually a signal, not a negotiating tactic. When a buyer comes back after diligence with a lower price, they have usually found something that genuinely changes their view of the business risk. Sometimes it's a negotiating tactic, but often it's real. The best defense is diligence-ready financials and no hidden issues.

19. Your M&A attorney matters more during close than at any other stage. The purchase agreement is the governing document for everything that happens post-close — representations and warranties, escrow provisions, indemnification caps, basket thresholds. An attorney who doesn't do this regularly will miss things that cost you money later.

20. SBA financing adds timeline, not just complexity. SBA-financed transactions typically take 30–60 days longer than conventional deal closes. Build that into your expectations and your planning. If you need to close by a specific date for tax or personal reasons, communicate that early and choose buyers whose financing timeline is compatible.

On Post-Close and Life After the Sale

21. Negotiate your transition period carefully. A 90-day transition assistance period is standard. A 2-year employment agreement with performance-linked earnouts is a very different commitment. Know what you're agreeing to and make sure the compensation for your post-close time reflects the obligation you're undertaking.

22. Earnouts are not the same as sale proceeds. Earnout payments contingent on future performance are real money — but they come with risk. The business you no longer control will need to hit specific metrics you negotiated before signing. The more an earnout represents of your total consideration, the more carefully you need to negotiate the measurement criteria and dispute resolution provisions.

23. Non-competes are real. Read them. Understand them. A two-year, 50-mile non-compete in your specific industry is not the same as a five-year, 200-mile restriction that prevents you from working in your field. These are negotiable, and negotiating them seriously is worth the effort.

24. Plan for taxes before you close, not after. The tax implications of your transaction — capital gains treatment, depreciation recapture, allocation of purchase price, installment sale treatment of seller financing — should be modeled by your CPA before you sign. Post-close is too late to restructure for tax efficiency.

25. Tell your key employees at the right time. Telling employees too early creates anxiety and attrition risk. Telling them too late — so they find out from someone else — destroys trust and can cause the exact attrition you were trying to prevent. Work with your advisor to design a communication plan that is timed to the close.

On Mindset and the Long Game

26. Seller fatigue is a real deal risk. Long transaction timelines cause sellers to make concessions they wouldn't make fresh. Maintaining your energy and resolve through a 9–12 month process is part of the discipline of a well-executed exit.

27. The sale is not the end of your identity. For many business owners, the sale of a business they built over decades is one of the most emotionally significant events of their professional life. Having a clear plan for what comes next — the next business, a board role, retirement, travel — helps sellers stay grounded during the process and avoid the ambivalence that delays decisions at critical moments.

28. The best buyers are looking for a partnership, not just an asset. Strategic acquirers and PE-backed buyers who are paying full prices are buying future cash flows that depend, in part, on the cooperation and knowledge of the seller during transition. Sellers who approach the post-LOI process as adversarial often end up with worse outcomes than those who approach it collaboratively — more price retrading, more restrictive deal terms, and harder negotiations.

29. Not every offer is worth taking. There are businesses I've worked with where the right answer — at the time they engaged me — was not to sell yet. Market conditions, business performance trajectory, or personal timing weren't aligned for a strong outcome. A good advisor will tell you this, even though it means deferring the engagement. The right time to sell is when the combination of business performance, market conditions, and personal readiness is maximized — not just when one of those three is ready.

30. The process reveals what you actually built. Going through a serious M&A process — with a real offering memorandum, serious buyers doing real diligence — is one of the most clarifying experiences a business owner can have. You see your business the way a buyer sees it, often for the first time. That clarity, even for owners who ultimately decide not to sell, is valuable in ways that are hard to quantify.

Working with Sellers Across the Southeast and Mid-Atlantic

The transactions behind these lessons include businesses in Charlotte, Raleigh, Greenville SC, Atlanta, Savannah, Richmond, Fredericksburg, Annapolis, and the broader DC corridor. Every market has its own buyer dynamics, its own industry concentrations, and its own transaction culture — but the fundamentals of what makes a sale succeed or fail are consistent. If you're thinking about a sale in the next one to five years, I'd welcome a conversation about where you are in the process and what preparation looks like for your specific situation.
