This guide follows the sell-side timeline in sequence — from 18 months before a planned sale through closing. Each section covers what you should be doing, what buyers are evaluating at that stage, and the mistakes that most commonly cost sellers time and money. Read it in order the first time. Use it as a reference as your process unfolds.
A note on timing: The stages in this guide are approximations. A well-run lower middle market sale process — from engagement to close — typically takes 5–8 months once preparation is complete. The 18-month and 12-month stages refer to pre-engagement preparation, not the active process itself. Owners who compress this preparation consistently achieve worse outcomes than those who do the work ahead of time.
Most guides about selling a business are written from the perspective of someone who wants to reassure you. This one is written from the perspective of someone who has sat on the other side of the table — evaluating businesses for acquisition at Intel — and has spent years advising owners on how to prepare for exactly that scrutiny. The goal is not to make you feel good about your business. It's to make sure buyers feel good about your business.
When a private equity firm or strategic acquirer evaluates a lower middle market business, they are not reading your materials at face value. They are running a structured process designed to answer one question: Is this business worth what the seller thinks it's worth — and will it continue to perform after a change of ownership?
Every document you provide, every management conversation you have, every number in your financial model is being evaluated against that question. Buyers are not passive. They are professional, well-resourced, and they do this every day. You are doing it once.
What it is: A practical, sequential guide to preparing for and executing a lower middle market sale process. Each stage covers what you should be doing, what buyers are evaluating, and the specific mistakes that cost sellers money at that stage.
What it isn't: A guarantee of any particular outcome, a substitute for qualified legal or financial counsel, or a document you should share with prospective buyers. This guide is for your planning — not for your data room.
Eighteen months is not an arbitrary number. It's the minimum runway required to meaningfully address the issues that most commonly reduce valuations in lower middle market transactions — customer concentration, owner dependency, financial documentation gaps, and legal structural issues. None of these can be fixed in 90 days under deal pressure. All of them can be addressed with 18 months of deliberate work.
Not from a broker trying to win a listing. An honest assessment of what your business would trade for today — and why. Understand the EBITDA a buyer will accept, not just the one you calculate. The gap between those two numbers is what drives preparation decisions.
Document every add-back: owner compensation above market rate, personal expenses run through the business, non-recurring items, one-time costs. Each adjustment needs supporting documentation. Start building this now — buyers will ask for source materials on every line.
If any single customer represents more than 15% of revenue, you have a concentration issue that buyers will discount. Two to three years of deliberate diversification is the only real fix. Start now. Document your diversification progress annually.
Engage qualified counsel to review corporate structure, confirm IP is held by the entity (not personally), identify anti-assignment provisions in key contracts, and verify licenses are current and entity-held. Issues resolved now cost a fraction of what they cost mid-diligence.
Tax-basis financials are not diligence-ready. Buyers expect GAAP-basis statements, ideally CPA-reviewed or audited, for at least three trailing fiscal years. If you're on cash basis, begin the conversion now. This takes time to do correctly.
If you were unreachable for 90 consecutive days, what would happen to your business? Buyers are asking this question. Your answer tells them everything about transition risk — and transition risk drives earnouts, equity rollover requirements, and multiple compression.
Twelve months out is when the preparation becomes concrete. By this point, the foundation work is underway — financials are being cleaned up, legal issues are being addressed, concentration is being reduced. Now the focus shifts to the materials, the team, and the process that will represent your business to buyers.
The advisor's most valuable work happens before the process starts: refining the valuation, shaping the narrative, identifying the right buyer universe, and preparing materials. Advisors engaged 12 months out produce materially better outcomes than those engaged 60 days before a planned go-to-market date.
The CIM is the primary marketing document buyers use to evaluate your business and build their offer. It covers business overview, financial history, growth story, competitive position, and management team. A weak CIM signals an unprepared seller. A strong CIM frames the narrative before buyers can impose their own.
Identify who on your team can present the business to a buyer with confidence. Define their roles clearly. Begin transitioning key customer relationships where possible. Coach them on the business's competitive position, financial model, and growth story. Buyers will meet with your team — twice, in increasing depth. How your team performs in those meetings directly affects offer terms.
Anything that lives only in the owner's head is a liability in a sale process. Standard operating procedures, pricing models, customer onboarding processes, technical documentation, vendor relationships — document them. Not because buyers will read every page, but because documented processes demonstrate that the business runs on systems, not on a person.
Working capital is negotiated at LOI — before formal diligence, when buyers have maximum information advantage. Calculate your trailing 12-month average now. Understand which items buyers will include or exclude in the working capital definition. Arriving at the LOI table with your own analysis is the difference between anchoring and accepting.
A data room is the organized repository of documents buyers access during diligence: three years of financials, tax returns, customer contracts, employment agreements, IP documentation, corporate records, licenses, insurance certificates. Building it over 12 months is professional. Scrambling to build it during an active process is a red flag.
On the CIM: PE firms and strategic acquirers receive dozens of opportunity packages per month. The quality of your CIM tells them immediately whether the seller advisor is professional. A well-structured CIM with clean financials, a compelling growth narrative, and specific, defensible claims about competitive position gets read carefully. A poorly organized one with inconsistent numbers and vague language gets passed over — or repriced to reflect the uncertainty it signals.
This is when the active process begins. Your materials are ready, your advisor is engaged, your data room is populated. The next 60–90 days involve controlled outreach to a qualified buyer universe — generating interest, executing NDAs, distributing the CIM, and running initial buyer conversations in parallel. The goal at this stage is competitive tension. One interested buyer is a negotiation. Three interested buyers is a process.
Confidentiality failures are among the most damaging events in a sale process. Employees who learn of a pending sale before the owner is ready to disclose may leave. Customers may become uncertain. Competitors may use the information strategically. A well-run process controls information tightly: NDAs before materials, materials through a controlled data room, no identifying information in teasers, and a disclosure plan ready for employees and customers before closing.
When to tell employees: typically at or very near closing, once deal terms are final and the transition plan is in place. Earlier disclosure serves the buyer's interests, not yours.
The Letter of Intent is non-binding on price — but signing it begins the exclusivity period and creates significant deal momentum. Changes after signing are possible but create friction and can damage buyer relationships. Everything in the LOI is negotiable before you sign it. Much less is negotiable after. Treat the LOI negotiation with the same rigor you would the final purchase agreement.
| Term | What It Means | Seller-Favorable | Watch For |
|---|---|---|---|
| Purchase Price & Structure | Total enterprise value and how it's split between cash at closing, earnout, and equity rollover | 80%+ cash at close; minimal deferred consideration | Large earnout or equity rollover without governance rights |
| Working Capital Target | The level of working capital that must be in the business at closing; shortfall reduces the price dollar-for-dollar | Trailing 12-month average; seller-defined methodology | Target set above historical average; buyer's accountant as arbiter |
| Earnout Structure | Deferred consideration contingent on post-close performance | Revenue-based metric; 12-month duration; low threshold; buyer covenants to fund operations | EBITDA metric buyer controls; 3-year duration; targets above historical performance |
| Exclusivity Period | Period during which you cannot negotiate with other buyers | 45–60 days; defined milestones; automatic termination if buyer fails to perform | 90+ days with no milestones; no termination mechanism |
| Escrow / Holdback | Portion of proceeds held post-close against indemnification claims | 8–10%; 12–18 months; claims basket at 0.75%+ of purchase price | 15%+; 24 months; first-dollar indemnification; broad definition of covered claims |
| Conditions to Closing | Requirements that must be met before the deal closes | Narrow, specific, achievable within the diligence timeline | Broad MAC provisions; third-party consent conditions with no timeline |
Appropriate: The business has signed contracts not yet generating revenue, or near-term growth events (product launch, new market entry) that the historical financials don't yet reflect. The earnout bridges the gap between what history shows and what the near-term trajectory supports.
Not appropriate: The buyer is using the earnout to avoid underwriting earnings they could verify from the historical record. If a buyer proposes a large earnout for a business with 5 years of consistent, documented EBITDA, they are not bridging a valuation gap — they are shifting risk to you for a business they can underwrite. Recognize the difference before accepting.
Due diligence is not a box-checking exercise. It is a structured process designed to either confirm a buyer's offer thesis or surface reasons to reprice, retrade, or walk. Issues discovered in diligence are almost always used as leverage — because the seller is now exclusively committed and the buyer knows it. The goal of preparation is to ensure that what buyers find in diligence matches what you've told them. Surprises in diligence go in one direction only.
A QofE report is prepared by the buyer's accounting firm to independently reconstruct and verify your EBITDA. They will test every add-back, review revenue recognition, assess working capital trends, and identify any financial presentation issues. A seller-prepared QofE (commissioned before the process) dramatically accelerates diligence and removes the buyer's ability to use financial uncertainty as a repricing lever.
Buyers' counsel reviews corporate structure, IP ownership, material contracts (especially for anti-assignment and change-of-control provisions), litigation history, employment agreements, licenses and permits, and any pending regulatory matters. Issues here — particularly IP held outside the entity or contracts requiring consent — become closing conditions that shift timeline leverage to the buyer.
Buyers assess whether the business can perform post-close without the current owner. Management team evaluation, customer relationship mapping, technology and systems review, vendor concentration analysis, and key employee retention risk. This workstream is where management presentations matter most — buyers are building their post-close operational thesis from what they observe.
PE buyers in particular will validate the market thesis: How large is the addressable market? Is it growing or contracting? What is the competitive landscape? How defensible is the company's position? For IT services, SaaS, and health tech businesses, buyers often commission independent market analysis. The claims in your CIM will be tested.
Diligence takes 60–90 days in the lower middle market. During that time, you are simultaneously running your business and responding to a constant stream of buyer requests. This is where owner bandwidth becomes a real constraint. Assign a dedicated internal point of contact for diligence requests — ideally your CFO or COO. Build the data room completely before diligence starts. Anticipate repeat-request categories (additional periods, alternative cuts of financial data, HR records) and pre-populate them. A disorganized diligence process signals a disorganized business.
Diligence is complete. The buyer's position is confirmed. The final 30–60 days are consumed by purchase agreement negotiation, regulatory and third-party consents, closing condition satisfaction, and transition planning. This stage feels like the finish line — and it is. But deals have failed in the final 30 days more often than owners expect, almost always due to issues that should have been identified and resolved earlier. Finish strong.
The purchase agreement is the definitive legal document governing the transaction. It expands on the LOI terms in full legal detail: representations and warranties, indemnification scope and caps, closing conditions, post-close covenants, and transition obligations. This document requires experienced M&A transaction counsel — not a generalist business attorney. The specific language in representations and warranties, survival periods, and indemnification baskets has material economic consequences.
Key negotiation points at this stage: narrowing the scope of seller representations (knowledge qualifiers, materiality thresholds), limiting survival periods for general reps, reducing the indemnification basket, and — where the seller's legal profile supports it — exploring rep and warranty insurance to replace or reduce the escrow holdback obligation.
Confirm all conditions in the LOI and purchase agreement are met: third-party consents obtained, regulatory approvals received, financing confirmed, material contracts assigned. Unresolved conditions at closing are leverage for buyers to seek price adjustments or delay.
Prepare a clear, honest communication for employees — timed for as close to closing as confidentiality allows. The message should address who the new owner is, what is and isn't changing, and what it means for the team. First impressions from the acquirer matter to employee retention.
Define what the seller's post-close obligations are, the duration and terms of any consulting arrangement, and how knowledge transfer will be structured. Agree on customer communication messaging. Ensure the new owner is introduced to key relationships in a managed, confidence-inspiring way.
Review the closing statement carefully: enterprise value, debt payoffs, working capital adjustment, escrow amounts, transaction fees, and net proceeds to seller. This document should have no surprises — any adjustments should have been agreed in advance. Verify the wire instructions and confirm the timeline for escrow release.
The structure of the transaction — asset sale vs. stock sale, allocation of purchase price, installment sale treatment for earnouts — has significant tax implications. These decisions need to be made before closing, not after. A qualified CPA with M&A transaction experience should be involved well before the closing date.
Selling a lower middle market business is the most consequential financial transaction most owners will ever execute. It rewards preparation more than any other factor — more than timing, more than market conditions, more than negotiating skill. The owners who achieve the best outcomes are not necessarily the ones with the best businesses. They are the ones who understood the process, did the work ahead of time, and showed up to every buyer conversation as the most prepared party in the room.
That is what this playbook is designed to help you do.
A free 30-minute strategy call with Dave Halvorson covers what your business would realistically look like in a transaction today, what's worth addressing before you engage buyers, and what a realistic preparation timeline looks like for your situation.
