For most lower middle market sellers, the M&A process is longer, more complicated and more emotionally draining than they expected going in. The deals that close on good terms usually get there because someone ran a disciplined process from the first meeting, with a clear plan and experience of where things go wrong.
Below are the seven phases of a well-run sale: what happens in each, what tends to go wrong, and what separates the sellers who get the outcome they wanted from the ones who don't. If you own a manufacturer, our guide on how to sell a manufacturing business covers the industry-specific issues: equipment, inventory, environmental review and workforce.
Phase 1: Discovery and Goals
A sale starts with a conversation, well before anyone opens a spreadsheet. Before we run any financial analysis, build a buyer list or draft a document, we spend real time on what the owner wants. What does a good outcome look like to you? What would a bad one look like? Answered honestly, those two questions matter more at this stage than any valuation model.
Owners come in with a wider range of goals than people assume. Some care most about total proceeds. Others care more about what happens to their employees and will take a lower headline price from a buyer who commits to keeping jobs and culture intact. Some want full liquidity and a clean exit; others want to keep a minority stake and share in the next phase of growth under new ownership. And some have hard timing constraints (a health event, a partnership agreement, a tax deadline) that shape the structure and pace of the process as much as the economics do.
How your goals shape the rest of the process
What comes out of discovery affects every later phase. An owner whose priority is employee welfare will be matched against a different set of buyers than one who wants the highest price. An owner who wants a two-year earnout to share in the upside needs a different structure than one who needs all cash at close. Put these goals on the table early and talk through the tradeoffs they imply. It saves a lot of time and heads off the late surprises that kill deals.
Late in a process, deals die more often because the owner realizes the outcome on the table isn't the one they wanted than because of diligence or financing problems.
Setting realistic expectations from the start
Discovery is also when an experienced advisor has the hard conversation about what the market is likely to pay. Owners whose expectations come from informal estimates, comparisons with peers or years of hoping deserve straight feedback, and the purpose of that feedback is to prepare them. A seller who knows the realistic range before going to market negotiates with a clear head and judges offers on their merits. Read our post on how to know when it's the right time to sell your business before that first conversation. It covers the financial, personal and market signals that tell you when your options are widest.
Phase 2: Valuation and Preparation
Once the goals are set, two pieces of work run side by side: building a credible valuation, and getting the business and its records ready for buyer diligence. They overlap heavily. Good preparation turns up the same information a careful valuation needs, so each one feeds the other.
What goes into a credible valuation
Applying a multiple to last year's EBITDA is only the starting point. A realistic valuation also weighs the company's normalized financial performance over three to five years, the direction that performance is heading, multiples from recent deals in the same industry and size range, the specific risks in the business, and the growth story it can credibly tell a buyer. Our guide on the five key drivers of business valuation covers each of these and explains what buyers look at when deciding whether a business earns a premium multiple or a discount.
Normalizing earnings means finding and documenting every legitimate add-back: owner compensation above market, personal expenses run through the business, one-time costs that won't recur under new ownership. Our guide on EBITDA add-backs and what they do to your valuation goes through each category and the documentation you need to defend it in a buyer's diligence.
Preparation usually means pulling together three to five years of clean financial statements; a trailing twelve-month income statement; revenue broken out by customer, product and geography; a management org chart with tenure and compensation; key customer and supplier contracts; any pending legal matters; and a summary of physical assets and real estate. Have this ready before buyers ask for it. It shortens the timeline and tells buyers the company is well run.
Managing working capital before going to market
Many owners overlook working capital. In a typical M&A transaction, buyer and seller negotiate a target level of working capital to be delivered at close, and any difference from that target moves the purchase price dollar for dollar. Managing working capital actively over the twelve to eighteen months before a sale can head off post-close adjustments that eat into your net proceeds. Our guide on how to prepare your financials for a business sale covers all five areas of financial readiness.
Phase 3: The Confidential Information Memorandum
Valuation and preparation tell you what the business is worth. The CIM is how you make that case to the buyers who will evaluate it. It is the main marketing document in a sale and the first real look most buyers get at your company, so it shapes their first impression more than anything else they see.
A good CIM tells the story of how the business was built, why it holds the position it does in its market, and what a new owner could do with it. It puts the financial data in context, lays out the competitive advantages, and makes a clear growth case.
The structure of an effective CIM
A well-structured CIM usually includes an executive summary of the investment case; a company overview with history and milestones; a description of products or services and how they differ from competitors'; a look at the target market and the industry; an operational overview; a section on management and employees; a detailed financial section built on normalized EBITDA; and a growth section that lays out specific paths a buyer could invest behind.
Spend extra time on the growth section. It is where the buyer starts picturing themselves as the owner, and a well-written one turns theoretical upside into an investment thesis the buyer can actually underwrite. It does more than almost any other section to create competition among buyers.
A CIM written like an annual report draws about as much interest as an annual report. The ones that work leave a buyer thinking that passing on the business would be a mistake.
Confidentiality and the blind teaser
Most processes start with a blind teaser, a short anonymous description of the business, before the full CIM goes out. Buyers who want more sign a non-disclosure agreement and then receive the CIM. That order protects confidentiality. Disclosing too early can damage relationships with customers and employees, tip off competitors, and unsettle the business right when you need it to be stable.
Phase 4: Buyer Outreach
This is where the preparation meets the actual market. The quality of the buyer list you build, and how tightly you run the process, decide whether you end up with real competition or a take-it-or-leave-it negotiation with one interested party.
Mapping the buyer universe
Buyers fall into two broad groups: strategic and financial. Strategic buyers (often competitors, customers, suppliers or adjacent businesses) can often pay the most because they capture synergies a purely financial buyer can't. Private equity firms buy businesses as investments and aim to improve performance over a three-to-seven year hold period. For sellers who want to keep an equity stake and share in a later sale at a higher valuation, the "second bite of the apple," PE buyers can be the most attractive option there is. Our guide on private equity in the lower middle market covers how PE buyers think and structure deals, and how to tell a good PE partner from one that will cause problems after close.
Competitive tension comes from managing the timing. When several buyers get the CIM at the same time, face the same deadline for indications of interest, and know they are competing with each other, the seller comes out ahead. Buyers move faster, and offers that would have been conservative get sharper. Sold through a well-run competitive process, the same business will routinely fetch a materially different result than it would in a one-on-one negotiation. That is also why we test an unsolicited offer against a competitive process instead of negotiating it in isolation.
Management presentations and site visits
Buyers who get past the first round usually attend management presentations, formal meetings where the leadership team presents the company to them directly. These meetings are as much about chemistry and trust as about information. Prepare hard for them; the hours are worth it. The questions are predictable. Buyers probe customer relationships, competitive differentiation, key-person risk, growth assumptions and why the owner is selling.
Phase 5: Offers and Letters of Intent
When offers come in, most sellers look straight at the headline price. That's understandable, and partly right. In lower middle market M&A, though, the price in a letter of intent is rarely the last word on the economics. The terms in an LOI often matter as much as the number at the top of the page.
What an LOI actually contains
A letter of intent is a non-binding statement that a buyer intends to acquire the business, subject to due diligence and a definitive purchase agreement. Besides price, a well-drafted LOI covers the form of consideration (cash at close, seller financing or earnout), the working capital target and adjustment mechanism, any escrow or holdback, the length of the exclusivity period, and any closing conditions that could give the buyer grounds to renegotiate. Every one of these is negotiable, and a buyer can use any of them to cut the effective price after signing. Our post on 5 LOI gotcha clauses that can hurt sellers during exclusivity goes through the five most expensive provisions and what to insist on before you grant exclusivity.
Look for the buyer you expect to stand behind the deal they proposed once diligence gets difficult. A high price gets a buyer to the table, and getting to closing takes trust on both sides.
Evaluating buyers beyond the economics
If you care what happens to your employees, customers and legacy, the buyer's identity and character matter as much as the price. A private equity firm known for aggressive cost-cutting after close is a different partner from one known for investing in growth. A strategic acquirer that plans to integrate the business within six months means a very different future for employees than one that will run it as an independent subsidiary. Our guide on finding the right buyer for your business covers how to judge buyers on financial, strategic and cultural fit, and why the highest offer isn't always the best one.
Phase 6: Due Diligence
Diligence is where deals either close or fall apart. Once the LOI is signed and exclusivity granted, the buyer's team goes through the financials, legal documents, customer contracts, employee records, intellectual property and anything else material to their decision. The seller's job is to keep that work moving while protecting the economics already agreed.
What buyers are actually looking for
Buyers use diligence to test the investment thesis they formed when they made their offer, and their conviction either holds up or wears away. Financial diligence tests whether the normalized EBITDA in the CIM is real, recurring and defensible. Operational diligence tests whether the business can run without the founder. Legal diligence turns up liabilities, obligations or open questions that could affect the value of the business or whether it can be transferred.
Sellers who commission a sell-side quality of earnings analysis before going to market hand the buyer's team a normalized EBITDA figure they can verify instead of challenge. In our experience those sellers get through diligence faster and see fewer price adjustments after the LOI. Our guide on the quality of earnings report and why every seller should prepare for one explains what a QoE covers, what it costs, and why it almost always pays for itself in deal certainty and price protection.
How to manage diligence without losing momentum
The most common cause of deal collapse is slow erosion. Diligence drags on without resolution, and the buyer's momentum and trust wear down. A single fatal discovery is rarer. Sellers who organize the data room in advance, answer requests quickly and handle questions openly keep the buyer committed. Sellers who are disorganized, slow or evasive invite the skepticism and renegotiation they want to avoid.
A well-organized data room repays the effort more than almost anything else you can do for diligence. Before the first request arrives, it should hold every document the buyer's team is likely to ask for, sorted by category, clearly labeled and complete. Sellers who build it during preparation, instead of scrambling to assemble it under diligence pressure, generally get through diligence faster and with less stress.
Phase 7: Closing and Transition
Once diligence is done and both sides confirm they want to proceed, the last phase begins: drafting, negotiating and signing the definitive purchase agreement, satisfying the closing conditions, and handing over the business. In most lower middle market deals this takes four to eight weeks from the end of diligence to the closing wire.
The purchase agreement
The purchase agreement is the binding legal document for the whole transaction. It turns the LOI terms into obligations, fills in what the LOI left open, and sets out how disputes after close get resolved. The main provisions cover the exact purchase price and any post-close adjustments; the representations and warranties each side makes about itself and the business; the indemnification that applies if a representation turns out to be false; the scope and length of any non-compete and non-solicitation; and the terms of any transition services or employment arrangement for the seller.
Closing conditions and the final stretch
Most purchase agreements make closing conditional on a list of items: regulatory approvals, if required; third-party consents on key contracts; the seller's representations still being true on the closing date; and no material adverse change in the business between signing and closing. Track these closely and raise any that may need extra time or negotiation early. Otherwise you get last-minute delays that wear on everyone's patience.
Transition planning: the phase that sellers underestimate
For many sellers, the months after closing are the hardest part emotionally. The structure that defined your working life for years is suddenly gone, and someone else now manages the relationships you built with employees, customers and vendors. A buyer who needs three to six months of your active involvement to keep things running smoothly is asking for something real. Plan for that period, both operationally and personally, as part of the sale.
The sellers who handle this best went into the process with a clear picture of life after close, personally, financially and professionally, and planned the transition as carefully as they planned the deal. For most of them the deal is really over when the transition is complete and the new owner is running the business confidently on their own.
