Selling a business is not like selling a house. The comparison gets made often because it’s the closest analogy most people have for a large private transaction — and in some ways it’s useful. There is a seller, a buyer, a price, a closing. But the resemblance largely ends there.

A house sale takes weeks. A business sale takes months — typically six to twelve months from the engagement of an advisor to the closing of a transaction, and often longer when preparation work is included in the timeline. A house sale is largely public; anyone can see the listing, the price, and the eventual sale. A business sale is almost entirely confidential, for reasons that directly affect the value of the asset being sold. A house sale has a relatively predictable structure. A business sale involves legal, tax, financial, and operational complexity that requires a team of advisors working in coordination.

Owners who understand how the process actually works navigate it better. Uncertainty and surprise are the enemies of good outcomes in a transaction. This guide walks through each phase of a business sale from beginning to end.

Phase 1: Preparation (Months 1–2)

Before any buyer is contacted, before any document is prepared, before any conversation about a sale begins — there is preparation. This phase is often invisible to the outside world and is sometimes underestimated by owners who are eager to get to the market, but it sets the conditions for everything that follows.

Assembling the advisory team. A mid-market business sale requires three professional advisors at minimum: an M&A advisor (the deal quarterback who manages the process from beginning to end), an accountant with deal experience (who advises on tax structuring, financial due diligence defence, and closing mechanics), and a transaction lawyer (who drafts and negotiates the purchase agreement and manages the legal aspects of closing). The quality and coordination of this team has an enormous impact on both the price achieved and the probability that the transaction closes at all. Owners who go into a sale without experienced deal counsel on each of these fronts routinely leave money on the table or encounter problems that could have been anticipated.

Valuation and pricing strategy. Before going to market, your advisor will develop a valuation range for the business — a realistic assessment of what the business is worth and what asking price is appropriate. This is not the same as a formal CBV valuation; it is an advisory opinion informed by comparable transactions, normalized financials, and the advisor’s knowledge of the current buyer market. The pricing strategy needs to be calibrated carefully: too high and you waste time with unserious buyers; too low and you leave money behind. The goal is a price that attracts qualified buyers while reflecting the genuine value of what you’ve built.

Confidential Information Memorandum (CIM). The CIM — also called a management presentation or information memorandum — is the document that tells the story of your business to qualified buyers. A well-crafted CIM covers the business overview, financial performance (three to five years of historical results plus forward-looking context), market position, operational details, management team, and the investment thesis — why this business represents an attractive acquisition. It is the buyer’s primary information source before they request a management meeting. It needs to be accurate, comprehensive, and compelling.

Data room setup. The data room is the organized repository of documents that buyers will access during due diligence. Setting it up before you go to market — rather than scrambling to assemble it while buyers are waiting — is a significant process advantage. Virtual data rooms (secure online platforms) are standard in mid-market transactions. Having the key documents organized, indexed, and uploaded before the first buyer receives a CIM positions you as organized, professional, and prepared.

Phase 2: Going to Market (Months 2–4)

Going to market means, in practical terms, that qualified potential buyers are being identified and approached. This phase is managed with confidentiality as the primary constraint. The goal is to find the right buyers without revealing to the world — your employees, your customers, your competitors — that the business is for sale.

Identifying potential buyers. Your M&A advisor will develop a buyer list based on an analysis of who is most likely to have strategic interest in your business and the financial capacity to complete the acquisition. The list typically includes strategic buyers (competitors, adjacent companies, consolidation plays in your sector), financial buyers (private equity groups and family offices active in the mid-market), and sometimes management buyout candidates. Developing a thoughtful buyer list is one of the most valuable things an advisor does; a lazy or incomplete list means missed opportunities.

Teaser documents and NDAs. Initial outreach to potential buyers uses a “blind teaser” — a one- to two-page document that describes the business and its financials in general terms without identifying it. Interested parties execute a non-disclosure agreement before receiving the full CIM. The NDA creates a legal obligation of confidentiality before sensitive information is shared, protecting you throughout the marketing process.

Managing inbound interest. As the process progresses, some buyers will be more serious than others. Part of your advisor’s job is to manage the pipeline — keeping serious buyers engaged, providing information efficiently, and filtering out parties who lack the financial capacity or genuine strategic interest to complete a transaction. A well-managed process keeps multiple credible buyers engaged simultaneously, which creates the competitive dynamics that support pricing and deal terms.

Phase 3: Buyer Qualification and the Letter of Intent (Months 4–6)

Once the field of interested buyers has been narrowed through the information-sharing and management meeting process, the most serious candidates are asked to submit offers or indications of interest. This leads to the letter of intent — the document that, when signed, marks a major milestone in the transaction.

How serious buyers are vetted. Before significant time is invested in any buyer, your advisor should verify their financial capacity to complete the acquisition, understand their strategic rationale, and assess whether their timeline and approach are realistic. A buyer who expresses interest but can’t demonstrate access to funding is a distraction. A buyer whose stated acquisition criteria don’t actually match your business profile is unlikely to close. Qualifying buyers early saves time and protects confidentiality.

The Letter of Intent (LOI). The LOI — sometimes called a term sheet or offer to purchase — is a document that sets out the buyer’s proposed terms for the transaction. It is typically non-binding on price and structure but binding on confidentiality and the exclusivity period that follows. A well-constructed LOI covers: the proposed purchase price and payment structure (cash at close, vendor take-back, earnout, etc.), the scope of what is being acquired (shares or assets), key conditions to closing, the target timeline, and the exclusivity period during which the seller agrees not to negotiate with other parties.

The LOI negotiation is consequential. Terms agreed at LOI become the basis for the purchase agreement. An LOI that is accepted without careful review often produces a closing document that is much less favourable than the seller expected. Your lawyer and advisor should review any LOI carefully before you sign it.

Exclusivity. Most buyers will require a period of exclusivity — typically 45 to 90 days — during which you agree not to negotiate with other potential buyers while they complete due diligence. This is standard and reasonable; buyers won’t invest the time and money in a thorough due diligence process without protection against being outbid at the end of it. The risk for the seller is that exclusivity hands the buyer significant leverage. If due diligence reveals issues, the buyer can use them to renegotiate — and you have no alternative offer to fall back on. This is why maintaining multiple credible buyers in the process for as long as possible strengthens your position.

Phase 4: Due Diligence (Months 6–9)

Due diligence is the phase where the buyer verifies that the business is what it appears to be. It is thorough, time-consuming, and often stressful for sellers. It is also where most deals die — not because businesses are misrepresented, but because things are discovered that weren’t expected, raising questions that can’t be answered cleanly or quickly enough to keep the buyer’s confidence intact.

The scope of due diligence in a mid-market transaction typically includes:

• Financial DD: Verification of historical financial performance, quality of earnings analysis, working capital assessment, review of accounting policies and their consistent application
• Legal DD: Review of all material contracts, corporate structure verification, litigation history, employment agreements, regulatory compliance
• Operational DD: Assessment of processes, systems, facilities, equipment condition, management team quality
• Tax DD: Review of tax compliance, structuring analysis, identification of any exposure
• Environmental DD: Particularly for manufacturing and industrial businesses — Phase I/II assessments, regulatory permit review

Your role as seller during this phase is to be responsive, organized, and transparent — not defensive. A seller who answers every question promptly, who has anticipated the likely requests and prepared for them, and who provides context rather than just documents, moves through due diligence faster and with less friction. A seller who is slow to respond, who produces incomplete documentation, or who appears to be managing information rather than sharing it creates friction that can become fatal to the deal.

Phase 5: Negotiation and Closing (Months 9–12)

Due diligence leads into the purchase agreement — the definitive legal document that governs the transaction. This is the most legally complex phase of the process and the one where experienced transaction counsel is most important.

The purchase agreement covers, among many things: the purchase price and payment structure, working capital adjustments, possible earnout provisions, representations and warranties (the seller’s formal statements about the condition of the business), indemnification provisions (what happens if those statements turn out to be wrong), restrictive covenants (non-compete and non-solicitation obligations), the transition period arrangement, and the specific mechanics of closing.

Working capital adjustments are one of the most commonly misunderstood closing mechanics. The standard is that the seller delivers the business with a “normal” level of working capital — receivables, inventory, and payables at levels consistent with historical operations. If the actual working capital at closing differs from the target, the purchase price is adjusted accordingly. Sellers who deplete receivables or drain inventory in the weeks before closing to improve their personal cash position typically find that the working capital adjustment claws it back dollar for dollar.

The transition period is the arrangement, agreed at closing, under which the seller remains available to support the buyer’s orientation and the handover of relationships, knowledge, and operations. The duration and intensity of transition arrangements vary widely: some sellers are available for thirty days of consulting; others agree to two years of part-time engagement. The terms should be negotiated explicitly rather than left vague — ambiguity about what the seller owes post-close generates disputes.

The closing day itself is often anticlimactic — a series of document signings and wire transfers coordinated by lawyers. The emotional weight of the transaction is front-loaded, in the decision to sell and in the negotiation. By closing day, most of the work is done.

Understanding the Process Gives You an Advantage

Owners who understand the structure of the sale process enter it with two advantages. First, they can participate as informed principals rather than relying entirely on their advisors to interpret what’s happening and why. Second, they have realistic expectations — about the timeline, about the intensity of due diligence, about the post-signing commitments that will be expected of them. Realistic expectations prevent the kind of anxiety-driven decisions that derail transactions at inconvenient moments.

The process is demanding. It takes longer than most owners expect and requires more from them than selling most assets they’ve ever sold. But it is navigable — and for owners who have prepared well, who have a strong advisory team, and who understand what’s coming, it produces outcomes that reflect the genuine value of what they’ve built.
