TL;DR

A sell-side process is eight phases, six to twelve months, and one narrow window where your leverage is at its peak.

  • Preparation is the longest lever and the only phase entirely under your control
  • Leverage peaks the day before you sign the letter of intent and falls sharply the day after
  • Diligence is where deals die, usually over something the seller already knew about
  • Whatever is left vague in the letter of intent gets settled later, when only one buyer is still at the table
  • The business still has to perform throughout, and buyers watch every month of it

The Typical Phases of a Sell-Side Process

While every transaction has its own wrinkles, most lower middle market sell-side processes follow a similar sequence. Here is what each phase involves.

  1. Preparation & Positioning. Before any buyer is contacted, the advisor and owner organize financial statements, normalize earnings (often adjusting EBITDA for one-time or owner-specific expenses), and identify the story of the business, including its growth drivers, customer base, and competitive position. This phase also includes early conversations about the owner's goals for a sale, from timeline to post-closing involvement.
  2. Marketing Materials & Buyer List. The advisor prepares a confidential information memorandum (or similar marketing package) describing the business, along with a shorter teaser document that does not reveal the company's identity. In parallel, the advisor and owner build a target list of potential strategic buyers and private equity firms likely to have interest.
  3. Confidential Outreach. The advisor contacts prospective buyers, starting with a teaser and, once a non-disclosure agreement is signed, sharing the fuller memorandum. Confidentiality is a priority throughout this phase so that employees, customers, and competitors do not learn of a potential sale prematurely.
  4. Indications of Interest (IOIs). Interested buyers submit a preliminary, non-binding indication of interest outlining a proposed valuation range, deal structure, and other high-level terms. This step helps narrow the buyer pool to those with realistic and credible offers.
  5. Management Meetings. Buyers who advance meet with company leadership, often in person, to ask detailed questions about operations, customers, and growth plans. These meetings frequently shape a buyer's final offer and give the owner a chance to evaluate cultural fit.
  6. Letters of Intent (LOIs). One or more buyers submit a more detailed, though still largely non-binding, letter of intent. The owner and advisor negotiate and select a preferred buyer at this stage, sometimes after a further round of back-and-forth on price and terms.
  7. Due Diligence. Once an LOI is signed, the buyer conducts a thorough review of the business, covering financials, contracts, legal matters, customer concentration, employee matters, and often a quality of earnings (QoE) analysis performed by an accounting firm. This is the most document-intensive phase of the process.
  8. Purchase Agreement & Closing. Legal counsel for both sides negotiate the definitive purchase agreement, covering representations, warranties, indemnification, and other binding terms. Once signed, the transaction closes and ownership transfers, often followed by a transition period for the outgoing owner.

Why a Structured, Competitive Process Matters

Some owners are approached directly by a single interested buyer and consider negotiating one-on-one rather than running a broader process. A structured, competitive process, where multiple qualified buyers evaluate the opportunity at the same time, gives an owner more information and more leverage than a single-buyer negotiation. When only one buyer is at the table, that buyer has less incentive to offer their best price or terms, since there is no competing bid to respond to.

Running a process with several buyers simultaneously also tends to surface a wider range of deal structures, from an all-cash sale to structures involving rollover equity or earnouts. A broader process takes more coordination and time, and it isn't the right fit for every owner. The right choice depends on the specific business and what the owner wants out of the sale.

Phase What Happens Typical Duration Where Your Leverage Sits
Preparation & Positioning Organize financials, normalize earnings, define the story 4–12 weeks Total control; nothing is committed yet
Marketing Materials & Buyer List Build the memorandum, teaser, and target buyer list 2–4 weeks High; the buyer list shapes everything downstream
Confidential Outreach Contact buyers under NDA 3–6 weeks High; you can add buyers, not subtract information
Indications of Interest Buyers submit preliminary, non-binding terms 2–4 weeks Rising as bids arrive
Management Meetings Buyers meet leadership and ask detailed questions 2–4 weeks Peak, if several buyers are still live
Letters of Intent Decision Point Buyers submit more detailed terms; a preferred buyer is chosen 2–3 weeks Maximum before signing, sharply lower after
Due Diligence Buyer reviews financials, contracts, legal, and quality of earnings 6–12 weeks Low; you are usually under exclusivity
Purchase Agreement & Closing Legal counsel finalizes binding terms; transaction closes 4–8 weeks, often overlapping diligence Limited, and mostly a function of your willingness to walk

What a Competitive Process Actually Produces

The argument for running a structured process rather than negotiating with one interested party is measurable. In the IBBA and M&A Source Market Pulse survey of completed transactions up to $50 million, 83% of deals above $5 million attracted at least three offers, and 18% attracted ten or more (IBBA / M&A Source Market Pulse). Multiple bidders is the normal outcome of a real process, not an exceptional one.

The same data shows why the buyer list matters as much as the materials. In the lower middle market, 35% of buyers were strategic acquirers, 19% private equity firms, and 24% first-time buyers. Those groups read a business differently and move at different speeds, so a process aimed at only one of them leaves most of the field untouched. Our guide on strategic versus private equity buyers covers how each one prices a deal.

The Letter of Intent Is the Real Negotiation

Owners tend to treat the letter of intent as a milestone and the purchase agreement as the negotiation. It is the other way around. Signing a letter of intent almost always means granting exclusivity, and exclusivity means every other buyer goes away. From that moment the leverage that produced your price no longer exists, and any term left unresolved gets resolved with one counterparty who knows you have no alternative.

Which is why the terms below belong in the letter of intent, in writing, before you sign:

  • Price, and what it is composed of. Cash at closing, escrow, earnout, seller note, and rollover stated separately as dollar amounts rather than folded into one headline number.
  • The working capital target and how it is calculated. This is the most common source of a late price reduction, and it is far easier to negotiate the methodology now than the outcome later.
  • Escrow size and survival period. How much is held back, for how long, and whether representation and warranty insurance is contemplated.
  • Earnout mechanics. The metric, who calculates it, what happens if the buyer changes the business in ways that affect it, and whether unmet targets can be caught up in a later period.
  • Your post-closing role. Duration, compensation, title, and what happens if it ends early.
  • The exclusivity period itself. Sixty to ninety days is common. Ask for it to expire automatically rather than extending on request, and consider tying an extension to the buyer having completed specific workstreams.
  • Financing status. Whether the offer is contingent on financing, and what evidence of committed capital the buyer can produce today.

A buyer who resists specificity at this stage is preserving room to move the terms later. That is not necessarily bad faith; it is a normal negotiating position. Your response is to trade specificity for speed: signal that the buyer prepared to commit to real terms gets exclusivity fastest.

Where Deals Actually Break

Most failed processes fail for one of a small number of reasons, and nearly all of them are visible in advance.

  1. The financials do not survive scrutiny. Add-backs without documentation, revenue recognized in the wrong period, or statements that do not reconcile to tax returns. The fix is a sell-side quality of earnings review or, at minimum, a clean reconciliation done before going to market.
  2. Performance slips mid-process. A process consumes owner attention for months, and buyers see monthly financials the whole time. A soft quarter during diligence invites a price re-trade at exactly the moment you have the least leverage. Protect operating time and delegate deal work to your advisor.
  3. Financing falls through. Especially with individual buyers who need a lender. Qualify financing at the indication of interest stage, not after exclusivity.
  4. Something surfaces in legal diligence. An unassignable contract, an unresolved employment claim, missing corporate records, an environmental question at an owned site. These delay rather than kill deals, but delay costs momentum and momentum is what closes transactions.
  5. The working capital settlement goes badly. The number is agreed late, calculated by the buyer's accountants, and settled after closing. Negotiate the methodology in the letter of intent.
  6. The seller changes their mind. More common than owners expect, and worth confronting early. If you are not certain you want to sell, the middle of diligence is a costly place to discover it, both financially and in relationships with buyers you may want again later.

What a Process Costs, and Who Pays for It

The advisory fee is the visible cost and rarely the only one. Budget for legal counsel on the purchase agreement, accounting support, and, if you commission one, a sell-side quality of earnings review. Most of these are payable regardless of whether the transaction closes, which is a reason to be honest with yourself about readiness before starting.

On advisory fees specifically, published benchmarks exist. The Firmex M&A Fee Guide, produced annually with Axial and Divestopedia, models a sell-side success fee of about 6.3% on a $5 million transaction, 3.9% at $20 million, and 2.0% at $100 million in its 2023–24 US edition; its 2024–25 global edition models 4.8%, 3.4%, and 2.0% at the same sizes. Rates decline as deal size rises, so a quote well outside those bands deserves an explanation. Our guide on how to choose an M&A advisor covers the engagement-letter terms that matter more than the headline percentage.

How the Process Differs by Sector

The arc is the same everywhere; the emphasis is not.

  • Industrials and manufacturing. Expect a longer diligence phase, because site visits, equipment assessments, and environmental review add workstreams that a services business does not have. See our guide to M&A advisors for industrials and manufacturing.
  • Business services. Outreach lists tend to be the longest and most varied, since strategics, sponsors, and individual buyers are all credible. That breadth is what makes the process competitive. See our guide to M&A advisors for business services companies.
  • Early childhood education. A short, well-defined buyer list and heavy regulatory diligence around licensing, ratios, and facilities. Real estate is often negotiated as a parallel transaction. See our guide to M&A advisors for early childhood education.
  • Consolidating sectors. Experienced acquirers move faster and arrive with standard documents and standard terms, which is efficient but leaves less room to negotiate structure. Our piece on roll-ups in legal services and pet care covers what to expect.

Roles Involved in the Process

A sell-side process involves several parties working together, each with a distinct role:

  • Owner/founder. Provides information about the business, makes key decisions on offers and terms, and ultimately decides whether and when to sell.
  • M&A advisor or investment bank. Coordinates the process end to end, preparing materials, managing buyer outreach, negotiating terms, and keeping the timeline moving.
  • Buyer(s). May be a strategic buyer looking to expand operations or a private equity firm pursuing a financial investment; each brings different priorities to negotiations.
  • Legal counsel. Represents the owner and, separately, the buyer in drafting and negotiating the purchase agreement and related legal documents.
  • Accountants and quality of earnings (QoE) providers. Help normalize financials early in the process and, later, support the buyer's due diligence review.

What to Watch Along the Way

Beyond understanding the phases themselves, a few practical considerations tend to matter throughout a sell-side process:

  • Confidentiality throughout. Maintaining confidentiality until it is appropriate to disclose a potential sale generally protects relationships with employees, customers, and competitors.
  • Keeping the business performing. A process can run for several months, and buyers pay close attention to how the business performs during that window. Steady performance supports the deal.
  • Being ready for diligence requests. Due diligence generates a large volume of document and information requests; having records organized in advance can help the process move more smoothly.
  • Managing employee communication timing. Deciding when and how to inform employees is a sensitive judgment call, and the right timing generally depends on the specific deal and company culture.

Where Salt Creek Advisory May Fit

Salt Creek Advisory runs sell-side M&A processes for lower middle market business owners, aiming to structure a competitive process with multiple qualified buyers rather than a single negotiation. Both principals typically stay involved in engagements directly, from preparation through closing. For an owner trying to understand what a process like this would look like for their own business, that may be worth a conversation. How each phase actually plays out varies by business, and no advisor can promise a specific outcome in advance.

Know the Phases Before You Start

The lower middle market M&A process follows a fairly consistent arc (preparation, marketing, buyer engagement, negotiation, diligence, and closing), even though the specifics vary from deal to deal. Know these phases going in, and you can set realistic expectations, ask sharper questions of any advisor you consider, and avoid being caught off guard by what each stage demands.
