Sell-Side M&A Process:
A Guide for Lower Middle Market Business Owners

What the Sell-Side M&A Process Is and How Long It Takes

The sell-side M&A process is a structured effort to prepare your company, approach qualified buyers confidentially, compare offers, negotiate terms, complete due diligence, and close a sale. A typical lower-middle-market transaction takes about six to nine months, though complex diligence, financing, or legal issues can extend the schedule beyond a year.

Your advisor prepares the company for buyers before outreach begins. Your advisor reviews financial records, calculates adjusted EBITDA, and develops marketing materials. Adjusted EBITDA measures normalized operating earnings before interest, taxes, depreciation, and amortization, with documented adjustments for defensible owner-specific or one-time expenses.

Your advisor then contacts qualified buyers confidentially and manages the offer process. Interested buyers submit initial indications of interest, and selected buyers meet management before presenting letters of intent. After you sign a letter of intent, the chosen buyer conducts financial, legal, tax, and operational diligence. Both sides then negotiate the purchase agreement and closing terms.

Your company’s readiness and record quality affect the early schedule, while buyer response and deal structure affect the time required to negotiate and close.

This guide addresses owners of established private companies with roughly $2 million to $75 million in annual revenue and generally at least $500,000 of adjusted EBITDA. It applies to founders and families considering a sale soon, evaluating an unsolicited offer, or preparing several years in advance.

1. Preparing to Sell

Preparing to sell requires you to identify issues that could affect valuation, buyer interest, or closing before outreach begins. Review customer concentration, owner dependence, recurring revenue, contracts, forecasts, and unresolved operating matters so your advisor can present them accurately and plan for likely buyer questions.

Financial preparation continues in the detailed record-gathering phase below. In particular, reconcile tax returns with financial statements and document every adjusted EBITDA item with a reasonable business explanation. Buyers may discount unsupported adjustments or change their offers when diligence reveals discrepancies.

2. Selecting an Advisor

Choose an advisor based on who will perform the work, how the buyer process will be managed, and what the full fee structure requires. Ask who will attend buyer calls, negotiate key terms, prepare materials, coordinate diligence, and remain accountable through closing.

Salt Creek’s standard M&A engagements use a success-fee model with no upfront retainer. Our clients work directly with Jack and Connor Pitts throughout the process rather than being handed off to a junior deal team. This model may fit founder-led and family-owned businesses that want direct principal involvement.

3. Organizing Financial Information

Organized financial information supports the valuation presented to buyers and reduces avoidable questions during diligence. Key materials commonly include:

• Tax returns, income statements, and balance sheets
• Monthly financial statements
• Revenue and profitability by customer, service line, or location, where relevant
• Support for adjusted EBITDA and each proposed adjustment
• Major customer, supplier, employment, and other material contracts
• Forecasts and the assumptions behind them

The marketing package explains the company’s performance, operations, and acquisition rationale using facts that buyers can verify. A short teaser describes the business without revealing its identity and allows prospective buyers to decide whether to sign a nondisclosure agreement. After signing, qualified buyers receive a confidential information memorandum. The memorandum explains the company’s operations, market position, and financial performance. It should support forecasts and other growth claims with operating data and documented assumptions.

A secure data room holds the documents behind those claims. You should expect to gather financial statements, major contracts, employment information, and other records that buyers will eventually review. Resolve inconsistencies before outreach so buyers can verify the marketing claims against the underlying records. Consistent figures reduce follow-up questions and give you stronger support if a buyer later challenges the valuation.

Incomplete records can delay marketing because the advisor must resolve discrepancies before presenting financial claims to buyers. Your advisor should test the materials as a buyer would. Your advisor should address unsupported forecasts and any concentration or owner-dependence concerns before buyers begin forming views on value and risk.

Salt Creek Advisory uses internal technology, including AI tools, to help organize company information, conduct initial buyer research, and identify records that require review. Jack and Connor Pitts review the output and remain responsible for interpreting the financial information, positioning the company, and making confidentiality decisions. Technology can reduce manual work, but an advisor still must decide which facts matter and how buyers are likely to interpret them.

4. Building a Buyer List

A sell-side M&A advisor builds the buyer list around fit rather than volume. The advisor evaluates each buyer’s industry focus, transaction size, acquisition history, geography, and ability to finance a deal. You should review the list and exclude competitors or other parties whose involvement could compromise confidentiality.

Each buyer type applies a different acquisition strategy and financing model when evaluating your company. Strategic buyers may see value in your customers, capabilities, or market position. Private equity firms typically evaluate your company as a new platform investment or an addition to an existing portfolio company, and they made about one-fifth of lower-middle-market acquisitions in 2025, according to IBBA and M&A Source Market Pulse data. Family offices may acquire companies using capital managed for one or more wealthy families. Independent sponsors typically identify an acquisition before securing the equity needed to complete it. Individual buyers, including first-time buyers and serial entrepreneurs, made up 44% of lower-middle-market acquisitions in the same period. Your advisor should include them when their experience, financing capacity, and acquisition criteria fit your company.

5. Confidential Outreach

A targeted process approaches selected buyers privately instead of posting the business on a marketplace or distributing materials to an unfiltered list. Salt Creek uses buyer research technology to expand coverage and organize outreach. Jack and Connor Pitts review buyer fit and manage communications. A broader list can create competition, but outreach should remain limited to credible buyers who have a reason to pursue the company.

Confidentiality practices control what each buyer sees and when they see it. Initial outreach uses a blind teaser that describes the business without naming it or revealing identifying details. Interested buyers must sign a nondisclosure agreement before receiving the confidential information memorandum. The advisor can release sensitive records such as customer names and detailed contracts later as buyers demonstrate serious interest.

Buyer outreach and initial screening often take four to eight weeks. During that period, the advisor handles preliminary questions, buyer responses, and nondisclosure agreements. The advisor then identifies buyers prepared to submit an indication of interest. Staged disclosure and controlled data-room access limit sensitive information to buyers who have demonstrated serious interest. Documented communications also create a record of what the advisor shared and when.

6. Indications of Interest

The middle phase usually takes six to ten weeks after buyers receive the confidential information memorandum. Your advisor collects indications of interest and uses them to choose candidates for management meetings and final letter of intent proposals.

An indication of interest, or IOI, gives a buyer’s preliminary valuation and proposed transaction structure. Most IOIs remain nonbinding and rely on assumptions that the buyer has not yet verified. Your advisor should compare each proposal’s total economics and closing conditions rather than ranking buyers by headline price alone.

7. Management Meetings

Management meetings give shortlisted buyers direct access to you and other senior leaders. Buyers use these discussions to assess senior leadership and test the assumptions behind their preliminary valuation and growth forecast. You can also evaluate how each buyer makes decisions and how its plans would affect you and your employees.

8. Letters of Intent

After management meetings, serious buyers submit updated proposals or letters of intent. An LOI records the proposed price and explains how the buyer plans to pay it. A strong LOI also addresses working capital assumptions, treatment of debt and cash, expected diligence, financing conditions, required approvals, and the proposed closing schedule. You should resolve major economic points in the LOI and ask your transaction attorney to review any language that could let the buyer change its offer after diligence.

Exclusivity deserves careful review because it changes your negotiating position. Once you sign an LOI with an exclusivity provision, you generally agree to stop soliciting or negotiating with other buyers for a stated period. The selected buyer can then complete diligence without competition from the other bidders.

Before signing, you should resolve as many material terms as possible while multiple buyers still remain engaged. Your M&A advisor can compare the commercial proposals, while your transaction attorney reviews binding provisions such as exclusivity and confidentiality. A clear LOI cannot eliminate closing risk, but it can reduce disputes over terms that both sides could have addressed earlier.

How a Competitive Process Compares With a Single Unsolicited Offer

In the Q1 2026 Market Pulse survey, 83% of deals over $5 million attracted at least three offers, and 18% attracted ten or more bids. Multiple offers are common in lower-middle-market transactions, although no process can guarantee them.

Credible competing offers can strengthen your negotiating position because you retain alternatives if one buyer changes its terms. A defined bid deadline gives buyers the same submission window and allows your advisor to compare proposals at the same stage of the process. If one buyer later reduces its price or adds a difficult condition, you may still have other parties to call.

Multiple bids also reveal how the market values your company. A strategic buyer may pay for cost savings or access to customers that it can gain through an acquisition. A private equity firm may value the same company based on expected growth and the returns available under its ownership model. One unsolicited offer reflects one buyer’s analysis, not a full market test.

A competitive process also gives you more transaction structures to compare. One buyer may offer more cash at closing, while another proposes rollover equity or an earnout that could increase your eventual proceeds. Buyers may also differ in closing certainty and post-closing plans. Your advisor should compare the economic value and risk of each proposal rather than rank offers by headline price alone.

You may still want to explore an unsolicited offer. Before granting exclusivity, you can test whether other qualified buyers have interest through a controlled and confidential outreach process. A limited market check can provide pricing and terms for comparison while restricting disclosure to a selected group of qualified buyers.

9. Quality of Earnings

A buyer commonly begins its quality of earnings review after the letter of intent is signed. The review compares reported results and adjusted EBITDA with the recurring earnings the buyer believes it is acquiring. Material differences may lead the buyer to seek changes to valuation or other deal terms.

A quality of earnings review, commonly called a QoE, examines how the company generates profit and whether adjusted EBITDA reflects recurring performance. The buyer’s accounting firm tests revenue and expenses, including proposed earnings adjustments. Document each adjustment and reconcile the financial results with the marketing materials before outreach. Consistent, supported figures give you evidence to address proposed EBITDA adjustments and related valuation changes during the review.

10. Due Diligence

Due diligence usually runs for six to ten weeks after you sign the letter of intent, although weak records or complex deal terms can extend it. During this period, the buyer verifies the information provided before the LOI and investigates issues that could affect valuation or closing while attorneys negotiate the purchase agreement.

You should expect a significant documentation and coordination burden during diligence. Buyers may request detailed financial records, including monthly statements and tax returns. They will also examine customer contracts and records for insurance and employment. Your M&A advisor can coordinate with your accountant and attorney to manage requests and resolve inconsistencies, but you and your managers still need to explain the company’s records and operations.

Organized records allow you to answer diligence requests promptly. Complete responses also give the buyer less reason to request repeated follow-up materials or reserve judgment on unresolved issues. You should assign each request to a responsible person and maintain one controlled data room. You must also continue running the business while the review proceeds. Maintaining performance during exclusivity helps preserve the terms negotiated in the LOI.

11. Working Capital

For a transaction, working capital generally equals the specified operating current assets minus the specified operating current liabilities. The purchase agreement defines the included and excluded accounts. Buyers commonly expect the company to deliver a normal level of working capital at closing so the business can continue operating without an immediate cash contribution.

A working capital true-up compares the estimated closing balance with an agreed target and adjusts the purchase price after final figures become available. The target should account for seasonality and historical operating needs. Unclear definitions or an unsuitable target can create a dispute over the seller’s final proceeds.

12. Purchase Agreements

The final purchase agreement determines how much cash you receive at closing and how much remains subject to later adjustment. The closing statement starts with the agreed equity value, then accounts for debt, transaction expenses, estimated working capital, and any escrow holdback. Your M&A advisor should coordinate review of the statement with your attorney and accountant before you authorize the funds flow.

An escrow holdback places part of the purchase price with a third party for a defined period. Buyers may use the escrow to cover valid indemnification claims, such as losses caused by a breach of the seller’s representations in the purchase agreement. A basket sets a threshold for specified indemnification claims, although the agreement determines whether recovery applies only above that threshold or from the first dollar once the threshold is reached. A cap limits the seller’s exposure for specified claims. The agreement may apply different limits to matters such as taxes, ownership, or fraud.

13. Closing

A lower-middle-market transaction may close about 60 to 120 days after the letter of intent, although the quality of earnings review, working-capital negotiations, financing, and legal documentation can extend that schedule. The parties may sign the definitive purchase agreement and close on the same day, or they may schedule closing for a later date if financing, regulatory approval, or another closing condition remains outstanding.

At closing, the buyer wires funds according to the approved closing statement. You receive the net proceeds after the closing statement deductions. The working-capital true-up usually occurs after closing when final balance-sheet figures become available. Buyer delays or unresolved diligence issues can extend the six-to-nine-month planning range described at the start of this guide.

14. Post-Closing Transition

Closing does not always end the owner’s responsibilities. The purchase agreement may require transition assistance, and final working-capital figures or valid indemnification claims may still affect the proceeds retained after closing.

Before signing, clarify your expected role, decision-making authority, time commitment, and any remaining financial exposure. A defined transition plan helps the buyer assume control while giving employees, customers, and other important relationships a clear point of contact.

How M&A Advisory Fees Work: Success Fee vs. Retainer Models

M&A advisors typically charge a success fee when a transaction closes. Some advisors also require an upfront retainer or monthly work fee. A success fee may use one percentage for the entire transaction or a Lehman-style formula, which applies declining percentages to successive portions of the transaction value.

The Firmex North American M&A Fee Guide reports benchmark success fees of 6.3% for a $5 million transaction and 2.0% for a $100 million transaction. Its $20 million benchmark is 3.9%. In the Firmex benchmarks, the fee percentage declines as transaction value rises. The report’s figures describe market benchmarks rather than a fee rule that applies to every engagement. A larger transaction can still produce a much higher fee in dollars.

A quoted success-fee percentage may not show the engagement’s full cost. The engagement letter may include fixed or recurring charges beyond the success fee. Some advisors credit retainers and work fees against the success fee at closing, while others do not, and the Firmex M&A Fee Guide reports that more advisors have moved toward crediting work fees against the success fee and delaying fee payment when the seller is paid over time. The agreement should also explain how earnouts, rollover equity, assumed debt, and other forms of consideration affect the fee calculation.

Compare the total expected fee at a plausible sale value rather than comparing percentages alone. You should also determine what remains payable if no transaction closes and when fees become due if the buyer pays part of the purchase price later.

A success-fee-only model reduces your upfront cost and limits advisory fees if a sale does not close. An advisor using that model may charge a higher closing fee or require a minimum to compensate for the risk of completing months of unpaid work. A retainer model gives the advisor recurring compensation during the process, which can fit complex assignments that require substantial preparation even if the owner later decides not to sell.

Salt Creek’s standard M&A engagements use a success-fee model with no upfront retainer. Jack and Connor Pitts remain directly involved throughout the transaction. Our model may suit an owner who wants to avoid advisory fees before closing, while a retainer arrangement may fit an assignment that requires substantial preparation regardless of whether a sale closes.

How to Evaluate Any Sell-Side Advisor, Including Larger Investment Banks

Firm rankings do not tell you who will handle your transaction, how the advisor will approach buyers, or what you will pay. Evaluate each firm against four practical criteria and ask for specific answers before signing an engagement agreement.

Start with the full fee structure. Compare the success fee at a realistic sale price, any minimum fee, and any upfront or monthly charges. Ask whether retainers count toward the closing fee and what you owe if no transaction closes. Salt Creek’s standard engagements use a success fee with no upfront retainer, while other advisors combine a retainer with a closing fee.

Confirm who will perform the work after the engagement begins. Ask which senior banker will attend buyer calls and negotiate key terms. You should also learn who prepares materials and manages diligence. Direct principal access may matter if you want the same senior advisors involved throughout. A larger investment bank may instead divide execution among senior bankers and junior staff, so ask who will perform each part of the engagement.

Lincoln International illustrates an institutional advisory model that may suit larger or more complex transactions requiring broader sector or geographic coverage. Its staffing, fees, and transaction criteria may vary by office and engagement, so confirm the assigned team and scope directly with Lincoln International before comparing its services with Salt Creek’s principal-led model.

Review how the advisor builds and manages the buyer process. Ask how the firm identifies and qualifies buyers, then sets bid deadlines. The buyer list should include credible prospects whose acquisition history, strategy, or stated criteria provide a clear reason to consider your company.

Examine confidentiality practices before sharing sensitive information. A careful advisor should explain its disclosure controls, including blind teasers and nondisclosure agreements. Ask who approves each release and how the advisor handles potential competitors.

Choose an advisory model that fits your company’s size and transaction complexity. Consider the senior attention and closing support you expect, along with your budget and confidentiality needs.

Practices That Support a Successful Sale

• Reconcile financial statements and support adjusted EBITDA before starting outreach. Unsupported adjustments or discrepancies may lead buyers to revise their offers during the quality of earnings review or due diligence.
• Use a blind teaser to protect the company’s identity until a buyer signs a nondisclosure agreement.
• Check each buyer’s financial capacity and acquisition criteria before making contact so you focus on credible buyers and limit unnecessary disclosure.
• Consider a confidential market check before granting exclusivity to an unsolicited buyer. In Q1 2026, 83% of deals over $5 million attracted at least three offers.
• Compare the headline price with the offer’s payment timing and closing conditions.
• Resolve key LOI terms and set a reasonable exclusivity period before signing because exclusivity generally prevents you from seeking competing bids.
• Plan for your workload during due diligence so you can provide timely, consistent responses.
• Review the working capital target and all escrow and indemnification terms before closing because they affect how much cash you receive and retain.
• Evaluate the advisor’s staffing and buyer outreach plan as well as the full fee structure, including charges that apply if no transaction closes.
