Exit advisory is a profession with low barriers to entry and high consequences for the client. Anyone with an investment banking background or an M&A book can hang a shingle. The owner-operator hiring one for the first time has limited basis to evaluate the choice in advance, and feedback only arrives months after the engagement letter is signed.

This page expands the seven-criterion framework introduced on the homepage. Each criterion is treated in long form, with the patterns observed in lower-middle-market transactions and the reasoning behind why the criterion matters.

01. Buyer-Lens Diligence

The most common failure mode in lower-middle-market exits is preparing a business for sale from the owner's perspective and then discovering, post-LOI, that the buyer's perspective is materially different. Strong advisors invert the order. They model the business from the buyer's underwriting framework before they prepare a teaser, before they build a confidential information memorandum, before they identify a single target acquirer.

Buyer-lens diligence is not market research. It is a structural exercise that maps the underwriting models a strategic acquirer, a financial sponsor, a family office, and a search fund would each apply to the same business. The four archetypes price the same earnings stream differently because their cost of capital, their hold period, their integration appetite, and their post-close operating thesis are all different. An advisor who has not done this mapping cannot tell the owner where the realistic valuation range sits, and cannot identify which preparation interventions will move the range up.

02. Pre-Process Preparation

The pre-process window is the 60 to 180 days before any buyer is approached. What happens during this window determines, more than any other variable, what the final transaction looks like. Quality of Earnings analysis runs during this window. Customer concentration normalization runs during this window. Working capital baseline modeling, owner-compensation addbacks, related-party transaction disentanglement, and the surfacing of any operational or contractual fragility, all of it happens before a single conversation with a buyer.

Industry data on sell-side Quality of Earnings supports this directly. DueDilio's 2025 analysis of lower-middle-market transactions documents a 0.5 to 1.5x multiple uplift attributable to sell-side QoE, with no-QoE deals averaging 4.2x EBITDA against 5.1x for QoE-backed deals. The differential is not the QoE document itself; it is the work the QoE forces the seller to do before going to market.

03. Realistic Valuation Modeling

An advisor who presents a single valuation number in a first meeting is either guessing or selling. The right answer is a range, with explicit assumptions, and with a stated view on which buyer archetype drives which end of the range. The right answer also acknowledges the gap between headline LOI value and final close value, which is a persistent pattern in lower-middle-market transactions.

GF Data's Small-Deal Resilience H1 2025 banding documents typical multiples by EBITDA size: businesses with $1 million to $5 million in EBITDA trading around 5.5x, $5 million to $10 million around 5.6x, and $10 million to $25 million in the 6.2x to 6.7x range. These are population averages, not deal-specific forecasts. An advisor's job is to position a specific business within the relevant band and explain the variance from band median.

04. Honest Post-LOI Forecasting

Post-LOI compression is the gap between the headline value an owner signs in the Letter of Intent and the actual value they receive at close. In the lower middle market, this gap is the rule, not the exception. The compression has structural drivers that experienced advisors can name in advance: working capital adjustment, customer concentration discovery, QoE restatements, escrow holdbacks, earnout structure, and PPA escrow.

The SRS Acquiom 2025 Deal Terms Study documents that 75 percent or more of lower-middle-market transactions include PPA escrow, with median PPA escrow at 1 percent of transaction value and average buyer-owed adjustments at 0.9 percent of transaction value. Earnouts pay materially below their maximum potential at close. The owner whose advisor named these patterns before LOI is not surprised by them at close.

05. Industry-Specific Experience

Exit advisory is not generic. M&A in residential services (HVAC, plumbing, electrical) runs differently from M&A in specialty distribution, B2B SaaS, healthcare practices, or family-owned manufacturing. Buyer archetypes differ by sector. PE roll-up activity is concentrated in fragmented services markets. Strategic acquisitions are concentrated in industries with synergy realism. Family offices favor operationally stable businesses with continuity narratives.

An owner-operator asking an advisor about industry experience should look for completed transactions in the same sub-sector and the same revenue band within the last 24 months. Older experience matters less than recent experience, because the underwriting frameworks shift with market conditions, capital availability, and sector-specific dynamics. An advisor who last sold a business in the relevant sector in 2019 is referencing a different market.

06. Methodology Over Promises

The first meeting with an advisor is, more than anything else, a methodology audit. Strong advisors walk the owner through their framework, their analytical approach, and their process. They explain how they think about buyer underwriting, how they sequence preparation work, how they assess deal readiness, how they manage the post-LOI phase. Their published research, their working papers, their writing on industry sites, all of it is evidence of how they think.

Weak advisors lead with logos. They show closed-deal references, photographs of conference panels, and aggregate transaction counts. None of this answers the question the owner needs answered, which is whether the advisor's methodology is sound for the specific transaction the owner is about to run.

07. Aligned Incentives

The structure of an advisor's fee determines the structure of their incentive. A 100 percent commission-based fee structure incentivizes closing speed. A retainer-plus-success structure incentivizes preparation quality. Owners who want the best transaction outcome, not the fastest one, hire on the second structure.

Retainer fees vary by transaction size. For a lower-middle-market engagement, a preparation retainer in the $25,000 to $100,000 range is typical, with success fees in the 1 percent to 5 percent range of transaction value depending on size and complexity. The specific numbers matter less than the structure. A retainer creates skin in the game for the advisor on the preparation phase, which is precisely the phase where the difference between competent and excellent advisory shows up.

Choosing in Practice

The seven criteria are a screening framework, not a scorecard. An advisor does not need to score perfectly on all seven. They do need to be defensibly strong on most of them, and they need to be honest about where they are not. The advisor who answers a question with "we are not the right fit for that" is more useful to the owner than the advisor who answers every question affirmatively.

The page Questions to Ask in Your First Meeting translates the seven criteria into 10 specific questions the owner can ask, with strong-answer and weak-answer signals for each. The page Red Flags to Avoid covers the inverse: patterns that, when present, justify ending the conversation early.
