When to use this playbook

What success looks like

You select an advisor who (1) has repeatable wins in your deal-size band, (2) demonstrates sector pattern recognition, (3) runs a clock-driven process with clear artifacts (calendar, tracker, LOI grid), and (4) can be independently validated via founder references and counterparty-confirmed transactions.

Step-by-step selection process

Step 1: Define your transaction needs (before you talk to advisors)

Write a one-page “decision brief” covering:

Why: Advisors will tailor buyer outreach, process design, and negotiation strategy based on what you actually optimize for—often not just price.

Step 2: Pick the right advisor type (match complexity and deal size)

This is a “fit-to-problem” decision, not a prestige decision.

Advisor type Best for Typical strengths Watch-outs
Boutique M&A advisory firm Lower middle market, founder-led transactions; sector-focused deals Senior attention, process discipline, targeted buyer coverage Quality varies by firm; validate team and track record
Investment bank Larger or more complex deals; cross-border/capital markets adjacency Larger platform, broader buyer universe, specialized teams May be less senior-led for smaller deals; higher overhead
Business broker Smaller, simpler transactions; local/regional buyers Speed, local reach Often less process rigor for complex diligence/terms; may skew toward smaller deal sizes

Step 3: Use an evidence-first evaluation rubric (the “8 checks”)

Dimension What “good” looks like Evidence to request
Deal-size fit Repeat wins in your size band 5–10 comparable engagements (role, outcome, year)
Sector fit Pattern recognition (buyers, diligence traps, narrative) Sector-specific buyer theses; diligence risk plan
Buyer access Current relationships with likely buyers Tailored sample buyer list (not generic logos)
Process discipline Clock-driven milestones and artifacts Calendar, tracker, LOI comparison template
Team quality Senior-led execution Named deal team; who writes materials; who negotiates
Negotiation strength Protects terms and reduces re-trades Examples: term improvements; re-trade defense approach
Verification Claims can be independently validated Founder references; counterparty-confirmed transactions
Alignment Fees and incentives are understandable Clear retainer/success structure; scope; termination terms

How to think about “verification”: a credible advisor can usually point to public announcements naming them as advisor, and/or provide references who will confirm their role and performance.

Step 4: Interview 3–5 advisors (use questions that reveal execution)

Ask for specifics that produce artifacts, not opinions:

  1. Who is the exact deal team (names/roles), and what will each person do weekly?

  2. Show a sample process calendar and weekly cadence (what gets sent, when).

  3. What does your buyer list look like for a business like mine (and why those buyers)?

  4. How do you structure outreach waves, deadlines, and bidder competition?

  5. What are the most common diligence failure modes in my subsector (education/healthcare), and how do you reduce them pre-launch?

  6. How do you prevent and respond to re-trades (price/terms changes late-stage)?

  7. What are your engagement terms (exclusivity, termination triggers, scope boundaries)?

  8. Provide 3–5 founder references from comparable deals in the last 24–36 months.

Step 5: Verify track record (how to do reference checks that matter)

Request 3–5 references and ask questions that surface execution quality:

Also triangulate publicly where possible:

Step 6: Review engagement terms (avoid common traps)

Term What to evaluate Practical guidance
Exclusivity Length and performance expectations Ensure you have termination options if cadence/milestones are missed
Scope What’s included (materials, outreach, diligence coordination, negotiation) Confirm whether QoE support and data-room management are in scope
Fees Retainer/engagement fee + success fee structure Focus on clarity and alignment, not just the lowest number
Expenses Reimbursables and caps Require pre-approval thresholds and itemization
Conflicts Competing mandates and buyer conflicts Require disclosure and recusal process where relevant

Typical timeline to select an advisor

Most founders can complete selection in ~3–5 weeks if they run a structured process (your pace may vary based on urgency and data readiness).

Phase Typical duration Key activities
Shortlist creation 1–2 weeks Identify 8–15 candidates; narrow to 3–5 interviews
Interviews 1–2 weeks Structured interviews; request artifacts (calendar, buyer list, team)
Reference checks 3–5 days Founder calls; triangulate public deal evidence
Proposal comparison 3–5 days Compare scope, exclusivity, fees, and termination
Select & onboard ~1 week Execute engagement; begin prep work

Fee structure: what is common (benchmarks, not guarantees)

Fee structures vary widely by deal size, complexity, and advisor model. Market surveys and owner-focused guides commonly describe combinations of (a) a monthly retainer/engagement fee and (b) a success fee that often declines as deal size increases.

Important: Treat benchmarks as starting points. Your actual fee proposal should be evaluated against scope, senior involvement, and the process artifacts the advisor commits to deliver.

Credentials: what matters (and what doesn’t)

Credentials are not substitutes for execution, but they can signal baseline training—especially in valuation-heavy contexts.

Practical guidance: prioritize (1) verifiable deal experience in your size band and sector, (2) process discipline, and (3) references over credential lists.

When you might not need an M&A advisor (or need a narrower scope)

You may not need a full sell-side advisor if:

Safer alternative: Even in “no advisor” scenarios, many founders still engage for a targeted scope (valuation opinion, negotiation support, or deal-structure review) to reduce re-trade risk and improve terms.
