Why this decision matters more than it looks
Most business owners sell exactly one company in their lifetime. Your advisor has (hopefully) done this dozens of times, which means the information gap between you and the buyers you'll face is closed almost entirely by whoever you hire to represent you.
A strong advisor runs a competitive process, keeps buyers honest about valuation, catches deal-killing issues before they surface in diligence, and knows when to walk away from a bad term. A weak one, even a well-intentioned one working outside their actual experience, can cost you materially more than their fee, in price, terms, or a deal that falls apart late and burns the relationships you'd need to try again.
The advisor's brand name matters less than whether they've closed deals at your specific size, in your specific industry, recently. A boutique that closes ten deals a year exactly like yours will usually outperform a famous firm that's never worked at your scale.
Advisor, investment bank, or business broker?
These terms get used loosely, and the lines blur in the middle market, but the distinction matters for what kind of process you should expect.
| Term | Typical Deal Size | What They Do |
|---|---|---|
| Business Broker | Under $5M, often much smaller | Lists businesses similarly to real estate; largely transactional, limited negotiation depth. |
| M&A Advisor | $5M–$500M (roughly) | Runs a structured, competitive sale process; manages buyers, negotiation, and diligence coordination. |
| Investment Bank | $100M and up | Full-service M&A, capital markets and financing capability; typically not economical below the lower middle market. |
These ranges overlap heavily in practice, many firms calling themselves "M&A advisors" or "investment banks" serve the same $10M–$100M range. See our full M&A Advisor vs. Business Broker comparison for more detail.
What actually distinguishes advisors from each other
- 01
Deal-size fit, not just range
A firm listing "$5M–$500M" as their range doesn't treat a $15M deal and a $300M deal the same way. Ask how many deals they've closed near your specific size in the last two years, not their broadest possible range.
- 02
Industry-specific experience
Sector fluency shows up in the buyer list, the diligence questions anticipated, and how the business is positioned. A generalist can still run a good process, but real vertical experience is a genuine edge, especially in regulated industries like healthcare.
- 03
Who actually runs your deal
The partner in your pitch meeting isn't always the person running your process day to day. Ask directly who you'll work with, and how much of their time is genuinely available to you.
- 04
Buyer network relevant to your business
A broad buyer list is worth less than a targeted one. Ask what strategic acquirers and financial buyers they'd realistically approach for a company like yours, and why.
- 05
Fee structure and alignment
Most advisors combine a retainer with a success fee, often on a Lehman-style sliding scale. Confirm the structure aligns their incentive with getting you the best outcome, not just closing quickly. See our M&A Advisor Fees guide for typical structures.
- 06
References from comparable past clients
Ask for, and actually call, references from sellers in a similar industry and size range, ideally from the last one to two years, not a curated list of their best-ever outcomes.
Questions to ask every advisor you interview
- 01How many deals have you closed in the last 24 months between [your revenue] and [your revenue]?
- 02Who specifically will run my deal day to day, and how many other active deals will they have at the same time?
- 03What does your typical buyer list look like for a company like mine, and how many of those buyers have you actually transacted with before?
- 04What's your fee structure, including retainer, minimum fee, and success-fee breakpoints?
- 05Can I speak with two or three past clients in a similar industry and size range?
- 06What's the single biggest reason a deal you've run has fallen apart, and what would you do differently?
Red flags to watch for
- ✕
Valuation that's noticeably higher than every other advisor you talk to
An inflated initial valuation is sometimes used to win the engagement, then quietly walked back once you're committed. Get multiple opinions before you sign.
- ✕
Vague answers about who'll actually run your deal
If an advisor can't tell you clearly who your day-to-day contact will be, assume it won't be the senior partner you're meeting with now.
- ✕
No client references, or only references from a decade ago
Recent references in your size range and industry are reasonable to expect. Reluctance here is worth taking seriously.
- ✕
Pressure to sign quickly, before you've compared other firms
A good advisor is confident enough in their fit to let you shop the decision. Urgency without a clear reason is a signal, not a coincidence.
Narrowing the field
Start by filtering to advisors who actually match your industry and deal size, not the most recognizable names. Our Top 100 directory is filterable by both, along with market segment and location, and every firm's profile shows the confidence level behind each data point rather than presenting everything as equally certain.
If you'd rather skip the filtering yourself, our Find an Advisor intake matches your industry, size and timeline against the directory directly.
