How do I choose an M&A advisor to sell my business?

Look for an advisor who regularly closes deals your size in your industry, can give you references from sellers whose deals closed, and names the senior person who will run your deal. Interview more than one, verify licensing or the exemption they rely on, and have your attorney review the engagement letter before you sign.

What questions should I ask an M&A advisor before hiring them?

Ask how many deals like yours they closed recently, which buyers they would approach, who will do the work, how they reach a value range, the full fee structure, the exclusive term, how the tail provision works, which license or exemption they rely on, and whether they take any fee from buyers.

How are M&A advisors paid?

Usually through a success fee paid at closing and based on deal value, sometimes with a retainer or monthly fee, a minimum fee, a tiered or Lehman-style sliding scale, and reimbursed expenses. Compare engagement letters on how deal value is defined, the exclusive term and the tail provision, not just the headline fee.

What is a tail provision in an M&A engagement letter?

A clause that still owes the advisor a fee if you sell within a set period after the engagement ends. A fair tail covers only buyers the advisor introduced or contacted, listed by name. Ask for buyers you already knew to be carved out.

Does an M&A advisor need a license?

It depends on the deal and the state. Some intermediaries are registered with FINRA, which you can check on BrokerCheck. Many rely on the federal M&A broker exemption for smaller private companies, which has size thresholds and limits. Some states license business brokers. Ask which license or exemption they rely on.

Should I use a business broker or an M&A advisor?

Choose the kind of firm that regularly sells businesses your size. Brokers mostly sell smaller, owner-operated businesses through broad listings; M&A advisors mostly run targeted processes for larger companies with strategic and private equity buyers. Judge them by the deals they close, not the title.

How to Choose an M&A Advisor

Q: Is Axia an M&A advisor?

No. Axia is not an M&A advisor or a business broker. It is engaged and paid by buyers to introduce them to owners. It does not represent sellers, value businesses, negotiate terms or take part in diligence or closing, and it holds no business-broker license. Owners pay Axia nothing.

Selection criteria: how to judge an M&A advisor or broker

Criterion	What good looks like	How to check it	Red flag
Deal size fit	Most of their recent closed deals are close to your size. Your business would be a normal engagement for them, not their smallest or largest.	Ask for the range of deal sizes they closed recently and where yours would sit in it.	They talk about one large headline deal but can't describe recent deals your size.
Industry experience	They have sold businesses in your industry or a close neighbor, and they know which buyers are active in it and how those buyers judge a business.	Ask which deals in your sector they closed and which buyer types bought them.	Every industry is a fit, and they can't name the issues buyers in your sector focus on.
Closed deals and references	They can point to closed deals, not just listings or signed engagements, and will put you in touch with former clients.	Call at least a couple of former sellers. Ask how close the final price came to the first range they were given and how the process went.	No references, only testimonials, or references who never actually closed.
Buyer reach and process type	They can explain the process they would run for you (a broad listing, a targeted auction, or a negotiated sale with a short list) and why it suits your business.	Ask what kind of buyers they would approach, how they find them, and how many they expect to contact in your case.	One process for everyone, or a buyer list that is mostly a website listing.
Who does the work (senior vs junior)	The senior person you meet stays on the deal, leads buyer calls and negotiations, and is named in the engagement letter.	Ask who will run your deal day to day, who will be on buyer calls, and who negotiates the letter of intent.	A senior partner pitches, then a junior analyst you never met runs the process.
Fee structure and engagement terms	Fees, expenses, exclusivity, termination and the tail provision are written clearly and explained without pressure.	Get the full engagement letter in advance and have your M&A attorney read it before you sign.	Large upfront fees with little tied to closing, a long exclusive term, or a tail that covers every buyer forever.
Licensing and registration	They tell you which license, registration or exemption they rely on and you can verify it.	Search the firm and individuals on FINRA BrokerCheck, check any state business-broker license where it applies, and ask which exemption covers them if neither does.	Vague or annoyed answers about licensing, or disciplinary history they did not mention.
Conflicts of interest	They disclose any relationships with likely buyers, any fees they receive from buyers, and whether they ever represent both sides.	Ask directly whether they are paid by anyone other than you on this deal, and get the answer in writing.	They also take fees from buyers, or propose representing both sides, without clear written disclosure and your consent.
Chemistry and communication	You trust them, they explain things plainly, they return calls, and they tell you things you don't want to hear.	Notice how they handle the interview: whether they listen, how fast they respond, and whether their valuation range is reasoned or flattering.	The highest valuation in the room with no support behind it, or pressure to sign quickly.

The short answer

Picking the person who sells your business is one of the few decisions in a sale that you make before any buyer is involved, and it shapes everything after. A good advisor brings the right buyers, keeps the process moving, and negotiates for you. A poor fit can cost you months under an exclusive agreement, a weak price, or a deal that falls apart in diligence.

The selection criteria table above is the checklist. In practice, three things matter most: whether they regularly close deals like yours, whether the senior person you meet will do the work, and whether the engagement letter is fair if the sale doesn't happen. Everything else on this page helps you test those three.

If you have not yet decided whether you need an intermediary at all, start with should I use a business broker? and can I sell my business without a broker?. For the overall sale sequence, see how to sell a business.

Business broker or M&A advisor: start with deal size

The titles overlap and nobody enforces them, so judge the person by the deals they close rather than what they call themselves. As a rough guide, business brokers mostly sell smaller, owner-operated businesses by listing them to a broad pool of buyers, often individuals. M&A advisors mostly sell larger companies through a targeted process with strategic and private equity buyers. Many firms sit somewhere in between.

The practical question is which kind of firm regularly sells businesses the size of yours. A firm used to much larger deals may treat yours as a low priority; a firm used to much smaller deals may not know the buyers who would pay most for it.

Questions to ask before you sign

Ask every candidate the same questions so you can compare the answers side by side. Write the answers down during the meeting. Good advisors are used to these questions and answer them directly.

How many deals like mine have you closed recently, and can I speak with some of those sellers?
What deal sizes do you usually work on, and where would my business sit in that range?
Which deals in my industry have you closed, and what kinds of buyers bought them?
What process would you run for my business, and why that one?
Which buyers would you approach first, and how do you find buyers who are not on your list already?
Who will run my deal day to day, and will you personally be on buyer calls and in negotiations?
How do you arrive at a value range, and what would make the final price come in lower?
What do you charge in total, what is due before closing, and what is due only if the sale closes?
How long is the exclusive term, and how can either of us end the engagement early?
How does the tail provision work, and which buyers would it cover after the engagement ends?
Which license or registration do you hold, or which exemption do you rely on?
Do you receive any fee or benefit from buyers, and have you ever represented both sides of a deal?
How will you protect confidentiality, and when would my employees or customers learn about the sale?
How often will you report to me, and what will those updates include?
What happens if a buyer I already know about makes an offer during the engagement?

How fees and engagement terms are structured

We don't quote fee levels here. We have no sourced figure we are willing to stand behind, and fees vary by firm, deal size, region and how much work the deal takes. What we can do is explain the pieces you will see in an engagement letter, so you can compare offers on structure, not just on the headline fee.

Success fee. The main fee, paid at closing and calculated on the deal value. Check exactly how deal value is defined: whether it includes debt the buyer assumes, seller notes, earn-out payments, consulting agreements and any real estate. The broader the definition, the more the fee grows. If part of your price is deferred, ask whether the fee is paid on the deferred amount at closing or only when you actually receive it. See earn-outs and seller notes for how deferred payments work.
Retainer or monthly fee. Some advisors, more often on larger deals, charge an upfront or monthly fee for preparing materials and running the process. Ask whether it is credited against the success fee at closing, whether it stops after a set period, and what you get for it.
Minimum fee. Some engagement letters set a minimum success fee so that a smaller-than-expected deal still pays the advisor a set amount. Check how it compares to the fee you would owe at your realistic price, not your hoped-for price.
Tiered or Lehman-style scales. Instead of one rate, the fee is a sliding scale: a higher rate on the first slice of the price and lower rates on each slice above it. Ask for a worked example at a few prices so you can see what you would actually pay.
Expense reimbursement. Travel, data room software, marketing and outside research may be billed on top of fees. Ask for a cap and for approval before large expenses.
Exclusivity term. The period during which only this advisor can sell your business. Compare its length to how long sales actually take, and check whether you can end it early if the advisor is not performing.
Tail provision. A clause that still owes the advisor a fee if you sell within a set period after the engagement ends. A fair tail is limited to buyers the advisor actually introduced or contacted, listed by name when the engagement ends. Watch for tails that cover any buyer at all, or that run for a long time.
Termination. What either side owes if the engagement ends, how much notice is required, and whether any unpaid retainer still comes due.

How to read the engagement letter

The engagement letter is a contract, and it usually favors whoever wrote it. Have your own M&A attorney read it before you sign. The SBA recommends consulting lawyers, accountants and valuation experts when you sell a business [3], and the engagement letter is the first document where that advice pays off. Read it in this order:

Scope. What exactly the advisor will do: valuation, marketing materials, buyer outreach, negotiation, diligence support. Anything not listed is not promised.
Fees. Every fee, when it is due, and how deal value is defined. Ask for a worked example at your realistic price.
Exclusivity and term. How long it lasts, how it renews, and whether it renews automatically.
Tail provision. How long it runs and which buyers it covers. Ask for buyers you already know to be carved out by name.
Termination. How either side can end it, with what notice, and what is owed.
Expenses. What is billed on top of fees, any cap, and whether you approve large items first.
Conflicts and other fees. A statement that the advisor will not take fees from buyers without your written consent.
Confidentiality. How the advisor will protect your information and what buyers must sign before they see it.
Licensing. Which license, registration or exemption the advisor relies on, stated in writing.

Licensing and registration: what to check

Selling a company can involve securities law, especially when the deal is a sale of stock or membership interests. Many intermediaries who are paid a success fee rely on the federal M&A broker exemption in 15 U.S.C. 78o(b)(13) rather than registering as a broker-dealer [1]. The exemption only covers the sale of an eligible privately held company, which in the fiscal year before the engagement had EBITDA under $25,000,000 or gross revenues under $250,000,000 [1].

The exemption comes with limits [1]. An M&A broker relying on it may not receive, hold, transmit or have custody of the funds or securities exchanged in the deal. It may not bind a party to the transaction. It may not represent both the buyer and the seller without clear written disclosure to, and consent from, both. It may not provide financing for the deal. And it is not available to people who are barred or suspended. If an advisor proposes to hold your sale proceeds, sign for you, or act for the buyer as well, ask how that fits within the exemption.

Registered representatives are easy to check. FINRA BrokerCheck is a free lookup tool where you can search a broker or firm and see registration and any disciplinary history [2]. Search both the firm and the individuals who will work on your deal.

Some states separately license business brokers, sometimes through their real estate licensing rules, particularly when real estate or a lease is part of the sale. Rules differ by state, so ask your attorney what applies where your business is located. The simplest test is to ask every candidate which license, registration or exemption they rely on and to put it in the engagement letter. A good advisor answers that question without hesitation.

If you need a formal appraisal, for example for a partner buyout, an estate or gift plan, or a lender, use a valuation professional who holds a recognized business valuation credential and whose report is written to professional appraisal standards. An advisor's opinion of value is useful for pricing a sale, but it is not the same thing as an independent appraisal.

How to run the interview process

Talk to more than one advisor. You learn more from comparing answers than from any single pitch, and you will see quickly which valuation ranges are reasoned and which are flattering. Plan the interviews before you start:

Get your numbers in order first. Have recent financial statements and tax returns ready, and calculate your SDE or EBITDA. If you are not sure which applies, read SDE vs EBITDA.
Know your own range. Check the multiples index, which shows median EBITDA and SDE multiples by sector and size band [6], and run your earnings through the value range calculator. The SBA recommends valuing a business before marketing it [3]. With your own range in hand, an inflated pitch is easier to spot.
Build a short list. Ask your attorney, CPA, banker and owners you know who have sold for names. Prefer firms with recent closed deals in your size and sector.
Sign an NDA before sharing detail. Share enough for the advisor to give an informed view, and keep customer names and contracts back until you choose one.
Ask every candidate the same questions. Use the list above, and take notes.
Call references. Speak to sellers they represented, not only the ones they choose for you, and ask what they would do differently.
Compare engagement letters side by side. Line up fees, exclusivity, tail and termination, and have your attorney review the one you prefer before you sign.

How long you will be working together

Choose someone you can work with for months. In the International Business Brokers Association and M&A Source Market Pulse survey for Q2 2026, the time from engagement to close averaged 6 to 10 months for businesses under $2 million in enterprise value, and 11 to 12 months for businesses between $2 million and $50 million [4]. The same survey reported that for the $2 million to $5 million segment, the average rose from 9 to 11.5 months in Q2 2026 [4].

That is why the exclusivity term, the termination clause and communication style matter as much as the fee. If the advisor's exclusive term is shorter than a realistic sale process, you may face a renewal negotiation mid-deal. If it is much longer and the advisor stops working the deal, you need a clean way out. Due diligence takes a large share of that time, so see business sale due diligence for what buyers will ask for.

Red flags

Any one of these is a reason to slow down and ask more questions. Several together are a reason to keep looking.

A valuation far above every other candidate's, with no closed deals or market data behind it. Some firms win engagements by promising a high price and then work it down once you are locked in. See asking price vs sale price for why the two differ.
Large upfront fees with little of their pay tied to closing.
An exclusive term with no early exit, or a term that renews automatically.
A tail that covers any buyer, including buyers you already knew, for a long period.
No references from sellers whose deals actually closed.
Evasive answers about licensing, or disciplinary history on BrokerCheck they did not mention.
A plan to take fees from buyers or represent both sides without clear written disclosure and your consent.
Pressure to sign at the first meeting or before your attorney has read the letter.
Unclear answers about who will actually run your deal.
No questions about your goals, your timing, your employees or what you want after the sale.

What to do before you hire anyone

You get better advisors, and better terms, when your business is ready to sell. Clean financials, documented add-backs, customer contracts in order and a management team that can run the business without you all make you a more attractive client and a more attractive target. See what increases business valuation and what buyers look for in a business for what buyers pay for.

Timing matters too. If you are still deciding whether this is the right year, read when to sell your business before you sign an exclusive agreement. If confidentiality is your biggest worry, read how to sell a business confidentially and ask every candidate how they would protect it. And talk to your CPA about how the deal structure affects your tax before you set a target price; taxes when selling a business covers the basics.

Where Axia fits, and what it does not do

To be clear about our own role: Axia is not an M&A advisor, and it is not a business broker. Axia Growth works on the buyer side. Buyers such as private equity firms, search funds, strategic acquirers and holding companies set acquisition criteria and engage Axia to find privately held companies that fit. Axia calls those owners and introduces the interested ones to the buyer. The buyer pays Axia. Owners pay Axia nothing, whether or not they sell [5].

Axia does not represent sellers, value businesses, negotiate terms, structure deals, or take part in due diligence or closing, and it holds no business-broker, real estate or securities license [5]. If an Axia introduction leads to a serious conversation, everything on this page applies: you may want your own M&A advisor or broker to test the offer against other buyers, and you should have your own M&A attorney and CPA. See who pays for how the model works.
