What Is a Business Broker? The Complete Guide to Choosing the Right One

I got a call recently from a guy who had been trying to sell his HVAC company on his own for fourteen months. He had the financials in order, a solid customer base, and a business worth north of a million dollars. But every buyer he talked to either lowballed him, got spooked during due diligence, or just disappeared. When he finally asked me what went wrong, I told him the truth: he did not need a better buyer. He needed a broker.

A business broker is a licensed intermediary who manages the sale of privately held businesses, handling everything from valuation and marketing to buyer screening, negotiation, and closing. Think of it like selling a house, except the house has employees, customers, trade secrets, and a reputation that can evaporate the minute word gets out that it is for sale.

There are roughly 10,000 business intermediaries working across the United States right now. Some of them are excellent. Some of them will waste a year of your life. This article is about telling the difference.

Here’s What You Need to Know

• A business broker manages the entire sale of a privately held business, from initial valuation through closing, and typically earns a commission of 8 to 12 percent on Main Street deals under $1 million.

• Only 20 to 30 percent of businesses listed for sale actually close. Sellers who work with professional intermediaries are 60 to 70 percent more likely to complete a sale than those who go it alone.

• The two most respected industry certifications are the Certified Business Intermediary (CBI) from the IBBA and the Merger and Acquisition Master Intermediary (M&AMI) from M&A Source.

• Red flags include inflated valuations, no verifiable references, excessive upfront fees, and any broker who guarantees a specific sale price.

• Before signing a listing agreement, you should know exactly who will manage your deal day to day, what the tail period is, and what it costs to walk away.

What Does a Business Broker Actually Do?

The short answer: everything you do not want to do yourself while you are still running your business.

A broker starts by valuing your company. For most Main Street businesses, that means calculating Seller’s Discretionary Earnings (SDE) and applying an industry-standard multiple to arrive at a defensible asking price. For larger businesses, the broker uses EBITDA-based methods and may bring in a third-party appraiser. If you want a deeper breakdown of valuation methods and what drives them, we cover that in detail in our guide to valuing a small business.

After the price is set, the broker prepares marketing materials and posts a blind listing profile on platforms like BizBuySell and BizQuest. The word “blind” matters. The listing describes the business without naming it, because if your employees, customers, or competitors find out you are selling before you are ready, the fallout can be severe. I have personally seen deals collapse because a key employee caught wind of the sale and quit, taking three client relationships with them.

From there, the broker screens buyers. That means collecting NDAs, verifying financial capacity, and filtering out the tire-kickers. On a good listing, a broker might field 50 to 100 inquiries and narrow those down to a handful of serious, qualified prospects. Then comes negotiation, due diligence coordination, and closing. The whole process typically runs 6 to 11 months from engagement to close. If you want a step-by-step walkthrough of what selling looks like from the seller’s side, take a look at our guide to selling a small business.

That is a lot of moving parts. And it is exactly why the right broker earns their commission.

How Much Does a Business Broker Charge?

For businesses valued under $1 million, the standard commission is 8 to 12 percent of the final sale price, with 10 percent being the most commonly quoted figure. Most brokers in this range work on straight commission with no retainer, but they will have a minimum fee (typically $10,000 to $25,000) to make smaller deals worth their time.

For businesses in the $1 million to $5 million range, the Double Lehman formula is the most common fee structure. Here is how it breaks down:

Sale Price Increment	Commission Rate
First $1 million	10%
Second $1 million	8%
Third $1 million	6%
Fourth $1 million	4%
Everything above $4 million	2%

Under that structure, a $3 million sale generates a commission of $240,000 (that is $100,000 + $80,000 + $60,000). A $5 million sale comes to $300,000.

Once you get above $5 million in enterprise value, you are typically working with an M&A advisor rather than a traditional broker, and fees shift to retainers ($15,000 to $30,000) plus success fees in the 2 to 5 percent range. For deals above $100 million, investment bankers charge 1 to 2 percent.

Does the seller or the buyer pay the broker’s commission?

The seller pays. The commission is deducted from sale proceeds at closing. If the deal is co-brokered (meaning a buyer’s broker is also involved), the commission is typically split 50/50 between the two brokerages, but the full amount still comes from the seller’s side. The IRS classifies broker fees as transaction costs, and they are not currently deductible as a business expense.

Business Broker vs. M&A Advisor vs. Investment Banker

These three titles get used interchangeably, but they are not the same thing. The differences come down to deal size, process, and the types of buyers they can reach.

	Business Broker	M&A Advisor	Investment Banker
Deal Size	Under $2M–$5M	$2M–$50M	$50M+
Process	Passive (list and wait)	Active (managed auction)	Active (structured process)
Buyer Pool	Individual buyers	PE firms, strategic acquirers	Institutional, corporate
FINRA Licensed	Usually no	Usually no (exempt since 2022)	Yes
Fee Structure	8–12% commission	Retainer + 4–6% success fee	Retainer + 1–2% success fee

The biggest practical difference is process. A Main Street broker lists your business on marketplaces and waits for buyers to come to them. An M&A advisor builds a targeted list of potential acquirers and runs a competitive, timed process designed to generate multiple offers. For a $500,000 restaurant, the listing-and-waiting approach works fine. For a $5 million specialty manufacturing company, you want someone who is picking up the phone and calling the right buyers directly.

Here is my honest take: the title on someone’s business card matters a lot less than their track record and process. I have worked alongside brokers who call themselves “advisors” and do nothing more than post a listing on BizBuySell. And I have seen solo brokers who run tighter, more professional processes than some mid-market firms. Ask about what they do, not what they call themselves.

What Certifications Should a Business Broker Have?

There are two certifications that carry real weight in this industry.

The Certified Business Intermediary (CBI) is issued by the International Business Brokers Association. It requires 68 credit hours of coursework, attendance at an IBBA conference, a minimum of three completed transactions as lead broker, and a comprehensive exam. As of early 2026, there are nearly 500 active CBIs out of over 3,239 IBBA members. Getting the CBI takes at least two years and costs roughly $7,000 for initial certification plus about $3,000 annually after that. It is not easy to get, and that is the point.

The Merger and Acquisition Master Intermediary (M&AMI) is issued by M&A Source and is geared toward lower middle market deals. It requires three years of full-time deal experience, advanced coursework, and proof of three completed transactions each valued at $5 million or more. The M&AMI is widely considered the most rigorous credential in the space. Only a handful of practitioners hold it.

Do certifications guarantee a broker is good?

No. But the absence of any credentials combined with a thin track record is a strong negative signal. A broker who has invested the time, money, and effort to earn a CBI or M&AMI is telling you they take this profession seriously. That matters when you are trusting someone with the biggest financial transaction of your life.

Red Flags When Choosing a Business Broker

The business brokerage industry has low barriers to entry and high turnover. A lot of people hang a shingle, sell nothing for two years, and move on. Here are the warning signs I tell every client to watch for:

They let you set the price. If a broker asks what you think your business is worth and just agrees, walk away. A real broker does their own analysis using SDE or EBITDA multiples and presents a number with data behind it, even when that number is not what you want to hear. We see this enough that we built a separate business valuation service specifically to give sellers an honest, defensible number before they go to market.

They inflate the valuation to win the listing. This is the flip side. Some brokers will tell you your business is worth $3 million when the market says $2 million, just to get you to sign. Then the listing sits, the price eventually drops, and by then, buyers have moved on.

They have no references. If a broker cannot give you the names and phone numbers of three previous clients whose businesses they actually sold, that tells you everything you need to know.

They charge big upfront fees on small deals. A $30,000 valuation fee for a $500,000 business is not standard. It is a warning sign. Reputable brokers typically include valuations as part of their engagement or charge modest standalone fees.

They promise a specific price or timeline. Only 20 to 30 percent of listed businesses actually sell. The best brokers close roughly 40 to 50 percent of their listings. Anyone claiming 80 or 100 percent success rates is either cherry-picking their numbers or making things up.

They pressure you to sign fast. A broker who discourages you from having an attorney review the listing agreement, or who gets defensive when you ask about their credentials, is showing you how they will handle your buyer negotiations. Poorly.

What to Look for in a Listing Agreement

The listing agreement is the contract that governs the entire engagement. Unlike real estate, where listing agreements are standardized state forms, business brokerage agreements vary widely from firm to firm. That means there is room to negotiate, and you should.

Here are the terms that matter most:

Term length. Most agreements run 6 to 12 months, though 1 to 2 years is common given that businesses take a while to sell. Push for the shortest initial term with an option to extend. A shorter term gives you the ability to walk away if the broker is not performing.

Tail period. This is the window after the agreement expires during which the broker still earns a commission if the business sells to a buyer they introduced. Tail periods typically range from 6 months to 3 years (24 months is common). Make sure the agreement defines exactly what “introduction” means, and request a written list of all prospects covered by the tail.

Exclusivity. Most agreements are exclusive, meaning you owe a commission regardless of who finds the buyer. If you have existing relationships with potential acquirers, negotiate carve-outs for those specific parties before you sign.

Termination clause. Some brokers charge cancellation fees of $25,000 or more for early termination. Negotiate the right to terminate with 30 to 60 days written notice if the broker is not performing. At minimum, you should be able to terminate for cause.

Services list. The agreement should spell out exactly what the broker will do: valuation, marketing materials, listing on specific platforms, buyer screening, negotiation, due diligence coordination, and closing support. If the services section is vague or missing, that is a problem.

Boutique Firms vs. National Franchise Brokerages

The big franchise names in business brokerage (Sunbelt, Transworld, Murphy, VR, First Choice) offer brand recognition, shared training systems, and large buyer databases. That sounds good in a pitch meeting. But the quality of service varies drastically from one franchise office to the next, because you are not really working with the national brand. You are working with a local office owner and whatever team they have assembled.

Boutique firms tend to offer more direct access to senior practitioners, deeper specialization in specific industries or deal sizes, and more flexibility on terms. The trade-off is a potentially smaller buyer network and less geographic reach.

My advice: for a straightforward Main Street business in a common industry, a well-run franchise office with an experienced local broker can work fine. For a specialized business, or anything above $2 million in value, you probably want a firm with specific industry expertise and a proactive deal process. Either way, evaluate the actual person who will be managing your deal, not the logo on the letterhead.

Do I Actually Need a Broker to Sell My Business?

You are not legally required to use one. But the data is worth knowing. Sellers who work with professional intermediaries are 60 to 70 percent more likely to complete a sale compared to those who self-represent. Brokered deals also close at rates at least 20 percent higher than proprietary (unrepresented) deals. And a 2023 study by Search Investment Group found that 54 percent of successful acquisitions were sourced through a professional intermediary.

Could you sell your business yourself? Maybe. But you will be running your company and trying to market it, screen buyers, manage confidentiality, negotiate terms, coordinate due diligence, and close the deal. All while making sure your revenue does not drop, because nothing kills a deal faster than a business whose numbers are declining during the sale process.

That is the kind of situation we help sellers avoid at East Coast Advisory Team. We handle the sale so you can keep running the business that makes the sale worth doing in the first place.

The Bottom Line

Choosing a broker is one of the most consequential decisions you will make in the entire sale process. The right one protects your confidentiality, finds buyers you would never reach on your own, negotiates terms you would not think to ask for, and keeps the deal from falling apart when things get complicated (and they always get complicated). The wrong one wastes your time, overprices your business, and lets it sit on the market until it goes stale.

Do your homework. Check credentials. Ask for references. Read the listing agreement line by line. And if something feels off during the interview, trust that instinct.
