What a Business Broker Charges, and When It Is Worth It
The short answer
Most business brokers charge a success fee only when your business sells, commonly around 10% on smaller Main Street deals, with a typical minimum fee of $10,000 to $25,000. Larger lower-middle-market deals often use a scaled Lehman-style fee that shrinks as price rises. Some brokers also charge upfront or monthly retainers. A broker is usually worth it when you need real marketing reach, buyer screening, and someone to keep a deal from falling apart during diligence.

How broker fees are typically structured
Most business brokers work on a success fee, sometimes called a commission, that is paid only if and when your business actually closes. On smaller Main Street businesses, roughly those selling for under $1 million to $2 million, a commission around 10% of the sale price is common, though it can run higher on very small deals and somewhat lower as price climbs.
On larger lower-middle-market deals, brokers and M&A advisors often use a scaled fee structure sometimes called a Lehman formula or double Lehman formula. A classic version charges a higher percentage on the first slice of the deal value and progressively smaller percentages on each additional slice, so the blended rate falls as the sale price rises. The exact breakpoints and percentages vary a lot by firm, so treat any specific numbers you hear as a starting point for negotiation, not an industry standard.
Almost every listing agreement also sets a minimum fee, often somewhere in the $10,000 to $25,000 range for small deals, so the broker is not working for a token amount if your business sells for less than expected or the deal structure changes along the way.
Retainers, upfront fees, and what they should buy you
Some brokers ask for an upfront fee, a monthly retainer, or both, in addition to the eventual success fee. This is more common for businesses that need real preparation work before they can be marketed, or for advisors handling larger, more complex deals where months of unpaid work would otherwise be a lot to ask.
A reasonable retainer should buy you something concrete: a professional valuation opinion, a confidential information memorandum or offering document, a marketing plan naming the buyer channels they intend to use, and a defined amount of the broker's time. If a retainer is being charged but nobody can tell you what work it covers, that is worth pushing back on before you sign anything.
Retainers are sometimes credited against the final success fee and sometimes not, so ask directly. Either answer can be reasonable, but you want to know which one you are agreeing to.
Who actually pays the fee
In the vast majority of Main Street and lower-middle-market deals, the seller pays the broker's fee out of the sale proceeds at closing. Buyers occasionally engage their own buy-side advisor and pay that advisor separately, but that is a different arrangement from the fee a listing broker earns for representing you as the seller.
Because the fee comes out of your proceeds, it is worth modeling into your expected net, not treating as an afterthought. A hypothetical $10,000 fee difference on a $600,000 deal is real money, and it should factor into how you compare offers from different brokers or decide whether to sell on your own.
What a broker actually does for that fee
A good broker earns their fee by doing work you would otherwise have to do yourself while still running the business. That typically includes putting together a defensible valuation opinion, preparing marketing materials that present the business well without giving away identifying details, and listing it discreetly so employees, customers, and competitors do not find out prematurely.
From there, the broker screens inbound buyer inquiries, weeding out tire-kickers and people who cannot demonstrate financing, before you ever have to take a call. Once a serious buyer emerges, the broker manages the flow of due diligence requests, coordinates with your accountant and attorney, and generally acts as the buffer who keeps hard conversations from turning personal.
Perhaps the most underrated part of the job is simply keeping the deal alive. Small business deals fall apart constantly over financing hiccups, cold feet, or disagreements over minor terms, and an experienced broker who has seen those moments before can often talk both sides through them rather than letting the deal collapse.
M&A advisors and investment bankers: a different tier
As deal size grows, roughly into the multiple millions of dollars in enterprise value and especially into the lower middle market, the work shifts from a broker running a fairly standardized sale process to an M&A advisor or investment banker running a competitive, structured process aimed at private equity groups, strategic acquirers, or family offices.
These advisors typically build a more detailed offering memorandum, run a wider and more targeted outreach campaign, and manage a multi-round bidding process designed to create competitive tension between buyers. They also tend to be more involved in negotiating deal structure, earnouts, and financing terms.
This level of service generally becomes worth its higher cost once a business is large enough, and complex enough, that a competitive process could plausibly add more to the sale price than the incremental fee costs. There is no single dollar cutoff, but many owners start weighing this tradeoff somewhere in the $3 million to $5 million enterprise value range and up.
Exclusivity periods and tail clauses
Almost every listing agreement includes an exclusivity period, during which only that broker can represent the sale of your business. Typical terms run anywhere from six months to two years, and it matters because you are committing to work with one broker even if the process moves slowly or a better option appears elsewhere.
Nearly as important is the tail clause, which entitles the broker to their fee if you sell to a buyer they introduced within a set window after the listing agreement ends, commonly somewhere around six months to two years. Tail clauses exist to stop sellers from waiting out the agreement and then closing directly with a buyer the broker found, and they are standard practice, but the length and the definition of introduced buyer are both negotiable.
What to check before you sign a listing agreement
Before signing, read the fee structure carefully, including the minimum fee, and make sure you understand exactly what triggers it. Confirm the length of the exclusivity period and the tail period, and ask what counts as a buyer the broker introduced for tail purposes.
Ask what marketing will actually happen, which listing services or buyer databases will be used, and whether the broker has sold businesses in your industry or size range before. Ask how many active listings they are currently juggling, since an overloaded broker may not give your deal much attention.
Finally, check whether the agreement lets you walk away if the broker is not performing, and understand any early termination fees. Have an attorney familiar with business sales review the agreement rather than relying solely on the broker's own summary of its terms.
When selling without a broker can make sense
A broker is not always the right call. If you already have a known, credible buyer, such as a competitor who has expressed interest, a key employee ready to step up, or a family member, much of the marketing and buyer-screening work a broker does simply is not needed, and you may be better served putting that fee toward a good deal attorney and accountant instead.
Selling on your own can also make sense for a very small book of business or client list sale, where the buyer universe is narrow and the transaction is simple enough that formal marketing adds little. Similarly, in industries with a small number of active, well-known acquirers, such as certain specialty trades or professional practices, you may be able to reach out directly to the logical buyers yourself.
In all of these cases, you still benefit from an independent valuation opinion so you know your number is grounded in reality, and from professional help structuring and negotiating the deal itself, even without full brokerage representation.
Red flags to watch for
Be cautious of any broker who wants a large upfront fee but cannot clearly explain what marketing effort it funds, especially if they are vague about specific buyer outreach channels or timelines. A retainer tied to real deliverables is normal; a large check with no plan attached is not.
Also be wary of a broker who gives you an unusually high valuation to win your listing and then quietly walks it down over the following months once the business fails to attract offers at that price. A credible broker should be able to walk you through the reasoning behind their number, including comparable sales and cash flow multiples, rather than simply naming a flattering figure.
A hypothetical Main Street sale
Imagine a landscaping company sells for a hypothetical $700,000. The listing agreement sets a 10% success fee with a $20,000 minimum. Ten percent of $700,000 is $70,000, which is above the minimum, so the seller nets $630,000 before other closing costs. If the same business had instead sold for $150,000, the 10% fee would only be $15,000, below the $20,000 minimum, so the broker would be owed the $20,000 minimum fee instead, leaving the seller with $130,000. This kind of minimum fee is a normal part of many listing agreements and is worth checking for before signing.

Common questions
Is a 10% broker fee negotiable?
Often, yes, especially on larger Main Street deals or if you bring your own qualified buyer during the listing period. Some brokers hold firm on 10% for smaller deals since the dollar amount is already modest, but it never hurts to ask.
Do I still pay a broker if I find the buyer myself?
It depends on the listing agreement. Some agreements carve out a lower fee or no fee for buyers you introduce independently, while others treat the broker as exclusive for any buyer during the listing period. Get this in writing before you sign.
What happens if the deal falls through after diligence?
Success fees are, by definition, tied to closing, so if a deal collapses before closing you typically do not owe the success fee. Some agreements do allow the broker to keep a portion of any retainer already paid, so check that clause specifically.
How long does a typical listing agreement last?
Exclusivity periods commonly run from six months to two years, depending on the size and complexity of the business and how quickly the broker expects to find a buyer.
What is a tail clause and why does it matter?
A tail clause entitles the broker to their fee if you sell to a buyer they introduced within a set window, often six months to two years, after your listing agreement ends. It matters because it can still apply even after you have moved on to a different broker or decided to sell on your own.
At what size does an M&A advisor make more sense than a broker?
There is no fixed cutoff, but many owners start considering a dedicated M&A advisor or investment banker once enterprise value reaches roughly $3 million to $5 million and up, where a competitive, structured buyer process is more likely to add value beyond the higher fee.
Can I sell my business without a broker at all?
Yes, particularly if you already have a known buyer, a small and simple business, or operate in a niche with a handful of obvious acquirers. Even then, an independent valuation and experienced deal attorney are worth having.
What questions should I ask a broker before hiring them?
Ask about their fee structure and minimum fee, the exclusivity and tail periods, how many active listings they are currently handling, what specific marketing channels they will use, and whether they have closed deals in your industry or size range before.
