I’m not a broker and I don’t charge sellers anything — I’m a buyer. But I’ve seen enough deals to know that owners often focus on one number in a broker agreement and miss the clauses that cost them more. This page is about reading the whole agreement.
You won’t find fee percentages here. They vary by deal size, broker, market and timing, and any figure I printed would be wrong for someone. What I can do is show you how the pieces fit together so you can compare offers intelligently.
The common fee structures
Success fee
The most common structure. The broker is paid at closing, usually calculated on the transaction value. If the business doesn’t sell, there’s typically no success fee. That aligns the broker with getting a deal done.
Watch: how “transaction value” is defined. Does it include seller financing, earnouts, consulting agreements, real estate, inventory or assumed debt? Is the fee on an earnout paid when you actually receive the earnout, or upfront on money you may never get?
Tiered or sliding formulas
Some brokers and M&A advisors use a formula where the rate changes as the price rises. These can reward the advisor for pushing price up, which can be good for you. Understand how each tier works before signing.
Upfront or monthly retainers
More common with M&A advisors and larger deals, sometimes with brokers. A retainer pays for preparation and marketing work regardless of outcome.
Ask: Is the retainer credited against the success fee at closing? What exactly does it pay for? Can you exit the agreement, and what happens to the retainer if you do?
Minimum fees
Many brokers set a minimum success fee so smaller deals are worth their time. On a smaller sale, the minimum may effectively be the fee. Know the minimum before you compare rates.
Valuation or packaging fees
Some charge separately for an opinion of value, a formal valuation or preparing marketing materials. Ask whether these are optional and whether they are credited later.
The contract terms that matter as much as the fee
| Term | What it means | What to ask |
|---|---|---|
| Exclusivity | Only this broker can earn a fee during the term | How long? Can I exclude buyers I already know? |
| Term length | How long the agreement lasts | Is there an early exit? What does it trigger? |
| Tail clause | Fee owed for later sales to certain buyers | Which buyers? For how long? Requires a written list? |
| Excluded parties | Buyers you name upfront who don’t trigger a fee | Can I list my managers, competitor or a known buyer? |
| Fee definition | What the fee is calculated on | Does it include notes, earnouts, real estate, debt? |
| Expenses | Marketing and travel reimbursement | Capped? Pre-approved? |
Comparing broker proposals
Don’t compare headline rates. Compare total expected cost and expected outcome:
- Total fees under realistic price scenarios, including minimums and retainers.
- What you get — preparation, valuation work, marketing reach, buyer screening, deal management.
- Track record — similar businesses sold recently, and how close final prices came to asking.
- Terms — exclusivity, tail, exit rights, exclusions.
- Fit — do you trust them to represent you when it gets hard?
A cheaper broker who can’t find the right buyer costs more than a more expensive one who can. And a great broker with a punishing tail clause may still be the wrong choice if you already have a likely buyer.
Taxes and fees
Broker fees are typically a selling expense, which affects your net proceeds and your tax picture. How they’re treated depends on your deal structure and entity. Ask your CPA to model it. See asset sale vs stock sale.
When the fee is worth it
A broker’s fee is usually worth paying when the broker:
- Reaches buyers you couldn’t.
- Creates competition that improves price or terms.
- Keeps the deal from collapsing.
- Saves you time you’d otherwise pull from running the business.
- Protects you from mistakes that cost more than the fee.
When a direct sale may make more sense
If you already have a strong buyer in view, a simple business or a priority on confidentiality and fit, talking with a direct buyer first can be worthwhile. You’ll still use your own attorney and CPA. See sell a business without a broker.
Negotiating the agreement
Most terms are more negotiable than owners assume. Reasonable requests include a shorter initial term with renewal, a narrower tail limited to buyers the broker actually introduced and listed in writing, exclusions for buyers you already know, caps on reimbursed expenses and clarity on how deferred payments are handled. A good broker won’t be offended. A broker who refuses every request is telling you something about how the relationship will go.
Questions to ask before you sign
- What is every fee I could owe, in every scenario?
- How is the sale price defined for the fee?
- What happens if I sell to someone I found myself?
- How long is the agreement, and how do I end it?
- What exactly does the tail clause cover?
- Which expenses will I reimburse?
- Can I see your agreement in advance to review with my attorney?

Questions people ask
How much does a business broker charge?
Fees vary by deal size, broker, region and structure. Most brokers charge a success fee at closing, and some add upfront or monthly retainers or minimum fees. Ask for every fee in writing and compare total cost, not just the headline rate. This site does not publish fee figures because they change and vary widely.
Who pays the business broker fee?
In most small business sales the seller pays the broker from the sale proceeds at closing, under the engagement agreement the seller signed. Buyer-side advisors are paid by buyers.
What is a tail clause in a business broker agreement?
A tail clause says the broker still earns a fee if you sell to a buyer they introduced — or sometimes any buyer — within a set period after the agreement ends. Its scope and length are negotiable; have your attorney review it.
