A business broker sold a $900K HVAC company in four months. The seller paid $72,000 in commission — 8% — and walked away feeling it was worth every dollar. A different seller paid $54,000 to a different broker on a $600K landscaping deal, got three unqualified offers over nine months, and eventually sold through a direct referral the broker had nothing to do with. The difference wasn't the commission structure. It was the broker. Choosing the right one and knowing how to work with them is the difference between a smooth exit and an expensive disappointment.
What a Business Broker Actually Does
Most sellers have a vague idea that brokers 'handle the sale,' but the actual scope of what a broker does — and does not do — matters when you are deciding whether to hire one.
**What brokers do:** Brokers package your business for sale — they prepare the Confidential Information Memorandum (CIM), set the asking price, and create the listing. They market your business across platforms including BizBuySell, their own buyer database, and sometimes industry-specific channels. They field initial inquiries, screen buyers for financial qualification, circulate NDAs, and manage the document flow. They facilitate introductory calls between you and qualified buyers, assist with LOI negotiation, and coordinate the due diligence process through to closing.
**What brokers do not do:** Brokers are not transaction attorneys — the purchase agreement, asset transfer documents, and reps and warranties come from a lawyer you hire separately. Brokers are not CPAs — tax structuring, deal structure optimization, and post-sale financial planning require your own advisors. Brokers are not business valuation experts in the formal sense — most use rules-of-thumb multiples rather than formal appraisals, and some will set an inflated asking price to win the listing.
**The honest value proposition:** A good broker saves you 5–15 hours per week of buyer management work, brings a pre-existing buyer database you don't have, and provides deal process experience that prevents expensive mistakes. For sellers who are running a business full-time and cannot absorb that workload, or who have never been through a sale before, a broker's time savings and process guidance are genuinely valuable. For sellers who have time and prior transaction experience, the math is harder to justify.
How Much Does a Business Broker Cost
Broker compensation is almost always a commission on the sale price, paid at closing. Understanding the typical structure before you sign a listing agreement prevents surprises.
**Commission rates by deal size:**
Below $1M: 8–12% of sale price. On a $600K sale that's $48K–$72K. This is the range where broker fees hurt most relative to deal size, and where a DIY sale is most viable for sellers with time.
$1M–$5M: 5–8% of sale price. Some brokers use a Lehman formula or modified Lehman: 10% on the first $1M, 8% on the next $1M, 6% on the next, and so on. Confirm the exact structure in writing before you sign.
Above $5M: Typically 3–5%. At this size, M&A advisors (investment bankers focused on the lower middle market) replace traditional business brokers, and fee structures include retainers plus success fees.
**Other fees to watch for:** Some brokers charge an upfront listing or marketing fee, typically $500–$2,500. This is not standard and not always justified — it exists primarily as a commitment signal. Brokers who charge upfront fees while also taking a commission are double-dipping. Ask what the fee covers specifically and whether it is credited against the commission at close.
**Exclusivity period:** Most listing agreements require 6–12 months of exclusivity. During this period, even if you find the buyer yourself through your own network, you owe the broker a commission. Read this clause carefully. Negotiate for a shorter exclusivity period (6 months) with a renewal option, and confirm whether the agreement covers buyer introductions the broker made before the listing expired.
- Under $1M sale: 8–12% commission ($48K–$120K on a $1M deal)
- "$1M–$5M sale: 5–8% commission, sometimes Lehman formula"
- Above $5M: 3–5%, plus possible retainer
- Watch for upfront listing fees ($500–$2,500) — negotiate credit at close
- Exclusivity period: 6–12 months standard, negotiate 6 months with renewal
- Tail clause: broker may claim commission on buyers introduced during listing period even after expiration
How to Choose the Right Business Broker
The broker market is fragmented and quality varies enormously. A credential on a business card does not tell you whether a broker can sell your specific type of business in your specific market. Here is how to evaluate them.
**Ask for closed transaction history in your industry.** Not just 'experience with service businesses' — ask for the last 5–10 businesses they sold that are comparable to yours in industry, size, and geography. A broker who has sold 8 HVAC companies in the last two years understands buyer expectations, typical multiples, and deal-specific diligence issues in a way a generalist does not. A broker who has never sold a business like yours is learning on your deal.
**Verify their buyer database.** Ask how many buyers are in their database, how recently those buyers were active, and how many of them have liquid assets in the range of your deal. A database of 10,000 buyers that is 5 years old and has never been segmented is worth less than a curated list of 300 active buyers who have made offers in the last 18 months.
**Interview at least three brokers before signing.** Most sellers sign with the first broker who gives them an impressive presentation. The brokers who win listing agreements with the highest proposed asking prices are not always the ones who close at the highest prices — some deliberately quote high to win the listing and reduce expectations later. Get multiple opinions on valuation and push back on any number that seems inflated relative to what comparable businesses have sold for.
**Check references from sellers, not buyers.** Ask for contact information for two or three sellers whose businesses the broker sold in the last 12 months. Call them. Ask how long the process took, whether the final price matched the initial estimate, how responsive the broker was during due diligence, and whether they would use the broker again.
**Understand what happens if the broker underperforms.** Most listing agreements have no performance provisions — the broker has 12 months of exclusivity regardless of activity level. Negotiate a minimum activity clause: a defined number of qualified buyer introductions within 60–90 days, or the right to terminate without a tail clause. A broker who is confident in their ability to perform will agree to reasonable activity benchmarks.

Before you meet with brokers, know your own number. If a broker's proposed asking price is significantly higher than your EBITDA supports, they're pitching you — not pricing you.

Here is what the process looks like once you sign a listing agreement with a qualified broker.
**Weeks 1–3: Business packaging.** Your broker will interview you about the business, review your financials, and prepare the CIM. This document is the backbone of your sale — a well-written CIM converts buyer interest into offers. Review it carefully before it goes out. Correct factual errors immediately. Confirm that the adjusted earnings summary matches your own calculations.
**Weeks 2–6: Marketing and initial inquiries.** The broker lists your business across platforms and reaches out to their buyer database. Expect a burst of inquiries in the first two weeks followed by a slower steady flow. Most early inquiries are tire-kickers. Your broker's job is to screen them so you are not spending time on people who cannot close.
**Weeks 4–12: Qualified buyer conversations.** After NDA and financial verification, qualified buyers receive the CIM and request introductory calls. You will typically speak with 3–8 serious buyers over this period depending on your industry and price point. Some businesses sell in the first 60 days. Most take 3–6 months from listing to LOI.
**LOI to close: 60–90 days.** Once a buyer submits a Letter of Intent and you negotiate and sign it, the exclusivity clock starts. Due diligence runs 30–60 days, during which the buyer reviews your financials, operations, contracts, and assets in detail. After due diligence, purchase agreement negotiation runs 2–4 weeks, followed by closing. For deals with SBA financing, the lender's underwriting timeline runs in parallel and typically takes 45–60 days from LOI to funding.
Know what your deal looks like from a financing perspective before you get into this process. The SBA Loan Calculator shows you exactly what monthly debt service your asking price produces at current rates — if the numbers don't work for an SBA buyer, you'll either need seller financing, a higher EBITDA, or a different buyer type.

Know if your asking price is SBA-financeable before your first buyer conversation. A price that doesn't cash flow at current rates will die at the financing contingency.

Signing a listing agreement is not the end of your involvement — it is the beginning of a working relationship that requires active management on your side.
**Be responsive.** The most common complaint buyers have about brokered deals is slow response times from the seller side. A buyer who asks a question on Tuesday and gets an answer the following Monday loses momentum. Every day a buyer is not moving forward is a day they might look at another deal. Set a target of 24-hour response time to any broker or buyer request during the active marketing phase.
**Give your broker the full picture.** Brokers can only protect you from problems they know about. If there is a customer dispute in progress, a lease expiration coming up, or a key employee who has expressed interest in leaving, your broker needs to know. Surprises in due diligence are deal-killers. Disclosed issues are manageable issues.
**Stay off the market personally while under exclusivity.** Once you sign a listing agreement, do not have parallel conversations with potential buyers through other channels unless your agreement explicitly permits it. If a competitor calls out of the blue and asks if you'd consider selling, tell your broker immediately — do not handle it yourself. Parallel conversations create legal and commission disputes that delay closings.
**Push for activity reporting.** Ask your broker for a weekly update: how many inquiries received, how many NDAs sent and signed, how many buyer conversations in progress. A broker who can't produce basic activity data is a broker who is not working your listing hard enough. These conversations should happen proactively — you should not be chasing your broker for status updates.
When an offer comes in, have the LOI Generator ready so you can review what a clean LOI should look like and spot any unusual terms in what the buyer has submitted. The LOI is where price, deal structure, exclusivity, and due diligence timeline get set — understanding what each clause means before you sign it saves significant negotiating leverage later.

A broker is not always the right choice. Here are the scenarios where selling yourself makes more sense.
**Your business is under $400K.** At this price point, broker commissions consume 10–15% of your proceeds. The buyer pool is smaller and simpler to manage, the due diligence is less complex, and the process is manageable for a seller with reasonable organizational skills. The DIY business sale guide covers the full process.
**You have a clear strategic buyer in mind.** If a competitor, supplier, or someone in your industry has already expressed interest — or if you know exactly who the right buyer is — a broker adds friction and commission to a transaction that would happen anyway. Hire a transaction attorney and handle it directly.
**You have prior deal experience.** Sellers who have been through a business sale before — as buyer or seller — understand the process well enough to run it. The broker's process knowledge is most valuable to first-time sellers.
**Your business is hard to value or hard to explain.** Paradoxically, highly specialized businesses sometimes do better without brokers because no generalist broker understands the industry well enough to represent it credibly. A specialized M&A advisor or investment banker with deep sector expertise is a better choice than a generalist business broker in these cases.
For industry-specific context on what buyers expect, what multiples look like, and how deals close in specific sectors — including HVAC, landscaping, dental practices, and pest control — the acquisition guides cover the buyer perspective in detail, which helps you understand what a broker should be telling buyers about your business.
A great broker earns their commission. A mediocre one collects it. The difference is knowable before you sign — check their transaction history in your industry, verify their buyer database, and call their references. Once you're under listing agreement, treat the broker relationship as a partnership that requires your active participation, not a service you pay for and wait on. The sellers who close fastest are the ones who show up prepared, respond fast, and make their broker's job easy.
