What Is a Business Broker? Do You Need One?

When business owners start thinking about selling, one of the first questions I hear is: "Do I need a broker?" The answer is almost always "it depends" — which I realize is unhelpful, so let me give you the full picture.

I've worked alongside dozens of business brokers over the years. Some are exceptional professionals who earn every dollar of their fee. Others are part-time operators who list businesses like real estate agents list houses and hope for the best. Knowing the difference — and whether you need one at all — can save you tens of thousands of dollars or make you hundreds of thousands more.

What a Business Broker Actually Does

A business broker is an intermediary who helps business owners sell their companies. Think of them as the real estate agent of the business world, but with significantly more complexity and higher stakes.

A good broker handles every phase of the transaction:

• Valuation: Providing a market-based opinion of value (not an appraisal — important legal distinction).
• Marketing: Creating a blind profile, listing on BizBuySell and similar platforms, reaching out to their buyer database, advertising the opportunity without revealing your identity.
• Screening buyers: Qualifying inquiries, requiring NDAs, verifying proof of funds before sharing your financials. This alone justifies a broker for many sellers.
• Facilitating negotiations: Serving as a buffer between you and the buyer so emotions don't derail the deal.
• Managing due diligence: Coordinating document requests, keeping the process on track, pushing both sides toward closing.
• Coordinating closing: Working with attorneys, lenders, accountants, and landlords to get everything to the finish line.

The part that most sellers underestimate is confidentiality management. Once word gets out that your business is for sale, employees panic, customers look elsewhere, and competitors smell blood. A broker maintains confidentiality by marketing the business anonymously and controlling information flow. If you try to sell on your own, keeping the secret becomes exponentially harder.

Business Broker vs M&A Advisor vs Investment Banker

These terms get used interchangeably, but they represent meaningfully different services at different price points for different deal sizes.

Business brokers typically handle deals from $200K to $5M. They work on a success-fee basis (paid at closing), often list on public marketplaces, and may handle 10-20 active listings simultaneously. Many operate as sole practitioners or small firms. The IBBA (International Business Brokers Association) is the primary credentialing body, offering the CBI (Certified Business Intermediary) designation.

M&A advisors(sometimes called "intermediaries") operate in the $5M-$100M range. They run structured sale processes — creating a confidential information memorandum (CIM), building a targeted buyer list, soliciting competing offers, and negotiating terms. They typically carry fewer engagements (3-5 at a time) and invest significantly more time per deal.

Investment bankers handle deals above $100M. They run formal auction processes, provide fairness opinions, and employ teams of analysts. Think Goldman Sachs, not Main Street.

The lines blur in the middle market. An M&A advisory firm might handle a $3M deal if they have a strong buyer relationship, and a sophisticated broker might run a perfectly professional process on a $10M business. What matters more than the title is the specific experience of the person handling your deal.

Fee Structures: What You'll Pay

Business broker fees follow a standard structure, but the specifics vary more than most sellers realize. Here's what I see across the market:

Success fee (commission):The primary compensation model. Rates typically range from 8-12% for businesses under $1M, dropping to 6-10% for businesses between $1M-$5M. The fee is paid only at closing, from the seller's proceeds.

Let me put real numbers on this. On a $750,000 sale at 10%, the broker earns $75,000. On a $2.5M sale at 8%, it's $200,000. On a $5M sale at 6%, it's $300,000. These are meaningful numbers — and they should motivate your broker to get the deal done at the highest possible price.

The Lehman Formulais common for larger deals: 5% on the first $1M, 4% on the next $1M, 3% on the next $1M, 2% on the next $1M, and 1% thereafter. A $5M deal under Lehman yields a $150,000 fee. Many modern M&A advisors use a "double Lehman" or "modified Lehman" that starts at 10% on the first million.

Upfront retainer: Some brokers charge $5,000-$15,000 upfront to cover initial valuation work and marketing preparation. This is increasingly common and, frankly, often a sign of a more serious broker. The retainer is typically credited against the success fee at closing. Be cautious of brokers who charge large upfront fees with no success-fee credit — they may make their money whether your business sells or not.

Minimum fee:Most brokers have a floor, typically $20,000-$50,000. If your business sells for $150,000, a 10% commission ($15,000) may not be worth the broker's time, so the minimum kicks in.

How to Vet a Business Broker

The barrier to entry in business brokerage is shockingly low. In most states, you need a real estate license (or nothing at all) to call yourself a business broker. That means the range of competence is enormous. Here's how I'd evaluate one:

Track record in your industry. A broker who has sold 30 HVAC companies knows the buyer universe, the typical multiples, and the deal structures that work. A generalist broker handling their first HVAC deal is learning on your dime. Ask for a list of closed transactions in your specific industry.

Credentials.The CBI (Certified Business Intermediary) from the IBBA requires coursework, exam passage, and closed transaction experience. The M&AMI (M&A Master Intermediary) is the next level up. These don't guarantee competence, but they indicate someone who takes the profession seriously.

Deal size alignment. A broker who typically handles $5M+ deals may not give adequate attention to your $800K business. Conversely, a broker whose largest deal was $600K might be in over their head with your $3M company. Ask about their typical deal size range.

Closing rate.This is the number most brokers don't want to share. The industry average is roughly 20-25% — meaning 75-80% of listed businesses never sell. A broker with a 40%+ closing rate is either very selective about listings (good) or very good at getting deals done (also good). Either way, that's who you want.

References from sellers, not buyers. Any broker can find a happy buyer. You want to talk to sellers — ideally ones whose deals closed and ones whose listings expired. Both conversations are revealing.

When You Do NOT Need a Broker

There are legitimate situations where hiring a broker is a waste of money:

The business is very small (under $200K).At this price point, broker fees consume a disproportionate share of proceeds. A $150K business at a $25K minimum fee means you're paying 16.7% in brokerage alone. For businesses this small, you may be better off listing on BizBuySell yourself and hiring an attorney to handle the closing for $3,000-$5,000.

You already have a buyer. If a competitor, employee, or family member wants to buy the business, a broker adds cost without adding value. You still need an M&A attorney and probably a third-party valuation, but not a broker.

You're selling to private equity or a known strategic buyer. If a PE firm approaches you directly, they have their own process. You need a good M&A attorney and potentially a sell-side financial advisor, but not a traditional business broker.

The Dual Agency Problem

Here's something that surprises most sellers: in many states, the same broker can represent both buyer and seller. This is called dual agency, and it creates an inherent conflict of interest. Your broker is supposed to maximize your sale price, but they also have a financial relationship with the buyer — and they get paid only if the deal closes.

In practice, I've seen dual agency situations where the broker pressured the seller to accept a lower offer because the buyer was "ready to close quickly." The broker's motivation was clear: a guaranteed smaller commission now versus a potential larger commission later (or never).

Ask your broker upfront: "Will you represent only me in this transaction?" Get it in writing. If they bring a buyer from their own network, clarify who they represent and how compensation works.

Red Flags to Watch For

• Inflated valuation to win the listing: If one broker says your business is worth $2M and three others say $1.2M-$1.4M, the outlier is telling you what you want to hear. Overpriced businesses sit on the market and go stale.
• Exclusive listing with no performance clause: A 12-month exclusive agreement with no right to terminate if the broker fails to produce qualified buyers is a trap. Insist on a 6-month term with a 90-day cancellation clause after 60 days of no buyer activity.
• Large upfront fees with no accountability: $10,000+ upfront with no credit toward closing and no deliverables tied to the fee is a warning sign.
• No written marketing plan: If the broker can't articulate exactly how they'll market your business — which platforms, which buyer databases, what outreach strategy — they're winging it.
• "I have a buyer ready right now": The oldest trick in the brokerage playbook. If they really had a ready buyer, they wouldn't need your listing.

The Bottom Line

For most business owners selling a company worth $500K-$5M, a good broker is worth the fee. They maintain confidentiality, bring qualified buyers you'd never find on your own, and handle the hundreds of hours of work that go into getting a deal closed. The key word is "good." A bad broker can cost you more than their fee — through overpricing, poor marketing, broken confidentiality, or simply wasting 12 months of your time.

Do your due diligence on the broker the same way a buyer will do due diligence on your business. Check credentials, verify track record, call references, and negotiate terms that protect your interests. The right broker relationship is a partnership, not a listing agreement.
