Hiring the wrong business broker is one of the costliest mistakes a seller can make. A bad broker overprices your business, fails to generate qualified buyer interest, and then pressures you to drop your price six months later after the listing has gone stale. A good broker earns their commission multiple times over. Knowing what separates the two takes some preparation before you start making calls.

Where to Find Business Brokers

Start with professional directories rather than Google searches. The best sources for finding qualified brokers include:

• IBBA Directory: The International Business Brokers Association (IBBA) maintains a searchable directory of member brokers. IBBA members have agreed to a code of ethics and many hold the Certified Business Intermediary (CBI) designation, which requires continuing education and demonstrated transaction experience.
• M&A Source: For deals in the $1 million to $50 million range, the M&A Source directory lists merger and acquisition advisors who specialize in larger transactions.
• BizBuySell Broker Directory: The largest business-for-sale marketplace also lists brokers by region and specialty. You can see how many active listings each broker carries.
• Referrals from advisors: Your CPA, attorney, or financial advisor has likely worked with brokers on other transactions. A warm referral from a trusted professional is often better than any directory listing.

The Interview: Questions That Reveal Competence

Interview at least three brokers before signing anything. The conversations will be illuminating: competent brokers answer questions directly and specifically, while weak ones give vague answers and pivot to their own sales pitch. Here are the questions that matter:

What is your experience in my industry?

A broker who has sold five HVAC businesses knows the buyer pool, the standard multiples, and the deal structures that work in that space. A generalist who has mostly sold restaurants and retail stores will have to learn your industry on your dime. Industry experience is not mandatory, but it matters more as your business gets larger and more specialized.

How many deals did you close in the last 12 months?

Volume is a proxy for activity and market knowledge. A broker closing five to ten deals per year is actively working. Someone who closed one deal last year may be a part-time operator or struggling in the current market. Ask for the actual number, not a vague “quite a few.”

Can you provide references from recent sellers?

Any broker worth hiring should be able to provide two or three seller references from the last 12 to 18 months. Call them. Ask how the broker managed the process, whether the final price matched the initial estimate, and whether they would use the same broker again.

How do you value a business?

This question separates professionals from amateurs. A qualified broker should explain SDE or EBITDA multiples, discuss comparable sales in your industry, and walk you through the add-backs they would include. If they cannot answer this clearly, they are not qualified to price your business. For more context on how valuations work, read our guide: How to Value Your Business Before Selling.

How do you market a business for sale?

Strong brokers use a combination of blind listings on multiple platforms, targeted outreach to their buyer database, and direct marketing to strategic buyers in your industry. Weak brokers post one listing on BizBuySell and wait. Ask specifically what platforms they use, how many active buyers are in their database, and whether they pursue strategic buyers proactively.

What is your commission structure and listing agreement length?

Most broker commissions on small businesses range from 8% to 12%, sometimes with a minimum fee of $10,000 to $20,000. Larger deals typically use a tiered structure called the Lehman formula or a modified version of it. Listing agreements typically run six to twelve months. Be wary of agreements longer than twelve months without an early termination clause if performance benchmarks are not met.

Red Flags to Walk Away From

Not all brokers are operating at the same level of professionalism. Here are warning signs that should make you keep looking:

• They quote you a high price immediately: A broker who tells you your business is worth significantly more than others without doing any financial analysis is trying to win the listing by flattering you. This is called “buying the listing,” and it leads to overpriced businesses that sit on the market and go stale. Stale listings sell for less, not more.
• They want an upfront fee to list your business: Reputable brokers work on commission, paid only at closing. Brokers who charge upfront “marketing fees” or “valuation fees” before the sale are structured differently and the incentive alignment is off.
• They cannot give you recent comparable sales data: Pricing a business requires knowing what similar businesses have sold for recently. If a broker cannot produce real comps, they are guessing.
• They are vague about their buyer database: “I have a large network” is not an answer. Ask how many active buyers are in their database, how recently those buyers were contacted, and what their pre-qualification process looks like.
• They push you to sign without reviewing the listing agreement carefully: Read the entire listing agreement before signing. Pay particular attention to the tail clause, which determines whether you owe a commission if you sell to someone you met through the broker after the agreement expires.

Broker Credentials Worth Knowing

Professional credentials are not guarantees, but they signal a minimum level of commitment to the field:

• CBI (Certified Business Intermediary): Awarded by the IBBA. Requires passing an exam, completing continuing education, and demonstrating transaction experience. This is the primary credential for main street business brokers.
• M&A Master Intermediary (M&AMI): An advanced credential from M&A Source for intermediaries who specialize in the middle market.
• CM&AP (Certified Mergers and Acquisitions Professional): Offered by the Alliance of Merger and Acquisition Advisors (AM&AA), focused on larger transactions.

Not every excellent broker holds one of these designations, and not every credentialed broker is excellent. But these certifications do indicate genuine engagement with the profession.

How to Evaluate the Listing Agreement

Before you sign with a broker, review these specific terms in the listing agreement:

• Commission rate and minimum fee: Understand exactly what you owe at closing and under what circumstances.
• Exclusivity: Most listing agreements are exclusive, meaning you cannot use another broker simultaneously. This is standard and acceptable.
• Agreement length: Six to twelve months is typical. Negotiate a performance clause if the term is longer than six months.
• Tail clause: If a buyer is introduced by the broker during the listing period and later approaches you directly after the agreement expires, you may still owe a commission. Typical tail periods run six to twenty-four months.
• Marketing obligations: Get a clear description of exactly where and how your business will be marketed. Vague language is a red flag.

One Final Point on Timing

The best time to interview brokers is before you are in a rush to sell. Sellers who are desperate, due to health issues, financial pressure, or partnership disputes, are easier to take advantage of. Go through this process while you still have options. Understanding how long the sale process typically takes helps set the right expectations: see our full breakdown at How Long Does It Take to Sell a Business? A Realistic Timeline.

A well-chosen broker is one of the most important professionals on your sale team. Take the time to find the right one, and the rest of the process becomes significantly smoother.
