A business broker commission is usually the largest cost of selling a company through an intermediary, so it pays to understand it before you sign anything. The percentage matters, but so do the minimums, the contract length, and what the broker actually does for you.
How a business broker commission is usually structured
Most brokers charge a success fee, which is a percentage of the final sale price paid at closing. Some also charge an upfront or monthly fee to cover marketing and valuation work, which is paid whether or not the business sells.
Percentages vary by region, industry, and deal size. Smaller deals often carry a higher percentage and a minimum fee, while larger deals may use a lower rate or a sliding scale.
Common fee models
Ask the broker to explain exactly which model they use and to put it in writing. The same headline percentage can cost very different amounts depending on how it is applied.
- A flat percentage of the final price
- A tiered or sliding scale that lowers the rate as the price rises
- A minimum fee that applies to small sales
- An upfront retainer or marketing fee
- A monthly fee while the business is listed
Extra costs to ask about
A business broker commission is rarely the only cost. You may also pay for a formal valuation, professional photos, legal review, accounting help, and advertising. Ask which of these the broker covers and which you pay separately.
Also ask whether the commission applies to the whole transaction, including inventory, real estate, and any seller financing or earnout payments.
The listing agreement matters as much as the rate
Most brokers ask for an exclusive listing for several months, and many include a tail period that lets them collect a fee if you sell to someone they introduced after the agreement ends. Read the term length, the cancellation rights, and the tail language closely.
A lower business broker commission can be a poor deal if the broker does little marketing, so ask for a written description of services, how buyers are screened, and how often you will receive updates.
Judge value, not just price
A strong broker prices the business realistically, keeps the sale confidential, qualifies buyers, and helps manage due diligence and negotiation. Ask for references from recent sellers and for the broker’s record of closed deals in your size range. Our guide to working with a business broker explains how to find one and what to expect.
Negotiating your business broker commission
Most brokers will explain their fees, and some will adjust them for strong listings or exclusive terms. Compare at least two or three proposals, ask for sample agreements, and have your attorney review the final version before you sign. A clear business broker commission agreement protects both sides.
