Business Broker
A business broker is a professional intermediary who facilitates the sale of privately held businesses, typically those with annual revenues between $500,000 and $50 million. The broker represents the seller in most transactions: marketing the business confidentially, screening buyers, managing negotiations, and coordinating the advisors and documents required to close. The standard compensation is a success fee, most commonly 10 percent of the sale price for smaller transactions, paid only when the deal closes.
What a business broker does
Selling a business is a different transaction from selling a house or a piece of equipment. The business itself is often the seller’s largest asset, and the sale must be conducted in secrecy. If employees learn that the company is on the market, key people may leave. If customers or suppliers find out, they may reduce their exposure before the deal is done. A broker manages this complexity across eight core functions [1] [2].
Valuation. Before marketing begins, the broker produces an opinion of value to help the owner set a realistic asking price. The three methods the U.S. Small Business Administration identifies are the income approach (based on projected revenue and risk), the market approach (comparing similar businesses that have sold), and the asset approach (net asset value after liabilities) [1]. Most business sales rely primarily on an income or market approach, with the EBITDA multiple being the dominant benchmark for ongoing businesses.
Confidential marketing. The broker writes a blind profile, a one-page teaser that describes the business by industry and financial profile without naming it, and distributes it to a database of qualified buyers. Buyers who express interest sign a non-disclosure agreement before receiving the full confidential information memorandum (CIM) with the company name and complete financials.
Buyer qualification. Many people who inquire about acquiring a business are not in a position to close. The broker screens for financial capability, relevant experience, and genuine intent before introducing a buyer to the seller, protecting the seller’s time and the deal’s confidentiality [2] [3].
Negotiation support. The broker helps structure the offer and manages the back-and-forth on price, terms, earnouts, seller financing, and conditions. Most sellers are doing this for the first or only time. The broker has completed many transactions and understands where deals break down and how to bridge gaps between buyer and seller expectations [3].
Due diligence coordination. After a letter of intent is signed, the buyer’s team will examine financial records, customer contracts, leases, and operating systems. The broker manages the data room, tracks open items, and keeps the process moving toward the scheduled close date.
Closing coordination. The broker works with the attorneys, accountants, lenders, and landlord to get the purchase agreement signed and the funds transferred.
How brokers are paid
Business brokers work primarily on a success fee, which means no payment is due unless the business sells. This aligns the broker’s financial interest with the seller’s: both want the highest possible sale price at close [2] [4].
The standard fee for main street transactions, typically those with a sale price below $1 million, is 10 percent of the total purchase price. Some brokers use a minimum fee of $10,000 to $15,000 on very small deals to cover the work involved regardless of price. For transactions above $1 million, fees often follow a modified version of the Lehman formula: a declining percentage applied to successive increments of the total price. The result is a lower effective rate for larger transactions but a larger absolute fee [4].
A smaller number of brokers charge a combination of an upfront retainer and a reduced success fee. The retainer compensates the broker for valuation and marketing work if the business does not sell. Sellers should clarify the complete fee structure before signing a listing agreement and confirm whether the retainer is applied against the success fee or is a separate charge.
The International Business Brokers Association’s Market Pulse survey tracks reported transaction data by deal size and industry and publishes median fee structures as part of its quarterly findings [5].
Business broker vs. M&A advisor vs. investment banker
Three categories of professional facilitate private company sales, and the right choice depends almost entirely on deal size [6] [7].
| Type | Typical deal size | Fee structure | Key credential |
|---|---|---|---|
| Business broker | $250K – $10M enterprise value | 10% success fee (main street) or modified Lehman | CBI (Certified Business Intermediary) from IBBA |
| M&A advisor / intermediary | $5M – $50M enterprise value | 5–8% success fee, sometimes with retainer | M&A Source designation or investment banking background |
| Investment banker | $50M+ | Retainer plus 2–5% success fee (Lehman or double-Lehman) | FINRA Series 79 or 7 license |
The boundary between business brokers and M&A advisors is not fixed. Some business brokerage firms work on transactions up to $25 million, and some intermediaries describe themselves as M&A advisors for deals well below that threshold. The M&A Source, a division of the International Business Brokers Association focused on the lower middle market, offers its own education and designation for professionals working in the $5 million to $50 million range [7].
The CBI designation
The most widely recognized credential in the business brokerage profession is the Certified Business Intermediary (CBI), awarded by the International Business Brokers Association (IBBA). The IBBA was founded in 1984 and is the largest international non-profit association operating exclusively for business brokerage professionals [3].
Earning a CBI requires completing a prescribed education curriculum through IBBA’s courses, passing a proctored exam, and meeting minimum transaction experience requirements. The IBBA also awards the Master Certified Business Intermediary (MCBI) designation for brokers who have completed additional education and closed a larger volume of transactions [3].
Not every qualified broker holds a CBI, but the designation signals a formal commitment to education and ethics in a profession that does not require a federal license to practice. Licensing requirements vary by state, with some states requiring a real estate license to act as a business broker and others having no specific licensing requirement at all.
How to find and vet a broker
The IBBA maintains a directory of member brokers searchable by location and industry specialty at ibba.org [4]. Searching for brokers with a CBI designation filters for those who have met the association’s formal education and experience standards.
Beyond credentials, the right questions to ask a prospective broker before signing a listing agreement are: how many businesses in this size range and industry have you closed in the past 24 months, what is your current number of active listings, how will you market confidentially without identifying the business, who covers client communication when you are unavailable, and what is your fee structure including any retainer. A broker with too many active listings may not have time to find a buyer for one more. A broker with too few closed transactions may not have the buyer network to generate qualified offers [4] [5].
Sellers should interview two or three brokers before committing to an exclusive listing agreement. The listing agreement is a binding contract and most give the broker the right to a commission if they introduced the eventual buyer, even if the seller terminates the agreement before the deal closes.
The listing agreement
The listing agreement is the contract between the seller and the broker that defines the terms of the engagement. Key provisions include the duration (typically six to twelve months with an option to renew), the exclusivity clause (most agreements are exclusive, meaning only the listing broker has the right to represent the seller), the fee percentage and structure, and the tail period, which is the window after the agreement ends during which the broker still earns a fee if a buyer they introduced completes the purchase [2].
Sellers should pay close attention to the tail period. A twelve-month tail means that if the broker introduced a buyer in month eight of the listing and the listing expires without a close, the seller still owes the fee if that buyer purchases the business within twelve months of the listing termination. Tail periods of six to twenty-four months are common.
Confidentiality is the broker’s first job
The most important skill a business broker brings to a sale is not valuation or negotiation. It is managing confidentiality. A business that becomes known in its local market as being for sale faces real damage: key employees begin exploring alternatives, suppliers tighten terms, customers reduce orders. Skilled brokers run controlled processes where no one learns the company’s name until after signing an NDA, and even then, information is released in stages. The seller should ask every prospective broker specifically how they intend to market the business without tipping off employees, customers, competitors, and suppliers. The answer to this question reveals more about the broker’s process discipline than any credential [2] [3].
A worked example
ILLUSTRATIVE COMPOSITE An owner of a regional payroll services company with $3.2 million in revenue and $640,000 in EBITDA decided to sell. She approached two brokers. The first proposed a six-month exclusive listing at 8 percent of the sale price, planned to list the company on three public business-for-sale marketplaces, and estimated a sale price of $2 million. The second, a CBI with 12 closings in professional services in the prior two years, proposed a twelve-month exclusive at 10 percent, planned to approach 40 strategic acquirers privately with a blind profile, and estimated a sale price of $3.2 million to $3.8 million based on comparable transactions in the M&A Source data for her industry and deal size. She signed with the second broker. Six months later, she accepted a $3.5 million offer from a regional accounting firm that was expanding into payroll. Public listings had produced four inquiries. The private outreach campaign produced fourteen qualified conversations. The higher fee produced a better outcome because the broker’s process produced better buyers, and better buyers pay more [5] [7].
When a broker makes sense
For most business owners, a qualified broker produces better outcomes than attempting to sell independently. The IBBA Market Pulse data consistently shows that businesses sold with professional representation close at higher multiples and in shorter time than comparable FSBO (for sale by owner) transactions [5].
A broker is most valuable when the seller lacks a ready, pre-identified buyer, when the business is in a sector or size range where the broker has active relationships with qualified acquirers, when the seller is still actively running the business and cannot spend time qualifying buyers and managing due diligence, and when the transaction involves complexity such as real estate, earnouts, seller financing, or multiple owners [1] [2].
Seller financing, where the seller accepts a note for part of the purchase price rather than all cash at close, is common in small business sales and affects the broker’s fee calculation. Most listing agreements define how the success fee is calculated when the purchase price includes a seller note. Confirming this in writing before signing prevents disputes at close.
A broker adds less value when the seller already has a specific buyer identified, when the transaction is a family transfer or employee buyout where confidential marketing is not needed, or when the deal is large enough to warrant a full investment banking engagement with a formal auction process. For those situations, the right intermediary is an M&A advisor or banker with the resources to run a structured process among multiple financial and strategic acquirers simultaneously [7] [8].
