What is the difference between a business broker and an M&A advisor?
Business brokers typically handle smaller transactions and are paid mainly by commission at closing, while M&A advisors work on larger deals, usually charge a work fee during the engagement plus a success fee, and provide more comprehensive transaction services. The primary distinctions are deal size, fee structure, and service scope.
Deal Size and Market Segments
Business brokers typically handle transactions under $5 million, commonly called Main Street businesses.
M&A advisors typically work on deals from $2 million to $100 million, covering the lower middle market and middle market segments.
Fee Structures and Compensation Models
The International Business Brokers Association (IBBA), a US-based association, says business broker commissions on Main Street sales can range from 8% to 15% of the final sale price and may be subject to an agreed minimum (IBBA, Your Guide to the Business Brokerage Profession, 2021).
In a 2024–25 survey of 456 middle-market advisors (about half in North America), the most common monthly work fee was $5,000 to $10,000, and the most common fixed engagement fee was also $5,000 to $10,000 (Firmex, Global M&A Fee Guide 2024-25). The most common success fees in the same survey were 4.8% on a $5 million deal, 3.4% on a $20 million deal and 2.0% on a $100 million deal, with North American fees somewhat higher than these global figures (Firmex, Global M&A Fee Guide 2024-25). Success fees are often structured using the Lehman Formula.
The classic Lehman Formula charges 5% of the first $1 million, 4% of the second million, and so on down to 1%; "Double Lehman" starts at 10% and falls to 2% (Firmex, Global M&A Fee Guide 2024-25).
Services and Transaction Complexity
Business brokers primarily list businesses for sale, market them to buyers, facilitate showings, and negotiate terms. Business broker engagements typically run 6–12 months from listing to close. Business brokers typically work with individual buyers or smaller private equity groups.
M&A advisors provide comprehensive services including business valuation, buyer identification and qualification, detailed financial packaging, deal structuring, due diligence coordination, and negotiation strategy. M&A advisor engagements for middle market deals typically span 9–18 months from engagement to close. M&A advisors often engage with strategic acquirers, family offices, and institutional buyers.
Licensing and Professional Standards
In Ontario, business brokers must hold a real estate broker license when the transaction includes real property. M&A advisors in Canada are not subject to uniform licensing requirements when transactions involve only share sales without real estate.
IBBA (International Business Brokers Association) and M&A Source are the primary professional associations for business brokers and M&A advisors in North America, with active Canadian membership. CBI (Certified Business Intermediary) designation is offered by IBBA for business brokers, while M&AMI (Mergers & Acquisitions Master Intermediary) is the advanced designation for M&A advisors.
When to Choose a Business Broker vs M&A Advisor
Choose a business broker when your business is valued under $5 million, operates as a single location or simple structure, and you prefer success-fee-only compensation. Business brokers are well-suited to retail, service businesses, and franchises where the buyer pool consists primarily of individual purchasers or first-time business owners.
Choose an M&A advisor when your business is valued above $2 million, has multiple locations or complex operations, requires sophisticated buyer qualification and deal structuring, or when you expect interest from strategic acquirers or institutional buyers. M&A advisors justify their higher upfront costs through more rigorous financial preparation, broader buyer outreach, and expertise in navigating complex due diligence and negotiation processes.
