What's the difference between a business broker and an M&A advisor?
Business brokers typically handle transactions under $5 million — often called Main Street businesses — while M&A advisors typically work on deals above $5 million in the lower middle market and middle market segments.
Primary Distinction: Deal Size and Transaction Complexity
The $5 million threshold is the practical dividing line. Business brokers commonly work with owner-operators selling retail stores, restaurants, service businesses, and small manufacturing operations. M&A advisors typically work with established companies that have professional management teams, audited financials, and institutional buyer appeal.
Both types of engagements typically last 6–12 months from engagement to closing.
Fee Structure Differences
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). The fee is usually success-based — paid only when the deal closes.
M&A advisors usually charge a work fee during the engagement plus a success fee at closing. 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).
Scope of Services
Business brokers focus primarily on marketing the business, managing buyer inquiries, and facilitating negotiations between a single seller and prospective buyers. The engagement centers on finding a qualified buyer and closing the transaction.
M&A advisors provide comprehensive transaction services including valuation analysis, buyer identification and qualification, deal structuring, due diligence coordination, and complex negotiation support. The engagement typically involves managing a competitive process with multiple potential buyers and addressing sophisticated tax and legal structuring questions.
Regulatory and Professional Designations
In Canada, business brokers are not uniformly required to hold a real estate license — a real estate license is required only when the transaction includes real property.
M&A advisors in Canada are not uniformly regulated and do not require a specific professional license, though many hold designations such as CFA, CBV, or CPA. The M&A Source and Alliance of Merger & Acquisition Advisors are primary professional associations for M&A advisors.
When to Work With Each Type
If you are selling a business valued under $5 million — a restaurant, retail store, or service business where you are the primary operator — a business broker is typically the right fit. The commission-based model aligns incentives without requiring upfront capital, and the broker's focus on marketing and buyer management matches the transaction's scope.
If you are selling a business valued above $5 million with professional management, audited financials, and potential appeal to strategic or financial buyers, an M&A advisor is typically the appropriate choice. The monthly retainer reflects the depth of work required to run a competitive process, and the advisor's experience with complex deal structures and institutional buyers becomes material to outcome.
