Selling a Business

Business Broker vs. M&A Advisor: Which Do You Need to Sell Your Business?

By Irongate Markets · June 28, 2026 · 7 min read

When a business owner decides to sell, one of the first questions they face is: should I hire a business broker or an M&A advisor? The titles sound similar, but the two professionals serve very different markets, run very different processes, and produce very different outcomes. Choosing the wrong one for your deal size can cost you hundreds of thousands — or millions — of dollars in sale price.

Here's a plain-English breakdown of the difference, what each charges, and how to decide which is right for your situation.

The Core Difference: Deal Size and Process

The simplest way to understand the distinction: business brokers handle public listings for smaller businesses, M&A advisors run confidential competitive processes for larger ones.

🏪 Business Broker

  • Deals: $100K–$3M asking price
  • Lists business publicly (BizBuySell, etc.)
  • Reactive — waits for buyer inquiries
  • Lower fee (8–12% of sale price)
  • Faster, simpler process
  • Less negotiating leverage

🏦 M&A Advisor

  • Deals: $2M–$250M+ enterprise value
  • Confidential — no public listing
  • Proactive — runs structured buyer outreach
  • Retainer + success fee (5–10%)
  • Longer, more complex process
  • Creates competitive tension = higher price

What Does a Business Broker Do?

A business broker helps owners sell smaller businesses — typically main street companies like restaurants, retail stores, service businesses, and small contractors with revenues under $5M.

  1. Value the business using an income or market approach
  2. Prepare a basic listing package (asking price, financials summary, business overview)
  3. List the business on public marketplaces (BizBuySell, BusinessBroker.net, LoopNet)
  4. Field buyer inquiries and screen for financial capability
  5. Facilitate the purchase agreement and coordinate closing

The key limitation: because the listing is public, anyone — including your employees, customers, suppliers, and competitors — can see your business is for sale. For businesses with $2M+ in EBITDA where confidentiality matters, a public listing is dangerous.

What Does an M&A Advisor Do?

An M&A advisor manages a confidential, structured sale process for businesses with $2M–$25M in EBITDA:

  1. Preparation: Advisor prepares a Confidential Information Memorandum (CIM)
  2. Buyer identification: Advisor builds a targeted buyer list — PE firms, independent sponsors, family offices, and strategic acquirers
  3. Controlled outreach: Buyers receive a blind teaser and must sign an NDA before getting any deal information
  4. Process management: Advisor runs a structured process creating competitive tension among multiple buyers
  5. Negotiation: Advisor negotiates price, structure, representations and warranties, earnouts, and seller note terms
  6. Due diligence support: Advisor manages the data room
  7. Closing: Advisor works with attorneys to get the purchase agreement across the finish line

Why the process matters: A competitive sale process consistently produces 20–40% higher valuations than a one-buyer negotiation. That difference far outweighs the advisor's success fee.

Fees: What Do Brokers and M&A Advisors Charge?

How to Choose: The Decision Framework

How to Find the Right M&A Advisor for Your Deal

Not all M&A advisors are equal. When evaluating advisors, ask: What is your average deal size? How many deals have you closed in my industry in the last 3 years? What is your buyer network? Can you show me a representative CIM from a recent deal?

The Bottom Line

Business brokers and M&A advisors both help owners sell their businesses — but they serve fundamentally different markets. If your business generates under $500K in EBITDA, a business broker is the right call. If your business generates $500K or more in EBITDA and you want maximum value, confidentiality, and a competitive process, you need an M&A advisor.
