Owners hear both terms used almost interchangeably, and the businesses that sell them rarely go out of their way to explain the difference. It matters more than the terminology suggests. A broker and an M&A advisor are built around two different models of how a sale actually happens, and which one you use shapes your price, your confidentiality, and how much of the negotiation actually goes your way.
The Broker Model: List and Wait
A business broker typically works the way a residential real estate agent does: the business gets listed, often on a public or semi-public marketplace, marketing materials go out, and the broker waits for interested buyers to inquire. It's a volume model built for speed and simplicity, and for a lot of smaller, simpler businesses, that's a reasonable fit. Commission is usually a flat percentage of sale price, in the 10–12% range, regardless of how complex the transaction turns out to be.
What the broker model doesn't typically include: a targeted search for the specific buyers most likely to value your business highest, deep negotiation on deal structure beyond price, or management of a multi-stage confidential process.
The Advisor Model: Build and Compete
An M&A advisor starts from the opposite direction. Instead of listing the business and waiting, we build a curated list of buyers, strategic acquirers, private equity firms, and qualified individuals, who are specifically likely to value this business, then run a structured, confidential process to create competitive tension among them. Our post on finding the right buyer covers how that list actually gets built.
The negotiation goes well past headline price: working capital targets, earnout structure, representations and warranties, transition terms. Our post on LOI gotcha clauses covers exactly the kind of detail a listing-based process is less equipped to catch.
The short version:
Broker — lists the business, waits for interest, flat commission, works well for simpler main-street transactions.
M&A advisor — builds a targeted buyer list, runs a competitive confidential process, negotiates structure as hard as price, built for larger and more complex transactions.
Confidentiality: Public Listing vs. Controlled Process
Broker listings are frequently posted to marketplaces that anyone, including your competitors, employees, and customers, can browse. An advisor-run process is typically built the other way around: a blind teaser with no identifying detail, buyer vetting before anything sensitive is shared, and a signed NDA before your name or financials ever go anywhere. See exactly how that works in a Blackland engagement.
The highest bidder from a public listing and the right buyer from a competitive, confidential process are not always the same buyer. Price is only one term in a deal that includes a dozen others.
Where the Line Actually Blurs
There's no regulatory line that separates "broker" from "M&A advisor," and plenty of firms use the titles loosely. The more useful question isn't which label someone uses, it's what process they actually run: do they identify and approach specific buyers, or wait for inquiries? Do they negotiate structure, or just the number at the top of the page? Do they manage a genuinely confidential process, or a public listing? Ask those three questions of any advisor you're evaluating, broker-titled or not.
Size is a reasonable proxy, though an imperfect one. Below roughly $10MM in revenue, the broker model's simplicity and speed are often a fair trade for a business that doesn't need an elaborate competitive process. Above that range, and especially into the $10–$100MM lower middle market, the complexity of the business and the sophistication of likely buyers usually make a targeted, advisor-run process worth the additional rigor.
Cost: Not as Different as You'd Expect
A flat 10–12% broker commission can look cheaper on paper than an advisor's fee structure, but the comparison rarely holds up once deal size and outcome are factored in. Advisor fees typically scale down as transaction value increases, and a competitive process built to generate real buyer tension often produces a materially higher sale price, meaning the higher percentage on paper can still net a better outcome in dollars. Our post on how Blackland Advisors' fees work breaks down the full structure.
The right question isn't broker or advisor. It's whether the process someone's proposing actually fits the business you've built.
