Owners hear the two terms used almost interchangeably, and the firms offering these services rarely bother to explain the difference. The difference is real. A broker and an M&A advisor work from two different ideas of how a business gets sold, and the one you hire affects your price, your confidentiality and how much of the negotiation goes your way.
The Broker Model: List and Wait
A business broker usually 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 buyers to call. It's a volume model built for speed and simplicity, and it suits a lot of smaller, simpler businesses. Brokers also tend to price businesses on SDE rather than EBITDA, the earnings measure institutional buyers use. Commission is usually a flat 10-12% of the sale price, however complex the deal turns out to be.
The broker model usually leaves out three things: a targeted search for the buyers most likely to pay the most for your business, hard negotiation on deal structure beyond price, and running a confidential process in stages.
The Advisor Model: Build and Compete
An M&A advisor works the other way. We don't list the business and wait. We build a list of buyers likely to put a high value on this particular business (strategic acquirers, private equity firms and qualified individuals), then run a structured, confidential process that makes them compete. Our post on finding the right buyer covers how we build that list.
We negotiate well beyond the headline price: working capital targets, earnout structure, representations and warranties, transition terms. Our post on LOI gotcha clauses covers the kind of detail a listing-based process tends to miss.
In short:
A broker lists the business, waits for interest and charges a flat commission. That works well for simpler main-street deals.
An M&A advisor builds a targeted buyer list, runs a competitive and confidential process, and negotiates structure as hard as price. It's meant for larger, more complex transactions.
Confidentiality: Public Listing vs. Controlled Process
Broker listings often go up on marketplaces anyone can browse, your competitors, employees and customers included. An advisor-run process starts with a blind teaser that carries no identifying detail. Buyers are vetted before they see anything sensitive, and they sign an NDA before your name or financials go anywhere. See exactly how that works in a Blackland engagement.
The top bid off a public listing may come from a different buyer than the one a confidential process would find, and price is only one of a dozen terms in the deal.
Where the Line Actually Blurs
No regulation separates a "broker" from an "M&A advisor," and plenty of firms use the titles loosely. Ask about the process instead of the title. Do they find and approach specific buyers, or wait for inquiries? Do they negotiate structure, or just the number at the top of the page? Do they run a confidential process, or a public listing? Put those three questions to anyone you're considering, whatever they call themselves.
Size is a decent rule of thumb, if an imperfect one. Below roughly $10MM in revenue, a broker's simplicity and speed are often a fair trade for a business that doesn't need an elaborate competitive process. Above that, and especially in the $10-$100MM lower middle market, the business is more complex and the likely buyers more sophisticated, and a targeted, advisor-run process usually earns its extra work.
Business Broker vs. Investment Banker: Where Banks Fit
Investment banks sit at the other end. They run the same kind of targeted, competitive process an M&A advisor does, but most take sell-side mandates only on larger deals, often well above $100MM in deal value. In the $10-$100MM revenue range, the firms doing that work usually call themselves M&A advisors or boutique investment banks, and the label is most of the difference. The same three questions apply: who finds the buyers, who negotiates structure, and how confidential the process is. Blackland runs the investment banking process for lower middle market sellers.
Cost: Not as Different as You'd Expect
A flat 10-12% broker commission can look cheaper on paper than an advisor's fee, but that rarely holds once you factor in deal size and outcome. Advisor fees usually step down as transaction value goes up. A process where buyers actually compete often produces a meaningfully higher price, so a fee that looks higher as a percentage can still leave you with more dollars. Our post on how Blackland Advisors' fees work breaks down the full structure.
Whoever you talk to, ask them to walk you through the process they would run for your business, step by step.
