A business broker sells smaller, Main Street to lower-middle-market businesses through a marketed process. An M&A advisor runs a more targeted, curated process for lower-middle-market companies. An investment bank runs a formal auction for larger deals. All three are intermediaries who find a third-party buyer and charge a fee.
Verdict: Choose a business broker for smaller deals that need wide marketing, an M&A advisor for a curated lower-middle-market process, and an investment bank for larger businesses that justify a full auction. If confidentiality, speed, and paying no commission matter more than a marketed process, a direct sale to an operator-buyer can beat all three.

| Best for | Small owner-run businesses | Lower-middle-market owners | Larger, high-value businesses |
Which one fits your deal size
Match the intermediary to your size and goal. A business broker fits a smaller, owner-run business that needs a wide net to find any buyer. An M&A advisor fits a lower-middle-market company that wants a professional, curated process to a shortlist of real buyers without the cost of a full bank auction. An investment bank fits a larger business where competitive tension across many strategic and financial buyers will create enough extra value to justify the retainer and success fee. Using the wrong tier, a bank for a tiny deal or a broker for a large one, costs you money or coverage.
When a direct sale beats all three
All three are intermediaries who market your business and charge a fee to find a buyer. A direct sale to an operator-buyer like WETYR skips the marketed process entirely: no retainer, no commission, no auction, and no widening circle of people who know the business is for sale. For owners in the $1M to $50M revenue range who value confidentiality and certainty over a marketed auction, the direct path is often the better economics and the lower risk, because the buyer is known and committed from the start.
What it costs
Fees differ by tier: brokers take 8 to 12 percent of the sale, advisors and banks charge a retainer plus a success fee that is a smaller percentage on larger deals. A direct operator sale carries no intermediary fee at all. Always compare net proceeds and certainty of close, not just the process each one runs.

Questions people ask about this comparison
What is the difference between a business broker and an M&A advisor?
Mostly deal size and process. Brokers handle smaller, Main Street to lower-middle-market businesses with a broad marketed listing. M&A advisors run a more selective, curated process for larger lower-middle-market companies, usually for a retainer plus a success fee.
Do I need an investment bank to sell my business?
Only if your business is large enough (often $10M+ enterprise value) to benefit from a full marketed auction. Below that, a bank retainer and fee are hard to justify, and a broker, advisor, or direct sale is the better fit.
Which is cheapest: broker, advisor, or bank?
As a percentage, banks and advisors usually charge less than brokers on large deals, but they add retainers. On smaller deals, brokers are often the only economical intermediary. A direct sale to an operator-buyer avoids all intermediary fees.
Can I skip all three and sell directly?
Yes. Selling directly to an operator-buyer or a known strategic acquirer avoids intermediary fees and keeps the process confidential. You still want a transaction attorney and an accountant, but no broker, advisor, or bank is required.
