Business Broker vs. M&A Advisor

Business Broker vs. M&A Advisor: What's the Actual Difference?

A business broker helps you sell a small business, typically under $2M. An M&A advisor runs a structured sale process for larger companies, usually $10M and up. Between those two ranges, things get confusing fast.

We see this confusion constantly in conversations on Rejigg. An owner with a $4M business calls three intermediaries and gets three wildly different pitches: one wants to list it on BizBuySell for a 10% commission, another wants a $25,000 retainer to run a "full M&A process," and the third says something vaguely in between. The owner has no idea who to trust or what they actually need.

This article breaks down what each type of intermediary does, how they charge, and where the gray zone gets messy. Then we'll talk about whether you need either one at all.

What Does a Business Broker Actually Do?

A business broker is essentially a real estate agent for businesses. They list your company on marketplace sites, field calls from interested buyers, help with some basic due diligence, and try to close the deal. Most brokers handle businesses valued under $2M, though some work up to $5M.

Here's what that looks like in practice. The broker creates a listing (usually a one-page summary called a CIM, or Confidential Information Memorandum), markets it across listing sites, screens incoming buyer leads, facilitates tours or calls, and helps negotiate the purchase agreement. They handle the paperwork and try to get you to closing.

Brokers typically don't run a competitive bidding process. They find a buyer, you negotiate with that buyer, and hopefully you close. If that buyer falls through, they find another one. It's a sequential process, one buyer at a time.

Most states require business brokers to hold a real estate license, though the rules vary. In some states, anyone can call themselves a broker with no license at all. That's worth checking before you sign anything.

What Does an M&A Advisor Do?

An M&A advisor runs what the industry calls a "process." That means they actively pursue and solicit multiple potential buyers simultaneously, create competition among them, and manage a structured timeline designed to maximize your sale price.

A typical M&A process looks like this: the advisor spends 4-6 weeks building a detailed CIM and financial model. Then they identify 50-200 potential buyers (both strategic acquirers and private equity firms), reach out to all of them under NDA, collect initial indications of interest, narrow the field, run management presentations, solicit final bids, and negotiate terms with the top 2-3 bidders.

This is fundamentally different from what a broker does. The advisor creates a competitive dynamic where multiple buyers are bidding against each other. That competition is what justifies the advisor's fees. When it works, it can push your sale price significantly higher than what a single-buyer negotiation would produce.

M&A advisors are typically registered with FINRA (Financial Industry Regulatory Authority) as broker-dealers, or they operate under an exemption. They hold Series 79 and Series 63 licenses. This regulatory framework means they have fiduciary obligations that business brokers often don't.

How the Fees Compare

The difference in fee structures is significant and worth understanding before you talk to anyone.

Business brokers charge a commission on the sale price, usually 8-12% for deals under $1M and 6-10% for deals in the $1-5M range. No retainer, no upfront fees in most cases. If the business doesn't sell, you don't pay. This sounds appealing, but it also means the broker's incentive is to close any deal, not necessarily the best deal.

M&A advisors charge a monthly retainer (typically $5,000-$15,000/month for 6-12 months) plus a success fee that's a percentage of the transaction value. The success fee is usually 3-5% and often follows a tiered structure called a Lehman or Modified Lehman formula, where the percentage decreases as the deal size increases. On a $10M deal, total advisory fees might be $300,000-$500,000. On a $3M deal, those same fees would eat up a painful chunk of your proceeds.

For a $5M business, the math looks like this. A broker at 8% costs $400,000. An M&A advisor with a $10,000/month retainer over 8 months plus a 4% success fee costs $280,000. The advisor is cheaper on paper, but you're paying that retainer whether the deal closes or not.

The $2M-$10M Gray Zone

This is where most of the confusion lives. Your business is too big for a traditional broker to handle well, but too small for most M&A advisors to care about.

Brokers who work in this range often lack the financial sophistication to present your business properly to experienced buyers. They might not know how to normalize your financials, build a quality of earnings analysis, or explain your working capital needs. Buyers at this level expect a more polished process, and a poorly prepared CIM can actually hurt your sale price.

M&A advisors, on the other hand, often have minimum deal sizes of $10M or higher. The ones who will take a $3M engagement might be junior teams at larger firms or solo practitioners who left a bigger shop. The quality varies wildly. And their fee structure, built for $20M+ deals, can feel disproportionate at lower valuations.

Here's what usually happens. An owner with a $4M EBITDA business (probably worth $12-20M depending on the industry) gets good attention from M&A advisors. But an owner with $600K in EBITDA (worth maybe $2-4M) gets passed over by the advisory firms and pushed toward brokers who may not be equipped for the deal's complexity.

If your business falls in this gray zone, ask yourself two questions. First, how complicated is the deal?

A straightforward asset sale of a single-location service business is different from selling a multi-location company with earnout potential, real estate components, and key employee retention issues. Second, how much do you need someone to find buyers for you? If you already know who might buy your business (a competitor, a private equity group that's been sniffing around), the value of an intermediary drops considerably.

How M&A Advisors Run a "Process" Differently

The structured process is the main thing you're paying an M&A advisor for, so it's worth understanding what that actually means.

A broker lists your business and waits for buyers to come to them. An advisor goes out and finds buyers proactively. They'll build a target list of 50-200 potential acquirers, research which ones have acquisition history in your space, and reach out to all of them systematically. This outbound approach generates more interest and creates the competitive dynamic that drives higher valuations.

The advisor also controls the timeline. Everyone gets the same information at the same time.

Bids are due on the same date. This prevents one buyer from dragging out diligence while another loses interest. It also gives you leverage: when a buyer knows there are other bidders, they sharpen their pencil.

The process typically takes 6-9 months from engagement to close. That's longer than a broker-facilitated sale (which can close in 3-6 months), but the theory is that the structured approach yields a higher price that more than offsets the extra time.

For businesses in the $2-10M range, though, this full process can be overkill. You might not need 150 potential buyers. You might need five good ones. And you might not need six months of process when a direct conversation with the right buyer could get there in three.

Do You Actually Need Either One?

This is the question most owners skip, but it's the most important one. Brokers and advisors both have a financial incentive to convince you that you need them. Of course they're going to say yes.

The honest answer: you probably don't. The main things a broker or advisor provides are buyer access, deal structure knowledge, and negotiation support. All three are available without paying someone 5-10% of your company's value.

Buyer access used to be the hardest part. Twenty years ago, finding qualified buyers for a small business meant networking, cold-calling, or hoping someone saw your ad in the local business journal. That's genuinely changed. Online marketplaces have made buyer discovery dramatically more efficient.

Deal structure knowledge matters, but it's learnable. The basics of asset vs. stock sales, earnout structures, seller financing, and SBA loan mechanics are all well-documented. And for the complex stuff, you can hire a transaction attorney for a flat fee or hourly rate that's a fraction of an intermediary's commission.

Negotiation support is where people get nervous about going solo. But here's the thing: nobody knows your business better than you. A broker who spent two weeks learning about your company will never explain its value as well as you can. Our article on selling without a broker walks through how owners handle this themselves.

The Third Option: Sell Direct on a Marketplace

Rejigg was built specifically for the owner who doesn't want to hand over 8% to a broker or $150,000 to an advisory firm. The platform gives you the tools to run your own sale process at your own pace.

Your listing goes in front of pre-vetted buyers who have signed NDAs before they see any sensitive details. You communicate directly through built-in messaging and video calls, with no middleman playing telephone. Your financials live in a secure data room where you control access. And you can compare offers side-by-side on a deal dashboard that shows enterprise value, earnout terms, and financing structures in one view.

The valuation calculator gives you a free estimate of what your business is worth using real transaction multiples, so you go into conversations knowing your number. And the entire platform is free for sellers. Buyers pay, not you.

This works especially well in that $2-10M gray zone where brokers are underqualified and M&A advisors are overpriced. You get the marketplace reach and deal infrastructure without the commission.

How to Decide

If you've read this far and still aren't sure which path makes sense, here's a simple framework.

Consider a business broker if: your business is under $1M in value, you have zero interest in being involved in the sale process, and you're okay with a single-buyer negotiation that might leave money on the table.

Consider an M&A advisor if: your business is worth $15M or more, you want a competitive bidding process among strategic and financial buyers, and the advisory fees represent a small enough percentage of the deal that the potential price uplift justifies the cost.

Sell direct on Rejigg if: your business is in the $1M-$30M+ range, you want to control the process and the timeline, you'd rather keep the 5-10% commission in your pocket, and you're willing to be involved in buyer conversations (which, honestly, most serious buyers prefer anyway).

The right answer depends on your deal's complexity, your tolerance for being hands-on, and simple math. A 10% broker fee on a $3M sale is $300,000. That's real money. For most owners, that's money better spent on a good M&A attorney, a quality of earnings report, and a platform that connects you directly with buyers.

Frequently Asked Questions

What is the difference between a business broker and an M&A advisor?

A business broker lists businesses for sale (usually under $2M) and works on commission, typically 8-12%. An M&A advisor runs a structured bidding process for larger deals ($10M+), charges a monthly retainer plus a 3-5% success fee, and actively solicits multiple buyers to create competition. Brokers are more passive, advisors are more hands-on.

At what business size should I use an M&A advisor instead of a broker?

Most M&A advisors focus on businesses worth $10M or more, where their fees (retainers plus success fees) represent a reasonable percentage of the deal. Below $5M, a full advisory process is often overkill, and the fees eat too much of your proceeds. The $5-10M range is a judgment call based on deal complexity.

Can I sell my business without a broker or M&A advisor?

Yes. Platforms like Rejigg give sellers the tools to list their business, connect with vetted buyers, manage due diligence through a secure data room, and compare offers directly. Seller listings are free. Many owners in the $1M-$30M+ range sell successfully without an intermediary, keeping the 5-10% commission for themselves.

How much do M&A advisors charge for small business sales?

M&A advisors typically charge a monthly retainer of $5,000-$15,000 for 6-12 months, plus a success fee of 3-5% of the transaction value. For a $5M deal, total fees might run $200,000-$350,000. Many advisors won't take engagements below $5-10M because the economics don't work for their business model.

Do business brokers need to be licensed?

Requirements vary by state. Most states require business brokers to hold a real estate license, but some have no licensing requirement at all. M&A advisors typically register with FINRA and hold Series 79 and Series 63 licenses. Always verify credentials before signing an engagement letter with any intermediary.
