Business Broker or Investment Banker: Which One Do You Need?

The quick answer

If your business is likely to sell for under about $2 million, a business broker is almost always the right fit. If it will clear $5 million or more, most sellers in that range work with an investment banker or M&A advisor. In between, the title on the card tells you far less than the buyers an advisor can reach and the process they run.

Key takeaways

• The standard reporting line puts Main Street at zero to $2 million in enterprise value and the lower middle market at $2 million to $50 million. It is a convention, not a rule.
• What really changes with size is the buyer pool. Deals under $500,000 draw an average of 1.86 offers, while deals from $5 million to $50 million draw 4.71.
• Private equity is essentially absent below $5 million and a meaningful buyer group above it, which changes who sits across the table.
• Fee structures differ in shape, not just size. Ask for the full schedule in writing before you sign anything.
• Licensing varies by state, and selling stock instead of assets can trigger securities rules.

A broker and a banker do different jobs, not two versions of one job

A business broker sells an operating company, usually one the owner also runs day to day. The work leans on preparation: recasting financials to show what the business truly earns an owner, writing a confidential profile, listing where individual buyers look, screening inquiries, and walking one buyer through financing and diligence to a close.

An investment banker treats the sale as a capital markets exercise, building a detailed information memorandum, assembling a targeted list of strategic and financial buyers, contacting them directly, and running a deadline driven process meant to put several parties at the table at once. The goal is not to find a buyer. It is to create competition among buyers already hunting for something like your company.

Bankers also handle partial sales and recapitalizations, while brokers almost always sell the whole company to one buyer. Those methods only pay for themselves at certain sizes, which is why the industry draws a line at all.

The dividing line sits at $2 million, and it is a convention, not a rule

The one widely used standard separates Main Street, meaning zero to $2 million in enterprise value, from the lower middle market at $2 million to $50 million. That is how transaction data gets reported, and it is useful because deals on either side behave differently.

It is not a legal boundary, though, and nothing requires you to change advisor types when you cross it. Plenty of brokers close deals well above $2 million, and plenty of boutique banks take engagements below $5 million when the company is interesting.

That overlap zone, roughly $2 million to $5 million, is where sellers hear the most conflicting advice, because both kinds of firms can credibly claim the work. Treat $2 million as a signal about the process your business deserves, not an instruction.

The clearer question is what happens to your buyer pool as your value rises.

The buyer pool changes more than anything else as deals get bigger

Start with competition. Deals under $500,000 draw an average of 1.86 offers. From $500,000 to $1 million it is 2.62, from $1 million to $2 million 2.81, from $2 million to $5 million 3.15, and from $5 million to $50 million 4.71. Fewer than two offers versus nearly five is the difference between negotiating and being negotiated with.

The kind of buyer shifts as well. Under $500,000, about 43 percent of buyers are first time buyers, 28 percent strategic acquirers, and 24 percent serial entrepreneurs, and they need education, patience, and often lender financing. From $5 million to $50 million, private equity becomes a meaningful group, buying platforms and add ons for companies they already own.

Geography follows the same curve. Between half and two thirds of buyers for smaller businesses are within 20 miles of the seller, because they plan to show up and run the place. On larger deals, about two thirds are more than 100 miles away.

Those shifts are why the process has to change too.

The two processes feel different from the inside

A broker’s process is sequential. You go to market, inquiries arrive over weeks or months, you meet buyers one at a time, and eventually one makes an offer. Engagement to close runs about six months under $500,000 and around nine above $1 million, with two to four of those months falling after a letter of intent is signed.

A banker’s process is staged. Preparation takes longer because the materials must survive professional scrutiny, then outreach goes out to many parties at once, indications of interest come back on a deadline, a short list gets management meetings, and final bids arrive on a second one. Most investment banking deals take nine months or more.

One number deserves attention before you assume the bigger process is safer. Among investment banking engagements, a median of about 32 percent never reach a closed transaction.

How long each process runs also shapes how each advisor expects to be paid for it.

How advisors get paid follows two different traditions

Brokers typically work on a success fee paid at closing, sometimes with a modest upfront fee for valuation and preparation. Bankers typically charge a monthly retainer during the engagement, credited against the success fee at some firms and not others. The retainer exists because preparation is substantial and because roughly a third of engagements never close.

The formula the industry still references is the Lehman formula from the early 1970s: 5 percent of the first million dollars of value, 4 percent of the second, 3 percent of the third, 2 percent of the fourth, and 1 percent of everything above four million. As deal sizes grew, a doubled version appeared at 10, 8, 6 and 4 percent, then 2 percent above four million.

Treat both as reference points the industry knows by name, not published standards. Fees vary widely by firm, size, and complexity, and no industry body publishes verified average fee data, so anyone quoting an industry standard percentage is quoting custom, not fact.

Ask instead for the fee schedule in writing: the success fee calculation, any retainer and whether it is credited, a minimum if one exists, expenses, engagement length, and the tail period during which a fee is still owed after the engagement ends.

Fees are negotiable. Licensing is not.

Licensing and regulation are messier than most sellers expect

There is no national license for selling a business. Roughly 17 states require a real estate license to broker a business sale, and every state requires one when real property is part of the deal, which matters if you own your building.

Securities law adds a layer. Selling a company by transferring its stock is legally a securities transaction, which historically required the intermediary to be a registered broker dealer, while an asset sale did not.

A federal exemption for M&A brokers took effect in March 2023 and eased much of this. It covers privately held companies with less than $25 million of EBITDA or less than $250 million of gross revenue in the prior fiscal year, the buyer must be acquiring control, meaning at least 25 percent of voting rights, and the buyer must intend to actively manage the business. The caveat is that it is federal only and does not remove state level registration requirements.

You do not need to master this. Just ask how an advisor is licensed in your state and how they handle stock sales, then look at what the choice means in dollars.

Here is what the numbers look like for one illustrative seller

Suppose you own a light manufacturing business. The figures below are illustrative only, meant to show how the math works.

Your seller’s discretionary earnings, meaning profit plus your compensation and personal expenses run through the company, come to $650,000. A buyer who will not run the business day to day must hire someone to do your job, and a market salary for that role is $180,000. So EBITDA, the measure larger buyers use, is $650,000 minus $180,000, or $470,000.

Now apply the median multiples on each side of the line. Priced in the $1 million to $2 million band at 3.0 times seller’s discretionary earnings, you are at $1,950,000. Priced in the $2 million to $5 million band at 4.0 times EBITDA, you are at $1,880,000. The gap is $70,000, about 3.6 percent of the higher figure. Your business sits on the line, and the line barely moves the price.

What moves is everything around the price: about 2.81 offers and mostly local buyers on one side, 3.15 offers and a tighter process on the other.

Fees show a wider spread. On a $1,950,000 sale, the original Lehman formula gives 5 percent of the first $1,000,000, which is $50,000, plus 4 percent of the remaining $950,000, which is $38,000, for $88,000 total, or about 4.5 percent. The doubled version gives $100,000 plus $76,000, or $176,000, roughly 9 percent. That is an $88,000 difference on the same deal, which is why you ask for the schedule in writing.

With the numbers in view, the choice gets easier.

Choose by the buyers an advisor can reach, not the title on the card

Here is the honest version. A strong broker running a real process for a $3 million company will beat a mediocre banker, and a specialist banker will beat a generalist broker on a $4 million deal because they already know the three acquirers who should be bidding. The label is a weak proxy for either.

So interview for what the label is supposed to stand for. Ask how many businesses like yours the advisor closed in the last two years, and ask for engagements taken versus deals closed, not just wins. Ask who they plan to contact, how many, and whether those buyers are individuals, strategics, or private equity.

Ask whether they will run a deadline driven process with multiple bidders or simply market the business and field inquiries. Ask who at the firm actually does the work, and how they handle a deal that stalls in diligence, because that is when you learn what you bought.

Finally, ask what valuation range they would put on your business today, what drives the low end versus the high end, and what they would fix if you were willing to wait 6 to 12 months.

Frequently asked questions

Can a business broker sell a company worth $10 million?

Some can and some cannot, which is why the question belongs to the firm, not the category. At $10 million your buyers include private equity and strategic acquirers mostly more than 100 miles away, and reaching them takes a targeted outreach list and institutional grade materials. If a broker can show closed deals in that range, the title is irrelevant. If their closings are all local owner operators under $2 million, you are buying the wrong network.

Do I still need an advisor if a buyer already approached me?

Usually yes, and arguably more than in a normal sale. An unsolicited buyer has done the math and benefits from being the only party in the room. With one bidder you have no leverage on price, terms, or structure, and the jump from one interested party to three shows up in outcomes. An advisor can run a quiet, limited process that keeps that buyer engaged while confirming whether anyone would pay more.

Is an investment banker more expensive than a business broker?

The total dollars are usually higher, though it is more complicated than one percentage. Bankers typically charge retainers that brokers do not, and success fee rates tend to decline as deal size rises, so a larger deal can mean a bigger check at a smaller rate. Compare the full package: retainer, whether it is credited, the fee schedule, any minimum, expenses, engagement length, and tail period.

What is the difference between an M&A advisor and an investment banker?

In everyday use, very little, and the terms are often interchangeable. Investment banker traditionally implies a registered broker dealer that can handle securities transactions, including stock sales and capital raises. M&A advisor is a broader, less regulated term common in the lower middle market, and it has spread since the federal exemption took effect in March 2023. Since neither title is standardized, ask the concrete question: how are you licensed, and how are you registered?

How long will the whole process take?

Plan on six to twelve months, with size driving most of the range. Deals under $500,000 average about six months from engagement to close, deals above $1 million run closer to nine, and investment banking processes commonly take nine months or longer. Two to four of those months come after a letter of intent, which is the diligence and financing stretch. Clean financials and documented processes shorten it.
