Which to Use —Business Broker or M&A Advisor?

Both are intermediaries who connect buyers and sellers. But they serve different types of clients. How they serve them is also different, more so than most business owners expect. Which one best serves your M&A needs?

Size Matters Most

As a rule of thumb, M&A advisors typically handle transactions valued from about $10 million to hundreds of millions. In contrast, business brokers typically work with smaller businesses—sometimes those with less than $500,000 in sales.

Many larger B2B companies have national, even international reach. Those businesses nearly always use M&A advisors. In contrast, brokers focus on B2C or consumer-facing companies serving local communities, such as restaurants, retail shops, and specialists in trades such as carpentry and HVAC repair.

The Complexity Divide

Beyond the larger company’s size and geographic market coverage, its products, services, and financial control systems are also usually more complex — another way advisors and brokers part ways. Advisors operate in industries that can require specialized knowledge. Examples: software, aerospace, telecom, healthcare, professional services, and heavily regulated industries. Advisors also manage more complex deal structures, such as:

• Third-party financed acquisitions
• Cashless mergers between two private companies
• Sellers converting to ESOPs
• Carve-outs of divisions from larger companies
• Recapitalizations or partial liquidity events

These transactions require financial modeling, legal structuring, and, in some cases, lender participation and new minority investors. Brokers, by contrast, usually focus on selling all of the client’s assets or stock to an individual buyer or local competitor.

Breadth of Services

Good M&A advisors running a sell-side process assist clients with:

• Vetting the business and then recommending steps to enhance value in advance of sale
• Preparing extensive marketing materials
• Growth or acquisition financing
• Fairness opinions and
• Financial modeling

In contrast, brokers mostly concentrate on selling a business as-is, with limited pre-sale preparation and narrower buyer outreach.

As an aside, an even more sophisticated member of the financial intermediary family—the investment bank—handles deals valued at up to billions of dollars, invests alongside clients in transactions (underwriting), and takes companies public. The term “investment” means they invest their own money in the deals they promote.

Last, Compensation

Compensation for advisors and brokers reflects the differing levels of workload and complexity as described above. M&A advisors typically charge:

• A retainer (flat, monthly, or milestone-based), plus;
• A success fee upon closing.

Retainers reimburse the advisor for pre-sale work like financial modeling, access to proprietary databases and market research, internal DD, CIM preparation (see The Perfect Information Memorandum), and managing an M&A team over a period of months. Retainers also signal to the advisor that the client is as committed to completing the process as the advisor is.

Business brokers typically work on a success-fee basis only. Since their processes are shorter and less data-intensive, they can support more simultaneous listings and therefore operate on a contingency or pay-at-close basis, as real estate agents do. Compared to advisors, their success fees are higher, reflecting the smaller deal sizes they represent.

So, Which One Should You Use?

In sum, brokers and advisors serve different types of businesses with distinct processes and deliver varying degrees of deal preparation, company analysis, and marketing. M&A advisors address the transaction needs of businesses valued at up to $100 million and above, serving national and international markets with more complex offerings. Brokers tailor their services to fit the needs of smaller businesses serving local markets.

It’s like —

• You’d consider a chiropractor to soothe your aching back.
• But you’d choose a doctor to perform your annual check-up.

Where you stand on the choice between a broker and an M&A advisor depends on the characteristics of your company.
