M&A Advisor for $1M-$100M Business Owners
What an M&A advisor does, how they differ from a broker, what they charge, and how to choose one.
An M&A advisor manages the sale of your business end to end: the valuation, the preparation, the search for buyers, the competitive process, and the negotiation through to close. For an owner in the $1M-$100M range, the right advisor is the difference between a bilateral deal at the first buyer's number and a competitive process that tests the whole market.
Key takeaways
- An M&A advisor runs the full sell-side process: valuation, preparation, buyer sourcing, a competitive process, negotiation, and close.
- An M&A advisor is not a business broker: brokers list smaller businesses to individual buyers; an advisor runs a targeted, confidential competitive process.
- Fees are a retainer plus a success fee, typically a single-digit percentage of the sale price. At FISART the retainer is credited against the success fee.
- Senior involvement is the thing to check: who runs your deal day to day matters more than a slightly lower fee.
- A good advisor pays for itself by running enough buyer competition to more than cover the fee.

What an M&A advisor does
An M&A advisor takes a business owner through the entire sale, from setting a defensible value to signing the final agreement, and runs it as a managed process rather than a single negotiation. The role is strategic and operational at once: part valuation, part project management, part negotiation, all aimed at the highest achievable price with the fewest failed deals.
The work breaks into stages. First, valuation and preparation: normalizing earnings, building the data room, and fixing the issues a buyer would use to chip the price. Then buyer sourcing: identifying and approaching a wide universe of qualified buyers under NDA, not just the advisor's existing contacts. Then the competitive process: moving interested buyers to indicative offers and letters of intent in parallel, so leverage stays with the seller. Finally, execution: managing confirmatory diligence and legal drafting through to close.
The reason this matters is that most owners sell once and have no learning curve. An advisor who runs dozens of deals a year brings the process discipline, the buyer access, and the negotiation experience that a one-time seller cannot. For how the sale itself unfolds, see how to sell a business and the FISART process.
M&A advisor vs business broker
An M&A advisor and a business broker do related work at different ends of the market, and choosing the wrong one costs value. A business broker typically lists smaller, owner-operator businesses on a marketplace and matches them with individual buyers. An M&A advisor runs a targeted, confidential competitive process for larger businesses, approaching strategic, private equity, family-office, and search-fund buyers directly.
Business brokers handle the large majority of deal volume but a small share of total deal value, because they concentrate on Main Street businesses. For a business earning meaningful EBITDA in the $1M-$100M range, the advisor model usually produces a materially higher outcome, which more than covers the higher fee.
| Dimension | Business broker | M&A advisor |
|---|---|---|
| Typical business size | Main Street, often under $2M value | Lower middle market, $1M-$100M revenue |
| Buyers approached | Individual buyers via a marketplace listing | Strategic, PE, family office, search funds, targeted |
| Process | Listing and matching | Structured competitive process |
| Confidentiality | Public or semi-public listing | Anonymized, NDA-gated |
| Fee model | Flat commission | Retainer plus success fee |
There is a genuine overlap in the $5M-$15M range where both models compete. For most healthy businesses of that size, a targeted competition among vetted buyers lifts the price enough to justify the advisor's process. The detailed comparison lives on M&A advisor vs traditional broker.

What an M&A advisor charges
M&A advisors charge a retainer plus a success fee, and the structure is designed to align the advisor's incentives with a strong closed price. The retainer funds the upfront preparation and process work; the success fee, paid at close, is typically a single-digit percentage of the sale price, often on a scaled basis where the rate steps down as the price rises.
Fees are not the number to optimize in isolation. A slightly lower success fee is a poor trade if the advisor cannot generate offers as high as a stronger firm. What matters is the net result after fees, and a good advisor pays for itself by running enough buyer competition to more than cover the cost. At FISART, the retainer is credited against the success fee, so you are not paying twice for the same work.
Two details are worth checking with any advisor. First, whether the retainer credits against the success fee, because if it does not, you pay for the preparation and then pay the full success fee again at close. Second, what the success fee is calculated on when the deal includes earn-outs, seller notes, or rolled equity, and when it becomes due. FISART sets these terms transparently in a confidential consultation. For how fees fit the broader engagement, see exit planning.
How to choose an M&A advisor
Choose an M&A advisor on senior involvement, relevant track record, process quality, and buyer access, not on the lowest headline fee. The single most useful question is who will actually run your deal day to day, because at many firms the senior who wins the mandate hands the work to a junior team once the engagement is signed.
Look for four things. Senior involvement: a named senior advisor on your deal from first call to close. Track record: real completed transactions in your size range and, ideally, your sector. Process: a clear, structured competitive process with a defined buyer strategy, not a listing. Buyer access: a genuine, wide, and well-matched buyer universe, because competition is what drives price. A firm that runs many deals a year has seen more structures and knows more buyers than one doing two or three.
Fit matters too. Selling your business is a months-long, high-stakes engagement, and you want an advisor who is candid about your readiness and your realistic value rather than one who wins the mandate with an inflated number and renegotiates later. That candor is part of the FISART approach.
How FISART works as your M&A advisor
FISART is an M&A advisor for owners of $1M-$100M businesses, built around a personal senior advisor, a three-month preparation program, and a structured competitive sale. The model targets the two things that cost owners the most: going to market unprepared, and going to market to too few buyers.
You work with a personal senior advisor from the first call to the closing table, not a rotating junior team. The engagement begins with a three-month exit preparation program that fixes the issues buyers use to chip the price, strengthens the value drivers, and builds the data room. Preparation then flows directly into a structured competition across the FISART network of more than 250 vetted strategic acquirers, private equity firms, family offices, and search funds. This is where AI-powered buyer sourcing earns its place: data pipelines and buyer-matching widen the pool beyond any one advisor's personal network, which is what drives price through real competition. AI adds reach and precision. It does not replace the advisor, and it does not run your negotiation.
Two further points define the model. FISART is US-headquartered with strong US buyer reach, so international and cross-border owners can access American buyers a domestic-only advisor would never approach, as covered on selling to US buyers. And fees are a retainer plus a success fee, with the retainer credited, so incentives point at a strong closed price.
