An M&A advisory firm helps a business owner plan and pursue a sale, or helps a buyer assess and pursue an acquisition. Depending on the engagement, its work can include analyzing value and alternatives, planning the process, finding or evaluating counterparties, coordinating information and due diligence, advising on deal structure, and supporting negotiations through closing. The exact scope is set for the transaction; hiring an advisor does not transfer the owner’s decisions or responsibilities.
What an M&A advisor does for a seller
A seller-side advisor can help the owner consider strategic and financial alternatives, assess value, and choose an approach to a potential sale. The advisor may prepare or coordinate sales materials, identify and contact prospective buyers, and help manage diligence, deal structuring, negotiation, and closing.

Some processes begin with a target list and outreach. One documented procedure hosted by the SEC describes sending a potential buyer an executive summary with basic information that may initially leave the seller anonymous. That is an example of one firm’s procedure, not a universal process or a guarantee of anonymity.
The owner remains involved: the advisor needs accurate historical and current business information, and the owner makes decisions about the company and the transaction. Depending on the deal, the seller may also work with legal counsel, accountants, commercial bankers, and other consultants.

What an M&A advisor does for a buyer
On the buy side, an advisor may help evaluate acquisition targets, analyze value and strategic alternatives, and advise on timing, pricing, and structure. The advisor may also support diligence, negotiations, and closing, including work on valuation or structuring issues and related business matters.
What the engagement does—and does not—promise
There is no single transaction template. The work depends on the parties’ needs, the transaction, and the services agreed in the engagement. An advisor may coordinate with the client’s lawyers, accountants, commercial bankers, or other consultants, but the engagement should make clear who is responsible for each task.
Rank #2
Do not assume that every advisor runs an auction, contacts a particular number of buyers, guarantees confidentiality or a sale, or increases the final price. Fees, timing, and outcomes are specific to the engagement; no general fee range, average duration, or quantified advisor-created increase in sale value is established by the cited sources. Ask for the proposed scope, fees, assumptions, and any conflicts in writing.

M&A advisory firm versus business broker
These labels overlap and do not establish a universal scope or deal-size boundary. SEC-hosted regulatory material describes business-broker activities ranging from introductions to financial analysis, marketing a business for sale, and helping a client’s other advisors negotiate transaction terms. Broadly, business brokers often work with small or mid-sized businesses, while investment banks and M&A advisory firms may take on larger or more complex assignments. There is no current universal revenue cutoff that reliably separates the categories.
Rank #3
Compare the actual services, relevant experience, and responsibilities in the proposed engagement rather than relying on the firm’s title. Not every M&A intermediary is an investment bank.
How to evaluate a prospective advisor
Before signing, compare firms on the parts of the assignment that matter to your transaction:
- Relevant experience: Ask whether the firm’s experience and process fit your company’s size, industry, and transaction objective.
- Scope and deliverables: Identify exactly what the advisor will do and what stays with you or other professionals.
- Representation and conflicts: Clarify whom the firm represents in the work and how it identifies and addresses conflicts.
- Compensation: Understand the fee arrangement and whether any compensation is tied to the deal’s outcome or size.
- Confidentiality and communication: Ask how the firm handles buyer outreach, diligence materials, confidentiality, and updates to you.
- Registration, where applicable: For U.S. transactions, check the status of both the individual professional and the firm when broker-dealer registration may be relevant.
U.S. broker-dealer registration: why activities matter
In the United States, the SEC says that a person or firm helping with a transaction such as a company sale may need broker-dealer registration, particularly when compensation is transaction-related. The analysis is fact-specific. Relevant activities can include soliciting, negotiating, or executing securities transactions; compensation tied to the transaction’s outcome or size; and handling securities or funds. The SEC defines a broker as “any person engaged in the business of buying or selling securities for the account of others.”
That definition does not mean every business sale automatically requires broker-dealer registration, nor does a firm’s M&A label settle the question. Registration requirements and exemptions depend on the facts and applicable law. For a particular firm or transaction, consult qualified legal counsel rather than treating this overview as a determination of status.
Best Value
The SEC advises checking both the professional and the firm through Investor.gov, FINRA BrokerCheck, or the relevant state regulator. The SEC’s small-business broker-dealer guidance and Guide to Broker-Dealer Registration explain the activity-based considerations. This U.S. discussion should not be assumed to describe the rules in other countries.
