The Engagement Letter: A Section-by-Section Founder's Guide
The engagement letter is the contract that governs every aspect of the relationship. Read it section by section before signing.
M&A engagement letters are 8 to 15 pages of dense legal prose, organized in roughly the same order across firms. Once you understand the standard structure, you can read any engagement letter in 20 minutes and know what to push back on.
This guide walks through every section of a typical engagement letter, in the order they usually appear. For each section, what it says, what is negotiable, and what to walk away from.
Section 1: Scope of services
The first section defines what the banker is being hired to do. Typical language: "to act as exclusive financial advisor in connection with a potential sale, merger, or recapitalization of the Company."
What to push on: the scope of "transaction." If you only want to pursue a full sale, narrow the scope. "Sale of the Company" is narrower than "sale, merger, recapitalization, or strategic alternative." A narrower scope means you owe the banker a fee only if the specific kind of transaction in scope closes.
Why this matters: if you sign a broad scope and then accept a minority investment from a strategic investor instead of pursuing a sale, you may owe the banker a full fee anyway. That is sometimes what bankers want; it is rarely what founders want.
Section 2: Exclusivity
The exclusivity clause says you cannot hire another advisor or run a process without this advisor during the term. Standard.
What to push on: carve-outs. You should preserve the right to talk to your existing investors, your board, and your lawyers without the engagement applying. You should also preserve the right to respond to unsolicited inquiries during the term (with notification to the banker).
Be careful of language that says all such conversations must "go through" the advisor. That gives the advisor effective veto power over your communications with people in your existing network.
Section 3: Term
The term is how long the engagement runs. Standard term is 9 to 12 months from signing.
What to push on: shorter term, mutual termination rights, and the ability to extend by mutual agreement rather than auto-renewal. Anti-pattern: a 24-month term with the banker's unilateral right to extend.
Walk-away trigger: any clause that says the term is 24 months or longer with no mutual termination right in the first six months. That is a slave contract.
Section 4: Compensation
This is the heart of the document and where most negotiation happens. Compensation usually has three components: retainer, success fee, and expenses.
Retainer: ideally 25K to 100K total, paid in installments, fully creditable against the success fee. Walk away from large non-creditable retainers.
Success fee: percentage of transaction value, often with a tiered or step-up structure. Push for clear treatment of non-cash consideration (stock at closing-date value, earnouts paid as earned, rollover at face value).
Expenses: capped pass-through of out-of-pocket costs, monthly reporting, written consent required to exceed the cap. No in-house service billing.

Section 5: Definition of transaction value
This section defines what counts as "transaction value" for purposes of calculating the success fee. It is the most important section of the document after the tail.
Components typically included: cash, stock, assumed debt, earnouts (with specific treatment), escrow holdbacks (with specific treatment), rollover equity, employment-related amounts to founders if outside the deal, repayment of intercompany loans.
What to push on: earnouts paid only as earned, escrow released only when paid out, exclusion of personal employment compensation to founders (this should be a separate negotiation with the buyer, not part of the banker's fee base).
Section 6: Tail period
The tail clause survives termination and says the banker still gets paid on deals closed within the tail period with parties they touched. We have a full guide to tail traps.
What to push on: duration (12 months), scope (parties on a written contact log that you received during the engagement, limited to those who actually received the management book under NDA), excluded parties (pre-existing relationships listed by name at signing), successor advisor haircut (50 percent reduction if a new advisor closes the deal).
Walk-away trigger: 24-month-plus tail with "any party contacted" scope and no excluded parties list. That clause has bankrupted founders.
Section 7: Information sharing and confidentiality
This section covers the banker's confidentiality obligations and your obligation to share information with the banker.
What to push on: the banker should have the same confidentiality obligations they would impose on any buyer. The information you share should remain your property. The work product the banker creates with your information (CIM, model, buyer list) should be jointly owned and you should retain a license to use it after the engagement.
Specific concern: some engagement letters say the firm's analyses and work product are the firm's property. If you fire the firm and want to give the next advisor the data room and the model, the original firm should not be able to prevent you.
Section 8: Indemnification
The banker will want broad indemnification from you. Standard, but the scope matters.
Reasonable scope: indemnification for claims arising from inaccurate information provided by the company, third-party claims by buyers related to the process, regulatory inquiries about the company.
Unreasonable scope: indemnification for the banker's own negligence or misconduct. Push back. The banker should bear the risk of their own errors.
Make sure indemnification is mutual where appropriate (the banker indemnifies you for their misconduct), and that there is a cap on your indemnification obligation (usually 1.5x to 3x the success fee).
Section 9: Representations and warranties
Standard reps and warranties: the company has authority to enter the engagement, the information shared is accurate to the founder's knowledge, there are no undisclosed material liabilities.
Push back on: reps about the company's value, future performance, or buyer interest. Those are forward-looking and not appropriate to a sell-side engagement.
Section 10: Conflicts of interest
This section addresses the banker's other client relationships. You want disclosure of any current or recent representation of likely buyers.
What to push on: explicit disclosure obligation throughout the engagement (not just at signing), the right to require the banker to walk off a specific buyer if a conflict arises, and a mechanism for resolving conflicts that does not require you to terminate the entire engagement.
Section 11: Termination
How the engagement can be ended. Standard: mutual termination on 30 days written notice after an initial period (often 6 months), with specified treatment of unpaid retainer, owed expenses, and the tail clause.
What to push on: clear termination triggers, no unilateral termination right for the banker only, and post-termination obligations limited to the tail (the banker should not have ongoing rights to information about the company after termination).
Our firing guide covers the practical mechanics of using this section.
Section 12: Disputes
How disputes between you and the banker get resolved. Almost always arbitration, often in the banker's home jurisdiction.
What to push on: arbitration in a neutral jurisdiction, allocation of arbitration costs (usually loser pays), and a carve-out for injunctive relief (you should be able to go to court for emergency relief if the banker is breaching the engagement in real time).
Section 13: Miscellaneous
The grab-bag section. Includes governing law, notice provisions, integration clause, severability, assignment restrictions.
Specific item worth checking: assignment. The engagement should not be assignable by the banker without your consent. If the firm gets acquired or the partner leaves, you may not want the engagement to follow them.
Before you sign
Three final tips. First, run the engagement letter past an M&A specialist lawyer, not just your corporate counsel. The fee and the experience are worth it. Second, mark up the document in track changes and send it back. Bankers expect this. Founders who do not push back are leaving money and protection on the table. Third, time the negotiation early in the relationship, before you have publicly committed to the firm. Once you are emotionally locked in, your negotiating leverage is gone.
And read founder-verified reviews of the firms you are considering before you sit down to negotiate. The bankers who consistently get high marks for fair dealing in their engagement letters are the ones most worth your time. When your own engagement is done, add a review so the next founder gets the same benefit.
