Business Valuation Engagement Letter Template: 14 Clauses You Need (2026)

A proper business valuation engagement letter template anchors the entire valuation process by defining who is being valued, why, on what date, against which standard of value, and at what fee. The American Institute of Certified Public Accountants (AICPA) Statement on Standards for Valuation Services (SSVS) No. 1 makes a written engagement understanding effectively mandatory for any CPA performing a valuation, and the National Association of Certified Valuators and Analysts (NACVA) Professional Standards (2025 edition) require the same for credentialed members. This guide walks the 14 clauses every engagement letter should contain, with a copy-ready scaffold and the technical compliance notes most templates skip.

What This Actually Means

An engagement letter is not a marketing document. It is the contract that legally binds the valuation analyst and the client to a defined scope of work, a defined output, and a defined liability envelope. When a valuation is later challenged in court, in a divorce proceeding, by the IRS, or by a disappointed buyer, the engagement letter is the first document subpoenaed. If the scope was vague, the standard of value was unstated, or the intended user was undefined, the entire valuation report can be excluded or discounted.

AICPA SSVS No. 1, issued in 2007 and still the operative standard for CPAs in 2026, requires the analyst to establish a written or oral understanding with the client covering nine specific items before performing valuation work. NACVA Professional Standards (Section IV, 2025 update) require a written engagement letter for every Conclusion of Value or Calculation of Value report. American Society of Appraisers (ASA) Business Valuation Standards BVS-I echoes the requirement. In practice, the AICPA’s nine-item floor has expanded to 14 standard clauses that protect the analyst, the client, and any third party who later relies on the report.

This is not legal advice and the scaffold below is not a substitute for review by counsel licensed in the relevant jurisdiction. Engagement letters are state-law contracts, and indemnification language, limitation-of-liability caps, and confidentiality carve-outs all need to be tuned to the analyst’s professional liability policy and the client’s specific facts. Use this as a starting checklist, not a finished document.

The 14 Clauses Every Business Valuation Engagement Letter Needs

1. Parties

Name the engaging party (almost always the client) and the analyst or analyst’s firm with full legal names and addresses. If the client is an entity, name the entity and the signing officer. If the valuation is being commissioned by counsel for litigation purposes, the engaging party should be the law firm, not the underlying client, to preserve work-product protection where available. This single drafting choice can determine whether the report is later discoverable.

2. Scope of Engagement

State precisely what is being valued: equity vs total invested capital, 100 percent of the equity vs a specific minority block, the operating company vs a holding company, and which subsidiaries or business lines are included or excluded. AICPA SSVS No. 1 paragraph 16 calls this the “subject interest.” Ambiguity here is the most common source of valuation disputes. If only the operating subsidiary is being valued, the letter must say so and exclude the real estate holdco, the deferred tax assets, and any non-operating investments by name.

3. Standard of Value

Specify one: Fair Market Value, Fair Value (statutory, jurisdiction-specific), Investment Value, Intrinsic Value, or Liquidation Value. Fair Market Value is defined by IRS Revenue Ruling 59-60 as the price at which property would change hands between a willing buyer and willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of the relevant facts. Fair Value under Delaware General Corporation Law Section 262 (the dissenters’ rights standard) is a different concept and produces a different number. The letter must cite which standard and, where statutory, which jurisdiction’s definition controls.

4. Premise of Value

State whether the valuation assumes a going concern, an orderly liquidation, or a forced liquidation. Going-concern premise assumes the business continues operating in the ordinary course. Liquidation premises produce materially lower numbers, often 30 to 60 percent below going-concern value for asset-light service businesses (estimate, based on practitioner experience). Mixing premises within a single report without explicit disclosure is a SSVS No. 1 violation.

5. Intended Use

Name the specific purpose: gift tax filing, estate tax filing, divorce settlement, shareholder buyout, ESOP transaction, SBA 7(a) financing, purchase price allocation under ASC 805, impairment testing under ASC 350, litigation support, management planning, or sale of the business. AICPA SSVS No. 1 paragraph 16(d) requires this. A valuation prepared for a gift tax return at a discounted minority value cannot be repurposed by the same client to anchor a sale negotiation. The intended use locks the report to its purpose.

6. Intended Users

List the parties authorized to rely on the report by name or class: the client, the client’s tax counsel, the IRS, opposing counsel in litigation, the buyer’s lender, the ESOP trustee. Any party not named is a third party with no reliance rights, and the report should say so. This clause works in tandem with the limitation-of-liability clause to define the analyst’s exposure universe.

7. Valuation Date

State the as-of date in unambiguous form (December 31, 2025, not “year-end 2025”). The valuation date is the single most consequential variable in any valuation. For estate tax, it is the date of death or the alternate valuation date six months later under Internal Revenue Code Section 2032. For divorce, state law dictates: California uses date of separation, New York uses date of commencement, Texas uses date of trial. The letter should also note whether subsequent events known after the valuation date but reasonably knowable on the date will or will not be considered (the “known or knowable” standard from Revenue Ruling 59-60).

8. Report Type

This is where SSVS No. 1 gets technical. The standard recognizes three deliverable types and the letter must name one:

A Calculation of Value is explicitly not an opinion of value and cannot be marketed as one. NACVA Professional Standards 2025 and AICPA SSVS No. 1 both require that any Calculation Report carry a prominent disclosure that the analyst did not perform the procedures necessary to issue a Conclusion of Value. Misusing a Calculation Report in a tax filing or court proceeding has produced disciplinary actions from both bodies.

9. Fees and Payment Terms

State the fee structure: flat fee, hourly with cap, hourly without cap, or phased. State the retainer, the billing schedule, the late-payment terms, and what triggers an additional fee (scope expansion, additional valuation dates, rebuttal reports, deposition or trial testimony). The 2025 NACVA fee survey reports business valuation engagements typically run $5,000 to $50,000 depending on company size, complexity, and report type, with litigation engagements and ESOP valuations clustering at the high end and small Calculation of Value engagements at the low end. Contingent fees are prohibited under AICPA SSVS No. 1 paragraph 14 and NACVA Professional Standards Section III for any engagement producing an opinion of value, because the analyst’s independence would be compromised.

10. Indemnification

The client agrees to indemnify the analyst against third-party claims arising from the client’s misuse of the report, the client’s misrepresentations to the analyst, or the client’s failure to disclose material facts. This clause is heavily negotiated in litigation engagements and is sometimes carved back to exclude the analyst’s own gross negligence or willful misconduct. Most professional liability carriers require an indemnification clause as a condition of coverage.

11. Limitation of Liability

Cap the analyst’s aggregate liability at a defined dollar amount, often the fee paid or a multiple thereof (1x to 3x is common in non-litigation work). Exclude consequential, indirect, and punitive damages. Note that several states, including New York and California, will not enforce a liability cap below a “reasonable” amount in cases of gross negligence, and a few states will not enforce caps at all in professional services contracts. Counsel review is non-optional on this clause.

12. Confidentiality

Mutual confidentiality covering the client’s financial and operational information shared with the analyst, and the analyst’s work product and proprietary methodologies shared with the client. Carve-outs for disclosures compelled by subpoena, court order, regulator request, or peer review by AICPA, NACVA, or ASA. Define the survival period (typically 3 to 7 years post-engagement) and define what counts as Confidential Information vs information already in the public domain.

13. Deliverable Timeline

State the target completion date, the document request list delivery date, the management interview date, the draft report delivery date, and the final report delivery date. Make the timeline contingent on the client’s timely delivery of requested information. Most disputes about timing trace back to incomplete or late document production by the client, which the letter should explicitly address with a “client delay” clause that resets the analyst’s deadlines proportionally.

14. Signatures

Original ink signatures or compliant electronic signatures (DocuSign, Adobe Sign, and similar platforms that meet the federal ESIGN Act and the relevant state UETA adoption). Date each signature. If the client is an entity, the signer should warrant authority to bind the entity. If counsel is engaging the analyst on behalf of the underlying client, counsel signs and the underlying client may countersign in an acknowledgment block.

Worked Example: A Real Engagement Letter Scaffold

Below is a copy-ready text scaffold for a Conclusion of Value, Summary Report engagement for a hypothetical $8 million revenue HVAC company being valued for shareholder buyout purposes. Replace bracketed placeholders. This is not legal advice and should be reviewed by counsel before use.

BUSINESS VALUATION ENGAGEMENT LETTER

Date: [Date]

To: [Client Entity Legal Name], a [State] [entity type], with principal offices at [Address] (“Client”).

From: [Analyst Firm Legal Name], [State] [entity type], with principal offices at [Address] (“Analyst”).

1. Parties and Engagement. Client engages Analyst, and Analyst accepts the engagement, to perform a business valuation of the Subject Interest defined below in accordance with the terms of this letter.

2. Scope and Subject Interest. The Subject Interest is 100 percent of the issued and outstanding common equity of [Operating Company LLC], a [State] limited liability company that operates a residential and light-commercial HVAC service business. Excluded from the Subject Interest are the following: (a) [Real Estate Holdco LLC], which owns the operating premises; (b) any non-operating cash above $200,000 of working-capital cash; (c) the deferred compensation arrangement with [Owner Name] documented in Exhibit A.

3. Standard of Value. Fair Market Value as defined in IRS Revenue Ruling 59-60: the price at which the Subject Interest would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell, and both having reasonable knowledge of the relevant facts.

4. Premise of Value. Going concern. Analyst will assume continued ordinary-course operation of the business as of the Valuation Date.

5. Intended Use. Internal shareholder buyout pursuant to the Buy-Sell Agreement dated [Date] among the equity holders of Client. The Report shall not be used for any other purpose without Analyst’s prior written consent.

6. Intended Users. Client, the equity holders of Client identified in Exhibit B, and Client’s tax and legal counsel of record. No other party shall be entitled to rely on the Report.

7. Valuation Date. [Date], the most recent fiscal year-end of Client.

8. Report Type. Conclusion of Value, Summary Report, as those terms are defined in AICPA Statement on Standards for Valuation Services (SSVS) No. 1 and NACVA Professional Standards. Analyst will consider the income, market, and asset approaches and will document the methods relied upon and the methods considered and rejected.

9. Fees. Fixed fee of $[Amount], 50 percent due on execution of this letter and 50 percent due on delivery of the final Report. Additional services beyond the scope above (including additional valuation dates, rebuttal reports, deposition or trial testimony, or scope expansions requested by Client) will be billed at $[Rate] per hour. Late payments accrue interest at 1 percent per month. Analyst’s fee is not contingent on the conclusion reached, on any future transaction, or on any future event.

10. Indemnification. Client shall indemnify, defend, and hold harmless Analyst from and against any third-party claims, damages, and expenses (including reasonable attorneys’ fees) arising from (a) Client’s misrepresentation or omission of material facts to Analyst, (b) Client’s misuse of the Report, or (c) Client’s distribution of the Report to any party not identified as an Intended User. This indemnity does not extend to claims arising from Analyst’s gross negligence or willful misconduct.

11. Limitation of Liability. Analyst’s aggregate liability under this engagement, regardless of legal theory, shall not exceed two times (2x) the fees actually paid by Client to Analyst under this letter. In no event shall Analyst be liable for consequential, incidental, indirect, special, or punitive damages.

12. Confidentiality. Each party shall hold the other’s Confidential Information in confidence and shall not disclose it to any third party except (a) to its own professional advisors bound by confidentiality, (b) as required by subpoena, court order, or regulator request, or (c) as required by peer review under AICPA, NACVA, or ASA standards. This obligation survives termination for five (5) years.

13. Timeline. Analyst will deliver a document request list within five (5) business days of execution. Conditional on Client’s complete response within twenty (20) business days, Analyst will deliver a draft Report within forty-five (45) days of receipt of the complete document response, and a final Report within fifteen (15) days of Client’s comments on the draft. Delays in Client’s document production extend Analyst’s deadlines on a day-for-day basis.

14. Governing Law and Signatures. This letter is governed by the laws of the State of [State] without regard to conflict-of-laws principles. Signed by authorized representatives of Client and Analyst below.

____________________________   ____________________________

[Client Signer Name, Title]                     [Analyst Signer Name, Title]

Date: ______________                         Date: ______________

This scaffold is approximately 600 words once placeholders are filled. A litigation-grade Detailed Report engagement letter for an estate tax filing or ESOP transaction will typically run 8 to 12 pages once expert-witness clauses, document-retention obligations, and detailed scope-of-work exhibits are added.

Common Mistakes

Leaving the Standard of Value Blank

“Fair value” and “fair market value” sound similar and produce different numbers. Statutory fair value under most state dissenters’ rights regimes excludes the minority discount that fair market value typically applies, which can swing the conclusion by 15 to 35 percent (range based on Delaware Chancery Court opinion patterns). If the engagement letter is silent or ambiguous, the analyst can be forced to defend a conclusion against a definition that was never agreed to.

Failing to Exclude Non-Operating Assets

HVAC companies, dental practices, and other owner-operated businesses frequently hold the operating real estate in a separate entity, carry excess cash, or maintain a personal-use vehicle on the company books. If the engagement letter does not list what is excluded from the Subject Interest, the analyst either inflates the valuation by including non-operating assets or invites a dispute about what was supposed to be in or out. Exhibit-list the exclusions by name.

Allowing Contingent Fees

A fee structured as a percentage of the valuation conclusion, or contingent on a future transaction closing, voids the analyst’s independence under AICPA SSVS No. 1 paragraph 14 and NACVA Professional Standards Section III. The report cannot be used for any purpose requiring an independent opinion of value, including all tax filings, all litigation contexts, and most lender requirements. The fee section of the engagement letter must affirmatively state non-contingency.

Confusing Calculation of Value with Conclusion of Value

A Calculation of Value is faster and cheaper because the analyst performs only the procedures the client and analyst agree to perform. It is not an opinion of value and cannot be used where an opinion is required. Clients sometimes ask for a Calculation Report because of the price and then attempt to use it in a tax filing or a court proceeding. The engagement letter should name the report type unambiguously and the analyst should refuse client requests to repurpose a Calculation Report outside its agreed scope.

Omitting the Intended User List

Without a named-user clause, every party who reads the report has a colorable argument that they relied on it. A buyer’s lender, a divorcing spouse’s counsel, or a state taxing authority can claim reliance and sue if the conclusion turns out unfavorably. Naming the Intended Users and disclaiming all other reliance in both the engagement letter and the report itself is standard malpractice-defense hygiene.

Skipping Counsel Review of Indemnification and Liability Caps

State law varies on the enforceability of liability caps in professional services contracts. New York Public Officers Law and California Civil Code Section 1668 both impose limits. An engagement letter copied from an online template and not reviewed by counsel in the analyst’s state of practice can leave the analyst with an unenforceable cap and unlimited exposure. Every analyst should have a base template reviewed annually by counsel familiar with their state’s professional services case law.

Timeline and Process

From the first client conversation to a signed engagement letter, the typical timeline runs as follows:

Day 1 to 2: Intake call. Analyst gathers preliminary facts: what is being valued, why, by when, and for whom. Analyst confirms no conflicts of interest and confirms the engagement falls within the analyst’s competence (a CPA who has never valued a mineral interest should refer the engagement out).

Day 2 to 5: Analyst sends a preliminary fee estimate based on report type, complexity, and the intended-use deadline. Client confirms budget and timeline.

Day 5 to 10: Analyst drafts and sends the engagement letter using the firm’s master template, customized to the specific facts. Client routes to counsel for review.

Day 10 to 20: Counsel-to-counsel negotiation on indemnification, liability cap, governing law, and confidentiality. This is where most engagement letters spend the bulk of their pre-signature time.

Day 20 to 25: Signatures collected. Retainer invoice sent and paid. Engagement officially commences and the document request list goes out the same day.

Day 25 onward: Document production, management interviews, financial analysis, market research, valuation modeling, draft report, client comments, final report. For a Summary Report on a $5 to $20 million revenue business, expect 60 to 90 days from engagement-letter signature to final report. For a Detailed Report on a litigation matter, expect 90 to 180 days. For a Calculation of Value, expect 30 to 45 days.

Compliance Cross-Reference: AICPA, NACVA, and ASA Standards

The three standards bodies that govern most US business valuation work overlap heavily but not perfectly. An engagement letter that satisfies AICPA SSVS No. 1 will typically satisfy NACVA Professional Standards 2025 and ASA Business Valuation Standards, but the analyst should confirm clause-by-clause against the credentials actually held.

A handful of differences matter in practice. NACVA’s 2025 update strengthened the written-engagement requirement and added explicit disclosure language for Calculation Reports beyond what AICPA requires. ASA Business Valuation Standards add more detailed approach-and-methods documentation requirements that affect the scope-of-work exhibit rather than the engagement letter itself. The IRS, when reviewing valuations submitted with gift or estate tax returns, applies its own review criteria under Revenue Ruling 59-60 and the IRS Job Aid for Valuation of Non-Controlling Interests, which assume the underlying engagement letter complied with at least one of the three credential bodies’ standards.

Frequently Asked Questions

Is an oral engagement understanding enough under AICPA SSVS No. 1?

Technically yes for AICPA members. SSVS No. 1 paragraph 16 permits either a written or oral understanding. In practice, no insurer, no court, and no NACVA or ASA standard accepts oral engagements as adequate. Get it in writing every time. The cost of a one-page engagement letter is negligible against the cost of defending an undocumented scope dispute.

How much does a business valuation cost in 2026?

The 2025 NACVA fee survey reports a typical range of $5,000 to $50,000 depending on report type, company size, industry complexity, and intended use. Calculation of Value engagements for small businesses cluster at the low end ($5,000 to $12,000). Summary Reports for mid-sized companies typically run $15,000 to $30,000. Detailed Reports for ESOP transactions, gift tax filings, and litigation matters routinely exceed $40,000 and can reach six figures for complex multi-entity structures.

Can the same engagement letter cover both a valuation and a sell-side advisory engagement?

No. The two engagements have different scopes, different fee structures (sell-side is typically success-based, valuation must be non-contingent), and different deliverables. Combining them invites a conflict-of-interest challenge. Sell-side advisory work for a transaction should be documented in a separate engagement letter or M&A advisory agreement. For a deeper look at how sell-side advisors actually work, see our guide on how investment bankers value a business.

What is the difference between AICPA SSVS No. 1 and NACVA Professional Standards?

AICPA SSVS No. 1 binds CPAs performing valuation services as part of CPA-firm practice. NACVA Professional Standards bind NACVA credential holders (CVA, MAFF, ABAR) regardless of CPA status. ASA Business Valuation Standards bind ASA credential holders. Most credentialed analysts are subject to two or three of these simultaneously, and the engagement letter should comply with the strictest applicable standard. In practice, an engagement letter that satisfies AICPA SSVS No. 1 will also satisfy NACVA and ASA in most respects.

Does a business valuation engagement letter need to be renewed annually?

No. Each engagement letter covers a specific engagement with a specific valuation date and a specific deliverable. A new valuation date or a new intended use requires a new engagement letter, not a renewal. Many firms maintain a master services agreement with recurring clients and execute a short engagement letter (sometimes called a “task order”) for each specific valuation.

What happens if the client refuses to sign the indemnification clause?

Most analysts will not proceed without it. The client’s professional liability carrier may require it. The analyst’s carrier almost certainly does. If the client refuses, the analyst’s options are to walk away, to negotiate a heavily-capped indemnity that mirrors the limitation-of-liability cap, or to raise the fee to price in the unhedged exposure. Walking away is the most common outcome for litigation engagements and the least common for friendly internal-use engagements.

What to Do Next

The engagement letter is the first deliverable in any valuation engagement and the document most likely to determine the analyst’s exposure if the engagement goes sideways. Use the 14-clause checklist above as a starting point, customize the scaffold to the specific facts, and route the result through counsel before signature. Skipping any of the 14 clauses to save drafting time creates risk that compounds across the life of the engagement.

If the valuation is the first step toward selling the business, the engagement-letter exercise becomes the warm-up for a much larger document set: a confidential information memorandum, a non-disclosure agreement template, a letter of intent, a definitive purchase agreement. CT Acquisitions runs sell-side processes on a buyer-paid fee structure, meaning the seller does not pay an upfront retainer or hourly fees, and the advisor is paid by the buyer at close. That model removes the contingent-fee independence problem that prevents valuation analysts from doubling as transaction advisors and lets the seller get both an independent valuation and a sell-side process without paying twice.
