Full Template Text
Copy the usable agreement below, replace every [BRACKET] placeholder, then customize for your situation.
This is a starting template, not legal advice. Have a qualified attorney review it for your jurisdiction and use case before signing.
An engagement letter template helps professionals start every client relationship on clear terms. Whether you are an accountant, consultant, lawyer, architect or agency owner, a signed engagement letter confirms what you will do, what you need from the client, how you charge and how the engagement can end, before any work begins.
Disclaimer: This template is informational reference material, not legal advice. Professional rules differ by country and profession, so adapt it to your jurisdiction and consult a lawyer or your professional body.
What Is an Engagement Letter?
An engagement letter is a short agreement, written as a letter from the professional to the client, that defines the engagement. It covers the services included and excluded, the responsibilities of both sides, fees and billing, any retainer, timeline, confidentiality, limitation of liability and termination. The client accepts by signing. For ongoing project work you can pair it with a consulting agreement, and for monthly advisory work a retainer agreement may fit better.
Key Clauses in This Engagement Letter
- Scope of Services — Exactly what is included and who leads the work.
- Services Not Included — What is out of scope and how extra work is quoted.
- Responsibilities of Each Party — Your professional duties and the client’s obligation to provide accurate information.
- Fees, Billing and Retainer — Hourly, fixed or value-based fees, invoicing frequency and deposits.
- Timeline — Start date and expected completion.
- Confidentiality and Data Protection — Including legal disclosure duties.
- Limitation of Liability — A cap, where your law and professional rules allow it.
- Termination — Notice period and payment for work done.
- Acceptance by Signature — The client confirms it has read and accepts the terms.
How to Customize This Template
- Describe the services precisely — “Preparation of 2026 corporate tax return” is better than “tax services.”
- List exclusions — Audits, litigation support or extra meetings often cause fee disputes.
- Match your professional rules — Some professions must include specific disclosures, complaint procedures or insurance details.
- Explain how the retainer is handled — Say when it is applied to invoices and how refunds work.
- Review the liability cap — Make sure it is permitted and clearly visible to the client.
