How to Protect You and Your Clients with a Better Engagement Letter

Duration of the Engagement

Pinpoint start and end dates for the engagement. If the project has multiple stages or phases, include key milestones so both you and your client can track progress along the way.

Tying those milestones to billing schedules can also make payments more predictable and transparent, which goes a long way in growing client trust and satisfaction.

Fees and Billing

Lay out how your pricing is structured in your engagement letter, whether your fees are fixed, hourly, or tied to certain outcomes. Be upfront about pricing, when payments are due, and which methods you accept so clients know if they can use online payments, checks, payment plans, or other options.

If you offer early-payment discounts or enforce late fees, note those here. Providing maximum clarity now helps prevent uncomfortable money conversations (and disputes) later.

Responsibilities of Each Party

Define not just what your firm will deliver, but also what you need from the client to complete the work. That might include timely access to financial records, availability for meetings, or prompt payment.

Outlining responsibilities on both sides sets the tone for accountability and keeps the work moving smoothly. If you have helpful tools that your client can use to fulfill their responsibilities, like a secure client portal for document sharing or progress updates, indicate it here.

Confidentiality Clause

Trust is everything. Strengthen it by including a confidentiality clause in your engagement letter that details your firm’s commitment to protecting client information.

Note any situations where data disclosure may be required, like legal obligations or regulatory requests, and confirm that any subcontractors you partner with are held to the same standards.

Termination Clause

Sometimes things don’t go as planned. A termination clause explains how either party can end the engagement, whether it’s due to a breach, performance concerns, or other reasons. Specify the required notice period and whether it needs to be in writing so expectations are clear from the start.

Why Your Accounting Firm Needs a Strong Letter of Engagement

An engagement letter is one of the most important tools your firm can use. Here are 7 ways a strong engagement letter benefits your practice:

1. 1. 1. Clearly Defines the Scope of Work
         An engagement letter lays out exactly what services your firm will provide: no more, no less. This clarity keeps everyone on the same page and prevents misunderstandings down the road.
      2. Mitigates Legal Risks
         Providing immediate clarity on the terms of your agreement gives you a layer of protection if disputes or legal issues arise.
      3. Establishes Fees and Payment Terms
         No one likes surprises when it comes to billing. An engagement letter makes your fees, payment schedule, and terms clear from the start.
      4. Ensures Confidentiality
         Including a confidentiality clause shows clients you take their sensitive information seriously to help you start building trust from the very beginning.
      5. Determines Duration of Engagement
         By outlining your planned start date, end date, and any key milestones, you give clients a reliable timeline for your services and keep expectations realistic.
      6. Sets Grounds for Termination
         A termination clause gives you and your clients protection by explaining how either party can end the engagement in certain circumstances and how notice should be provided.
      7. Enhances Professionalism and Credibility
         Providing a well-drafted engagement letter shows clients your commitment to transparency and sets the tone for the kind of professional, long-term client relationships that are essential to grow your firm.

   Top 12 Tips for Customizing Engagement Letters

   Engagement letters work best when they’re tailored to the client and the project. Here are practical ways to customize yours for clarity, protection, and professionalism:

   1. 1. Understand Your Client's Needs
         Take time to learn what your client expects to ensure the engagement letter is in alignment and accurately reflects what you're delivering, when, and for what fee.
      2. Keep it Clear and Concise
         While it's important to be comprehensive, avoid jargon and overly complex language that could confuse your client. Both sides should easily understand the terms of the engagement.
      3. Specify the Scope
         List and define what services are included, what’s excluded, and which extras may come with additional fees. Be as detailed as possible to help head off future disputes and stop scope creep.
      4. Address Deadlines and Timelines
         Include start dates, milestones, and delivery expectations to keep everyone in sync with straightforward timelines that can be consulted and revisited throughout the engagement.
      5. Be Transparent about Fees
         Explain your billing method, rates, payment terms, and any penalties or discounts that may apply (and under what terms). Financial conversations are always easier upfront!
      6. Examine the Confidentiality Agreement
         Ensure that your engagement letter’s confidentiality clause is tailored to the kind of information you'll be handling. In some projects, you might deal with more sensitive data that requires stricter confidentiality terms.
      7. Customize Dispute Resolution Methods
         Consider the nature of the project and the relationship with your client. Define how disputes will be handled, whether that’s mediation, arbitration, or litigation. If necessary, get with your legal staff to go over these details.
      8. Detail Termination Provisions
         Clarify your required notice periods, reasons for termination, and any related costs. This step can help ensure clients feel protected and know which steps to take if they decide to part ways.
      9. Incorporate Feedback
         Address client concerns early to build trust and mutual respect. If your client has questions about the engagement letter, their input can prove insightful and your willingness to listen to them can foster a sense of mutual respect and cooperation.
      10. Periodically Update Your Engagement Letter
          Make it a point to review and update your engagement letter templates at least once a year to keep them current and accurately reflect your pricing structure.
      11. Have Legal Review It
          Have a legal professional review your letter to make sure it’s complete and compliant. This is especially needed if you're venturing into new services or dealing with a complex project.
      12. Obtain Legal Consent
          Finalize with signatures, digital or handwritten, to make the agreement legally binding. When you use tools designed for accountants, like MangoShare eSignatures, a client’s digital signature is validated with bank-level security and dynamic Knowledge-Based Authentication (KBA) to prove the signer’s identity and ensure it's legally binding.
