Engagement Letter – Uses, Contents, Format, Free Templates

The engagement letter is a legally binding agreement that establishes the terms of the business relationship between a company and its clients.

It helps the company communicate what the client should expect in terms of the service it will provide. It includes information such as the scope, costs, and responsibilities of both parties, among other details.

An engagement letter is often used by professional firms. These firms may provide accounting, legal representation, consulting, and auditing services, among others.

Establishing expectations helps to reduce the risk of conflict that may lead to litigation by either party. It also helps protect the company’s payment by setting up a fee structure for the client. Companies must clearly understand when and how often they should use an engagement letter, what should be included in it, and its benefits.

    When and How Often is the Engagement Letter Used?

    A company should create an engagement letter before starting its business relationship with a new client. Though the engagement letter is less formal than a contract, it is a legally binding agreement. It plays an important role in ensuring that the company communicates appropriately to its client without using the legal jargon associated with a contact. An engagement letter contains the company’s services to its clients, its terms and conditions, cost, deadlines, and other details.

    The information relayed in the engagement letter is effective for a long period. However, companies should review the document to make appropriate updates. This review can be done annually. Significant changes to pricing, terms, and conditions, the scope of service, or the services offered to the clients may warrant changes to the letter.

    A new engagement letter or supplement letter can be created to outline the updates the company would like to make. The reviews and updates made to the engagement letter help the company maintain its professional standards. A termination clause that allows both parties to exit the engagement under certain applicable conditions should be indicated. 

    What to Include in an Engagement Letter

    Companies must clearly understand what to include in their engagement letters. The components of the letter help ensure that information is appropriately conveyed to clients. It also helps ensure that key details are not left out of the agreement.

    The following information should be contained in an engagement letter:

    Parties identification

    The engagement letter should begin by identifying the parties involved. It will help identify who the service provider is and who the client is. The document should specify whether the client is an individual, group, or partial entity.

    For example:

     James Smith
    456 Main Street,
    Atlanta, Georgia 14560

    Service type

    Secondly, the type of service that is being provided to the client by the company should be identified. It helps clarify what the client should expect from the company. The statement identifying the type of service the company will provide should be short and straightforward.

    For example:

    Dear James,
    This is to confirm the legal services being provided by James and Jane LLP.

    Specific service details

    Thirdly the engagement letter should provide specific details about the services the client should expect to receive. A brief description of the services will help the company avoid misunderstandings with the client.

    For example:

    The services that will be provided under this letter are legal consultation services.

    Scope of service

    Next, the company should outline the scope of its services. It helps create an understanding of the work that needs to be done. It will also help reduce scope creep.

    For example:

     Our firm will consult on a business-related matter. Our services will include:

    Conducting legal analysis and researching legal matters
    Reviewing your legal documents
    Providing advice on legal matters

    Period of engagement

    The engagement letter should also outline when the engagement starts and ends. The company can go further by specifying the delivery date for specific deliverables if any. It will help highlight the due date and enable the client to follow up on the progress of the work.

    For example:

    The engagement will begin on March 6th,2021, and end on March 10th,2023.

    Fee structure

    A clear fee structure outlining the cost of the services provided to the clients should be indicated. The free structure should include information on how and when the payments will be expected. In addition, the company should establish how it will go about changing for extra services the client may request that have not been indicated in the engagement letter. A clause outlining what will happen in the event of late payment should also be included.

    For example:

    Our hourly rates are$ 62. This amount is based on the time spent consulting on issues that may be brought to us. An extra $170 for any additional services that are not indicated in this engagement letter.

    Responsibilities of each party

    A brief description of the responsibilities of each party throughout the engagement should be outlined. The client may be responsible for certain actions and providing specific information, among other responsibilities. It will help ensure that both parties are clear on what they need to do to ensure the engagement goes smoothly.

    For example:

    The client will be responsible for providing relevant information and documentation. Access to business documents should also be granted to aid in the provision of appropriate advice. The advice provided is simply an opinion, and the client is free to accept or decline it. On the other hand, we will provide informative, reliable advice to help the client. We  are also responsible for maintaining  our client’s confidentiality

    Professional standards

    The engagement letter should contain a statement assuring the client that professional standards will govern the engagement. The standard will depend on the location of the parties involved.

    For example:

    The engagement will be governed by the standards and requirements of The State Bar of Georgia.   This, therefore, means that we are bound by state law to ensure the confidentiality of our client’s information and the provision of reliable information.


    The company should also include a disclaimer to help establish the limitations of the service. It helps avoid confusion and complaints that may be brought about by a lack of understanding of the company’s services.

    For example:

    The firm will only provide the services listed for the period indicated. The client will need to seek legal representation elsewhere for any matters that must be brought before a court. The client shall also be informed of any updates or changes to the firm’s services that may occur within the set period.

    Validity and termination

    A brief statement should be indicated highlighting that the engagement letter is valid until the due date or till the complete delivery of the service. It helps reassure the client of the company’s commitment to the terms they have laid out. The engagement letter should also contain a termination clause. The clause provides information on why the engagement may be terminated. It also outlines how the relationship can be ended.

    For example:

    The agreement is valid for four years. At which point it can be terminated. It can also be terminated without notice by either party.

    Confirmation of term

    Lastly, the engagement letter should end with confirming the terms laid out within it. The statement is used to verify that the client fully understands the document. Both parties must review and sign the document against their names to show that the terms are agreeable to them.

    For example;

    We hereby accept the terms outlined in the engagement letter.
    Full name:
