People often fail to see the value in engagement letters. Engagement letters, however, are a valuable part of a business relationship. In this article created by our team at Trafft, we’ll explain why letters of engagement are important. Then, you can read on to find some bookkeeping engagement letter samples to help you write your own.

First off, what is an engagement letter, and why should we all be writing them?

An engagement letter is a way of stating the expectations and terms of a business relationship.

It determines between you and the client the terms of your contract, including what the client needs to do, what you need to do, and the payment schedule. Attorney engagement letters, for example, are extremely common.

The best bookkeeping engagement letters contain:

  • A scope definition of the work.
  • What the client must do or provide.
  • Payment terms.

Benefits of having a bookkeeping engagement letter:

  • Both parties know exactly what is expected of them.
  • The client knows what to expect from you, the employer.
  • Prevention of ‘project creep’ – when terms are not defined, the client can ask for more and more money and/or benefits.
  • Protection for both of you, as the expectations were written down beforehand. This can prevent complaints.

Engagement letters are beneficial not just for the client, but for you as well.

Intelligent business people use them to avoid complaints and make sure everyone is on the same page.

This minimizes risk for your company, as these types of letters are legally binding. This means the client must go through with the payment if you perform the work expected.

Sections to Incorporate into Your Bookkeeping Engagement Letter

Here is the ultimate step-by-step guide to writing an amazing engagement letter. We will also provide some engagement letter samples so you can see what the finished product should look like.

Identification of parties

It is necessary to state who you are working for.

This may be a company, group, individual, or any other entity.

You need to specify this. Below is an engagement letter template you can use for identifying the parties.

Engagement Letter Sample:

Company Name

This is an agreement to provide [service type] services to [CLIENT].

This letter of engagement is between CLIENT (“your”, “you”, “CLIENT”) and COMPANY NAME (“we”, “The Firm”, “us”, “our”). This is in effect fromDATE (the “Agreement”). The purpose is the clarification of the expectations and responsibilities of each party.

The engagement of [COMPANY] will be dictated by the details of this Letter and the Engagement Terms defined in it.

Service or project scope

In the engagement letter, you’ll need to describe the services you will offer. These may include budgeting, accounts receivable, accounts payable, and/or advisory services. It also would include any other services you perform.

This is a vital component of the engagement letter. Without this detail, you cannot prove, after the fact, whether or not you provided the services you promised. By including exactly what you’ll do you reduce the risk of project creep. You can refer back to this letter if the client asks you to do something that is not on it. Then, you have the right to say no, or ask for more money for the extra service.

Period of engagement

It’s necessary to define how long the work or project will take. Is it for a set period or ongoing? This could mean monthly, yearly, quarterly – you need to define the terms of ‘ongoing’ if this is the case. You also need to write what happens if a client owes you payment.

Here’s an engagement letter sample statement for this:

In the case of this Agreement being terminated, the following financial obligation is in effect.  CLIENT has the obligation to COMPANY of payments already made, as well as prorated payments accrued and not yet paid.

Engagement Letter Sample 1:

Dear (CLIENT),

The purpose of this letter is to confirm the terms of our engagement. We would like to specify the terms and clarify the services we are going to provide to you.

These are the services we will perform for you each (quarter, year, month, write a specific time frame). (Add any services that you will provide to the client in this timeframe). These services will commence (date).

Engagement Letter Sample 2:

Each month, by the 25thbusiness day, we will have completed your monthly bookkeeping. This timeframe may be extended if we do not receive the necessary documents from you in a timely fashion.

Fees and charges

Here, you need to define exactly what your hourly rate is if that’s the fee structure you use. If you do not charge by the hour, you must charge per project, or charge a retainer or flat rate. Ask yourself, Do you charge in 15-minute intervals? Do you require payment within 7 days, 10, or 30? What about the extra expenses incurred?

You need to detail all of the above that is applicable to you. Then the client will know exactly how much to expect bills to be, and how often to expect them. We suggest you include a statement about what happens if the client requests something outside the terms of engagement.

You could include a part about what will happen if they make a late payment, such as a cancellation of services or a late fee.

Engagement Letter Template:

Below are the details of the fees we charge for our services. 

Please note these fees might be reviewed upon notice of change of scope, or change in volume of work.

[Service 3]      [price one time, hourly, annually, monthly, etc]

[Service 4]      [price one time, hourly, annually, monthly, etc]

Responsibilities of clients

Under most engagement terms, the client is required to perform specific actions.

These may include giving the required information or records to the business.

You need to be specific about exactly what the client is responsible for doing. Also, define exactly what information you need the client to provide.

Engagement Letter Template:

 Company  Responsibility

______________________(company name), as well as ________________,(Owner, or relevant person in company) are:

required to adopt accurate and effective accounting policies. We must maintain an efficient accounting system. We must authorize transactions and retain supporting documents for those transactions. We must safeguard assets. We must also create internal controls in order to ensure the accuracy and reliability of financial statements.

We must inform you about all suspected or confirmed fraud which affects the Company.

You must inform us if you know of any suspected fraud, or accusations of fraud. These may be received from employees, past employees, regulators, or anyone else.Additionally, you must ensure that the entity complies with the necessary laws and regulations.

Confirmation of agreement terms

The last section of your engagement letter should confirm the terms of the engagement.

This checks the client’s understanding of the contract. We’ve provided letter template examples below. The first is an example of this section of an attorney engagement letter.
