Bookkeeping Engagement Letter + Template

When you are hired as a bookkeeper by a new client, it is important to send an “engagement letter” to your client. This document serves as the guide for your relationship, as it outlines the expectations and responsibilities of both parties during the bookkeeping process. Included is a template letter to use as a guide when you offer your services to a new client.


What is an Engagement Letter and Why Do You Need One?

An engagement letter is a contract between you and your client. It lays out the bookkeeping services that will be provided, how much you will charge for your services, and the payment structure and due dates. This document protects both parties by setting clear expectations from the start of the relationship.


The Components of a Bookkeeping Engagement Letter

There are a few key components that should be included in your bookkeeping engagement letter.

Names of the Parties: You and your client should both sign and date the letter. Make sure to include your full legal company name and address, as well as your client’s name and address.

Term of the Agreement: The term of your Agreement indicates the length of your relationship. Typically, a term is agreed to be month-to-month or for a period of one to two years in length. You will also want to state whether bookkeeping services will be submitted to your client on a monthly, quarterly or yearly basis, or as requested by your client.

Services to Be Provided: Outline the scope of the bookkeeping services that will be performed. This might include monthly bookkeeping, preparing payroll, and providing financial statements, as well as preparing preliminary tax reports. 

Compensation: Be specific about the amount agreed upon for payment of your bookkeeping services. This can be defined as an hourly rate, a monthly payment or on other terms as agreed.

Payment Schedule: Define payment due dates and any allowable special circumstances that may require a change of date for a one-time payment. 

Signatures: To create a binding Agreement, both parties will need to sign the engagement letter.


How to Write Your Own Bookkeeping Engagement Letter

Now that you know what needs to be included in a bookkeeping engagement letter, you can write your own. Here is a step-by-step guide:

Gather the necessary information. You will need the client’s full legal name, address, and contact information. You will also need to have a predetermined set of services you will provide as a bookkeeper for your client, how much you will charge for your services and when the payments will be due. 

Write the letter. Start by clearly stating that this is a bookkeeping engagement letter. Include the names and addresses of both parties, as well as the date of the agreement. Then, outline the bookkeeping services to be provided, the payments to be made and the due dates for those payments. Include a section for signatures at the end of the letter.

Sign the letter. You will want to provide two original copies of the engagement letter. You and your client will each sign both copies of the engagement letter.

Keep a copy of the letter. After signing, each of you will keep one fully-executed copy of the letter.
