Bookkeeping onboarding checklist for 2024 (with template)

Here’s everything you should include in your client onboarding process, and exactly how to lay the groundwork for a fruitful relationship that lasts decades.

Two accounting professionals review a bookkeeping onboarding checklist together in a well-lit office, with a laptop and documents on the table to ensure a thorough client onboarding process.

There’s no second chance at a first impression. And the client onboarding experience at your firm is no exception.

It sets the tone for your entire relationship with them. And it’s critical to get right. 

In fact, client retention is the area most impacted by client onboarding. And when it costs 5-25 times more to acquire a new client than retain an existing one, the value of a solid and consistent client onboarding experience is clear.

Here’s everything you should include in your client onboarding process, and exactly how to lay the groundwork for a fruitful relationship that lasts decades.

Client onboarding checklist template for bookkeeping firms

The information in this guide is based on the Client Onboarding template from the Karbon Template Library.

This client onboarding template checklist will help to ensure that every step of your client onboarding is covered consistently and efficiently.

What to include in a bookkeeping onboarding checklist

An effective client onboarding experience will include certain key elements.

Here’s what you need to collect and store at the beginning of any new client relationship:

  1. Signed contract

  2. Welcome packet

  3. Basic client information and documentation

  4. Access to previous or existing accounting systems

  5. Accounts and invoice history

  6. Tax history

  7. Communication channels

1. Signed contract

The contract is the foundation of your relationship with your clients. It outlines the terms, expectations, and responsibilities of both parties. A well-drafted contract—and your client’s access to it—ensures legal clarity, outlines expectations, and sets the stage for a fully transparent partnership.

2. Welcome packet

A welcome package officially welcomes your clients to your services and team. It can include a personalized welcome email, letter, or video, an overview of your firm, mission, and pricing explanation.

3. Basic information and documentation collection

A client onboarding questionnaire is a great way to capture all the information you need to get started. Consider using an online form builder like Typeform so you can easily capture information like:

  • Business name, address, and phone number

  • Bank account access information

  • Credit card information

  • Tax ID numbers

  • Payroll information

  • Preferred point of contact and method of communication

4. Access to previous or existing accounting systems

Use your client onboarding questionnaire to capture login details for their previous or existing accounting software, like their GL, and any other relevant tech vendor.

5. Accounts and invoice history

A comprehensive invoice history provides insights into the client's payment habits, outstanding balances, and any historical billing issues. It sets up all of the effective billing and payment procedures going forward.

6. Tax history

Reviewing the client's tax history enables you to assess their compliance and identify any past tax liabilities or credits. It's essential for planning and ensuring the client's financial health.

7. Communication channels

Identify the primary contact person on both sides, preferred methods of communication (email, phone, meetings, etc.), and response time expectations.

Automating the client engagement stage of the onboarding process

In Karbon, the Client Onboarding template will give you a complete layout of all the documentation bookkeepers should gather, archive, and share with the client. You can customize this list as necessary.

This template within Karbon uses automation that handles much of the initial information collection and administrative work.

For example, automatic Client Request emails can be set up to request onboarding information from new clients. You can also set up automatic reminders to prompt them to complete their tasks.

Automators will also assign the job to the relevant team member based on its current stage.

Important steps during the client onboarding process

Here are five key steps to an effective and efficient client onboarding process:

1. Kick-off engagement

With your first client meeting scheduled, it’s important to provide them with the agenda. You want your client to come prepared and aware of what you aim to accomplish.

Reminder: Your kick-off meeting is just around the corner

Body text

  • [Agenda items]

[Onboarding Specialist name]

2. Conduct the meeting

Now it’s time to conduct the formal kick-off meeting via video conference or an in-person meeting. 

This is where you will:

  • Check-in on the onboarding process and current progress

  • Reiterate the scope of work

  • Confirm that you have access to all systems and tools

  • Cover any training materials or documentation

  • Clarify rules of engagement and preferred methods of communication 

  • Schedule a series of future meetings and deliverables

You can document thorough notes about any next steps or specific requests directly within the work item in Karbon to streamline future interactions.

Effective client onboarding meetings conclude with a follow-up email that details a full client summary and any important action items.

3. Gather important documents and chase for any missing information

There still might be important information that is missing or you may need access to, like access to accounting software, access to bank accounts, and account reconciliation history.

Depending on the size and history of the account, this may be a lot of paper shuffling for the client (as well as yourself). Once this information has been received, some firms send small ‘thank you’ notes and gifts as tokens of appreciation.

4. Prep the systems

Your client onboarding system is only as good as the tools you use to drive it.

If you haven’t already, create a client profile in your accounting practice management software and CRM—even better if your practice management and CRM are the same tool.

Prepare your billing schedule and process. Again, you’ll make the most of your billing if your practice management tool can invoice and collect payments—like Karbon can.

You’ll also need to invite your clients to other parts of your tech stack, including software like:

5. Establish a working relationship

Maximize your customer’s lifetime value by setting up a regular communication cadence.

Bookkeepers should define:

  1. Communication cadence. Determine the frequency and method of communication that works best for both parties. This may include regular check-in meetings, email updates, or utilizing project management tools to keep everyone on the same page.

  2. Billing processes. Transparency in billing is essential. Clearly outline your billing processes and payment expectations from the outset. Discuss billing methods, payment schedules, and any retainer or upfront fees, ensuring that both you and your client are aligned on financial matters.

  3. Cleanup of current records. Continuously assess the state of their financial data so the client feels assured they are receiving accurate and efficient ongoing accounting services.
