Client Onboarding Checklist
Engagement and paperwork
Lock the agreement down before any work or access starts.
- Send and get a signed engagement letter setting out scope, fees, and terms
- Confirm the fee, billing model, and payment terms in writing
- Set up how the client pays you and get the payment method on file
- Agree the start date and the first period you are responsible for
- Run a conflict-of-interest check against your existing clients
Access and credentials
Get into the systems you need for the client.
- Get accountant or user access to QuickBooks Online, ideally with your own login rather than a shared password
- Connect or get read access to all business bank and credit-card accounts and their feeds
- Set up a shared, secure folder for documents and receipts
- Exchange logins through a password manager rather than email or text
- Get access to any invoicing, bill-pay, or expense tools the client uses
Records and opening balances
- Collect the most recent financial statements (profit and loss, balance sheet)
- Get the latest filed tax return and any correspondence from the tax authority
- Confirm the opening balances and the date they are as of
- Get the current chart of accounts, or confirm you will build one
- List the bank loans, credit lines, and other liabilities with current balances
- Get the contact details for the client's accountant or tax preparer, and agree how you hand off at year-end
- Get the open accounts-receivable and accounts-payable list with aging
System setup
- Review and clean up the chart of accounts in QuickBooks Online
- Connect the bank and credit-card feeds and confirm they pull cleanly
- Enter or import the opening balances and reconcile them to the latest statements
- Set up bank rules and recurring transactions for the common entries
Process and cadence
- Send a welcome note and book a kickoff call to walk the client through what happens next
- Agree the month-end close timeline and what the client must send, by when
- Set the main point of contact and the response time each side can expect
- Pick the communication channel and where questions get logged
- Agree the management-report package and the day of the month it lands
- Confirm who approves bills for payment and the payment runs
Compliance and handover
- Confirm how you store and handle the client's data, and who can access it
- Set a backup and document-retention routine for the client's records
- Document the engagement in your practice management or client list
- Schedule a check-in at the end of the first full month to confirm the process works
This onboarding checklist is a customizable template, not legal or compliance advice. Requirements vary by jurisdiction and by the specifics of your practice and client. Adapt it to your own process and confirm any regulated steps with a qualified professional.
What is a bookkeeping client onboarding checklist?
A client onboarding checklist is the ordered list of steps you work through when taking on a new bookkeeping client, from the signed engagement letter to the first clean month-end close. It turns the handful of things that have to happen, getting access, gathering records, setting up the books, agreeing the cadence, into a repeatable process rather than a scramble you reinvent for each client.
The checklist earns its keep in the gaps it closes. The steps that cause trouble later are the easy ones to skip in the rush of a new client: a bank feed left unconnected, opening balances never reconciled, a reporting cadence never agreed. Writing them down means none of it rides on memory under time pressure.
What to include in a client onboarding checklist
A workable checklist moves through the same stages, whatever the client. The generator above builds each of these from your inputs:
- Engagement and paperwork. The signed engagement letter, the agreed fee and terms, a conflict check, and identity verification where the rules require it. Nothing else starts until this is locked down.
- Access and credentials. Accountant access to the accounting software, the bank and credit-card feeds, and any payroll or tax portals, exchanged through a password manager rather than email.
- Records and opening balances. Prior financial statements, the last filed tax return, the chart of accounts, outstanding receivables and payables, and the opening balances with the date they are as of.
- System setup. Cleaning up the chart of accounts, connecting the feeds, reconciling the opening balances, and configuring sales tax or payroll where they apply.
- Process and cadence. The month-end close timeline, the reporting package and when it lands, the point of contact, and the response time each side can expect.
- Compliance and handover. How the client's data is stored and handled, a backup and retention routine, and a check-in at the end of the first full month to confirm the process works.
Why access and paperwork come before the work
An onboarding stalls when the bookkeeping starts before the foundations are in place. Without a signed letter there is no agreed scope. Reconciling is impossible until the access is clean. And if the opening balances are never confirmed, every report built on top of them inherits the guess. All three are cheap to fix at the start and expensive to unwind a month in.
That is why the generator orders the checklist the way it does. The engagement and access steps come first, the records and setup steps depend on them, and the cadence and compliance steps close out a client who is fully live. Tailoring the list to the services and software keeps it specific to this engagement rather than a generic catch-all.
Frequently asked questions
What should a bookkeeping client onboarding checklist include?
At a minimum: the signed engagement letter and agreed fees, access to the accounting software and bank feeds, the client's prior records and opening balances, the system setup and reconciliation, the reporting cadence and point of contact, and how you handle and back up their data. Services like payroll or sales tax add their own steps, which is why a tailored checklist beats a generic one.
What is the difference between an engagement letter and an onboarding checklist?
The engagement letter is the agreement: it defines scope, fees, and terms, and it gets signed. The onboarding checklist is the operational to-do list that follows once it is signed, the steps you work through to get the client fully set up and live. The signed letter is usually the first item on the checklist.
Can I edit the checklist after I download it?
Yes. The download is an editable Word document, not a locked PDF, so you can add your firm's own steps, remove anything that does not apply, and reuse it as your standard onboarding template for every new client.
How long should onboarding a new bookkeeping client take?
It depends almost entirely on how fast the client responds. The setup, access, records, and system configuration can be done in a week or two when access and documents come through promptly, and drag on for weeks when they do not, which is why the checklist front-loads those requests. A client whose books are behind also needs catch-up work, which is scoped and quoted separately from the ongoing engagement.
