What do you already have in place?
A few quick questions, so you can skip the steps you have already done. Each one has a line explaining what it means. Not sure, or never heard of it? Choose “Not yet / not sure”: that is where most firms start, and the playbook walks you through it.

Step 1: Agree scope and fee in writing
Done when: A signed engagement letter is on file.
Your task send the engagement letter before any billable work, listing the deliverables, what is out of scope, the fee basis, payment terms, how scope changes are handled, and the entities and years it covers.

How to do it, and what to read
Send the engagement letter before anything billable happens. List the deliverables, what is out of scope, the fee basis, the payment terms and how a change of scope is handled. Name the entities and years it covers, so a second company or a catch-up year is clearly extra. Ask for the signature and the payment details in the same step. Say a new client wants a tax return and a new company set up: that is two services, two lines in the scope, and a note on which one needs identity checks before it starts.

Step 2: Identify the client and assess the risk
Done when: Identity is verified and the risk assessment is saved to the client file.
Your task work out whether the services you will provide require identity checks under anti-money laundering rules where you practise, run the check before the long discovery conversation, and save a risk rating with its reasons to the client file.

How to do it, and what to read
First work out whether the services you will provide trigger identity checks where you practise; in Australia that turns on AUSTRAC’s list of designated services. Run the identity check before the long discovery conversation, because the result can change what you ask or whether you act at all. Then record a risk rating and the reasons for it: what the business does, where its funds come from, and who owns and controls it. The rating decides how much evidence you collect and how often you review the file.

Step 3: Collect what you need, once
Done when: Everything on the checklist is in, or chased with a date.
Your task build one request listing everything you need from the new client, such as documents, logins, prior-year returns, tax office authorities and software access, and send it once with a due date and one place to upload.

How to do it, and what to read
Build one request from the checklist: documents, logins, prior-year returns, authorities with the tax office and access to the client’s software. Send it once, with a due date and a single place to upload, instead of a trickle of emails. Mark each item as in, chased or not needed. Anything still missing at the due date gets one reminder with a new date, then a phone call. If you use AI to sort what comes in, the onboarding article sets out which steps suit it and which stay with a person.

Step 4: Tell the client how you use AI
Done when: The client has the AI notice and, where needed, has agreed to it.
Your task list every tool that will touch this client's data, including AI features inside software you already use, and tell the client in plain words what those tools do, where the data is held and that a qualified person reviews all work.

How to do it, and what to read
List the tools that will touch this client’s data, including AI features inside software you already use. Tell the client in plain words what those tools do, where the data is held, and that a qualified person reviews every piece of work. Put the AI clause in the engagement letter, and send existing clients a short explainer before their next renewal. If you record meetings, say so at the start of the call and cover it in the letter. The consent article sets out what the US, Australia, the UK and Canada each require.

Step 5: Book the first review
Done when: The review is booked and the client knows it is coming.
Your task book a review about 90 days into the new client relationship, compare the hours the work took with the fee before you meet, and set up the next review as a job with a due date in your practice management system.

How to do it, and what to read
Book a review about 90 days in, while the relationship is new. Before it, compare the hours the work actually took against the fee, and list anything you did that was not in the scope. In the meeting, ask what the client expected that they have not had yet. Leave with one of three answers: the scope and fee fit, the scope needs changing, or the fee does. Put the next review in your practice management system as a job with a due date, so it does not depend on memory.

What should be in a client onboarding checklist?
Signed engagement terms, identity checks and a risk assessment, the documents and logins you need, authorities with the tax office, software access, and a first review booked. The checklist template covers each one.
Do I need to identify every new client?
That depends on the services you provide and the anti-money-laundering rules in your country. Read the KYC guide and check your regulator’s rules for the services you offer. This is general information, not legal advice.
When should onboarding be finished?
Before any billable work starts. Collecting documents can overlap the first job, but the signed terms and identity checks should not.
