Learning check · before you start

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.

  1. Is a signed engagement letter on file before any billable work starts?

    An engagement letter sets out the deliverables, what is out of scope, the fee basis and payment terms, and the entities and years it covers, so a second company or a catch-up year is clearly extra.

  2. Do you verify identity and save a risk assessment for each new client who needs one?

    In Australia identity checks apply to AUSTRAC's designated services, such as setting up a company or trust. A risk assessment records what the business does, where its funds come from and who owns and controls it, with a rating and the reasons for it.

  3. Do you ask a new client for all the documents and access you need in one request, with a due date?

    One list covering documents, logins, prior-year returns, tax office authorities and access to their software, sent once with a single place to upload, instead of a trickle of emails. Each item is marked in, chased or not needed.

  4. Do new clients get told, in plain words, how your firm uses AI?

    That means telling them which tools will touch their data, including AI built into software you already use, where the data is held, and that a qualified person reviews every piece of work. It usually sits as a clause in the engagement letter.

  1. 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.

    Learning check

    What would you do? Pick one; every answer is explained.

    A new client wants you to prepare their personal tax return and set up a new company for them. How do you write this into the engagement letter?
    A new client has signed your engagement letter but has not yet given payment details, such as a card or direct debit authority. What is the better approach?
    Your draft engagement letter says you will prepare “the client's accounts”. The client owns two companies and a family trust. What do you change?
  1. 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.

    Learning check

    What would you do? Pick one; every answer is explained.

    Under anti-money laundering rules, your firm must verify a new client's identity before providing certain services. When in onboarding should you run that check?
    Australia's anti-money laundering laws now cover some services that accountants provide. You are not sure whether a new client's work needs identity checks. What do you do first?
    A colleague onboarded a new client and saved a money laundering risk rating of “low” with no notes. Is the client file complete?
  2. 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.

    What would you do? Pick one; every answer is explained.

    You are onboarding a new client and keep remembering more documents and logins you need from them. How do you ask for them?
    You sent a new client one list of what you need, with a due date. The date has passed and two items are still missing. What next?
    You want to use an AI tool to sort and file the documents a new client uploads. How do you decide what the AI does?
  3. 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.

    What would you do? Pick one; every answer is explained.

    Nobody in your firm uses a chatbot, but your practice management software has AI features switched on, such as automatic summaries. Do these go on the list of tools you tell a new client about?
    Your firm records client meetings and uses AI to write up the notes. How do you handle this with a new client?
    Your firm has started using AI tools on client work. An existing client's annual engagement renewal is still months away. When should they hear about it?
  4. 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 would you do? Pick one; every answer is explained.

    You have just taken on a new client. When should you hold your first review of how the work and fee are going?
    You have a 90-day review booked with a new client. What do you prepare beforehand?
    Preparing for a new client's 90-day review, you find you have regularly done work that was not in the engagement letter. What should you leave the meeting with?

Frequently asked questions

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.
