  1. 01 Step 01

    Step 01

    Onboard the client with AML checks and a signed engagement letter

    Per-client customer due diligence and a signed engagement letter are legal prerequisites. No work starts until they are done.

    Do it yourself

    • Run customer due diligence under the Money Laundering Regulations: verify identity and beneficial ownership, and assess and record the risk, before you start. An electronic ID and AML tool makes this fast.
    • Get the engagement letter signed (Module 3) and the service schedules agreed.
    • Complete HMRC agent authorisation for the relevant tax (Module 4), and confirm it has come through.
    • Set the client up in your software, portal and Direct Debit, then request their records with a tailored list.

    Common mistake · Starting the work before the ID and AML checks are complete and the engagement is signed. That is a compliance breach and a liability gap.

    CHECKLIST

    New client onboarding checklist

    The sequence that has to be finished before a client counts as "started". Customer due diligence and agent authorisation are regulated: this is a signpost, not advice.

    Step 02

    Do the first piece of work to its deadline

    Delivering one real job correctly and on time is the proof that your whole setup works.

    Do it yourself

    • Pick the first deliverable (a VAT return, a bookkeeping period, year-end accounts, or a tax return) and note its statutory deadline.
    • Confirm the client’s records are complete before you start, and chase any gaps early.
    • Do the work in your chosen software, filing digitally where Making Tax Digital applies.
    • Run a review checklist before you submit, because errors here are what drive claims.

    Common mistake · Leaving the first job until close to the deadline, then finding records missing or an authorisation that has not come through in time.

    Step 03

    File it and confirm with HMRC and the client

    The work is not done until HMRC has accepted it and the client knows what happens next.

    Do it yourself

    • Submit via compatible software and capture the HMRC submission receipt or reference.
    • Save the filed documents to the client’s portal folder.
    • Send the client a plain-English confirmation: what was filed, what they owe or are due, and when.
    • Diarise the next deadline immediately, so the following period is already on your calendar.

    Common mistake · Filing but not saving the receipt, or not telling the client what to pay and when, which leads to missed payments and "did you file it?" queries.

    Step 04

    Bill the work and get paid (the launch milestone)

    Getting paid closes the loop and proves the practice is a real, functioning business. This is the finish line of the first 90 days.

    Do it yourself

    • Raise the invoice at your agreed fee. Ideally the recurring Direct Debit is already collecting, so there is no surprise bill.
    • Reconcile the payment in your own bookkeeping.
    • Ask for a review at this high point (Module 8), and request a referral (Module 9).
    • Do a fifteen-minute retro on what took longer than expected, and what to templatise for client number two.

    Common mistake · Delivering well, then being slow or vague on billing. New practitioners often deliver beautifully and under-collect, because payment terms were never set at onboarding.
