The First Week That Sets the Tone: A Client Onboarding Timeline
A practical week-by-week timeline for onboarding new clients into your accounting practice — from engagement letter to the first job that actually moves.
New clients form their opinion of your firm fast. Long before you lodge anything, they are watching how you handle the boring parts: the engagement letter, the ID checks, the request for last year's figures. Get that first week right and you set a tone of competence that carries the whole relationship. Get it wrong and you spend the next twelve months explaining delays.
Most firms don't have a bad onboarding process — they have no process. Each new client gets whatever the person who signed them remembers to do, in whatever order they remember to do it. This is a look at what a deliberate first week can look like, and where good accounting client management software quietly does the heavy lifting.
Why the first week matters more than the first year
The work you do for a client in month six is largely invisible to them. They don't see the reconciliation, the review notes, the deadline you diarised. What they see up front is whether you're organised. A client who has to chase you for a portal login, or who signs an engagement letter that never comes back countersigned, has already learned something about how you operate.
The first week is also where the compliance groundwork gets set — or skipped. AML/CTF verification, the engagement scope, the terms of payment. These are far easier to nail before you've started work than to retrofit once you're three jobs deep and the client is emailing you as if you've always acted for them.
Day 1–2: Confirm the engagement and verify identity
The moment a prospect says yes, two things need to happen — and they can happen together. Send the engagement letter for e-signing, and run your KYC/AML checks. Doing these as one step avoids the classic problem of asking a client for the same documents twice, once for the engagement and again for verification a week later.
A few things to get right here:
- Scope in writing. Spell out exactly which services you're providing — BAS, annual accounts, tax return, advisory — so there's no assumption that "you do everything".
- Payment terms up front. The terms you set now are the ones you can enforce later. Bury them and you'll be chasing invoices you never agreed on properly.
- A signature you can track. An engagement letter sitting unsigned in someone's inbox is not an engagement. E-signing with a visible status means you know within seconds whether it's done.
If you're running this through account practice management software, the signed letter, the verification record and the client's core details all land in one place rather than scattered across your email, a shared drive and someone's memory.
Day 2–3: Set up the client record properly, once
This is where firms create problems for themselves. A rushed setup — a misspelt entity name, an ABN typed from memory, a company where there should be a trust — is a mistake that follows the client for years and eventually surfaces as a duplicate in Xero.
Take the extra ten minutes now:
- Enter the legal name, ABN and ACN accurately and check them against the register, not the client's email signature.
- Map the entity structure — who's the individual, who's the company, who's the trustee — so future work attaches to the right record.
- Connect the Xero file if you're the adviser, so ledger data and practice data stay in sync from day one.
Good client accounting software should make this a single, deliberate act rather than a form you fill in over and over. When client management and client accounting data flow from the same source of truth, you avoid the situation where one client quietly becomes three across your systems.
Day 3–4: Give them a front door, not your inbox
The fastest way to make onboarding feel chaotic is to run it through email. Documents get lost in threads, requests get missed, and the client never knows what's outstanding.
A client portal changes this. Instead of ten separate emails, the client logs in to one place where they can see what you need, upload it securely, and check the status. Your PBC (prepared-by-client) list lives there as a checklist the client can actually work through, rather than a document they read once and forget. When something's uploaded, it reaches you — it doesn't sit unnoticed in a folder.
The Finye portal gives clients that single login from the start, so the very first thing they experience is an organised front door rather than a scramble through your sent folder.
Day 4–5: Turn the relationship into actual work
Onboarding isn't a form you complete and file. It ends when real work is moving. The signal that a client is properly onboarded is a job on a board with a next action assigned to a real person.
Create the recurring jobs that reflect the engagement — the quarterly BAS, the annual accounts, the tax return — using templates so you're not rebuilding the same job every time a client signs. Diarise the compliance deadlines that apply: BAS and IAS cycles, the tax lodgment dates, the ASIC review date that so often gets missed because nobody wrote it down.
Worth being clear here: Finye isn't a tax return software or a ledger. It doesn't lodge the return or post the journals. What it does is track the obligation, hold the deadline, and run the work around it — so the return gets prepared on time and lands in the right lodgment tool with nothing forgotten.
The same discipline works for staff
Everything above applies when you onboard a new team member, too. A new staffer joining a growing practice needs the same clarity a client does: what's expected, where things live, and what the next action is. When your clients and your staff run on one system, onboarding a person means giving them access to boards, jobs and deadlines that already make sense — not a week of shadowing while they learn where everything's hidden.
Make it repeatable
The point of a first-week timeline is that it stops depending on who signed the client. Write it down. Template the jobs. Send the engagement letter and the AML request together. Set up the record once, accurately. Hand the client a portal instead of your inbox. Then let the first real job be the thing that tells you onboarding is done.
Do that consistently and the first week stops being the part of the relationship you dread — and becomes the part clients quietly remember you for.
