Short answer: whatever your engagement letter says, which for most Sydney bookkeeper arrangements is 30 days, sometimes 14, occasionally nothing at all because half the industry works off a handshake and an invoice. Longer answer: the notice period is the least important part of leaving. The timing around BAS and payroll, and what you secure before you send the email, matter far more. Here's the full picture.

‍

Step one: find out what you actually agreed

Dig out the engagement letter (or the email thread that stood in for one). You're looking for three things: the notice period, any minimum term, and, most important, what happens on exit: file handover, subscription transfer, final invoicing. If there's no written agreement at all, no contractual notice applies, but giving a professional two to four weeks is both decent and pragmatic, because you want cooperation during handover, not spite.

If the letter has a notice period buried in it, honour it. A month of overlap fees is cheap insurance for a clean file transfer, and disputing $600 with someone who controls your Xero access is a tactical masterpiece nobody should attempt (we covered what happens when it goes wrong in my bookkeeper won't give me my Xero file back).

‍

Step two: time it around the compliance calendar

The notice date matters less than the cutover date. Three timing rules:

Never cut over mid-BAS-quarter if you can avoid it. The cleanest handover point is just after a BAS is lodged: the old bookkeeper finishes the quarter they know, the new one starts fresh. Cutting over three weeks before a deadline means the new provider inherits a quarter of someone else's coding at speed. Deadlines are all in the Sydney BAS deadline guide.

Respect the payroll cycle. The switch should land between pay runs, with year-to-date balances confirmed, so nobody's pay is late and super timing (now a per-payday, seven-business-day matter under the 2026 rules) never slips. A missed pay run during handover is the one error your staff will remember forever.

End of month beats mid-month. Reconciliations close cleanly, reports draw a line, and the new provider's first month is a whole month.

‍

Step three: what to secure before you send the notice

Before the email goes: confirm you have admin access to your own Xero file, export the key reports (P&L, balance sheet, aged receivables and payables, payroll summaries), and locate the payroll records and any documents held outside Xero. None of this is paranoia; it's the difference between a handover you control and one you hope for. Then line up the new provider so they can run the transition, which good ones do as standard: contacting the outgoing bookkeeper, collecting the file, checking the state of things. Ours handles the whole relay as part of switching, and if the file turns out to be an archaeological site, a books catch-up resets it.

‍

The notice email

Keep it to five sentences, warm and unambiguous:

"Hi [name], we've decided to move our bookkeeping to a new provider from [date]. Per our agreement, this email is our [X days'] notice. Could you please transfer the Xero subscription to [email], confirm all lodgements to date, and send any records you hold by [date]. Our new provider, [name], will contact you to coordinate the handover. Thanks for your work with us, and please send through your final invoice."

No grievance list, no essay. If the relationship failed badly enough to leave, the email is not the venue for the retrospective. The professional exit protects the thing you actually need: their cooperation for the next 30 days.

‍

What good looks like on the other side

The point of leaving is landing somewhere better, so use the interviews well: the questions to ask a Sydney bookkeeper guide covers the substance, and insist on three exit-proofing terms in the new engagement: your subscription (or transfer-on-exit in writing), your admin access always, and handover included, not billable. A provider who agrees to those without flinching is telling you they plan to keep you by being good, not by holding the keys. That's the standard on our monthly bookkeeping engagements for clients everywhere from Cronulla to Chatswood.

FAQ

Is there a standard notice period for bookkeepers in Australia?

‍No industry standard exists; it's whatever the engagement letter says, most commonly 14 to 30 days. With no written agreement, no contractual notice applies, though two to four weeks is professional practice.

Do I have to pay out the notice period if I stop using them immediately?

‍If the agreement specifies notice, expect to pay fees for that period whether or not you use the services. It's usually worth paying regardless to keep the handover cooperative.

When is the best time to switch bookkeepers?

‍Just after a BAS lodgement, between pay runs, at a month end. The worst time is the fortnight before a BAS deadline with payroll mid-cycle.

What if my bookkeeper reacts badly to the notice?

‍Most don't; it's a normal commercial event. If access suddenly tightens or the file goes hostage, the escalation path in our Xero file guide resolves it, and registered agents have professional conduct obligations that strongly discourage games.

Should I tell them why I'm leaving?

‍Optional. A one-line reason is courteous if the relationship was decent; a detailed critique helps nobody during a period when you still need their cooperation.

How long does the actual handover take?

‍With cooperation, about a week: access transfer, report exports, a status check on lodgements, and payroll balances confirmed. The notice period is usually longer than the work requires.
