You've drafted the email four times. You've deleted it four times. Meanwhile Boring Barry has taken nine days to reply to a one-line question, billed you 0.3 hours for a sigh and described your overdue BAS as "nearly there". Leaving your Sydney bookkeeper is a twenty-minute job that most owners put off for a year, mainly because nobody has told them what order to do it in. Here is the order.
Published: November 2026
This guide covers the exit itself: when to do it, what to lock down first, what to say and what to ask for. The full move to a new provider is covered step by step in how to change your Sydney bookkeeper.
Not every slow week is a reason to leave. But some things are.
One of those, once, is a conversation. Three of them, regularly, is a pattern. If you're not sure where yours sits, take the Roast-O-Meter quiz and see where they land. Then come back.
Find your engagement letter or the email where you agreed terms. You are looking for three things: the notice period, any fees due on exit and what it says about handing back records. Many small bookkeepers work on a month's notice or none at all. Some have nothing in writing, which makes this step short.
If you can't find anything, our guide on how much notice to give your bookkeeper will tell you what normal looks like. If the terms are unclear or there is money in dispute, get legal advice before you send anything.
Don't resign from a bookkeeper into a vacuum. Payroll still has to run next week and the BAS is still due. Have the next arrangement agreed, with a start date, before the current one ends. A new bookkeeper can review the file on read-only access while the old one is still in place, which also tells you how much cleanup you are walking into.
That is the default on our side. We look at the file, quote a fixed monthly figure and agree a start date, so your monthly bookkeeping in Sydney carries on without a gap.
This is the step people skip, and it is the one that causes the awkwardness. Before the email goes, check that the business, not the bookkeeper, controls each of these.
None of this is hostile. It is your business and these are your records. Barry may feel differently and start alphabetising in protest, but that is a Barry problem.
Short, polite, specific. No list of grievances, no apology essay. You are ending a commercial arrangement, and you would like your things back. Here is a version you can use.
Subject: Ending our bookkeeping arrangement
Hi [Name],
Thanks for your work on our books. We've decided to move our bookkeeping to another provider, and I'd like to end our arrangement with you from [date], in line with the notice in our agreement.
Before then, could you please:
From [date], [new provider] will take over. I'll remove system access on that day.
Thanks again,
[Your name]
That is the whole thing. If they reply with questions, answer them. If they reply with a guilt trip, you have confirmed your decision.
If your new bookkeeper will lodge your BAS, they need to be linked to your business with the ATO, and they can't do that on their own.
Rule: The ATO's agent nomination process applies to all types of entities with an ABN, excluding sole traders. When you engage a new registered tax agent, BAS agent or payroll service provider, you must nominate them in Online services for business before they can access your accounts and act for you. The ATO's steps note that you will need the agent's registered agent number, and its guidance to agents states that the agent can't complete the nomination for you.
What to do: ask your new provider for the details you need, log in to Online services for business and complete the nomination. If you have never used Online services for business, set it up now, because it takes longer than the nomination itself. Then ask your new provider to confirm the link has gone through and that the previous agent no longer appears against your accounts.
On our side, BAS lodgement is done by a registered BAS Agent once the nomination is in place.
A clean handover is a list, not a meeting. At a minimum you want:
The full version is in our bookkeeper handover checklist. If the old bookkeeper drags their feet on returning the file, read my bookkeeper won't give me my Xero file back.
On the agreed date, remove the old bookkeeper as a user in Xero, payroll, the bank and every connected app. Change any shared passwords. Update the contact details the ATO and your bank hold if theirs were on file. It takes ten minutes and it is the difference between "former bookkeeper" and "person who can still see my payroll".
There is no perfect date, and waiting for 30 June is a habit, not a rule. A few practical points:
They often are, which is usually why you're leaving. A file that is months behind needs a one-off tidy before normal monthly work can start. Our catch up on overdue books service brings it current at a fixed price, then hands it to the weekly cycle.

How do I leave my bookkeeper politely?
Send a short written notice that thanks them, gives the end date in line with your agreement and lists what you need back: the file brought up to date, outstanding lodgements confirmed, records returned and a final invoice. Keep reasons out of it unless they ask.
How much notice do I need to give my bookkeeper?
Whatever your engagement letter or written terms say. Many small arrangements run on a month or less. If nothing is in writing, reasonable notice and a clear handover date is the usual approach. Get legal advice if there is a dispute.
Can I leave my bookkeeper in the middle of a BAS quarter?
Yes. Either the current bookkeeper lodges the quarter before leaving, or the new one takes over with enough time to review it. What matters is that one of them is clearly responsible for the lodgement.
What should I get back from my old bookkeeper?
Up-to-date reconciliations, a list of anything unfinished, copies of lodged BAS with workings, payroll and super records, any ATO correspondence and control of every system connected to your books.
Do I have to tell the ATO I've changed bookkeepers?
If the new bookkeeper will lodge for you as a registered agent and your business is not a sole trader, the ATO requires you to nominate them in Online services for business before they can act. The agent can't do the nomination for you.
What if my bookkeeper holds my Xero subscription?
Ask them to transfer the subscription to you before the arrangement ends. If they refuse or go quiet, contact Xero support and ask what your options are as the business owner.
Should I line up the new bookkeeper before giving notice to the old one?
Yes. Agree the scope, price and start date first, so payroll and lodgements continue without a gap.
What does it cost to switch bookkeepers?
Usually the old bookkeeper's final invoice, any cleanup the file needs and the new monthly fee. A fixed monthly price is easier to plan around than an hourly bookkeeper at $80 to $150 an hour with no agreed scope.
