What to Ask a New Sydney Bookkeeper Before You Sign Anything

Every Barry interviews beautifully. They all have "20 years of experience", they all "love Xero", and they all promise responsiveness with the conviction of a man who will, within six weeks, take nine days to reply "noted" to an urgent email. The interview only works if you ask questions that have verifiable answers. Here are the twelve, with the good answer and the run-away answer for each.

Published: June 2026

‍

The accountability questions

‍

1. "What is your guaranteed response time, and is it in the engagement letter?"

Good answer: a specific commitment, in writing, same or next business day. Run-away answer: "we always get back to people pretty quickly", which is a vibe, not a term. Slow replies are the number one complaint that drives bookkeeper switches, so make it contractual from day one.

‍

2. "Who actually does the work on my file?"

You are often pitched by the principal and serviced by whoever has capacity. Neither model is wrong, but you are entitled to know: who touches the file, who reviews it, and who you message when something is urgent. Run-away answer: vagueness, or visible discomfort at the question.

‍

3. "Walk me through your month. What happens, and when?"

A real operator describes a rhythm without hesitating: weekly reconciliation, payroll on the cycle, AP runs, month-end close by a fixed date, reports by another fixed date. Barry describes "staying on top of things as they come in", which translates to opening your file the week the BAS is due.

‍

4. "What happens when you find a problem in my file?"

The right answer involves telling you promptly, in plain English, with options. The wrong answer involves quietly fixing things without a record, or worse, quietly not fixing them. Files rot in silence; ask how silence is prevented.

‍

The money questions

‍

5. "Is the price fixed, and what exactly does it include?"

A fixed monthly fee with a written scope: which accounts, what volume, payroll for how many, which reports, BAS or not. The run-away answer is an hourly rate with no cap, which is how a five minute email becomes a line item, and how your costs rise precisely when your business gets messier and needs help most. What the Sydney market actually charges at each tier is in the 2026 pricing guide.

‍

6. "What is out of scope, and what does out-of-scope work cost?"

Every engagement has edges. A professional can name theirs instantly and tells you how extras are quoted (fixed, in advance) before work starts. Barry discovers scope boundaries retroactively, on invoices.

‍

7. "What does onboarding cost, and what does it include?"

Taking over a file properly involves reviewing it, fixing what is broken, and documenting how it runs. If the file needs a cleanup, that should be a separately quoted fixed project after they have actually looked at it, not a shrug and an hourly meter. Anyone who quotes a cleanup without opening the file is guessing; the honest version of that first look is exactly what a Free Xero Roast is.

‍

The compliance questions

‍

8. "What are your arrangements for BAS and IAS lodgement?"

BAS services for a fee are regulated: they must be provided through a registered agent, and registration is checkable on the public Tax Practitioners Board register. The good answer names the arrangement clearly and invites you to verify it. The run-away answer is any version of "we just sort of handle it", which is a regulatory problem wearing a polo shirt.

‍

9. "How will you handle Payday Super and the current payroll changes?"

A current practitioner can speak fluently about what is changing: super payable with every pay run from 1 July 2026, the 7 business day window, the clearing house transition, STP finalisation by 14 July. A bookkeeper who looks blank at this question in 2026 has not been reading anything, and your payroll would be their learning environment. The full changeover is summarised in the EOFY checklist.

‍

10. "What do you need from my accountant, and how do you work together?"

The healthy answer describes a clean division: bookkeeper keeps the file current all year, accountant does tax and structure, the two talk directly without routing everything through you. The unhealthy answer treats your accountant as a rival or, stranger, as someone they would prefer never to meet.

‍

The exit questions

‍

11. "If I leave, what do I get and how fast?"

Non-negotiable: you own your data, your Xero subscription should be in your name or transferable to it, and handover to a successor happens within days, professionally. Ask it directly and watch the reaction. A confident professional answers instantly because they keep clients through service, not hostage-taking. Any flicker of "well, the file is on our subscription and there would be an export fee" is a future you will not enjoy.

‍

12. "Can you show me a sample monthly report pack?"

Not a brochure, an actual (anonymised) example of what lands in a client's inbox monthly. You learn more from thirty seconds with a real report than from the whole meeting: is it readable, is it on a fixed date, does it say anything, or is it four default Xero PDFs in a trench coat. If the sample resembles the artefacts catalogued in 13 signs your bookkeeper is secretly Boring Barry, you have saved yourself a year.

‍

Scoring the interview

Tally it honestly. Specific, written, verifiable answers across the board: proceed. Two or three soft answers on minor points: proceed with the engagement letter doing the heavy lifting. Vague on response times, hourly with no cap, fuzzy on lodgement arrangements, or weird about exit: stop, regardless of how good the chemistry felt. Charm is free. Terms are real.

And if you are reading this because your current bookkeeper would fail half these questions, the orderly way out takes about a week and is documented step by step in how to change your Sydney bookkeeper without it getting weird. If you want a second opinion on what they have left behind first, that is what the Free Xero Roast is for.

FAQ

How do I verify a BAS agent registration?

‍The Tax Practitioners Board maintains a public register, searchable by name or registration number. Any provider charging a fee for BAS services should be able to point you to the registered agent arrangement behind the service.

Should a bookkeeper give references?

‍Client references in your industry and size band are reasonable to request. More telling, honestly, are the sample report pack and the written response-time commitment, because references are curated and documents are not.

Is cheapest fine?

‍Cheap with a tight written scope can be fine for simple files. Cheap with vague scope is how you end up paying twice: once for the service, once for the cleanup. Price the total cost of ownership, not the monthly line.

What is a reasonable notice period in a bookkeeping engagement?

‍Thirty days or less, with no lock-in beyond it, is the modern standard. Twelve-month minimum terms exist to protect providers from their own service levels.

Should the Xero subscription be in my name?

‍Ideally yes, or contractually transferable to you on exit at no cost. Subscription custody is the most common practical friction when leaving a bad bookkeeper.

How many bookkeepers should I interview?

‍Two or three, asked identical questions. The contrast does most of the analytical work for you.
