Bookkeeper Mosman & Registered BAS Agent Services
Bookkeeper Mosman Clear Books. Strong Systems. Local Accountability.
Your bookkeeping should do more than record transactions. It should give you financial records you can understand, rely on and use to run your business.
My Great Bookkeeper has a firmly established home office in Mosman, NSW and provides professional bookkeeping and Registered BAS Agent services to businesses throughout Mosman, Sydney's Lower North Shore and across Australia.
We look beyond individual transactions and connect the full bookkeeping story β bank reconciliations, customer invoices, supplier bills, payroll, GST, supporting documents and the financial reports you rely on.
Whether your books are already running well, need a stronger system or have become difficult to trust, we start by understanding how your business actually works and where the records need attention.
Our Mosman home office is our established business base. Most bookkeeping is completed securely online, and local meetings can be arranged in Mosman or elsewhere on the Lower North Shore by appointment.
BAS and IAS preparation and lodgment are separate Registered BAS Agent services rather than simply being bundled into ordinary bookkeeping time.

What Does a Bookkeeper Cost in Mosman?
The cost of bookkeeping depends on the amount of work actually happening behind the business. A smaller Mosman business with relatively simple transactions may need light recurring support, while a growing business with payroll, supplier bills, customer accounts, GST and regular BAS obligations may need considerably more bookkeeping time.
My Great Bookkeeper charges for the actual bookkeeping work completed. There are no hours to use up, and the level of support can change as your business changes.

See our current bookkeeping fees and how ordinary recurring bookkeeping, BAS, IAS and other professional services are charged.
If you are comparing bookkeeping costs in Mosman or across the Lower North Shore, this is the quickest place to see how our pricing works.
View Bookkeeping FeesEstimate Your Bookkeeping Hours
Transaction volume is only part of the calculation. Payroll, supplier bills, customer accounts, reconciliations, software systems and the amount of support you want can all affect the time required.
Our bookkeeping hours estimator gives you a closer look at the likely recurring bookkeeping workload before we formally scope your business.
Estimate My Bookkeeping HoursExplore Our Bookkeeping Stages
Nurture, Learn, Grow, Thrive, Lead and Custom show how the bookkeeping workload can change as a business becomes larger, busier or more complicated.
These stages are guides to ordinary recurring bookkeeping support rather than fixed packages or prepaid blocks of time.
Explore Bookkeeping StagesSome Work Sits Outside Ordinary Recurring Bookkeeping.
BAS and IAS preparation and lodgment are separate professional services from the ordinary recurring bookkeeping hours used to maintain your accounts.
If your accounting file already contains historical problems, bookkeeping clean-up, catch-up, reconstruction or rectification work is separately scoped because the amount of investigation required can vary significantly.
Additional work is discussed and scoped with you before it proceeds. You know what is being added and why rather than receiving surprise extras later.
Bookkeeping Support From Our Established Mosman Business Base
My Great Bookkeeper has a firmly established home office in Mosman, NSW. Most bookkeeping is completed securely online, allowing us to support businesses throughout Mosman, the Lower North Shore and across Australia. Our Mosman home office is not used as a client meeting location, but local meetings can be arranged in Mosman or elsewhere on Sydney's Lower North Shore by appointment.
Looking for a Bookkeeper in Mosman? Start With the Questions Business Owners Actually Ask.
If you are looking for a local Mosman bookkeeper, Registered BAS Agent, Xero support or someone to finally get the books under control, these are some of the questions worth asking first.
Do you actually have an office in Mosman?
Yes. My Great Bookkeeper has a firmly established home office in Mosman, NSW.
We support businesses throughout Mosman and Sydney's Lower North Shore while also working with businesses throughout Australia using secure cloud-based bookkeeping systems.
Being based in Mosman gives our local clients a genuine local presence while still allowing us to use modern bookkeeping systems efficiently.
Do you outsource your bookkeeping work?
No. We do not outsource our bookkeeping work to external bookkeeping providers.
All bookkeeping work is completed by a member of the My Great Bookkeeper team, working directly within our systems, procedures and established bookkeeping processes.
Work remains in-house and is subject to full supervision at all times.
Your financial records are not handed to an unrelated bookkeeping company or anonymous processing provider. My Great Bookkeeper remains responsible for the work completed for your business.
This gives our clients continuity, accountability and confidence that the people working on their books are part of the same team responsible for looking after them.
Are you a Registered BAS Agent in Mosman?
Yes. My Great Bookkeeper provides Registered BAS Agent services alongside professional bookkeeping support.
This can include BAS and IAS preparation and lodgment, GST-related bookkeeping, payroll-related BAS services and other services within the permitted scope of our BAS Agent registration.
Our BAS Agent Registration is 26110827.
Can you look after both my bookkeeping and BAS?
Yes.
We can manage your recurring bookkeeping and, where agreed, prepare and lodge your BAS or IAS as a separate Registered BAS Agent service.
Having the bookkeeping and BAS process connected can help identify unreconciled accounts, missing documents, GST issues or unusual balances before an activity statement is lodged.
BAS and IAS preparation and lodgment are separate from ordinary recurring bookkeeping fees.
Do you provide Xero bookkeeping for Mosman businesses?
Yes.
We provide Xero bookkeeping support including bank reconciliation, transaction processing, accounts payable, accounts receivable, payroll, GST coding, reporting and bookkeeping system improvements.
We also work with MYOB and specialist business systems such as Halaxy where they form part of the bookkeeping workflow.
The software is only one part of the job. Our focus is making sure the information flowing through it is accurate, reconciled and useful.
What if my Xero or MYOB file is already a mess?
That is not a reason to avoid calling us.
A significant part of professional bookkeeping is working out why the accounting file no longer agrees with what actually happened in the business.
We can investigate unreconciled transactions, incorrect coding, historical balances, duplicated transactions, payroll issues and other bookkeeping problems.
Catch-up, clean-up and reconstruction work is normally scoped separately from ordinary ongoing bookkeeping because the amount of investigation required can vary.
What kinds of Mosman businesses do you work with?
We work with a wide range of Australian small and medium businesses.
This includes professional and service businesses, medical and allied health practices, consultants, trades and construction businesses, hospitality businesses and growing businesses with employees and more complicated financial workflows.
We do not assume that two businesses need the same bookkeeping simply because they operate in the same industry.
We look at how your business actually works, including transaction volume, payroll, systems, suppliers, customers and the level of support you require.
Do you work with businesses across the Lower North Shore?
Yes.
From our established Mosman home office we support businesses throughout Mosman and the Lower North Shore, including Neutral Bay, Cremorne, Cremorne Point, Cammeray, North Sydney, Kirribilli, Milsons Point, McMahons Point, Wollstonecraft, St Leonards, Crows Nest and Artarmon.
Because our bookkeeping systems are cloud-based, being one suburb further away does not change the quality or regularity of the bookkeeping support.
Do I need to come to your Mosman home office?
No. Our Mosman home office is our firmly established business base, but it is not used as a client meeting location.
Most bookkeeping work is completed securely online, which allows us to work with you regularly without unnecessary travel, paperwork or disruption to your business day.
If you would prefer to meet in person, we can arrange to meet locally in Mosman or elsewhere on Sydney's Lower North Shore by appointment.
What matters is that your books are current, reconciled and properly supported β and that you have someone available when something needs attention.
Can you work with my accountant or tax agent?
Absolutely.
Your bookkeeper and accountant have different roles, and good financial records can make your accountant's work much easier.
Where appropriate, we can work with your accountant or tax agent so information is available when required and responsibilities remain clear.
How much bookkeeping support will my business need?
It depends on the business.
Transaction volume matters, but it is not the only factor. Payroll, supplier bills, customer accounts, business systems, reconciliations and the amount of contact or explanation you prefer can all change the amount of bookkeeping time required.
That is why we do not try to squeeze every Mosman business into the same package.
See Our Bookkeeping StagesHow do I get started with a Mosman bookkeeper?
Start by telling us what is happening.
You do not need to know exactly what service you need, and you do not need to diagnose the bookkeeping problem yourself.
Tell us what feels behind, confusing, time-consuming or simply not quite right.
From there, we can work out the sensible next step.
Tell Us What Is Happening in Your Books.
You do not need to arrive with the answer. That is what the first conversation is for.
