Outsourced bookkeeping services for Australian businesses
Business Avengers provides outsourced bookkeeping for Australian businesses with $10M to $1B in revenue. A named, Australian-managed team runs your accounts payable, receivable, reconciliations and payroll inside your own Xero, MYOB, NetSuite or ERP, for a fixed monthly fee. Most clients are live within a week, and every engagement starts with a 45-day risk-free trial.
What our bookkeeping team handles
Our managed bookkeeping services cover the transactional work that keeps your books accurate and your month-end on time. Your team follows documented processes agreed with you, works to a fixed calendar and reports progress every week, so you always know where things stand. Each area below links to the full service page.
- Accounts payable
Supplier invoices coded, approved and paid on schedule, with statements reconciled every month.
- Accounts receivable
Invoices raised on time, debtors followed up and cash applied, so your aged receivables stay current.
- Bank and balance sheet reconciliations
Every bank, clearing and control account reconciled, with variances explained rather than parked.
- Payroll and Single Touch Payroll reporting
Pay runs, superannuation and STP reporting handled against the right award and Fair Work rules.
- Month-end close
Accruals, prepayments and journals posted to a fixed timetable, so management reports land on time.
- Lodgement-ready workpapers for your registered agent
Clean, reconciled workpapers handed to your registered agent each period, ready for them to review and lodge.
Everything happens inside your own accounting system, under your logins and approval rules. Nothing is moved, exported or rebuilt, and you keep full visibility of every transaction your team touches.
Who outsourced bookkeeping is for
We work with Australian SMEs and corporates turning over between $10M and $1B, where transaction volumes have outgrown a single bookkeeper but a full in-house finance team is expensive to build and keep. Outsourced bookkeeping for mid-sized businesses works best when there are clear processes to run, several people relying on the numbers and a finance lead who wants their time back for analysis.
- SMEs and corporates with $10M to $1B in revenue
- Multi-entity groups that need consistent processes and intercompany reconciliations
- Not-for-profits that need clean records for boards, funders and auditors
- Accounting firms that want reliable back-office capacity for their clients
Clients are based across Australia, from Sydney and Castle Hill to Melbourne, Brisbane and Perth, and every engagement is managed from our Castle Hill, NSW office.
What outsourced bookkeeping costs compared with an in-house team
The true cost of an in-house finance hire is far more than the salary. Super and other employment on-costs, recruitment fees and the management time spent hiring, training and covering leave all add up. When people ask about bookkeeping outsourcing cost in Australia, this is the comparison that matters. The table uses the same 4-person example as our savings calculator. All amounts are in AUD per year.
| Cost item (4 roles) | In-house team | Business Avengers |
|---|---|---|
| Base salaries ($90,000 each) | $360,000 | Included |
| Employment on-costs incl. super (19.3%) | $69,408 | Included |
| Recruitment fees (15% of base salary) | $54,000 | None |
| Management time, leave cover and turnover | Extra, not counted | Covered by your team |
| Total per year | $483,408 | $192,000 |
In this example, a Business Avengers team costs $192,000 a year against $483,408 for the same capacity in-house, a saving of $291,408 or 60%. Your figures will depend on your roles and salaries. See our pricing or run your own numbers in the ROI calculator.
How it works, live in a week
Moving your bookkeeping should not mean months of disruption. Most clients are fully onboarded within one week, and your current team keeps working while we take over. Here is how it works.
- Step 1
Brief us.
One call. Tell us what's broken, what's working and what you need covered. No questionnaire, no lengthy pitch. We map the scope of work with you.
- Step 2
Knowledge transfer.
We spend time with your outgoing team and existing systems to learn your process. This is where we do the heavy lifting, not you or your staff.
- Step 3
Build your team.
We assign a dedicated Avengers team to your account, matched to your size, complexity and accounting software, with a named Australian manager.
- Step 4
Avengers perform.
Your finance function runs on schedule. You review the outputs, not the process, and we handle everything that sits behind the numbers.
Software we work in
We work in your system: no migration, no new tools to learn. Whether you need Xero bookkeeping services, MYOB bookkeeping for an established business or NetSuite bookkeeping across a group of entities, your team already knows the software and works inside your existing setup.
- Xero
- MYOB
- NetSuite
- SAP
- Oracle
- MS Dynamics
- QuickBooks
Security and accountability

Business Avengers is ISO 27001 certified, the international standard for information security management. Access to your systems is controlled, granted only to the people working on your account and removed the moment it is no longer needed.
Every engagement has a named Australian manager who is accountable for your deadlines, your team and the quality of the work. Processes are documented, reviewed and signed off with you, so nothing depends on one person's memory. Read our information security policy.

In-house, local bookkeeper or Business Avengers?
The outsourced bookkeeper vs in-house question usually comes down to cost, continuity and control. A local bookkeeper can suit a very small business, but growing companies tend to need more cover and more oversight than one person can give. Here is how the three options compare.
| Factor | In-house team | Local bookkeeper | Business Avengers |
|---|---|---|---|
| Cost | Salary, super, on-costs, recruitment and management time | Hourly or per-transaction billing that rises with volume | One fixed monthly fee, agreed upfront |
| Cover during leave | Work stops or piles up when someone is away | Usually a single person, so cover is limited | A team, so work continues through leave and turnover |
| Expertise | Limited to the people you hire | General bookkeeping, often for very small businesses | Chartered accountants overseeing every account |
| Scalability | Hire, train and onboard for every increase | Capacity tied to one practice | Scale the team up or down as volumes change |
| Software | Whatever your staff already know | Often limited to one or two packages | Works in your system: Xero, MYOB, NetSuite, ERPs |
| Accountability | Spread across your own managers | Informal, often no documented process | A named Australian manager and documented processes |
