Outsource Payroll in Australia
Every pay run carries compliance risk. PAYG withholding must be exact. Super must be lodged before the quarterly deadline. STP Phase 2 must be submitted before payslips are issued to employees. Award rates must reflect the current Fair Work instrument — and they change without notice.
Payroll errors are the leading cause of ATO compliance notices for Australian SMEs. Most don't come from intent — they come from manual processes, outdated award rates, and a payroll function managed by someone whose core job is something else.
Aone Outsourcing Solutions manages the complete payroll cycle for Australian small businesses, growing companies, and CPA firms — from wage calculations and award interpretation through to STP lodgement, super payments, and month-end reconciliation, inside your existing Xero, MYOB, or QuickBooks environment. No migration. No disruption. Unlike enterprise legacy providers that require proprietary platform migrations, we manage payroll directly inside your live accounting environment.
Not just automated. Not just manual. Both — working together.
Our AI automatically catches anomalies and streamlines processing, while certified payroll professionals manually review and sign off on every run to eliminate errors before your payslips are issued.
AI-Assisted Processing
Recurring items auto-coded. Award anomalies flagged before processing. Overtime thresholds are checked every run. Duplicate payments stopped before they reached employees.
Human Verification — Every Pay Run
A certified payroll specialist reviews every AI output before finalisation. Award interpretation, termination calculations, and contractor classification require judgment that automation can't replicate.
ATO-Ready Output, Every Cycle
STP Phase 2 lodged. Super paid on time. Fair Work entitlements are correct. Reconciliations complete. Nothing outstanding at year-end — without you tracking any of it.
The Benefits of Outsourced Bookkeeping Services
Payroll Expertise On Demand:
Australian payroll requires ongoing knowledge of Modern Awards, NES obligations, STP Phase 2, and state payroll tax thresholds — all of which are subject to change without notice. Outsourcing puts a certified payroll team behind every pay run, with no gaps in coverage, knowledge, or single points of failure.
Cost Savings:
A full-time payroll officer costs AUD $65,000–$80,000 in base salary before super, leave loading, software, and training. Our managed payroll services deliver the same outcome at a fixed monthly rate — with an independent quality reviewer built in. Most businesses save 40–50% against the true cost of in-house payroll.
Scalability:
More headcount, more states, more award classifications — payroll complexity grows with your business. Outsourced payroll scales with you immediately, without a hiring cycle or the dead cost of overstaffing.
ATO & Fair Work Compliance:
STP Phase 2, superannuation deadlines, payroll tax returns, and Fair Work entitlements are all part of the ongoing compliance calendar. Everything is done on time, nothing is forgotten, and records are always audit-ready. With Fair Work stepping up wage theft audits, a single award misclassification or late quarterly SGC payment can trigger severe financial penalties — making day-one compliance a foundational business metric, not an afterthought.
Efficiency:
Our automated AI layer flags award anomalies instantly and accelerates processing, while a certified payroll specialist manually signs off on every run — faster pay cycles, more errors caught pre-payment, and more time for your in-house team to focus on growth.
Data Security:
Payroll data is among the most sensitive data your business holds. We operate under 256-bit encryption, role-based access control, two-factor authentication, mandatory NDAs, and a no-local-storage policy — fully aligned with Australia's Privacy Act 1988.
AI-Assisted Payroll Processing. Expert-Verified. Every Cycle.
Payroll Setup & Employee Records
We audit your existing payroll structure before the first run — award classifications, TFN declarations, super fund details, leave balances — so records are right from day one, not corrected after the first error.
- Award and employment classification confirmed per employee
- TFN declarations and super fund details verified before go-live
- Leave balances are imported and reconciled from day one
- Contractor vs employee classification reviewed at onboarding
- New starter checklist completed per ATO requirements
Pay Calculations & Payslip Processing
Each pay period is based on the wage rate confirmed in the award, the employment classification, and the agreed wage. Before a payslip is issued, gross pay, PAYG withholding, overtime, shift loadings and allowances are all checked.
- Pay rates, penalty rates, and loadings applied per the relevant Modern Award.
- Paychecks and expense claims approved by the ATO treatment
- Each pay slip is created and issued before payday
- Anomalous and duplicate payments are identified before the payment is made
- AI codes recurring items; specialists review each output.
STP Phase 2 Lodgement
Mandatory for all Australian employers. We handle the income-type disaggregation, cessation reporting and year-end finalisation — so that all pay events are reported to ATO within 24 hours of the pay run closing.
- STP Phase 2 lodgement within 24 hours of each pay run close.
- Income type disaggregation performed as specified by ATO
- Quarterly figures are reconciled with the figures pre-filled by the ATO
- Lodging of year-end finalisation on time each year
- STP errors are being corrected before the ATO review date.
Superannuation & SuperStream Compliance
As per law changes, the correct rate was calculated, payments were made using SuperStream before each quarterly deadline, fund details were matched, and monthly payroll reconciliation was completed with the payroll register — automatically.
- SGC is computed at the correct rate per employee
- SuperStream payments made before the ATO quarterly deadlines
- Super fund choice managed and documented for employees.
- Quarterly reconciliation to payroll register.
- SGC's liability is flagged before any deadline.
Award & Enterprise Agreement Interpretation
Award misclassification is the most common Fair Work underpayment trigger in Australia. We confirm the applicable Modern Award or Enterprise Agreement for every employee at onboarding — correct classification, correct rates, correct allowances — from the first pay run, not the first audit notice.
- Modern Award confirmed per role and industry
- Penalty rates, overtime thresholds, and loadings applied correctly
- Enterprise agreement provisions interpreted where applicable
- Award updates applied as Fair Work determinations change
- Classification is reviewed when roles or working arrangements change
Leave & Accrual Management
Annual leave, personal leave, long service leave, and parental leave are calculated, recorded, and reconciled every cycle. Leave liabilities reported monthly — so exposure is visible before it becomes a balance sheet problem.
- Accruals calculated per NES entitlements and applicable award
- Long service leave is tracked per state legislation
- Leave is paid at the correct ordinary time rate when taken
- Leave liability is included in every monthly payroll summary
- Balances reconciled against the payroll register quarterly
Payroll Tax Management
Thresholds, rates, and grouping provisions vary by state. We monitor your position across every state where employees are based, prepare monthly and annual returns, and flag exposure before the first liability falls due.
- Payroll tax threshold monitored per state
- Monthly and annual returns prepared and lodged
- Grouping provisions and exemptions assessed
- Threshold breach flagged before liability crystallises
Reconciliation Reports & Payroll Summary
Every pay run produces a complete reconciliation — gross wages, PAYG withheld, super liability, leave accruals, net payments — delivered within 24 hours of cycle close and reconciled to your general ledger before month end.
- Reconciliation delivered within 24 hours of every cycle close
- Monthly summary: gross, tax, super, and net payments
- Payroll reconciled to the general ledger monthly
- PAYG withholding reconciled to BAS each quarter
- Year-end payment summaries were distributed on time
Termination Pay & Final Entitlements
The highest-risk calculation in Australian payroll. We confirm the termination type, calculate any unused leave, redundancy, and payment instead of notice, and correct the withholding treatment — paid on the required day, with STP cessation lodged with the ATO on the same day.
- Termination type is confirmed before any calculation begins
- All unused leave is paid correctly in accordance with NES and the award.
- Genuine redundancy tax treatment applied.
- The final payslip is given on the date of termination.
- STP cessation lodged with the ATO on the day of departure
Salary Packaging & Remuneration Structuring
When implementing salary sacrifice, novated leases, and FBT-exempt benefits, it's important to set them up in a tax-efficient way without risking compliance issues. We handle calculations, FBT record-keeping, and STP reporting to ensure packages are effective.
- Salary sacrifice and novated lease deductions calculated and reconciled
- Identified and documented FBT-exempt benefits as per ATO requirements
- Reportable fringe benefit amounts are included in STP submissions.
- If FBT is reportable, the gross-up calculation will be applied.
Onboarding & Exit Processing
The most typical payroll error is during onboarding and offboarding. We handle both sides of the process: TFN declarations and super choice collection through to final pay, STP cessation, and offboarding reconciliation, all completed within 48 hours.
- TFN declaration and super choice collected and verified on enrolment
- Records closed and final entitlements determined on the day of exit.
- STP cessation to the ATO on the day of departure
- Offboarding reconciliation is done within 48 hours.

Percy
CA Firm Partner
As we grew from 8 to 40 staff, our payroll became too difficult to manage internally, and Aone did all the reclassifications, set up the STP Phase 2 and ensured that everything was compliant — we never had to worry about it.
Noah
For years, we did our own payroll, and Aone took over in a week. Pays get out on time, super gets arranged, and we've got no compliance issues since.
