Before approving a correction plan, an Australian employer should require period-correct coverage and classification evidence, documented sampling and expansion rules, employee-level calculations, independent quality assurance and proof of payment and control fixes.[1][3] The audit should also test the records the Fair Work Act already requires the employer to keep, because gaps in those records shift the burden of proof onto the employer.[7]

Start with the statutory record baseline
Every payroll audit rests on records the law already requires. Under the Fair Work Act, an employer must make, and keep for 7 years, the employee records prescribed by the regulations, and must not make or keep a record it knows is false or misleading.[7] Payslips must be given within one working day of paying an employee for work performed.[7]
The Fair Work Regulations set the minimum content of those records:[8]
- the employer’s and employee’s names, the ABN, the start date, and whether employment is full-time or part-time and permanent, temporary or casual;
- the rate of pay, gross and net amounts paid and any deductions;
- hours worked for casual or irregular part-time employees paid by time;
- details of any incentive payment, bonus, loading, penalty rate or allowance;
- overtime hours each day, or start and finish times for overtime, where a penalty or loading applies; and
- leave taken, leave balances and any agreement to cash out leave.
Records must be legible, in English and readily accessible to a Fair Work inspector.[8] Ask the reviewer to report which of these record types are missing or incomplete for each cohort and period. Where a required record was not made, kept or made available, the employer may bear the burden of disproving an underpayment allegation in court proceedings.[7]
Write an approval-ready statement of work
- Require in every engagement: defined entities, instruments, employee cohorts, pay elements and periods; specified source records; documented assumptions and exceptions; employee-level outputs; quality assurance; acceptance criteria; and named remediation owners.[1][3]
- Set according to risk and purpose: the review model, look-back period, sampled or full-population testing, significance threshold and correction timetable. The cited guidance gives no universal values for these engagement settings.[1][3]
The scope should name each legal entity, location, applicable instrument, contract population, employment type, workforce cohort, pay element and historical review period. Any exclusion should be explicit.[3]
Required inputs should include employee and classification histories, contracts and variations, rosters, actual start, finish and break records, leave data, transaction-level payroll data, payslips, superannuation records, allowances, deductions, termination calculations and manual or off-cycle payments.[3] Because the statutory retention period is 7 years, records older than that may not exist; the statement of work should say how the review treats periods where records are no longer held.[7]
Require period-correct coverage and classification evidence
Make a cohort-by-cohort coverage matrix a deliverable. It should identify the NES, applicable modern award or enterprise agreement, employment contract, annualised-wage or individual flexibility arrangement, superannuation obligations and relevant long-service-leave legislation. Superannuation analysis should remain distinct from wage-entitlement calculations.[2]
For each historical pay period, require the reviewer to identify the instrument version, replacement or variation and the rate then in force. Applying present rates retrospectively can produce incorrect correction figures.[3]
Award coverage should be tested against the instrument’s coverage clause and the employer’s actual industry or the employee’s actual occupation.[2][3] Classification evidence should address duties performed, skills and qualifications used, supervision and responsibility—not merely job titles or payroll labels.[2][3]
- Separate casual, part-time and full-time employees, juniors, apprentices, trainees, labour-hire workers and possible employee–contractor misclassification cases.[2]
- For each cohort, map base rates, ordinary hours, overtime, penalties, allowances, loadings, leave, public holidays, deductions, termination entitlements and contractual benefits above the statutory floor.[2][3]
- Link every modelled rate and entitlement to the relevant period-specific award or agreement text.[3]
- Record unresolved interpretations, alternatives and financial sensitivity, then assign an escalation owner before approving calculations.[3]
Set sampling and expansion rules before testing
A sampled review does not establish that every historical payment was correct. Require a written selection rationale covering risk signals, cohort representation, selection method, significance threshold and known limitations.[3]
Complaints, payroll system changes, acquisitions, restructures, incomplete award variations, weak time records and anomalies identified by payroll or internal audit can inform the sample.[3]
A retrieval test might include a current employee, a terminated employee, a salaried employee and an hourly employee with overtime or allowances.[1] This can test whether key records are available, but it is not a universally sufficient audit sample; sample size and thresholds must be set for the engagement.[1][3]
Write the expansion rules into the statement of work:
- If a sample reveals a configuration or interpretation error, test every employee and pay period affected by that rule.[3]
- Consider extending testing to adjacent cohorts at other sites or entities governed by the same rule.[3]
- Use full-population testing where the population is small, calculations can be automated or sampled testing exposes a systemic fault.[3]
Compare payroll compliance audit models
Choose the model according to whether the engagement must identify warning signs, quantify historical exposure, test upcoming payments or combine remediation with continuing monitoring.
Payroll health check
- Tests: selected payroll records and controls.[1]
- Limit: it can identify gaps but may not quantify historical exposure.[1]
- Suited to: initial screening after growth, added awards or process changes.[1]
Full reactive audit
- Tests: historical payments to identify discrepancies, causes and remediation exposure.[1][6]
- Limit: it requires more work than a payroll health check, although E-Payoffice positions it as providing a stronger basis for remediation.[1]
- Suited to: complaints, repeated adjustments, uncertain award coverage, acquired payroll data or regulator contact.[1]
Proactive pay-run testing
- Tests: upcoming payments before release.[6]
- Limit: one compliant pay cycle can miss problems emerging across neighbouring or historical periods.[6]
- Suited to: pre-payment testing of payroll rules and calculations.[6]
Software monitoring
- Tests: repeat pay runs at scale through automated monitoring.[6]
- Limit: results depend on accurate source data, while ambiguous clauses still require human judgement.[6]
- Suited to: recurring pay-run assurance.[6]
Hybrid approach
- Tests: automated payroll outputs alongside specialist interpretation and configuration validation.[6]
- Limit: automation still relies on accurate source data and specialist judgement for ambiguous provisions.[6]
- Suited to: employers needing monitoring, interpretation and remediation support.[6]
Compare named providers on the same dimensions
A payroll platform, audit service and workplace consultancy should not be treated as equivalent. Compare each candidate against the required scope, evidence and acceptance criteria.
E-Payoffice
- Disclosed service: Australian payroll audit support covering records, STP, awards, agreements, software controls and remediation evidence.[1]
- Stated market: Australian businesses with 20–500 employees.[1]
- Delivery: a Sydney-based team and Microsoft Azure hosting in Sydney and Melbourne.[1]
Australian Workplace Strategies and Strobe
- Disclosed service: period-correct entitlement models, findings, quantification and remediation options.[3]
- Stated market: Australian employers seeking a single review or ongoing assurance.[3]
- Delivery: Strobe is offered as an auditable repository covering multiple years.[3]
ResolveHR
- Disclosed service: workplace advice and a staged wage-remediation process.[4]
- Stated market: managers and business owners, with the consultancy identified as Sydney-based.[4]
- Delivery: its stated process covers identifying underpayments, mapping instruments and classifications, validating data, consulting employees, calculating backpay and implementing ongoing controls.[4]
ClockOn
- Disclosed service: connected rostering, time and attendance, configured award or payroll rules and payroll processing.[5]
- Stated market: the cited page does not state a service area or eligibility criteria.[5]
- Delivery: its checklist records exceptions, resolutions, completion status and reviewer initials.[5]
These descriptions do not support ranking one provider above another. Selection should turn on demonstrated compliance with the statement of work and acceptance criteria.
Reconcile hours, payslips and entitlements
Require a calculation trail following each selected employee from roster and actual time records through line-level payroll transactions and payslips. The reviewer should reconstruct each pay period using the instrument version and rates effective at that time.[2][3]
Reconcile each entitlement separately for each pay period. Aggregated results can conceal errors or imply an overpayment automatically offsets an unrelated shortfall.[3] Where relevant, test:
- start and finish times, unpaid breaks, overtime triggers and spans of hours;
- shifts, evenings, nights, weekends, public holidays, higher duties and missed-break consequences; and
- allowances, leave, loadings and termination payments.[2][3]
Also test whether each payslip was issued within one working day of payment and whether its contents match the payroll record.[7][8] Show superannuation calculations and remittances, PAYG withholding, deductions and payroll reconciliation separately from the wage-entitlement analysis.[1][3]
Document exceptions, uncertainty and root cause
The exception log should identify affected employees, periods and entitlements, evidence, assumptions, alternative interpretations, financial sensitivity, data limitations, testing-expansion decisions and the escalation owner.[3]
Classify each root cause as configuration, interpretation, data capture, management practice or governance failure, and distinguish isolated transactions from broader patterns.[3]
Fictional exception: The weekend penalty rate applied is uncertain because available time records do not establish when the work occurred. Alternative interpretations produce different correction results. Root cause: data capture. Decision: hold the calculation, expand testing to employees governed by the same rule, and escalate the instrument interpretation and missing evidence to the named owner.
Independent quality assurance should reperform selected calculations and test effective-date and public-holiday boundaries, mid-period terminations, rounding, null values and records rejected by the model.[3]
Make the correction pack the acceptance test
Approval should depend on a complete correction pack rather than a headline backpay figure. Require:
- Employee-level calculations: verified results for each affected current and former employee, period and entitlement category, with superannuation, PAYG, applicable interest and related amounts shown separately.[2][3]
- Calculation audit trail: applicable instrument evidence, source data, assumptions, alternative interpretations and financial sensitivity, plus preparer, reviewer and approver details, quality-assurance results and resolved exceptions.[1][3]
- Communication and payment evidence: what happened, affected periods and entitlements, calculation method, payment date and contact channel. Keep each employee’s calculation, approval, communication and payment records together, including documented attempts to contact former employees.[1][3]
- Prospective control repair: corrected rate libraries, rebuilt payroll rules, repaired time capture and approvals, issue-specific exception reports and retesting evidence.[3]
- Accountability: named owners for instrument changes, classification and wage reviews, annualised-wage reconciliations and each outstanding remediation action.[3]
Before changing systems or records, preserve original payroll exports, timesheets, rosters, contracts, payslips, system logs, approvals, correspondence and superseded configurations.[2][3] Corrections should be recorded as new entries rather than by overwriting history, since knowingly keeping a false or misleading record is itself a contravention.[7]
What to confirm with each provider
The provider pages cited here do not publish prices, contract lengths, cancellation rights, service guarantees or independently verified performance results.[1][3][4][5]
- Price, minimum fees and what triggers additional charges
- Contract length, cancellation rights and termination charges
- Exact audit look-back period and included entities, cohorts and pay elements
- Sampling method, significance threshold and full-population expansion rules
- Correction deadlines, service levels and responsibility for delays or incomplete data
- Reviewer qualifications, independent quality assurance and performance evidence
- Access to working papers after completion, consistent with the 7-year record obligation
Make a go, hold or expand decision
- Go: approve corrections and communications when coverage and classification evidence is period-correct, the tested population matches the agreed scope, expansion rules have been applied and employee-level calculations have passed documented quality assurance.[3]
- Hold: pause approval where material data gaps, unresolved interpretations, undocumented assumptions, omitted former employees or unsupported offsets could change the result.[3]
- Expand: extend testing where a configuration, interpretation, time-capture or governance failure may affect adjacent employees, periods, sites or entities governed by the same rule.[3]
Record each unresolved exception, correction payment, employee communication, system fix and retest with an accountable owner, due date and completion evidence.[1][3]
