Payroll and workforce management
Paying people correctly and on time is a legal duty and a trust issue. How Australian payroll works end to end: awards, timesheets, Single Touch Payroll, superannuation, leave, rostering and the systems that keep it accurate as the team grows.
- Roster: Plan hours against demand and award rules.
- Record time: Timesheets or clock-ins, approved by a supervisor.
- Interpret: Apply award rates, penalties, allowances and leave.
- Pay and report: Pay staff, issue pay slips, report via STP.
- Remit: PAYG withholding, super guarantee, payroll tax if applicable.
- Reconcile: Check payroll against the ledger and fix errors fast.
Payroll looks like an administrative chore, but it is where several legal systems meet: the Fair Work Act and awards decide what people are owed, tax law decides what you withhold and report, superannuation law decides what you contribute and when, and state law adds payroll tax above a threshold and workers compensation premiums. Getting it right every fortnight, for every person, is the minimum employees expect.
Workforce management is the wider discipline around payroll: rostering to demand, tracking time and leave, managing costs and making sure the right people are in the right place. This article explains how the pieces fit, what good systems look like, and when to keep payroll in-house versus outsource it.
Why it matters
Payroll is usually the largest single cost in a service business and the one with the least tolerance for error. A late or wrong pay damages trust faster than almost anything else an employer can do, and systematic errors compound: a small misinterpretation of an award repeated across twenty staff for three years becomes a serious underpayment with interest and potential penalties. Well-run workforce management also drives profit, because labour rostered to actual demand rather than habit is often the biggest margin improvement available to a growing business.
What a compliant pay run must do
Each pay run must calculate gross pay according to the award or agreement and contract: ordinary hours, overtime, penalty rates, allowances, casual loading and any leave taken. It must withhold the right PAYG amount based on each employee’s tax file number declaration, calculate the superannuation guarantee on ordinary time earnings, and produce a pay slip within one working day of payment that shows the required details. The pay event must be reported to the ATO through Single Touch Payroll (STP) on or before pay day.
Superannuation must be paid to each employee’s chosen fund by the quarterly deadlines at a minimum; many businesses now pay it with each pay run, and the rules are moving in that direction, so check the current requirement with the ATO. Late super attracts a charge that is not tax-deductible. If your total Australian wages exceed your state’s payroll tax threshold you must also register with the state revenue office and lodge returns. Thresholds and rates differ by state and change over time.
- Gross pay calculated to the award, agreement and contract, including penalties and allowances.
- PAYG withholding based on current ATO tax tables and each employee’s declaration.
- Superannuation guarantee at the current rate on ordinary time earnings, paid by the deadline.
- STP report lodged with the ATO on or before each pay day.
- Pay slips issued within one working day; records kept for seven years.
- Payroll tax registration and returns once state thresholds are exceeded.
Choose how payroll gets done
A business with two or three staff on simple hours can run payroll in accounting software in half an hour a fortnight. Once you have casuals on varied rosters, multiple awards, allowances or more than about ten people, award interpretation becomes the hard part and errors multiply. At that point the options are dedicated payroll software with award interpretation built in, a bookkeeper or accountant who runs payroll for you, or a managed payroll service that owns the whole process including compliance updates.
The decision is about risk and time, not just price. Ask who is responsible for keeping award rules up to date, who checks the first pay after every rate change, and what happens when someone resigns and needs a final pay calculated with leave balances. Many growing businesses land on a hybrid: cloud payroll software with award rules, operated by an external provider, with the owner approving each run. SMBH Consulting’s recruitment and payroll service works this way for small and mid-sized Australian employers.
In-house software
- Lowest cash cost
- Owner or admin must learn award rules
- Good for simple, stable rosters
- You carry the compliance risk
Bookkeeper or accountant
- Moderate cost per run
- Shares the compliance load
- Depends on their award expertise
- Good up to a few dozen staff
Managed payroll service
- Fixed fee per employee
- Provider owns rules and updates
- Scales with casuals and awards
- Owner still approves each run
Rostering, time and leave: the inputs that decide accuracy
Most payroll errors are input errors. Paper timesheets filled in from memory on Friday afternoon, rosters that ignore minimum shift lengths or break rules, and leave requests approved by text message all produce wrong pays. A rostering and time-and-attendance system that knows the award, lets staff clock in on a phone or tablet, routes approvals to a supervisor and feeds payroll directly removes most of the problem.
Rostering is also a profit lever. Build rosters from forecast demand (bookings, sales by hour, jobs scheduled) rather than copying last week. Watch the wage cost as a percentage of revenue by day and shift. Give staff visibility of rosters in advance, respect the award’s notice and consultation rules for changes, and track leave balances so you are not surprised by a large accrued liability when someone resigns.
Know the true cost of an employee
The salary or hourly rate is only part of the cost. Superannuation guarantee, workers compensation premiums, payroll tax above the threshold, paid leave and public holidays for permanent staff, uniforms, tools, training, software seats and the time spent managing them all add up. For budgeting and pricing, work out a loaded cost per productive hour for each role, then use it in quotes and in the decision about whether a new hire pays for itself.
Loaded cost per hour = (Wages + Super + Workers comp + Payroll tax + Leave + Other on-costs) ÷ Productive hours
- Wages
- Annual gross pay including expected overtime and penalties.
- Super and on-costs
- Superannuation guarantee, workers compensation premium, payroll tax if applicable, equipment and training.
- Leave
- The cost of paid annual, personal and public holiday time when no work is produced.
- Productive hours
- Hours actually available for billable or output work after leave, training and admin.
How to set up payroll that scales
- Confirm awards and classifications For every employee, written on their file. This is the foundation every calculation rests on.
- Register and connect with the ATO PAYG withholding, STP-enabled software, and superannuation payment through a clearing house or your software.
- Choose the operating model In-house, bookkeeper or managed service based on headcount, award complexity and your appetite for risk.
- Put rostering and time capture in place A system that knows the award, captures real hours and routes approvals before payroll.
- Document the pay-run procedure A checklist: approve timesheets, review exceptions, run, check against last period, pay, lodge STP, file reports.
- Set the remittance calendar Super deadlines, PAYG payment dates with your BAS, payroll tax returns, and workers compensation renewal.
- Reconcile and review monthly Payroll to general ledger, super paid versus accrued, leave liability, and wage cost as a percentage of revenue.
Real-world example
An Adelaide fabricator outgrows its spreadsheet
Torrens Fabrication in Adelaide has grown from four to fourteen staff under the Manufacturing Award: welders on day shift, two on afternoon shift, three casuals and an office manager. Payroll is still a spreadsheet the owner, Luca, fills in from paper timesheets on Thursday nights. When a welder queries his afternoon-shift loading, Luca realises he has been applying the wrong penalty for eight months across three people.
He back-pays the shortfall, then moves to cloud payroll software with the award built in, adds tablet clock-ins at the workshop door with supervisor approval, and engages a payroll provider to run each fortnight while he approves it from his phone. Super is now paid every pay run, STP lodges automatically, and the monthly report shows wage cost against revenue by shift. He uses that data to drop the afternoon shift to three days a week, which saves more than the provider costs, and reclaims his Thursday nights.
Common mistakes
- Flat rates that ignore penalties Paying everyone a round hourly figure "to keep it simple" usually underpays weekend and evening work. Let software apply the award.
- Paying super late The super guarantee charge is punitive and not deductible. Pay with each pay run or set hard reminders for the quarterly deadlines.
- Timesheets from memory Paper filled in on Friday afternoon is the root of most disputes. Capture time as it happens and have a supervisor approve it.
- Ignoring payroll tax as wages grow State thresholds arrive quietly. Check your state’s threshold each year and register as soon as you cross it.
- Nobody checking the first pay after July Award rates and the super rate often change on 1 July. Review the first pay run after the change line by line.
- No one else can run payroll If the only person who knows the process is sick, staff do not get paid. Document the procedure and have a backup.
KPIs to track
- Payroll accuracy Share of pays with no correction needed. Target above 99%; every correction should be traced to its cause.
- On-time payment and lodgement Pays, STP reports and super contributions made by their deadlines. Target 100%.
- Wage cost as a percentage of revenue Tracked weekly or monthly, by site or shift. The right range depends on your industry; the trend is what matters.
- Leave liability Dollar value of accrued annual and long service leave. Growing faster than headcount signals people are not taking leave.
- Payroll hours per pay run Owner and admin time spent each cycle. A rising figure is the signal to change systems or outsource.
Frequently asked questions
What is Single Touch Payroll?
STP is the ATO’s system for reporting wages, PAYG withholding and superannuation information each time you pay staff, directly from STP-enabled payroll software. It replaces the old annual payment summaries; employees see their income statement in myGov.
When does superannuation have to be paid?
At minimum by the quarterly due dates, into the employee’s chosen fund, at the current superannuation guarantee rate. Rules are moving toward paying super at the same time as wages, so check the current requirement on the ATO website.
Do I pay super for casuals and contractors?
Casuals, yes, on their ordinary time earnings. Contractors paid mainly for their labour may also be entitled to super even with an ABN. Use the ATO’s decision tool if unsure.
How often should I pay staff?
Awards set the maximum interval, typically weekly or fortnightly, and your contract should state the frequency. Fortnightly is the most common choice for small businesses; monthly is generally only used for award-free salaried staff where the award allows.
What records do I have to keep?
Time and wages records, pay slips, leave records, super contributions, tax declarations and employment details, kept for seven years and available to the employee or a Fair Work inspector on request.
Key takeaways
- Payroll is where Fair Work, tax, super and state obligations meet; every pay run must satisfy all of them.
- Input quality decides output accuracy: fix rostering and time capture before you blame the software.
- Choose in-house, bookkeeper or managed payroll on risk and time, not just price.
- Pay super on time and review the first pay run after every July change.
- Know the loaded cost of each role and roster to demand; labour is your biggest profit lever.
