Top 7 Signs Your Payroll Process Is Costing You Money

By Natasha Silveira | 21 September 2026 | 10 min read

Most business owners find out their payroll process is costing them money the hard way: a Fair Work notice, a superannuation shortfall letter from the ATO, or an employee who quietly does the maths on their own payslip and asks a hard question. Payroll costs a small business more than the wages themselves once you count the time, the errors, and the risk sitting behind every pay run. The good news is that the warning signs show up long before the letter does, if you know where to look. Here are the seven we see most often in businesses across Melbourne, Sydney and Hobart, and what each one is actually costing you.

1. You are still calculating award rates and penalties by hand

Modern awards change often, and most carry different rates for ordinary hours, overtime, weekends, public holidays, and allowances. If someone in your business is working these out in a spreadsheet, or worse, from memory, the error rate climbs fast. A single misapplied loading on a Saturday shift does not sound like much. Multiplied across a roster and backdated when it is finally caught, it becomes a real liability.

Spreadsheets also do not update themselves when the Fair Work Commission adjusts minimum award rates each financial year. If nobody owns that update, you are running last year’s rates on this year’s roster without knowing it. The correction, when it eventually happens, usually needs to be backdated to the date the new rate took effect, not the date someone noticed. That backdating is where a small oversight turns into weeks of remediation work and an uncomfortable conversation with staff.

Manual calculation also makes classification mistakes harder to catch. An employee promoted into a higher classification, or one who has picked up duties that trigger a different pay point, needs their rate reviewed at the same time. When that check is not part of the routine, it simply does not happen until someone asks why their pay has not moved.

2. Payroll and your rostering system do not talk to each other

When timesheets, rostering, and payroll live in three different systems, someone has to manually move data between them. That handoff is where hours go missing, penalty triggers get missed, and casual loading gets applied inconsistently between staff doing the same job. It is also where duplicate or forgotten entries creep in, particularly around public holidays and shift swaps.

This shows up clearly at Single Touch Payroll reporting time. If your rostering data and your STP report tell two different stories about hours worked, that mismatch is visible to the ATO the moment it is filed. A one-off mismatch is usually nothing. A recurring one is a sign the systems were never properly connected in the first place, and it is worth fixing before it becomes the reason for a closer look at your reporting history.

3. You have had an underpayment or overpayment in the past year

One correction is a mistake. A pattern of corrections is a process problem. If you have had to fix a pay run more than once in the last twelve months, the underlying cause, whether that is a rate table, a rounding rule, or a manual entry step, is still there waiting to cause the next one. Underpayments carry back-pay and reputational cost. Overpayments are just as expensive: they are hard to recover once someone has spent the money, and clawing them back damages trust.

Recovering an overpayment from a current employee generally needs their agreement to a repayment arrangement, and recovering one from a former employee is harder again. Many small businesses simply write the amount off rather than pursue it, which means the mistake costs money twice: once in the overpayment, and again in the time spent trying to fix it.

Nationally, this is not a small issue. The Fair Work Ombudsman recovered $473 million in wages for close to 160,000 underpaid workers in the 2023 to 2024 financial year alone, and $1.5 billion over the three years to mid 2024. Most of that started as a payroll process issue, not a deliberate act.

4. Superannuation guarantee does not always go out on time

Since November 2021, employers have been required to pay super guarantee at least quarterly, and late payments trigger the superannuation guarantee charge, which is not tax deductible and includes interest and an administration fee. If your SG payments have ever slipped past the due date, even by a few days, that gap is costing you more than the super itself.

The scale of this problem across Australia is significant. The ATO’s own tax gap research estimates the superannuation guarantee gap at $6.2 billion, or around 6 per cent of the total superannuation guarantee employers should be paying, in the 2022 to 2023 year. Most of that gap comes from small and medium employers, not large corporates with dedicated payroll teams.

5. Nobody can tell you what an hour of work actually costs

Wages are only part of the real cost of an employee. Superannuation, leave loading, payroll tax where it applies, workers compensation premiums, and public holiday loading all sit on top. If you are quoting jobs, setting prices, or approving overtime without knowing the fully loaded cost per hour, you are guessing at your own margins.

This matters most at the moments you can least afford to get it wrong: quoting a fixed-price job, deciding whether to approve overtime instead of hiring, or working out whether a new hire is genuinely affordable. Businesses that only track the base wage tend to under-quote, and by the time the true cost shows up on the profit and loss statement, the job is already finished and the price is locked in.

A useful habit is to recalculate this figure whenever the superannuation guarantee rate changes, a payroll tax threshold moves, or your workers compensation premium is renewed. Treat it as a live number, not a one-off exercise, and review it alongside your wages the same way you would review any other input cost in the business.

6. Payroll takes more time than it should

If processing pay takes more than a few hours a fortnight for a small team, or eats a full day of someone’s week in a larger one, that is a direct cost even before you count errors. It is also a sign the process relies on manual steps that a proper system, or a specialist provider, would remove. Ask yourself honestly: is that person’s time better spent running payroll, or running the parts of the business only they can do? VeiraMal’s payroll services exist precisely to take that manual load off small business owners, and we have covered why in more detail in Why Small Business Payroll Services Exist.

7. Payroll has never been reviewed by anyone outside the business

If the same person who set up your payroll process is the only one who has ever checked it, you have no independent test of whether it is actually correct. Award interpretation is genuinely difficult, and the person doing your payroll is rarely the person best placed to audit it. An outside review, even a short one, usually finds something. Whether that something is a small rounding issue or a systemic underpayment risk is the difference between a quick fix and a very expensive one.

An independent review also protects the person who has been running payroll. If an error is eventually found by Fair Work or the ATO instead of by your own process, it looks like negligence rather than an honest mistake, and it is far more expensive to fix retrospectively than to catch early. Treat a payroll review the same way you would treat an accounting audit: routine, not a sign that something is already wrong.

What one payroll error actually costs, once you add it all up

It helps to put a number on this rather than treat it as an abstract risk. A single underpayment rarely stays a single underpayment. Once it is found, whether by an employee, a union, or a Fair Work inspector, the standard process is to check every employee who could have been affected by the same rate, back to when the error started. A mistake that has been running quietly for eighteen months across a roster of ten award-covered staff is not a small correction. It is back pay for ten people, superannuation guarantee shortfall on top of that back pay, and often the administrative cost of preparing the calculations yourself or paying someone to do it for you.

Then there is the cost that never shows up on a balance sheet. Employees talk to each other about pay. A visible payroll mistake, even a genuinely honest one, dents trust in the business faster than almost anything else a small employer can get wrong. Recruiting to replace someone who left over a pay dispute costs more than the correction itself would have.

None of this requires bad intent. Every statistic in this article, from the ATO’s superannuation guarantee gap to the Fair Work Ombudsman’s wage recoveries, comes from ordinary businesses using a payroll process that quietly drifted out of compliance rather than one that set out to underpay anyone. That is exactly why the seven signs above are worth checking against your own business now, while the fix is still simple.

The businesses that get this right treat payroll as a compliance function with a cost attached, not an administrative task to hand to whoever has the most spare time. That shift in thinking, more than any specific software or system, is usually what separates a payroll process that quietly costs money from one that quietly protects it.
