Payroll Services vs. In-House Payroll: A Practical Cost Comparison for Small Businesses

July 16, 2026

Choosing between outsourced payroll services and managing payroll in-house is a decision that directly affects how much time and money a small business spends each pay cycle. For businesses with 5 to 20 employees, the true cost of each option is rarely obvious until it is broken down honestly. This article compares both approaches so Melbourne small business owners can make a more informed choice.

The Real Time Cost of Running Payroll In-House


In-house payroll takes more time than most owners expect. For a team of 5 to 20 employees, a single pay run may involve collecting and verifying timesheets, calculating gross and net pay, applying the correct award rates, generating payslips, lodging Single Touch Payroll (STP) reports with the ATO, and processing superannuation contributions. When you add it up across a fortnightly cycle, this process can reasonably consume two to five hours of an owner's or administrator's time.


That time has a dollar value. If the person handling payroll earns or is worth $45 to $70 per hour, a business may be spending $90 to $350 per pay run on labour alone, before accounting for software subscriptions, training time, or the occasional costly error. 

The hidden problem is that this cost tends to be invisible. It sits inside an existing salary or the owner's unpaid hours rather than appearing as a line item on the profit and loss statement. 


What Does Outsourced Payroll Processing in Melbourne Typically Cost?


Professional payroll services are generally priced on a per-employee, per-pay-run basis. For small Melbourne, VIC, businesses, this may range from a modest flat fee for a handful of staff to a scaled fee as headcount grows. Managed payroll processing typically includes timesheet processing, payslip generation, STP lodgement, superannuation reporting, and ongoing compliance updates as award rates or tax thresholds change.


This is a key distinction from a DIY software subscription. Payroll software can cost as little as $10 to $30 per month, but it does not process payroll for you. The compliance responsibility, award interpretation, and ATO lodgement still sit with the business owner.


The break-even point for many Melbourne small businesses tends to fall around the 5 to 8 employee mark. At that size, the combined cost of software, processing time, and compliance risk may begin to match or exceed what a professional service would charge. 


The Compliance Costs That Catch Businesses Off Guard


Compliance penalties are the expense that the in-house model often does not account for until it is too late. Late or incorrect STP reporting, underpaid superannuation, or incorrect award classification can each trigger ATO penalties or Fair Work investigations. These costs can far outweigh the savings made by keeping payroll in-house. A professional payroll service may reduce this risk by keeping your obligations current and accurate at every pay run.
