The reality? Payroll has become a department of its own due to its demanding nature. That’s why more businesses are turning to outsourced payroll services, with 51.6% of them reporting they are satisfied or very satisfied with their provider.
What is payroll outsourcing?
Payroll outsourcing is when a business partners with an external provider to manage its payroll functions. This can include calculating wages, managing tax and superannuation, generating payslips, processing payments, and ensuring compliance with Fair Work and ATO requirements. Rather than handling these tasks in-house, businesses hand them off to a specialist with the systems and expertise to do it accurately and efficiently.
At its core, payroll outsourcing involves shifting payroll from an internal function to an externally managed service. The provider takes responsibility for delivering the end-to-end payroll process, using dedicated technology, automation, and compliance knowledge on behalf of the business.
Brief overview of the payroll process
Payroll processing follows a structured cycle that repeats each pay period, which ensures employees are paid accurately and on time. It typically includes tracking hours worked, calculating wages and entitlements, applying tax and superannuation, distributing payments, and submitting reports to the ATO. While the process is routine, each step requires precision, system coordination, and up-to-date compliance.
🤔 Why businesses outsource payroll
Every business reaches a point where managing payroll internally becomes more of a burden than a benefit. Whether it's the mounting complexity of compliance, the time drain on valuable resources, or the risk of costly errors, organisations across Australia are recognising that specialist expertise often delivers better results.
Three key drivers push businesses toward outsourcing:
• Complexity overload – Modern Awards, EBAs, and constant legislative changes
• Resource drain – Internal teams spending days on payroll instead of strategic work
• Compliance risk – Penalties for errors can reach thousands per breach
📈 Current state of payroll outsourcing industry
The Australian payroll outsourcing market continues to expand, here’s a look at what’s happening in the industry:
• 40.2% of small businesses now outsource payroll operations
• 41.4% of medium businesses use external payroll providers
• All employers are now required to comply with STP Phase 2 expanded reporting
• Criminal penalties from 2025 for intentional underpayment - up to 10 years imprisonment
👉 Who should consider using this guide
• Small business owners facing payroll complexity with limited resources
• HR managers seeking operational efficiency improvements
• CFOs evaluating cost-effective payroll solutions
• Operations managers handling workforce expansion
• Payroll managers assessing service alternatives
🏢 Business size considerations
This guide provides value regardless of organisation size, here’s how:
• Small businesses (under 20 employees) – Establishing compliant payroll processes from the beginning
• Medium businesses (20-199 employees) – Managing increased complexity and multi-state operations
• Large businesses (200+ employees) – Optimising costs and improving efficiency
If payroll processing consumes excessive time, causes compliance concerns, or limits your ability to scale, this guide will help you evaluate whether outsourcing aligns with your business needs.
Understanding payroll: The foundation
Modern payroll encompasses far more than simply paying employees. It includes managing award rates, penalty loadings, leave accruals, and ensuring compliance with Enterprise Bargaining Agreements (EBAs).
• Salary and wage calculations – Base pay, overtime, shift penalties, and allowances according to Modern Awards and EBAs.
• Tax withholdings and deductions – PAYG withholding, HELP repayments, child support, and salary sacrifice arrangements.
• Benefits administration – Leave entitlements, superannuation contributions, and salary packaging options.
• Time and attendance tracking – Recording hours worked, managing rosters, and calculating time-based entitlements.
• Compliance and reporting requirements – Single Touch Payroll submissions, payment summaries, and Fair Work documentation.
👎Common payroll challenges
Modern payroll management involves navigating multiple challenges that can overwhelm internal teams, such as:
• Complexity of tax regulations – Managing PAYG, state payroll taxes, FBT, and super across multiple jurisdictions requires constant attention to detail.
• Compliance risks and penalties – Fair Work and ATO penalties can reach tens of thousands per breach, with underpayment claims potentially spanning years.
• Time-consuming administrative tasks – Weekly payroll processing, timesheet reconciliation, and employee queries consume hours that could focus on core business.
• Technology and system requirements – Keeping software updated for legislative changes and maintaining Single Touch Payroll compliance demands ongoing investment.
Outsourced vs In-House Payroll: Making the right choice
The big question: to keep managing payroll internally or outsource specialists? Both paths have clear advantages, but the right choice depends on respective business needs and circumstances.
In-house payroll management
In-house payroll means handling everything internally – from calculating wages to submitting tax reports. The company employs payroll staff, maintains software, and takes full responsibility for compliance. It's essentially running a complete payroll department within the organisation.
✅ Pros:
• Control – Direct oversight of all payroll processes and immediate data access
• Customisation – Tailor processes exactly to business needs
• Data security – Sensitive information stays within the organisation
❌ Cons:
• Resource intensive – Requires dedicated staff with specialised payroll knowledge
• Compliance risks – Teams must keep up with constant legislative changes
• Technology costs – Software licenses, updates, and IT infrastructure add up
• Infrastructure needs – Backup systems, training, and ongoing development required
Outsourced payroll management
Outsourcing means hiring an external company to handle payroll. The business provides employee hours and information. Access Payroll Outsourcing can manage all or part of your payroll process, from calculations, tax obligations, superannuation, and compliance – bringing economies of scale and specialised expertise.
✅ Pros:
• Expertise – Access to payroll specialists who live and breathe compliance
• Cost savings – No need for in-house payroll staff or expensive software
• Compliance assurance – Provider takes responsibility for staying current
• Scalability – Easily handle growth or seasonal workforce changes
❌ Cons:
• Less control – Working to external timelines and processes
• Provider dependency – Service quality varies between providers
• Communication gaps – Less direct contact with payroll processing

Decision framework: In-house or outsourced?
Choosing between in-house payroll and outsourcing isn’t one-size-fits-all. The right approach depends on how your business operates today and where it’s heading.
💼 Business size considerations
-
For small businesses
Outsourcing is often the most cost-effective option, especially when internal payroll resources are limited and compliance requirements are still unfamiliar. -
For mid-sized businesses
A hybrid approach works well — maintaining control over strategy while offloading admin-heavy tasks to a specialist provider. -
For larger organisations
Combining internal teams with outsourced support can help manage complexity, scale, and compliance across multiple entities or locations.
🏢 Industry-specific factors
-
Retail, hospitality, construction, and healthcare
Complex awards, shift-based rosters, and seasonal work make these industries strong candidates for outsourcing or SaaS platforms with built-in compliance tools. -
Professional services and tech
In these sectors, payroll structures are often simpler, which makes in-house management a viable option — particularly when supported by flexible and modern software.
🚀 Growth stage implications
-
Scaling businesses
Outsourcing provides consistency, automation, and compliance support as headcount grows and complexity increases. -
Established organisations
Switching to a managed payroll service can reduce costs, streamline operations, and free up internal resources for more strategic priorities.

Benefits of payroll outsourcing
The benefits of payroll outsourcing extend well beyond simple time savings. Here's what businesses typically gain from making the switch.
💰 Cost savings
Payroll outsourcing is no longer limited to large corporates. In fact, according to the 2024 Australian Payroll Survey, 40.2% of Australian employers with fewer than 100 employees now outsource payroll — a sign that even small to mid-sized businesses are prioritising accuracy, compliance, and cost control.
By outsourcing, businesses eliminate multiple hidden costs:
✓ Reduced labour costs
✓ Lower technology investments
✓ Economies of scale
✓ Predictable pricing models
✅ Compliance and risk management
Providers assume responsibility for staying current with Australian employment law and bear liability for compliance errors. 35% of businesses report being satisfied with their current payroll technology, this highlights the value of outsourcing to providers with up-to-date systems and compliance tools.
✓ Expert knowledge of regulations
✓ Reduced penalty risks
✓ Automatic updates for law changes
✓ Audit protection services
⏰ Time and resource efficiency
Teams reclaim hours usually lost on payroll processing and compliance to focus on activities that drive business growth. The time savings translate into:
✓ Streamlined processes – Simplified workflows and reduced manual tasks
✓ Focus on core business activities – More time for strategic initiatives
✓ Reduced administrative burden – Less paperwork and routine processing
🚀 Technology and innovation
Outsourcing providers continuously invest in the latest payroll technology, security updates, and compliance features that would be costly for individual businesses to maintain. Through outsourcing, businesses gain access to:
✓ Advanced systems – Enterprise-level technology without the price tag
✓ Regular software updates – Automatic upgrades for new features and compliance
✓ Integration capabilities – Seamless connections with your existing HR and accounting systems
✓ Mobile accessibility – Manage approvals and access reports from anywhere
📈 Scalability and flexibility
Business growth shouldn't be limited by payroll capacity. Whether you're hiring seasonal workers, expanding interstate, or experiencing rapid growth, outsourced providers scale with your business’ needs without requiring system overhauls or additional staff.
✓ Easy scaling for growth – Add employees without infrastructure changes
✓ Seasonal workforce management – Handle peak periods without permanent overhead
✓ Geographic expansion support – Multi-state compliance without local expertise
Potential drawbacks and considerations
While outsourcing delivers substantial benefits, understanding potential challenges ensures you make an informed decision and select the right provider.
🔒 Reduced control
When you outsource payroll, you're entrusting a critical business function to an external provider. This shift means working within their systems and timelines rather than having immediate access to make changes.
- Reduced oversight of processes – Lack of direct visibility into day-to-day operations
- Dependency on external provider – Must follow their schedules and procedures
- Limited customisation options – Unique pay arrangements may not fit standard models
🛡️ Data security concerns
Employee payroll data includes some of your most sensitive information. When outsourcing, this data resides in external systems beyond your direct control.
- Sensitive information sharing – Tax file numbers, bank details, and salaries in third-party hands
- Cybersecurity considerations – Despite strong security measures, external storage introduces risk
- Data breach risks and liability – Understanding who bears responsibility if breaches occur
💬 Communication challenges
Adding an intermediary between your HR team and payroll processing can create gaps in communication and responsiveness.
- Potential for miscommunication – Instructions may be misinterpreted without direct oversight
- Response time variations – Queries might not receive immediate answers during peak periods
- Less direct employee interaction – Employees cannot simply walk to payroll with questions
💸 Hidden costs
The advertised per-payslip price rarely tells the full story. Additional charges can significantly impact your total investment.
- Setup and implementation fees – Initial configuration can cost thousands
- Additional service charges – Year-end processing, custom reports, award interpretations
- Contract termination costs – Exit fees and data extraction charges
⚡ Vendor dependency risk
Relying on an external provider introduces business continuity considerations that need careful evaluation.
- Provider stability concerns – What happens if they experience financial difficulties?
- Switching costs and complexity – Changing providers requires significant time and resources
Payroll outsourcing costs: Understanding your investment
💳 Pricing models
Payroll providers typically offer several pricing structures. The most common is per-employee-per-month (PEPM) pricing, though some providers offer percentage-based or flat-rate models for specific business sizes. Here are the main pricing structures you'll encounter:
-
Per-employee pricing (PEPM)
-
Base fee plus per-employee charges
-
Percentage of payroll models
-
Flat-rate pricing options
📊 Cost factors
Your final cost depends on multiple variables beyond employee headcount. Payroll frequency significantly impacts pricing - weekly payrolls require more processing than monthly ones. Geographic spread matters too, as multi-state operations involve different tax jurisdictions. Key factors that influence your investment include:
-
Number of employees
-
Payroll frequency
-
Service level complexity
-
Geographic coverage
-
Integration requirements
📈 Cost comparison framework
To accurately evaluate outsourcing costs, you need to compare your total current expenses against provider quotes. This means calculating not just visible costs like salaries but also hidden expenses like compliance risks and opportunity costs. Use this framework for your analysis:
-
In-house vs outsourced cost analysis
-
Total cost of ownership calculations

💰 Hidden and additional costs
Beyond base pricing, various charges can significantly impact your total investment. These often aren't mentioned in initial quotes but can add substantial costs over time. Watch for these common additional charges:
-
Implementation and setup fees
-
Year-end processing charges
-
Custom reporting fees
-
Integration and API costs
-
Termination and switching costs

Key areas to consider:
✓ Current payroll requirements analysis
✓ Future growth projections

✓ Data ownership and portability
✓ Termination clauses and procedures
✓ Liability and indemnification
Implementation and transition process

✓ Continuous improvement processes
Industry-specific considerations
Different businesses face unique payroll challenges based on their size, complexity, and industry. Understanding these specific requirements helps you choose a provider with the right expertise and ensures they can handle your particular needs effectively.

🏢 Enterprise-level requirements
Large organisations need providers capable of handling complexity on a scale. Multi-entity structures, various awards, and interstate operations require sophisticated solutions. Essential capabilities:
✓ Complex organisational structures – Multiple entities, divisions, and cost centres
✓ Multi-location considerations – Different state taxes and regional requirements
✓ Advanced reporting needs – Custom dashboards and board-ready reports
🔧 Industry-specific needs
Certain industries have unique payroll complexities that standard providers may struggle to handle. Ensure your chosen provider has experience in your sector. Industries requiring specialised expertise include:

✓ Seasonal businesses – Rapid changes in schedules, temporary workers
✓ Union environments – EBA compliance and collective agreements
✓ Government contractors – Security clearances and compliance reporting
