How Much Does Payroll Outsourcing Cost for a Small Business?

How much does it cost to outsource payroll? There isn’t one standard price. Payroll providers may charge per employee per pay run, use a flat monthly fee or offer different service tiers. The amount a small business pays depends on employee numbers, pay frequency, awards, variable hours and what’s included in the service.

The true cost of payroll also includes more than a software subscription or provider fee. It includes the time spent preparing and checking each pay run and correcting mistakes. Comparing these costs together gives you a more useful picture of whether outsourcing payroll makes financial sense for your business.

How much does it cost to outsource payroll?

In practice, the cost may be calculated per employee per pay run, as a flat monthly fee or as part of a service package, with the final amount depending on the complexity of your payroll.

Every “payroll costs $X per employee” figure circulating online describes one specific arrangement, not a universal rate. Two businesses with the same headcount can have very different payroll workloads — one might run five employees on a single retail award with stable hours, the other five employees split across two awards with a mix of casual and part-time staff and rosters that change weekly. Both have “five employees.” Neither has the same amount of work behind each pay run, so neither should expect the same quote.

How payroll costs differ by business type

These examples show why employee numbers alone are not enough to produce a meaningful quote. They illustrate how the workload can differ; they are not price estimates.

On paper, two businesses may have the same headcount. One payroll can still take much longer if every pay run involves changing hours, allowances or penalty-rate checks.

The three ways small businesses run payroll

A common path is to start with software or an in-house process, then outsource when the workload becomes uncomfortable to manage. There’s no universally correct point to switch. It depends on how much time the business has available and how much payroll risk the owner is willing to manage. This article focuses mainly on outsourced pricing, with the first two approaches as the baseline for comparison.

What “payroll outsourcing” actually covers

The scope varies considerably between providers. Depending on the engagement, outsourced payroll may include pay-run processing, Single Touch Payroll reporting, super processing, record maintenance and support with payroll queries. Award interpretation, employee enquiries, ATO contact and historical reviews may be separate services. Get the inclusions in writing before comparing prices.

What affects the cost of outsourcing payroll?

Providers commonly use employee headcount as a pricing baseline because it’s easy to measure. Headcount doesn’t show how much work sits behind each pay run. A business operating under one well-understood modern award is usually simpler to process. Several awards can mean different pay rates, allowances and penalty rules to check.

One situation we see fairly often is a business that starts with employees under one award, then expands into a new type of work without reviewing whether another award applies. A Melbourne café might begin retail or catering work, for example. Reviewing and correcting that setup takes additional time, which may affect the quote.

A common surprise: moving from one award to two can change a payroll quote more than hiring one extra employee under an award that’s already configured.

A full-time workforce on fixed hours is more predictable to process than a mix of full-time, part-time and casual staff. Variable hours need to be checked against rosters or timesheets each pay run.

Pay frequency compounds the difference. Weekly payroll creates roughly four processing events a month, compared with two for fortnightly or one for monthly. Per-pay-run pricing reflects that directly. A flat monthly quote usually assumes a particular cycle, so confirm which one the provider has allowed for.

How much do payroll services charge?

No pricing model is always cheaper. The right one depends on how stable the payroll is and whether you prefer event-based billing or one predictable monthly figure.

How to outsource payroll and get an accurate quote

The quote process usually covers four steps:

1. Map the payroll: confirm headcount, employment types, pay cycles, awards, locations and current software.
2. Define the service: decide whether the provider will process pay runs only or also handle STP, super, onboarding, terminations and employee queries.
3. Review the starting position: check whether existing records, classifications and STP year-to-date figures are ready to transfer or need correction first.
4. Separate ongoing and one-off work: quote the recurring service apart from setup, migration or historical cleanup.

A quote prepared from headcount alone can miss the work that matters most. For a casual-heavy Melbourne hospitality or retail payroll, a recent roster and sample pay run will often reveal more than an employee list.

What may be included in the fee

Two quotes can look similar while covering very different services. Check each of these items before comparing the totals:

• STP reporting and super processing
• New-employee onboarding and termination calculations
• Payroll software and any separate subscription
• Award interpretation and classification checks
• Employee payroll enquiries and ATO contact
• Historical reviews or corrections

For Victorian businesses, also confirm whether any payroll tax support is included. Processing wages and managing Victorian payroll tax are separate responsibilities, and a payroll service may cover one without the other.

Compare scope before price: a cheaper quote can become the more expensive option once new starters, terminations, super processing and award reviews are added separately.

How do I compare quotes from different payroll service providers?

Use the same annual-cost calculation for every provider:

Estimated annual payroll cost = recurring fees + software fees + setup costs + separately billed payroll events + internal review time

Work through the quote in this order:

1. Convert weekly, per-pay-run or monthly charges into an annual recurring total.
2. Add software subscriptions and one-off setup or migration fees.
3. Estimate the likely number of separately billed events, such as new starters and terminations.
4. Include the internal time still needed to approve payroll, provide timesheets and answer exceptions.
5. Record anything the provider has excluded, because that work may still need to be paid for or handled internally.

This gives you a like-for-like comparison without relying on a market average that may have little in common with your payroll.

Setup and transition costs

Moving payroll to a new provider often involves a one-off setup fee. This covers transferring award and classification settings, importing employee records and handing over STP year-to-date figures without duplicating or dropping reported amounts.

A new provider will usually review recent pay runs during the transition. Historical errors often surface at this point, and correcting them can add to the initial cost. That isn’t strictly a switching fee; it is a pre-existing issue discovered during the handover. A first employee also needs setup time, even when there is no old system to transfer.

How Payday Super has affected pricing

From 1 July 2026, Payday Super requires super guarantee contributions to be paid each payday instead of quarterly. The payment generally needs to reach the employee’s super fund within 7 business days after payday, with 20 business days allowed for a new employee’s first contribution.

Super is now checked every pay cycle, regardless of whether payroll is self-managed, handled in-house or outsourced. Some providers have adjusted their pricing for the extra frequency of the work. Ask whether a quote already reflects the new deadline.

The cost of a payroll error, whichever way you run it

A wrong pay rate or classification rarely stays a one-off mistake. It repeats until someone catches it. When an underpayment is discovered, the employee generally needs to be back paid in full.

Correcting the problem creates additional work and cost, whether payroll was handled internally or by a provider. A higher fee that includes active compliance checking can therefore cost less overall than a cheaper service that allows errors to compound. Our guide to reducing payroll errors covers the checks worth running each pay cycle.

Outsourced vs in-house: the broader decision

Pricing is only one part of the decision. Time, compliance risk and continuity when the usual payroll person is unavailable also matter. Our guide to choosing between internal and outsourced payroll covers that broader comparison. The payroll provider vs payroll software guide explains what a provider adds on top of software.

What to consider when outsourcing payroll

Cost matters when outsourcing payroll, but it shouldn’t be the only consideration. Look at how much work sits behind each pay run, which responsibilities the provider will take on and what your business will still need to manage internally.

For a small business, consider:

• The recurring payroll service fee and any software costs
• How employee numbers and pay frequency affect the price
• Whether STP reporting, super processing and payroll queries are included
• How the provider handles awards, classifications and variable hours
• Setup, migration, new-starter and termination fees
• How much internal approval and checking your team will still need to do
• What happens when your employee numbers or payroll complexity increase

The cheapest payroll service isn’t necessarily the lowest-cost option overall. Compare providers using the same scope and include the internal time your business will still spend preparing, approving and reviewing payroll.

Questions to ask before choosing a provider

• Does this fee include STP lodgement and superannuation processing, or are they billed separately?
• Is the quote based on my actual pay cycle frequency, or an assumed one?
• What happens with a new starter or termination mid-cycle — is that included or a separate charge?
• Is there a one-off setup fee, and does it change if historical errors are found during onboarding?
• Which software platform is assumed, and is there a separate subscription cost on top?
• Who is responsible for checking awards and classifications after the payroll is set up?
