Ace Payroll vs Definitiv – how they compare for AU/NZ payroll

For: Payroll Managers, HR Leaders, Finance Directors|11 min read|Last updated: August 2026

This comparison is published by Affinity. Vendor information is based on publicly available sources. Contact each provider directly for their current capabilities.

Summary

Ace Payroll is a low-cost desktop payroll tool for small NZ businesses, now being decommissioned. Definitiv is a cloud-native AU/NZ/Singapore payroll and workforce-management platform. Affinity is shown here as a separate column: an AU/NZ enterprise payroll specialist for organisations whose complexity is concentrated in Australia and New Zealand.

How Ace Payroll and Definitiv differ

Ace Payroll is a New Zealand-only, locally-installed desktop payroll application, owned by MYOB since 2015 and originally built in 1990 for small NZ employers. It handles IRD Payday Filing, KiwiSaver and ACC levies natively, priced on a flat-fee rather than per-employee basis. MYOB has confirmed Ace Payroll will be decommissioned on 1 April 2027, with customers directed to MYOB Business Payroll.

Definitiv (marketed as Definitiv Evo) is a cloud-native AU/NZ/Singapore payroll and workforce-management platform originally built in Perth, acquired by The Access Group (a UK-headquartered global software group) in 2021. It offers a 100% configurable Award Engine, purpose-built rostering with live time-tracking, and Evo Copilot AI insights.

The core distinction for a buyer is what each platform was built to optimise for: Ace Payroll is a low-cost desktop payroll tool for small NZ businesses, now being decommissioned, while Definitiv is a cloud-native AU/NZ/Singapore payroll and workforce-management platform. AU/NZ payroll sits within each vendor's broader focus rather than as the sole product, which is where a specialist platform like Affinity differs from both.

One further point matters for this comparison: Ace Payroll is being retired by its owner (see the FAQ below), which means organisations still on it face a mandatory migration rather than a discretionary choice.

Where Ace Payroll fits

Ace Payroll has historically suited very small NZ employers wanting a low-cost, simple desktop tool for IRD compliance rather than a full-featured platform. With MYOB decommissioning it on 1 April 2027, it is no longer a viable long-term choice – the practical question for remaining Ace Payroll customers is which platform to move to, not whether to move.

Where Definitiv fits

Definitiv is built for mid-to-large AU/NZ organisations with complex, multi-award structures that want a cloud-native platform combining a configurable Award Engine with integrated rostering and live time-tracking. Backed by The Access Group's scale, it is a strong fit for organisations that want award complexity and workforce management handled natively in one product.

Where Affinity fits

For organisations whose payroll complexity is concentrated in Australia and New Zealand, a specialist engine with pre-payslip intelligence, delivery-model flexibility, local data residency, and named local support is a different proposition to either Ace Payroll or Definitiv. Some organisations run Ace Payroll or Definitiv for their broader positioning and Affinity for a complex AU/NZ operation; others choose Affinity specifically because they need genuine cross-Tasman depth that neither platform is built to prioritise.

Frequently asked questions

Is Ace Payroll or Definitiv better for Australian payroll?

Ace Payroll is a low-cost desktop payroll tool for small NZ businesses, now being decommissioned. Definitiv is a cloud-native AU/NZ/Singapore payroll and workforce-management platform. Which fits better for Australian payroll depends on which of those is closer to what your organisation actually needs. Confirm current AU award and EBA depth directly with both providers. For organisations whose complexity is concentrated in Australia and New Zealand, a specialist engine like Affinity is built specifically for that depth.

Do Ace Payroll and Definitiv handle New Zealand payroll?

Ace Payroll: Native IRD Payday Filing, KiwiSaver and ACC levies. Definitiv: NZ payroll supported (also Singapore); Holidays Act depth to confirm. Confirm current NZ depth directly with each provider – Holidays Act, KiwiSaver and IRD payday filing all require genuine local engine work, not just tax-table updates. Affinity runs a purpose-built NZ payroll engine with 40+ years of Holidays Act experience and an NZ-based support team.

What is the main difference between Ace Payroll and Definitiv?

Ace Payroll is a low-cost desktop payroll tool for small NZ businesses, now being decommissioned, while Definitiv is a cloud-native AU/NZ/Singapore payroll and workforce-management platform. They overlap on core payroll compliance but differ in scope, ownership model, and the customer base each was built to serve.

How does Affinity compare to Ace Payroll and Definitiv?

Affinity is an AU/NZ enterprise payroll specialist. It does not try to match Ace Payroll or Definitiv on their own ground; it competes on depth of AU/NZ award and Holidays Act compliance, pre-payslip intelligence, delivery-model flexibility, local data residency, and named local support.

Why is Ace Payroll being retired, and what should I do?

Ace Payroll is a New Zealand-only, locally-installed desktop payroll application, owned by MYOB since 2015 and originally built in 1990 for small NZ employers. It handles IRD Payday Filing, KiwiSaver and ACC levies natively, priced on a flat-fee rather than per-employee basis. MYOB has confirmed Ace Payroll will be decommissioned on 1 April 2027, with customers directed to MYOB Business Payroll. If your organisation is still running Ace Payroll, treat this as a forced re-platforming project on a deadline, not a routine software update. It is a reasonable moment to evaluate options on their merits – including a specialist AU/NZ payroll platform like Affinity – rather than defaulting to whatever migration path is offered.
