The short version

MicrOpay is an established Australian payroll application from The Access Group; ReadyTech is an ASX-listed group whose workforce suite was built through acquisitions. The main differences are one payroll engine against several, and ReadyTech's rostering focus for shift-based industries.

How MicrOpay and ReadyTech differ

MicrOpay (now branded Access MicrOpay Evo) is a long-standing Australian payroll application owned by The Access Group, which acquired it as part of Sage's Australian and Asian businesses in 2021. It runs as Windows software on the customer's own servers or hosted by Access (Access Payroll Online), and has shipped STP Phase 2 and Payday Super updates, an integrated super clearing house, and an Evo layer adding dashboards, analytics and an AI Copilot.

ReadyTech is an ASX-listed (ASX:RDY) technology group operating across three divisions – Workforce Solutions, Education & Work Pathways, and Government & Justice. Its Ready Workforce payroll offering (Ready Pay) was built through acquisitions including HR3, Aussiepay and Zambion (NZ), and it launched Orqestra AI in February 2026.

The core distinction for a buyer is what each platform was built to optimise for: MicrOpay is an established Australian payroll application, owned by The Access Group, that runs on-premise or hosted by Access, while ReadyTech is an ASX-listed workforce technology group spanning payroll, education and government divisions. 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.

Where MicrOpay fits

MicrOpay is built for Australian organisations – typically small to mid-sized, running payroll in-house – that want a familiar, long-established payroll engine with the option of on-premise or Access-hosted delivery. Its large installed base, Payday Super-ready releases with built-in super clearing, and the newer Evo analytics and Copilot layer make it a strong fit where continuity with a known AU payroll application matters more than deep NZ coverage or enterprise award complexity.

Where ReadyTech fits

ReadyTech is built for shift-based and rostering-intensive AU/NZ organisations that want strong workforce management alongside payroll, backed by an ASX-listed group with HR breadth. Its Ready Pay engines (via HR3, Aussiepay and Zambion for NZ) and Orqestra AI make it a strong fit where rostering and time-and-attendance depth matter – buyers should confirm which underlying engine applies and the consolidation roadmap.

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 MicrOpay or ReadyTech. Some organisations run MicrOpay or ReadyTech 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 MicrOpay or ReadyTech better for Australian payroll?

MicrOpay is an established Australian payroll application, owned by The Access Group, that runs on-premise or hosted by Access. ReadyTech is an ASX-listed workforce technology group spanning payroll, education and government divisions. 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 MicrOpay and ReadyTech handle New Zealand payroll?

MicrOpay: NZ payday filing & KiwiSaver documented; Holidays Act depth not verified. ReadyTech: NZ via Zambion acquisition (integration 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.

How does Affinity compare to MicrOpay and ReadyTech?

Affinity is an AU/NZ enterprise payroll specialist. It does not try to match MicrOpay or ReadyTech 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.
