Employment Hero vs MicrOpay – how they compare for AU/NZ payroll

How Employment Hero and MicrOpay differ

Employment Hero is an Australian-founded (2014) ‘Employment Operating System’ spanning HR, payroll, benefits, recruitment and workforce management, reportedly used by 300,000+ businesses across AU, NZ, the UK, Canada, Singapore and Malaysia. Its payroll engine originated as KeyPay (acquired 2022), and it holds ISO 27001/27017/27018 certification and SOC 2 Type II compliance.

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.

The core distinction for a buyer is what each platform was built to optimise for: Employment Hero is a broad SME “Employment OS” spanning HR, payroll, benefits and hiring, while MicrOpay is an established Australian payroll application, owned by The Access Group, that runs on-premise or hosted by Access. 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 Employment Hero fits

Employment Hero is built for small-to-medium AU/NZ businesses that want HR, payroll, benefits and hiring bundled into one broad, self-service platform with AI-assisted tooling (Hero AI). Its benefits marketplace, recruitment and onboarding modules, and multi-country reach make it a strong fit for SMEs that value breadth and self-service over dedicated, high-touch AU/NZ enterprise payroll support.

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 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 Employment Hero or MicrOpay. Some organisations run Employment Hero or MicrOpay 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.
