How Ace Payroll and ReadyTech 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.
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: Ace Payroll is a low-cost desktop payroll tool for small NZ businesses, now being decommissioned, 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.
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.
