How Ace Payroll and Preceda 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.
Preceda is a 30+ year-old Australian-developed payroll and time platform historically used by mid-market and enterprise organisations, now owned by Dayforce (formerly Ceridian, via its 2021 Ascender acquisition) – itself taken private by Thoma Bravo in February 2026. Dayforce set Preceda's formal end-of-life for 2026, with remaining customer migrations to the Dayforce platform continuing into 2027.
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 Preceda is an enterprise AU/NZ payroll and time platform now being retired in favour of Dayforce. 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.
