Affinity vs Employment Hero – outsourced & managed payroll compared

Delivery footprint

Both providers run on cloud-native, multi-tenant SaaS architecture. The difference is where the people running your payroll actually sit.

Calculation depth

Employment Hero's award engine ships as a pre-built modern awards library with automated rule updating, which covers standard awards and standard EBAs well and keeps pace with routine changes without manual intervention. The trade-off is that this pre-built approach can hit configuration limits when an agreement is genuinely bespoke – a heavily negotiated multi-tier EBA with unusual allowance stacking or shift penalty structures. Its NZ side runs an automated Holidays Act compliance engine with continuous rate checks, which is a solid standard implementation.

Affinity's rule builder was designed the other way around: it is built for the intricate cases first – complex shift penalties, multi-tier EBAs, and layered allowances – rather than a standard library with edge-case limits. On the NZ side, Affinity's native engine tracks continuous gross earnings, ordinary weekly pay (OWP), average daily pay (ADP), and leave liabilities directly, rather than applying a checks layer on top of a general engine.

Both providers handle statutory lodgements automatically – Employment Hero submits STP Phase 2 directly to the ATO with Beam superannuation clearing house integration and IRD filing, while Affinity lodges STP Phase 2, is Pay Day Super ready, and handles PAYG/SuperStream and NZ IRD Payday Filing directly. For organisations whose award environment is mostly standard, the practical difference here may be small. For organisations with bespoke, heavily negotiated EBAs, it is worth testing both engines against your actual pay conditions before deciding.

Audit, QA & who owns support

This is the area that most differentiates outsourced payroll providers, because it determines whose team fields the phone call when an employee thinks their pay is wrong.

Employment Hero's QA layer is its AI Payroll Agent, which runs anomaly detection – identifying overtime spikes, zero-hour records, and leave discrepancies – as an automated check before issues reach a payslip. But for Tier-1 support, the model is client-retained: employees are directed to the Swag app or your internal HR desk, and Employment Hero's managed payroll specialists interface only with your client admins during implementation and then via the managed payroll operations desk – not with your staff directly. In practice, if an employee has a question about their payslip, your HR team is the first (and often only) point of contact.

Affinity runs pre-payslip automated checking through Payroll IQ, combined with dedicated local payroll manager variance audits – a human review layer on top of the automated one. For support, Affinity's model is direct provider ownership: the local AU/NZ team handles Tier-1 employee queries itself, with a named local Payroll Manager as the primary operational escalation point. The employee's question goes to Affinity, not to your HR desk.

Banking & who carries the liability

Employment Hero automates payments through Swag/NPP infrastructure, or alternatively generates ABA bank download files for the client to execute through their own banking portal – giving the client a choice between automated disbursal and a client-executed file-based model.

Affinity operates a provider-managed trust and disbursal model: Affinity executes net pay, ATO, IRD and super fund payments directly, or via ABA files where preferred, so the client is not required to run the disbursal step themselves.

Regardless of which banking or disbursal model is in place, statutory payroll compliance liability is non-delegable under the Fair Work Act 2009 (AU) and equivalent NZ employment law. Whether a provider executes payments directly or hands the client an ABA file to run, the employer remains legally accountable for correct and timely payment of wages, tax, and superannuation – outsourcing the mechanics does not outsource the liability.

Retained resourcing & implementation

How much of your own team's time this arrangement still requires, and how long it takes to get live.

Where Employment Hero excels

Employment Hero is genuinely strong in areas that matter for small-to-mid businesses wanting speed and an all-in-one system.

Where Affinity excels

Affinity's advantages centre on onshore delivery, direct employee support, and depth for complex agreements.

Who's each provider best for?

The right fit depends on scale, agreement complexity, and how much you want employees talking directly to the provider.
