Affinity vs ReadyTech – outsourced & managed payroll compared

Delivery footprint

Both providers are onshore-first, which narrows this comparison to architecture and depth rather than the onshore/offshore question that dominates comparisons against globally-delivered providers.

Calculation depth

ReadyTech's award engine is described as highly tuned for Australian modern awards and enterprise agreement calculations – a genuine strength built specifically for the AU regulatory environment. Affinity's rule builder covers the same ground with a complex automated engine handling intricate shift penalties, multi-tier EBAs, and allowances, on the same platform used for NZ.

For New Zealand, ReadyTech offers comprehensive Holidays Act tracking with automated adjustment modules – solid, purpose-built NZ compliance. Affinity's NZ engine is native to the same database as its AU engine, continuously tracking gross earnings, OWP, ADP, and leave liabilities, so a trans-Tasman employee's history carries across jurisdictions without a data handoff.

Both provide native STP Phase 2 reporting, SuperStream clearing, and state payroll tax handling on the AU side, with ReadyTech adding state payroll tax calculations explicitly and Affinity adding Pay Day Super readiness and NZ IRD Payday Filing on the same statement. The lodgement scopes are comparably deep for an AU/NZ-only operation.

Audit, QA & who owns support

ReadyTech runs structured Level 1–4 compliance audits – input, gross-to-net, variance, and post-finalisation checks – a formal, staged audit methodology. Affinity's approach layers automated pre-payslip checking (Payroll IQ) with dedicated local payroll manager variance audits – automated detection plus a named human reviewer rather than a fixed audit-level structure.

On support, this is where ReadyTech stands out among outsourced providers: it offers a dedicated employee phone and online helpdesk that directly manages staff queries, backed by a dedicated onshore payroll specialist and client account manager. This is one of the few outsourced payroll providers matching Affinity's direct-ownership model rather than routing Tier-1 back to the client's HR team.

Affinity's local AU/NZ team also owns Tier-1 employee queries directly, with a named local Payroll Manager as the primary escalation point. The practical difference for your organisation is less about whether employees get a direct line – both providers offer that – and more about depth of configuration and platform unification behind the scenes.

Banking & who carries the liability

ReadyTech offers end-to-end payment distribution through client bank accounts or bureau trust distribution – client-controlled or provider-managed, depending on the engagement. Affinity operates a provider-managed trust and disbursal model by default: Affinity executes net pay, ATO, IRD, and super fund payments directly or via ABA files.

Regardless of which banking or disbursal model is in place, statutory payroll compliance liability under the Fair Work Act 2009 (Australia) and NZ employment law is non-delegable to a third party. The employer remains accountable for underpayments, late payments, and compliance failures even where a provider executes the actual transaction.

Retained resourcing & implementation

On paper, retained FTE and implementation velocity are identical between the two providers. The choice here comes down to platform architecture (single unified database vs a multi-product portfolio) and which provider's specific award and Holidays Act configuration best matches your workforce.

Where ReadyTech excels

ReadyTech is a strong onshore AU/NZ specialist in its own right, with genuine strengths worth weighing.

Where Affinity excels

Affinity's advantages sit in platform unification and the pairing of automated intelligence with named human accountability.

Who's each provider best for?

Both are onshore AU/NZ specialists offering direct Tier-1 support, so the decision comes down to platform architecture and specific award/entity fit.
