HR as a Service (HRaaS) is an operating model that brings HR administration, payroll, compliance, and advisory together under a single provider, shared data model, and clear ownership.

Traditional HR outsourcing usually splits these responsibilities across multiple vendors, with your internal team acting as the coordinator between them. HRaaS removes that fragmentation.

This difference is important because many HR issues stem from disconnects between systems and providers, especially between HR administration and payroll. When those handoffs disappear, so do many of the manual checks, errors, and delays. Instead of managing vendors, your HR team can focus on driving business priorities.

HR professionals spend up to 57% of their time on administrative work. That’s not something you fix by hiring more people or reskilling; it’s a structural issue. As long as transactional work dominates, strategic priorities tend to fall behind.

HRaaS shifts that operational workload to a managed service with clear service levels and accountability. Your internal team still owns HR strategy and policies, while execution is handled externally.

In practice, organisations often find that initiatives like workforce planning, talent development, and organisational design only gain traction once the day-to-day operations are running smoothly in the background.

Yes. Supporting multi-country operations is a core part of the HRaaS model. It is built to handle complexity from the start, not added on later.

Zalaris operates in over 150 countries and includes local regulatory expertise within its delivery model. This covers employment law, works councils, and statutory reporting, all managed within a consistent global framework.

This becomes especially important as organisations expand and adopt AI. While AI can speed up how work gets done, it also increases risk if compliance foundations are not solid. HRaaS helps maintain control by embedding compliance into daily operations, rather than reacting after issues arise.

HR Partner Plus is the on-demand HR Business Partner component of the HRaaS model. It gives organisations access to experienced HR professionals who understand their business, workforce, and regulatory environment.

It’s particularly useful when the need for senior HR support fluctuates. This might include mergers and acquisitions, restructuring, entering new markets, navigating complex compliance situations, or covering leadership gaps.

Instead of choosing between overstretching internal teams and committing to full-time hires, organisations can scale HRBP support up or down based on actual demand, without adding fixed headcount.

No. HRaaS works with your existing HRIS, whether that’s SAP SuccessFactors, Workday, HiBob, or another platform. It adds the operational structure and governance needed to get more value from what you already have.

This helps address a common challenge in HR transformation. Large HRIS implementations can take 18–24 months in complex organisations, and they often automate existing processes without improving how work is actually delivered.

HRaaS complements your system by adding managed services, clear accountability, and integrated payroll. That way, you can realise the intended return on your technology investment without going through another system replacement.
