Inside the research

NelsonHall’s assessment points to Zellis’ 60+ years of payroll experience and deep expertise, alongside the scale and resilience to support organisations of different sizes and complex payroll requirements. It also highlights Zellis’ significant UK and Ireland presence, paying around one in every six workers.

Technology and innovation are another important part of the assessment. NelsonHall highlights Zellis’ use of AI-driven anomaly detection, continuous data validation, Payroll Insights and Intelligent Payslips, alongside continued investment in AI and API-enabled cloud platforms.

This builds a picture of a payroll provider combining longstanding expertise and scale with applied AI for real work, helping organisations make payroll more accurate, efficient and ready to adapt to change. The “Applied AI for real work” positioning is one of the core pillars of the Worklife Reinvention messaging.

Built for today and what comes next

Organisations are under pressure to deliver more, adapt faster and manage greater complexity, while keeping critical services like payroll running reliably and efficiently. This reflects the Worklife Reinvention framing of the pressures organisations and their people are navigating.

The NEAT assessment doesn’t look only at current capabilities. It also considers providers’ ability to meet future client requirements, including investment, innovation, agility and the ability to support customers over the lifetime of a contract.

NelsonHall highlights Zellis’ plans to continue investing in AI-enabled payroll, including predictive exception detection, richer payroll insights and compliance alerts, as well as bringing HR, Workforce Management, Pay, Talent and Benefits together through ZellisONE.

It is this combination of established payroll expertise and continued innovation that underpins Zellis’ position as a Leader in the Overall market segment, providing a trusted foundation for organisations looking to reinvent how work gets done. That “trusted foundation” and reinvention of how work gets done are central themes in the Worklife Reinvention messaging.
