Perfect pay is only possible
with clear, consistent,
accurate data
ZellisONE Pay tightly integrates payroll, absence processing, financial wellbeing and compensation to create payroll that drives business confidence, operational complexity, and employee clarity.

Real-time pay, real oversight
ZellisONE Pay delivers continuous recalculation, real-time anomaly detection, and smart payroll dashboards that empower pay professionals to act early.
With thousands of embedded validations, including automatic National Minimum Wage checks, we go above and beyond to automate your payroll to your specific needs, so every payroll run becomes a source of clarity and confidence, rather than last-minute concern.
Whether you’re handling multi-contract employees, unionised rules, pensions, benefits in kind, salary sacrifice, or industry-specific pay cycles, ZellisONE Pay adapts without breaking structure.
That’s why ZellisONE is trusted by some of the UK and Ireland’s most complex brands across healthcare, aviation, education, retail and government.
Engineered for pay confidence
Our advanced payroll engine has over a thousand built-in automated checks and surfaces anomalies with assistance from machine learning, to reduce errors and rework before payroll deadline.
High-volume, high precision pay runs with built-in validations and legislative compliance across UK, Republic of Ireland, Isle of Man, Jersey and Guernsey.
Real-time recalculation, pensions, salary sacrifice and benefits in kind, are just some of the features of ZellisONE Pay – the pay that payroll professionals trust.


Absence processing
Complex rules managed with ease.
Our technology looks at data for gaps, conflicts, or inconsistencies that could disrupt the pay cycle.
