Meet ELLA, our human-first AI assistant
AI is exciting, but even so, we never lose sight of what really matters: people.
When it comes to HR, Workforce Management and Pay, AI works best as a quiet, supportive partner that seamlessly adapts to people’s needs.
ELLA is our conversational AI assistant, built with people at the centre.
It uses natural language, quickly learns what works for you and flags risks early.
Available 24/7, ELLA helps employees, managers and administrators work smarter and faster with helpful nudges and intelligent actions.
ELLA also meets AI regulations in the UK, Republic of Ireland, EU and USA and has built-in boundaries for how it assists, summarises, recommends and takes action.
Next-level business intelligence with ZIP
Our Intelligence Platform centralises and analyses data from all your Zellis solutions.
Then it sends real-time insights to those who need them via self-service notifications, mobile alerts and visual dashboards.
To adapt swiftly to changes in the business landscape, our platform gives you an accurate view of workforce trends that enables you to make strategic, data-driven decisions that are supported by a single source of truth.
You’ll wonder how you ever did without it.

Real stories, real results

St Helens Metropolitan Borough Council
"We‘re looking forward to intelligent payslips so that our employees have the knowledge and the ability to better understand their payslips. We can use these to better support our employees across the council.”

Vertas
“With Vertas acquiring bigger and bigger companies, we needed better reporting, and Zellis is giving us this capability. It’s really important for us to see information across all functions, not just in payroll, though. So, we will continue to harmonise our systems to get the very best visibility, with all information accessible in one place.”
