Leonardo
“Working with Zellis has already made a huge difference to how we work and the quality of the payroll and HR services we deliver to our employees. We’re looking forward to further strengthening our partnership over the months and years to come”
Rexel
"The Payroll Calculate task has been painful for many years, and during the early part of this year, we were experiencing up to 4 hours processing time. Following our system health (improvement work) we reduced the calculate process to 20 minutes. Now (we have) set up offline processing on the specific processing tasks, we have reduced the processing time by another 15 minutes. Therefore 5 minutes is extraordinary for us. Fantastic result!"
BUPA
"We know with Zellis, that the technology is underpinned by a market-leading provider. It’s amazing to see that partnership of tech and strategy delivered to our employees."
