Real stories, real results
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!"
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.”
Monmouthshire County Council
“There is a strong synergy between our digital transformation plans and Zellis HCM Cloud – especially its focus on employee experiences, automation, and ease of integration with solutions we already use.”
