Managing Complexity with Confidence
Every month, four payrolls need to run like clockwork.
1,300 people expect to be paid. Questions come in. Reports go out. Audits appear.
Vodafone Ireland is part of Vodafone Group, a global telecommunications leader operating in more than 20 countries. The Irish operation employs over 1,300 people, and payroll accuracy is absolutely critical.
Vodafone’s HR operations are structured as a global vertical meaning Petra and her team report into Vodafone Group in the UK, not through a local leadership chain. They also receive support from Vodafone’s shared services organisation in India, VOIS (Vodafone Intelligent Solutions), which handles centralised admin and advisory functions.
Zellis fits seamlessly into this matrix, supporting local delivery while aligning with a global standard.
In the middle of it all: Petra Kaszás, HR Operations Lead at Vodafone Ireland, calmly managing a process that rarely makes headlines, but powers everything.
Behind her is a partnership built on rhythm and trust. Vodafone and Zellis have worked together for over a decade. There’s no drama. Just a shared understanding of what it takes to get payroll right, every time.
The setup is complex. Vodafone Ireland’s payroll team is just four people. They handle high volumes, constant compliance requirements, and escalating employee queries.
Payroll in Ireland has to be delivered in a way that integrates seamlessly into the wider Vodafone structure, meeting group-wide reporting expectations and governance standards.
The daily orchestration of a thousand moving parts keeps the pressure constant. Payroll has to be accurate, compliant, and responsive to evolving needs. And there’s no buffer for mistakes.
Petra’s role is to keep everything moving smoothly, and that means having total trust in the systems and people supporting her.
For over ten years, that’s been Zellis.
The Power of Partnership in Everyday Excellence
Zellis provides a fully managed payroll service tailored to Vodafone’s exact needs. That includes data entry, processing, validations, approvals, and digital payslips via ResourceLink.
But the value goes far beyond processing.
Vodafone employees have access to a dedicated helpdesk for payroll queries, including everything from Revenue notifications and pension contributions to benefit questions. The volume is high, but the pressure isn’t felt in-house because Zellis absorbs it all.
On one occasion, Petra needed historical payroll data for a legal query. She flagged it in the morning. The full, validated audit trail landed in her inbox before lunch.
These small wins add up to a quieter inbox, fewer escalations, and the kind of trust that builds over time.
Zellis works closely with Vodafone Ireland’s payroll specialist, who manages the day-to-day flow of tasks, including payroll cycles, data checks, validations, and standard queries. That relationship is deeply embedded and operates almost as an extension of the in-house team.
Petra herself is only involved in more complex or escalated queries, typically on a weekly basis. When she does need to step in, Zellis responds fast and confidently, often turning things around within the hour.
She also occasionally requests non-process-related data, such as historical records or documentation for internal projects and always receives what she needs, quickly and accurately.
From Confidence to Capacity
Zellis plays a key role in supporting Vodafone’s audits, reporting, and compliance responsibilities, giving Petra and her team the tools to deliver with precision and peace of mind.
The payroll system is highly automated, performing over 400 built-in checks to ensure accuracy and consistency.
As a senior leader in a global function, Petra also values the visibility and speed of data access. When she needs to step outside of regular payroll operations whether for internal reviews, legal documentation, or senior reporting, Zellis provides fast, structured responses.
That level of responsiveness helps her and Vodafone’s HR team stay proactive, and work with confidence, free from last-minute scrambles or second-guessing.
Zellis’ dedicated team member, Catherine, has supported Vodafone since the beginning of the relationship. Petra describes her as someone who “knows our payroll better than we do,” a trusted constant in a fast-moving organisation.
And while today’s operations run smoothly, there’s more to come. Vodafone is considering a move toward a global payroll model and the stability and support Zellis provides in Ireland shows what’s possible at scale.
