Implementation Services

Where technology meets people and purpose

Zellis Programme Implementation experts partner with you to configure ZellisONE, connecting technology, people and purpose.

Surface the data and insights that you need

Forget a one-way “build to spec” service.

We offer a collaborative approach that sets your organisation up for better leadership, better performance, and measurable results.

Configured by programme transformation experts

Our powerful reports support regulatory compliance and worker wellbeing, and alert you to ‘at risk’ employees.

Fatigue risk monitoring

Use Workforce Management patterns, payroll overtime and sick days to model fatigue exposure to identify where long shifts, low rest days and high absence overlap.

Pay volatility score

Track how variable an employee’s income is month-to-month/week to week. Identify employees at risk of financial stress or predict retention issues.

Workforce compliance monitoring

Track right-to-work dates, visa expiry, mandatory training, and payroll activity to spot non-compliance where people are still paid or scheduled despite expired certifications, training or visas.

Make ZellisONE your insights engine

Once configured, your platform becomes more than just an operational tool – it transforms into an insights engine for your organisation.

By connecting and analysing data across hr, pay, and workforce management, it uncovers patterns and risks that were once invisible.

Our experts will configure powerful, role-specific reports that put these insights at your leaders’ fingertips, enabling them to lead with foresight, not hindsight.

Don’t just take our word for it

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.”
