Support your HR and Payroll team where it matters most

Application Maintenance Service (AMS) gives you an agreed volume of specialist Zellis time each year, delivered by a named team that learns your configuration and stays with your account. That time covers the system work behind your HR and Payroll platform, configuration, hierarchy maintenance, small changes and ad-hoc reports, proactive housekeeping and monitoring, user access and security administration, and support through releases. We carry out the system work; your team retains ownership of compliance, data and decisions.

Support fixes things if they break. AMS keeps the platform moving. It covers the routine maintenance, configuration and small change work that usually sits in the gaps between pay runs and gets deferred when the team is busy. Alongside that, proactive housekeeping, routine monitoring, task scheduling and automation keep the platform clean and ready, so fewer issues reach your team in the first place.

AMS Lite is designed for Managed Service customers who need essential application maintenance: application security, configuration, hierarchy maintenance and small changes. Standard AMS is designed for SaaS customers who need broader system administration cover, everything in AMS Lite, plus incident and alert handling, releases, housekeeping and a system evaluation. Both are delivered by the same specialist team, and we will help you identify which level fits your operating model.

A new hire can be difficult to find, expensive to retain and still needs time to learn your configuration. A third-party provider may bring broad experience, but they are still working from the outside in. Only Zellis built your platform, so we understand not only what the system does, but why it works the way it does: which configuration dependencies may create issues, which routine maintenance and small changes can be made with confidence, and what is coming next, because we are helping to build it. AMS gives you that expertise as a dedicated team, without the challenges of recruitment, onboarding or key-person dependency.

AMS is fast by design. Minor changes and ad-hoc reports are ready for customer testing within five working days, and we measure ourselves against that on every request. Larger pieces of work are scoped with you first, so you know what to expect before it starts. And when something unusual happens, the people who wrote the product are not hidden behind another organisation’s support process, they are part of the same business, which means faster answers and fewer delays.

Yes. Testing as a Service is available alongside AMS and provides structured testing around upgrades, legislative change and year-end. It gives you clear, documented evidence of what has been tested and flexible capacity at the points where internal demand is highest, so releases and statutory change can be adopted with confidence rather than absorbed by your team on top of the day job. It can be taken with either AMS Lite or Standard AMS, and we will scope the right level of testing support with you.

Yes. AMS is delivered by a named team rather than a single individual, so knowledge of your configuration is held collectively and stays with your account, removing the key-person risk that builds when one or two people hold the knowledge of how your system is actually set up. The service includes specialists with more than 18 years’ tenure, and the team behind AMS brings more than 140 years of combined Zellis experience. That same team adds expert capacity at the moments that matter, including year-end, pension re-enrolment and salary review, without permanent overhead.

AMS uses inclusive annual volumes designed to cover typical change demand at a predictable cost, so there are no surprises through the year. Pricing depends on the level of service, AMS Lite or Standard AMS, and your operating profile, and is scoped and agreed with you up front.
