Built for growing businesses 

Is IRIS right for a business like yours? 

  • Moving beyond payroll-only 

    You started with payroll, and now you’re ready to bring HR, and everything that comes with it, into one connected system. 

  • Replacing your first HR system

    The system you implemented early on has been outgrown, and you’re looking for something built for where your business is heading.

  • Formalising people processes

    Ad hoc ways of working are becoming formalised processes, and you need HR and payroll software that can standardise and support this change. 

Mid-sized business HR and payroll challenges

HR and payroll challenges when supporting 200–1,000 employees  

  • When you’re managing hundreds of people, disconnected HR and payroll systems hold you back, creating double-entry, increasing the risk of errors and limiting visibility of your workforce data.

    IRIS brings everything into one connected platform, giving you all the tools you need to better support your people in one place.

  • Trying to obtain a view of headcount, cost and workforce trends? Are the answers scattered across systems and spreadsheets that never quite agree?

    IRIS brings HR and payroll data together into one source of truth, giving you easily accessible reporting you can trust.

  • Too much of your time goes on manual tasks, such as chasing absences, updating records and answering routine queries.

    IRIS automates the repetitive work and puts everyday requests in employees’ hands with self-service, freeing you up to focus on more strategic work.

  • Keeping pace with all the changing workplace legislation is a full-time job in itself, and one your HR team can’t easily absorb.

    With IRIS, our software is automatically updated every time legislation changes, keeping your processes correct and compliant.

  • Hiring and holding on to good people is difficult, and as you grow, inconsistent onboarding or employee experiences across sites make it tougher still. 

    IRIS supports the full employee lifecycle, from hire to retire, so every new starter gets a consistent experience, wherever they join.
