About IRIS HR
A UK HR platform from the IRIS payroll group, reported on like an enterprise.
IRIS HR is the cloud HR product (also marketed as Staffology HR) inside IRIS Software Group, the UK accountancy, payroll and HR house founded in 1978 and headquartered in Slough. The group reports more than 100,000 customers across 135 countries and processes payroll for roughly one in eight UK employees through its various payroll lines. It is jointly owned by Hg, Intermediate Capital Group and Leonard Green & Partners following a 2024 recapitalisation, and Hg has held a stake in IRIS for most of the past two decades.
The HR platform itself is aimed at growing UK businesses and covers the standard HRIS surface: the core employee record and contracts, absence and leave (holiday, sickness, compassionate, overtime), time and attendance, performance reviews and objectives, expenses, compensation and benefits, training and L&D, and a self-service portal for employees and managers. It sits next to Staffology Payroll, IRIS Cascade HR and the IRIS accountancy stack, so for a lot of UK SMBs it is the HR seat in a wider IRIS estate. The open API exposes the same employee, employment, absence and reporting objects the in-app screens use, with webhooks for change events, which is what we connect to when we land your IRIS HR data in the warehouse.
