IRIS Software Group builds UK-focused business software for accountancy, payroll, HR and education, serving over 100,000 organisations across 135 countries.
IRIS Software Group is one of the United Kingdom's largest privately held software companies, building critical business software for accountancy, payroll, HR and education. The company serves more than 100,000 organisations and has a presence in 135 countries, though its heaviest footprint remains in Britain: its payroll software processes pay for one in every six UK employees, its accountancy products are used by 91 of the top 100 UK accountancy firms, and its education software supports more than 12,000 schools across the country.
The product line runs from practice management and compliance tools for accountancy firms to payroll processing systems that form part of the operational backbone for employers, alongside HR software designed to streamline workforce administration and keep organisations compliant. Education solutions cover the administrative and operational needs of schools and the wider education sector.
Technical work spans AI-powered automation, business software platforms, data capabilities and compliance software. The company describes a focus on combining industry expertise with automation to help customers run more efficient operations, while continuing to expand internationally without disrupting the reliability that dependent organisations require of its systems.
