Staffology Payroll is IRIS's cloud payroll for UK businesses, and the old IRIS Payroll Business product page now redirects to it. Pricing is based on payslips processed each month: a flat fee of £43 per month covers 1 to 20 payslips, payslips 21 to 50 cost £2.15 each per month, and anything above 51 is quoted. All prices are subject to VAT. IRIS states that Staffology Payroll is HMRC recognised and has built-in checks to help you stay compliant, and that it handles specialist needs such as CIS and umbrella company payroll. Its API-first design and open API suit firms that want to connect payroll to an HR system or a data warehouse, and IRIS offers bespoke reporting on top of standard reports. The product holds ISO 27001, Cyber Essentials and ISO 9001 certifications. The £43 minimum makes it poor value for a tiny payroll, but the per-payslip model and quotes up to 10,000+ payslips mean it can grow with a business.
