Staffology Payroll Review 2026: IRIS Cloud Payroll for UK Businesses

Staffology is a cloud-native UK payroll platform now owned by IRIS Software Group, one of the UK’s largest providers of accountancy and payroll software. With 53,000+ employers using IRIS payroll products and 1.4 million UK employees managed through the platform, Staffology has become IRIS’s flagship cloud payroll solution — replacing legacy desktop products that are being discontinued in 2026.

This review covers Staffology’s payroll features, pricing, strengths, and limitations for UK businesses — based on verified HMRC compliance data, published pricing, and real user feedback from across the IRIS ecosystem.

Staffology Payroll at a Glance

Staffology is an HMRC-recognised cloud payroll platform from IRIS Software Group, starting at £39/month for up to 19 payslips. It is best suited to UK SMEs and accountancy practices running payroll for multiple employers.

Key Features

Staffology’s standout features are its cloud-native architecture and full REST API, making it one of the most developer-friendly payroll platforms available in the UK.

Unlike many competitors that migrated legacy desktop software to the cloud, Staffology was built as a cloud application from scratch. This matters because cloud-native platforms tend to be faster, more reliable, and easier to update than retrofitted desktop products. There is no desktop installation, no local data to back up, and no version compatibility issues.

The REST API is Staffology’s most distinctive feature. It allows developers, accountancy practices, and software companies to embed payroll functionality directly into their own applications. This is particularly valuable for payroll bureaux and accountancy firms that want to integrate payroll processing into their existing practice management software without switching between separate systems.

For day-to-day payroll processing, Staffology covers the essentials:

• Automated RTI submissions — Real Time Information sent directly to HMRC
• Auto-enrolment — workplace pension management with PensionSync integration for automated pension submissions
• CIS compliance — Construction Industry Scheme deductions and reporting
• P60 and P11D — year-end reporting and benefits-in-kind documentation
• Multi-employer support — run payroll for multiple businesses from a single account (ideal for bureaux)
• Employee self-service — staff can view payslips and tax documents online

Staffology HR is available as a separate module, covering employee records, absence management, and document storage. However, the HR capabilities are limited compared to dedicated HR platforms like BambooHR or Employment Hero. If you need comprehensive HR alongside payroll, Staffology’s HR module works for basics but will not replace a full HRIS.

Pricing

Staffology Payroll starts at £39/month for up to 19 payslips, with additional payslips at £1.95 each. Pricing is per payroll run, not per employee.

Staffology publishes transparent pricing for its core payroll product:

To put this in context, here is what a typical business would pay:

• 10 employees: £39/month (£468/year)
• 30 employees: £39 + (11 × £1.95) = £60.45/month (£725/year)
• 50 employees: £39 + (31 × £1.95) = £99.45/month (£1,193/year)

This pricing model is competitive against Sage Payroll (from £20/month for 10 employees) for smaller teams, though Sage becomes cheaper at scale because its per-employee add-on rates are lower (£1.30–£5.30 depending on tier). For larger businesses (50+ employees), get quotes from both and compare the total annual cost for your specific headcount.

The pricing is per payroll run, not per employee. If you pay staff monthly, the cost is as stated. If you run weekly payroll, you will be paying per run — clarify this with IRIS before signing up, as it materially affects your annual cost.

The IRIS Acquisition and KashFlow Connection

IRIS acquired Staffology in 2021 to replace its ageing desktop payroll products. KashFlow is a separate IRIS bookkeeping product, not the same as Staffology payroll.

Staffology was founded in 2015 as an independent cloud payroll startup. In 2021, IRIS Software Group acquired Staffology to accelerate its transition from desktop to cloud payroll. IRIS had been selling desktop payroll products (IRIS Payroll Basics, IRIS Payroll Professional, IRIS Bureau Payroll) for decades, but these legacy products were reaching end-of-life.

The acquisition strategy is now clear: IRIS Payroll Basics is being discontinued in April 2026, and its 53,000+ employer customers are being migrated to Staffology. This makes Staffology the future of IRIS payroll — not a niche product, but the platform that will serve the majority of IRIS’s UK payroll customer base.

A common source of confusion is the relationship between Staffology and KashFlow. KashFlow is a separate IRIS product focused on bookkeeping and accounting — it is not a payroll platform and not related to Staffology. If you are looking for payroll, Staffology is the IRIS product you want. If you need accounting software, KashFlow (or Xero/QuickBooks) is the right category.

The staffology.co.uk website now redirects to iris.co.uk, confirming that the Staffology brand has been fully absorbed into the IRIS product family. You will find Staffology Payroll listed under IRIS’s product catalogue rather than as a standalone brand.

Who Is Staffology Best For?

Staffology is ideal for UK SMEs wanting cloud payroll with strong HMRC compliance, and for accountancy practices needing API-driven multi-employer payroll.

Staffology works well for:

• UK SMEs (1–50 employees) wanting a modern cloud payroll platform with transparent pricing and HMRC compliance built in
• Accountancy practices and payroll bureaux that need to process payroll for multiple employers from one platform — the API and multi-employer support are genuine strengths here
• Businesses migrating from desktop payroll (BrightPay desktop, Sage 50, IRIS Payroll Basics) who want to move to cloud without losing UK compliance features
• Developers and software companies that want to embed payroll functionality via API into their own applications

Staffology is NOT right for:

• Businesses needing comprehensive HR — the HR module is basic. Consider Employment Hero (free payroll + full HR) or BambooHR instead
• Global payroll needs — Staffology is UK-only. For international payroll, look at Dayforce or ADP
• Businesses wanting managed/outsourced payroll — Staffology is self-service software. If you want someone else to run your payroll, consider Cintra or Moorepay
• Very large employers (500+) — pricing becomes bespoke and you may find better value with enterprise platforms

Pros and Cons

Staffology excels as a modern, API-first UK payroll platform with transparent pricing, but its HR features are limited and the IRIS brand absorption creates identity confusion.

Staffology vs Alternatives

Staffology competes directly with Sage and BrightPay for UK SME payroll. Its API gives it an edge for tech-savvy businesses, while Sage wins on name recognition and scale.

Staffology vs Sage: Sage is cheaper at the entry level (£20/month vs £39/month) and benefits from stronger UK brand recognition. Staffology’s advantages are its API, modern cloud-native architecture, and multi-employer support for bureaux. For a straightforward 10-person payroll, Sage is likely the simpler and cheaper choice. For an accountancy practice managing 20 clients’ payroll, Staffology’s bureau features and API give it a clear edge.

Staffology vs BrightPay: BrightPay offers the lowest entry cost (£69/year for up to 3 employees) but its desktop product is being discontinued after the 2025/26 tax year. BrightPay’s cloud pricing is custom and not yet published. If you are currently on BrightPay desktop, Staffology is a natural migration path — both are cloud-native and HMRC-compliant, and Staffology’s pricing is transparent. Moneysoft is another affordable option for straightforward small-team payroll.

Staffology vs Employment Hero: Employment Hero offers free payroll (with paid HR plans from £90/month minimum). If you need both payroll and comprehensive HR, Employment Hero provides better value as an all-in-one platform. If you only need payroll and value API access, Staffology is the better specialist choice.

Our Verdict

Staffology is a solid, modern UK payroll platform with transparent pricing and genuine API capabilities. The IRIS backing provides scale and compliance confidence, though the brand transition creates some confusion.

Staffology occupies a sensible position in the UK payroll market: modern enough to compete with cloud-first competitors, established enough (via IRIS) to be trusted with compliance-critical payroll. The combination of transparent pricing, cloud-native architecture, and a genuine REST API gives it clear appeal for businesses that value flexibility and integration capabilities.

The IRIS backing is a double-edged sword. On one hand, it brings 53,000+ employer relationships, ISO 27001/9001 certifications, and HMRC recognition across multiple payroll products. On the other, the brand absorption (staffology.co.uk now redirects to iris.co.uk) means you are effectively buying an IRIS product — and the ongoing migration of IRIS Payroll Basics users to Staffology may strain support resources in the short term.

The Trustpilot rating of 4.0/5 (3,428 reviews) for IRIS as a whole is encouraging, though individual reviews cover the full range of IRIS products, not just Staffology. User feedback specifically about Staffology tends to be positive on the cloud experience and API, with occasional frustration about features that are available in legacy IRIS products but not yet in Staffology.

Our recommendation depends on your situation:

• UK SMEs (1–50 employees) wanting dedicated payroll without the complexity of an all-in-one HR platform — Staffology is a strong choice at £39/month
• Accountancy practices and bureaux — Staffology’s multi-employer support and API make it one of the best options in this category
• Businesses currently on IRIS Payroll Basics — migrating to Staffology is the natural and supported path, given the April 2026 discontinuation
• Businesses needing HR + payroll — consider Employment Hero or Sage HR instead, as Staffology’s HR module is limited

Pricing verified via IRIS product pages (February 2026). HMRC recognition verified via the official HMRC register. Trustpilot rating for IRIS Software Group verified February 2026. KashFlow is a separate IRIS bookkeeping product, not related to Staffology payroll.
