Factorial

Factorial charges From £5.40/emp/mo with no monthly base fee, under a per-employee modular pricing structure and no long-term contract requirement. Modules beyond core HR, such as time tracking, recruitment, and learning management, are included rather than priced as costly extras, which keeps the overall bill predictable as you add functionality.

Factorial is a Spanish company, and its stated target market is EU and UK SMBs with 10 to 200 employees. UK employment law coverage is rated as supported rather than strong, and right to work checks are rated limited, so UK-specific compliance depth is lighter than a UK-built platform such as Sage HR or Breathe.

Factorial does not run payroll natively; UK payroll is handled through an integration rather than inside the platform. Pension auto-enrolment likewise flows through that same integration rather than being calculated natively, so businesses should confirm which payroll partner Factorial connects to before relying on it for PAYE.

Factorial includes a native AI layer called Factorial One, built into the core platform rather than sold as an add-on. Further automation into external AI agents currently runs through third-party tools such as Zapier rather than an official MCP connection, so first-party AI-agent access is not yet available.

Factorial includes a built-in applicant tracking system and a learning management module as standard, alongside time tracking, performance reviews, and document management. This breadth at a flat per-employee rate makes Factorial a reasonably complete HR suite for growing SMBs that want ATS and LMS without paying separately for each capability.

Yes. Factorial integrates with Xero, Slack, and more than 100 other tools, giving UK businesses a route to keep HR and accounting data aligned without manual exports, though Sage users should confirm connector availability directly given Xero is the named accounting partner.
