HR and Payroll for Businesses with 100 to 250 Employees
One hundred employees is where many businesses discover that the HR platform they chose at fifty is no longer adequate. Reporting is inadequate. Multiple departments need different visibility. The HR team is growing and needs proper workflows rather than workarounds. Payroll complexity has increased further.
This is also the stage where businesses start to think about whether they need a dedicated HR information system (HRIS) alongside their payroll, or whether a unified platform can serve both. For most businesses of this size, the answer is: a good unified platform is better than two mediocre ones.
What This Stage Demands
Departmental structure: At 100+ employees, your organisation has departments — and each department head needs visibility of their team's HR data without access to everyone else's. Role-based permissions matter.
HR workflows: Leave approval flows, performance review cycles, onboarding sequences — these need to run systematically, not through individual managers improvising their own approaches.
Richer reporting: Absence by department, turnover by role, time to hire, headcount by location — the reporting needs become more specific and more operational.
Integration with finance: At this scale, the connection between payroll, headcount, and financial planning becomes important. HR costs are a significant budget line, and accurate data matters.
Multi-location support: Many businesses at this stage operate across multiple offices, sites, or even countries. The platform needs to handle this without breaking.
ERA 2025 Compliance at Scale
At 100-250 employees, gender pay gap reporting becomes a legal requirement (it applies from 250 employees, but building the data discipline earlier is advisable). ERA 2025's provisions around flexible working, zero-hours contracts, and day-one dismissal rights all apply and are increasingly complex to manage at this scale without systems.
