How to choose PTO & leave management software
6 criteria · Requirements by company size · 5 red flags
A PTO tool is only useful if balances are right. Evaluate how it models your policies and how it hands data to payroll.
Bring your actual policy documents to the demo and ask the vendor to configure them live.
Accrual rule flexibility
Policies vary by tenure, hours worked, carryover, caps and waiting periods, and rigid rules force workarounds.
Policy variation by group and location
State and local rules differ, and so do company policies by role.
Payroll and HRIS sync
Balances and paid time off must reach payroll correctly or pay is wrong.
Statutory leave tracking
FMLA eligibility and the 12-workweek entitlement must be tracked with documentation.
Approval workflow and coverage visibility
Managers need to see who else is out before they decide.
Time clock and scheduling integration
Hourly workforces need time off reflected in schedules and hours.
