WhosOff replaces paper forms, email chains, and holiday spreadsheets with a fast, transparent online system. Staff book leave in seconds; managers approve it with full context. No chasing, no confusion.
From request to approved - in a few clicks
Staff submit leave requests from any device; managers see the full team calendar, remaining allowances, and any approval rules before they decide. The whole process is tracked, timestamped, and auditable.
- Create unlimited custom leave types - holiday, WFH, training, medical, bereavement and more
- Set leave types to auto-approve for low-friction bookings like appointments or WFH days
- Staff can report a colleague's sick absence (up to one day) without manager involvement
- Block out public holidays or restricted dates to prevent conflicting bookings
- Super Users send gentle reminders to managers with outstanding approval queues
- Expired pending requests flagged automatically with approve-or-remove options
- Up to two additional notifiers per staff member - keep HR or a second manager in the loop
- Full audit trail of every request, decision, and who made it
Enforce your leave policies automatically - not manually
Inconsistent policy enforcement leads to conflict and coverage gaps. WhosOff bakes your rules into the system so they're applied every time, for everyone - no exceptions, no arguments.
Rules your team will actually follow - because they have to
Set minimum department staffing levels, carryover limits, notice periods, and staff-to-staff clash restrictions. WhosOff enforces them silently in the background every time a booking is made.
- Set how many staff can be off simultaneously per team
- Create staff-to-staff restrictions so key pairs can never clash on leave
- Configure carryover limits - max days allowed to roll into the next holiday year
- Yearly carryover tool automates the transfer process at year-end
- Set allowances per staff member and enforce them rigorously
- Block restricted days - public holidays, training days, peak trading periods
- Add bonus days for long service, manager benefits, or seniority rewards
- Investigate sick leave patterns with Bradford Factor reporting
Track every extra hour - and reward it fairly
Staff who go above and beyond deserve to be recognised. WhosOff logs overtime as it's approved, displays TOIL separately from holiday, and generates payroll-ready reports - so no one's extra effort falls through the cracks.
From late shifts to time in lieu - tracked automatically
Overtime works through the same intuitive flow as leave. Staff submit hours, managers approve, and TOIL balances update immediately - all visible from the dashboard without any manual calculation.
- Create custom overtime types - standard time, double time, weekend cover, on-call
- Offer time off in lieu (TOIL) instead of - or as well as - paid overtime
- TOIL balances shown separately from holiday allowances
- Managers can log overtime on behalf of staff from the administration area
- Conversion rate settings - 1:1 or enhanced rates (e.g. 1.5:1 for weekends)
- Export overtime reports to CSV/XLSX for payroll reconciliation
Your people data, all in one connected place
Staff Hub extends WhosOff from a leave tracker into a central home for everything you know about your team - employment history, salaries, certifications, contracts, policies, and emergency contacts. All connected to leave data, with no duplication.

Staff Hub is natively wired into leave, overtime, and absence data - so every corner of WhosOff talks to each other. Granular permissions mean each data type is controlled independently, down to the individual user.
