Two triggers: threshold overtime kicks in once an employee exceeds a set number of hours per day or week. Time-of-day overtime pays a premium for hours worked in a specific window (e.g. after 6pm or before 6am), regardless of total hours. Two pay methods: a rate multiplier (e.g. 1.5×) or a fixed hourly rate for overtime hours. Stack multiple rules, build tiers, and configure each employee independently.

Entirely optional — only enable it if you need it. When on, employees split their hours across projects when submitting (e.g. 3h on Client A, 4h on internal work). You can add a billing rate per project (charged per hour) or a flat fee per entry (useful for callouts or site visits). Managers get a clear breakdown of where time is actually going.

An optional alternative to paying overtime — enable it only if you want to offer time off in lieu instead of (or alongside) extra pay. Set a TOIL conversion rate (e.g. 1h overtime = 1.5h leave) and overtime hours automatically accrue as a TOIL balance — no manual tracking. TOIL is kept separate from annual leave so it never eats into holiday entitlement. Employees book it the same way they book any other leave.

Managers approve or reject timesheets from any device — phone, tablet, or desktop. Rejections include a written reason so employees know exactly what needs fixing and can resubmit. Managers can see who has not submitted for the period, and are emailed as each timesheet comes in. Pay totals are calculated automatically from approved hours — no manual maths at payroll time.

Two submission modes — employees use whichever fits their workflow. Clock-in mode starts a live timer the moment they begin their shift. The timer runs in the background even if the app is closed, so no hours are lost. Form mode lets them enter start time, end time, and breaks at the end of the day or week. Both work on mobile and desktop.

Set each employee's own hourly rate and pay totals are calculated automatically from their approved hours. Scope managers to their department so they only ever see their own team's data. Want to keep salaries private? Hide pay rates and totals from managers entirely — they see hours, but never figures. Full control over who sees what.

Send approved timesheets to payroll in a few taps. Export to CSV, Xero, or QuickBooks — filter by date range, employee, or department, and choose exactly which columns to include. You can combine timesheet and leave data in a single export so your payroll software gets everything it needs in one file.
