What Timesheet Handles
Time tracking, reports, invoices, exports, automation, HR rules, and AI logging in one system.
Simplified Time Tracking
One tap starts the timer on calculation work, another switches it to the site inspection, and the location is stamped on each entry.
- One-tap time tracking
- WLAN & Geofencing automation
- Scheduled break reminders
- NFC tag support
Project & Task Management
A project per commission, tasks for each work package and discipline, and one hourly rate per project so the fee basis stays unambiguous.
- Unlimited projects
- Task categorization
- Team collaboration
- Calendar integration
Accurate Feedback & Analytics
Hours by commission, work package and engineer, so the package absorbing the most time shows up while the drawings are still open.
- Daily, weekly, monthly reports
- Income tracking
- Trend identification
- Export to Excel & CSV
Professional Invoice Generation
Invoice per work package with the underlying entries attached, which is what the client's project manager asks for before releasing payment.
- Generate invoices from time entries
- Add expenses and notes
- Track payment status
- PDF export
Comprehensive Data Export
Export by project and date range to Excel for the fee calculation, or as a PDF that goes straight into the project file.
- Excel export
- CSV export
- PDF reports
- API access
Automatic Time Tracking
A geofence at the site boundary records inspection time on its own. A day of walkovers is logged rather than estimated back at the desk.
- Location-based tracking
- WLAN detection
- Background timer operation
- Persistent quick actions
HR-Ready Time Tracking
Working-time limits, overtime balances and leave for the whole office, visible in the weeks a submission deadline pushes people past their contracted hours.
- Contracts & employment models
- Live working-time limits
- Leave & overtime balances
- Absence requests & calendar
AI-First Time Tracking
Ask the assistant after a site visit: "Add 4 hours structural review to the Kestrel bridge", and it books against the right work package.
- Log time in one message
- Control the timer from chat
- Instant project answers
- Reminders, daily & weekly
