How It Works:
Zero-Friction Leave Management
Most HR software forces you to create accounts, manage passwords, and pay extra licenses for every single employee just so they can book a day off. Trefnus Staff keeps it beautifully simple and completely private by putting the manager in total control.

Quick Setup
Install the app on your device, set up your custom leave year, and add your team members along with their annual allowances. No employee invites or email verifications required.
Step 2
Employees Request Leave
Staff request time off via email, message, or our printable cards. This physical system is perfect for team members who struggle with technology, avoiding tricky app log-ins.
Step 3
Log & Verify Instantly
View the team calendar on your dashboard to check coverage. If the request works, log it with one click. The app instantly updates their remaining holiday balance.
