Two interfaces, one system

When time tracking runs on scattered processes

Spreadsheets, messages, separate documents, and manual reviews make it hard to track working hours and eat up administrative time.

Sello is built to make organizing, tracing, and reviewing time records straightforward.

A connected platform for managers and employees

Managers run the team from the web dashboard, and employees clock in from the app. The data stays centralized and available for review.

A dedicated installation for each client

Sello is deployed as an independent, self-hosted installation per client — not as a shared multi-tenant SaaS platform. Each deployment manages its own data and users.

Features

The names, employees, and data shown in the screenshots are fictional and used solely for demonstration purposes.

Web dashboard

  • Manage employees, holidays, and time off.
  • Append-only clock-ins: every correction inserts a new event linked to the original, with an author and reason — a record is never edited or deleted.
  • Roles and permissions for admins and employees.
  • Real-time view of who's currently clocked in.
  • Reports exportable to PDF and CSV, ready to show an inspector or hand to an employee.

Android app

  • Start and end the workday with one tap from the home screen.
  • Clock-in history with offline caching: if the device has no connection when clocking in, the event queues up and syncs once the connection returns.
  • Access to user data, time off, and schedule.
  • Optional geofencing: notifies when entering or leaving the workplace radius, without ever clocking in on the user's behalf.
