Clock-M
A multi-tenant SaaS platform for time tracking and team management — clock in/out, run projects, manage a team, and pull monthly reports.
Clock-M is a complete time-tracking and team-management product. People clock in and out, log breaks and trips, organise work into projects and tasks, run a team with proper roles and permissions, and export clean monthly reports — all in one place.
It’s multi-tenant: one account can belong to several team workspaces, and each team’s data stays cleanly separated. I built every layer myself — the database, the API, the web app, a mobile companion app, and the deployment that runs it in production.
Try the live demo
No signup needed — enter your email and I’ll send you a ready-to-use demo login for a fully populated team workspace.
Logs you straight into a populated team workspace — 6 people, ~2 months of time history, projects, tasks, clients, schedules and reports already filled in.
Time tracking
Clock in/out as work sessions, with nested breaks and trips. The live timer survives refreshes, restarts and the mobile app — it never drifts.
Monthly reports
Per-day work, break and trip totals with drill-down into individual sessions, plus one-click Excel export.
Projects & tasks
Projects with categories, links and docs; to-dos with priorities, statuses, due dates, assignees and drag-to-reorder.
Team workspaces
Multi-tenant by design: own or join multiple teams, with owner / manager / employee roles, email invitations and role-based permissions.
Absences & schedules
Request vacation or sick leave with attachments and a manager approval flow, and plan recurring shifts for members, clients and locations.
File storage
Nested folders, previews, downloads and public share links, backed by S3-compatible cloud storage with per-team quotas.
AI assistant
An in-app chat assistant with streaming responses and project/file context, powered by the Claude API.
Billing & GDPR
Stripe subscriptions with seat-based plans, plus self-service data export and account deletion. Available in 5 languages.
True multi-tenant data model
Every record (sessions, projects, notes, schedules, absences) is scoped to a person’s membership in a specific team — not just their user id. So the same person’s data stays cleanly isolated across all the teams they belong to.
Hand-written SQL, no ORM
All data access is hand-written, parameterized SQL on a shared PostgreSQL connection pool — full control over queries, joins and indexes. The schema is a normalized 34-table design with UUID keys and soft deletes.
Self-healing time tracking
Forgotten clock-ins are auto-closed (capped at 16 hours or end-of-day), and the live timer never trusts a local counter — it recomputes totals from server timestamps, so it’s drift-free across refreshes, restarts and the mobile app.
Direct-to-cloud uploads
The browser uploads files straight to object storage using short-lived signed URLs — the bytes never pass through the API server. Includes per-team storage quotas and client-side image compression.
Full auth lifecycle
Stateless JWT auth with email verification and password reset via single-use, expiring tokens. Account verification is re-checked on every request, not just at login — plus a founder-approval flow that stages destructive actions behind an email-confirmed token.
One contract for web & mobile
A single typed API client and shared types are reused by both the web app and the React Native mobile app — one source of truth for the whole API.
