Can managers approve timesheets before invoicing?

Yes. The approval workflow lets team leads review weekly timesheets and flag corrections before the data is locked for billing.

Can I set different billing rates per project or person?

Yes. Billing rates are configured at the project level and can be overridden per team member. The system applies the correct rate when generating invoice line items.

How are utilization reports calculated?

The system calculates billable utilization as billable hours divided by total logged hours, shown by team member and period. You can filter by client, project, or date range.

Build a Time Tracking Software with AI - in Hours

ProjectCode generates a complete, production-ready Time Tracking Software from a single natural language prompt. In hours instead of months, you get a React frontend, NestJS REST API, PostgreSQL database, and authentication - fully integrated, live-previewed, and deployed to a URL you own.

Estimated build time: 2–4 hours

The Challenge

Why building a Time Tracking from scratch is hard

Building a Time Tracking Software from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing time tracking-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Time Tracking needs

ProjectCode generates a production-ready Time Tracking with all the modules your team needs from day one.

One-click timer with project and task tagging

Manual time entry with date and duration

Weekly timesheet view with approval workflow

Billable vs non-billable time categorization

Client and project-level billing rate configuration

Reports: utilization by team member, billable hours, overtime

CSV and PDF timesheet export for client billing

Integration hooks for invoicing on logged hours

Architecture

How it's built

The generated Time Tracking follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for time tracking workflows

NestJS REST API with dedicated time tracking modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all time tracking entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live time tracking status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Time Tracking

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

time_entries (id, user_id, project_id, task_id, date, duration_minutes, description, billable, approved)
projects (id, name, client_id, billing_rate, budget_hours, status)
timesheets (id, user_id, week_start, entries jsonb, total_hours, status, submitted_at, approved_by)
billing_rates (id, project_id, user_id, rate_per_hour, effective_from, currency)

FAQ

Common questions about building a Time Tracking

The generated app uses localStorage to persist timer state, so a running timer survives page refreshes and brief network interruptions. Full offline sync can be added as an extension.
