Time Tracking System: Mobile App with GPS and ERP Integration
Mobile time tracking for field service, trades, and project work – with app, GPS, and ERP integration.
Time Tracking System Development
Why a Custom Time Tracking System?
Standard time tracking tools like Clockify, Toggl, or similar often fail with special requirements: offline capability on construction sites without cell reception, GPS proof for clients for accurate hourly billing, complex shift models with surcharges, or integration into your existing system landscape like DATEV or SAP. A custom time tracking system solves exactly these problems.
We develop mobile time tracking apps for field service and tradesthat work even without internet and synchronize automatically. GPS tracking for construction site hours provides seamless proof for client billing. Integration into DATEV, SAP, Odoo, or Lexwareautomates your payroll processing and saves hours of manual data entry.
Since the Federal Labor Court ruling of 2022, employers are required to systematically record their employees' working hours. With a custom solution, you not only meet legal requirements but also gain valuable data for your project management and resource planning.
“We fed three spreadsheets until nothing reconciled—a single source returned six hours per week to HR without promising new features.”

What Does a Time Tracking System Cost?
Costs depend on feature scope and number of platforms (web, iOS, Android).
- Web App (simple): €12,000 – €25,000 plus VAT – browser-based, project time tracking, reports
- With Mobile App: €25,000 – €50,000 plus VAT – iOS + Android, offline mode, push notifications
- Enterprise: €50,000+ plus VAT – GPS, ERP integration, complex work time models
Cost Example
With 50 employees at €10/user/month, you pay €6,000/year for a SaaS tool. A custom solution for €35,000 pays for itself in under 6 years – and you have full control over your data.

Ongoing license costs per employee vs. one-time development: when does custom software pay off?
Frequently Asked Questions
Does the app work offline?
Yes, times are stored locally and synchronized automatically on next internet connection. Ideal for construction sites, tunnels, or rural areas.
How accurate is the GPS tracking?
Accuracy is 5-15 meters, depending on device and environment. Completely sufficient for proof of presence to clients.
Can employees manipulate their times?
Through GPS validation, geofencing, and audit logs, manipulation attempts are made difficult and traceable. Manual corrections require approval.
