Task Track King
SaaS / Task & Time Management

Task Track King

Task Track King is a complete enterprise SaaS platform integrating time tracking, project and task management, automatic invoicing with Verifactu compliance, and shared client access. It enables teams to manage work time, automatically calculate revenue, and generate professional invoices directly from the application.

The Challenge

Agencies and freelancers needed an integrated solution combining accurate time tracking, complex project management, European-compliant invoicing (Verifactu), audit trails, and real-time reporting all in one platform.

The Solution

We built a robust full-stack platform with Node.js + Express, MySQL with complete audit logging, Socket.io for real-time updates, JWT authentication, integrated notification system, and automatic Verifactu-compliant invoice generation. Includes user roles, custom properties, task comments, and advanced analytics dashboards.

Business Impact

"Fully functional SaaS application with 102 centralized error handling blocks, Verifactu-compliant invoicing system, complete audit trail for all operations, support for multiple concurrent users and projects, and scalable architecture production-ready."
