About the company
Vaillant is a global leader in HVAC technology, offering energy-efficient systems across Europe. Their operations demanded a custom CRM-like tool to manage field activities, integrate service orders, and streamline employee workflows in real-time.
Project Overview
Vaillant partnered with Intelvision to develop a mobile-first internal service platform. The solution enabled automated workflows, CRM integration, PDF order reporting, and mobile task management. By assembling a focused delivery team, Intelvision launched a stable system within three months—eliminating manual work and improving field coordination with offline access and real-time push alerts.
Challenges and Pains
Manual Processes and Fragmented Tools
Before the new system, all service operations were handled manually, resulting in delays, inconsistencies, and a lack of centralized control across teams and tasks.
No Mobile Access
Employees couldn’t manage orders on the go. Without a mobile solution, it was difficult to update or access work-related data in real time—especially in the field.
Lack of Integration with CRM
The absence of integration with the CRM accounting system caused data silos, manual duplication of entries, and limited reporting capabilities.
No Notifications or Real-Time Updates
Without push notifications, employees missed task updates or were dependent on inefficient communication channels.
No Server Infrastructure or PDF Reporting
There was no unified backend infrastructure to connect the system components, and no ability to generate or send reports in a shareable format like PDF.
Solution
- Seamless CRM Integration
Intelvision enabled smooth data exchange between the internal system and CRM, ensuring automatic task syncing, financial data flow, and accurate reporting. - Mobile App Development with Offline Access
A cross-platform mobile solution was built using Xamarin, allowing field workers to manage tasks, receive updates, and work offline with data syncing upon reconnect.
- Automated Notifications and Workflow Management
Push notifications were implemented to alert employees in real time about new tasks, while backend automation replaced routine manual operations. - PDF Generation and Reporting
We integrated PDF generation using WkHtmlToPDF.Core, allowing employees to instantly create, view, and send work summaries to clients. - Microservices Architecture with Scalable Backend
The system was deployed on a scalable backend, with Docker and Azure DevOps CI/CD pipelines enabling maintainability, modularity, and performance.
