The Challenge
An IT service partner of Deutsche Telekom used Lexware as their order and quotation system, but Telekom required every quotation to reach its systems in a specific format — D!VE XML, the data model behind Telekom’s digital procurement platform for third-party suppliers and pre-vendors. Lexware had no native way to produce D!VE-compliant XML, so quotations created in Lexware could not be submitted directly into Telekom’s partner interface without a manual reformatting step — and manual conversion at this stage introduces exactly the kind of transcription errors that a rigid, machine-validated XML format has no tolerance for.
What We Built
A native .NET WinForms desktop application that bridges Lexware and Deutsche Telekom’s D!VE platform, converting order and quotation data from Lexware’s format directly into valid D!VE XML. The app reads the source Lexware data, maps it into the D!VE data model, and produces submission-ready XML that the partner interface accepts without further editing — closing the gap between the partner’s existing order system and Telekom’s own procurement platform. As the Full Application Lifecycle Management partner, exbisoft owned the tool end to end, from initial design through ongoing maintenance as Telekom’s D!VE format evolved.
What It Delivers
- Automated, direct conversion from Lexware order and quotation data to Telekom’s D!VE XML format
- Eliminates manual reformatting and the transcription errors it introduces
- Windows desktop tool fitting directly into the partner’s existing Lexware-based workflow
- Full Application Lifecycle Management — design, development, and ongoing maintenance owned by exbisoft as Telekom’s D!VE format evolved
