The Challenge
A Belgian precision manufacturing company with €45M annual revenue was running critical operations on a 15-year-old custom ERP system. The original developers had left years ago, documentation was sparse, and the Visual Basic codebase was nearly impossible to modify. New customer requirements for real-time inventory visibility and EDI integration were impossible to implement. The system had become a competitive liability.
Our Solution
We applied the strangler fig pattern to incrementally modernize without disrupting operations. New capabilities were built as microservices with a clean API layer, while we systematically extracted and replaced legacy modules. We prioritized the most painful areas first: inventory management, order processing, and supplier integration. The team received hands-on training throughout.
Results Achieved
- 73% of legacy codebase modernized over 18 months
- New features now ship in days instead of months
- Successfully integrated with 4 major customer EDI systems
- Real-time inventory accuracy improved from 84% to 99.2%
- Zero production downtime during entire modernization
- Internal team now maintains and extends the new system independently
Technologies Used
“We were terrified of touching our ERP - one wrong change and production stops. Cloudrix's incremental approach let us modernize without betting the company. Eighteen months later, our system is an asset instead of a liability. Our team learned modern practices alongside the rebuild, so we're self-sufficient now.”
