Legacy ERP Modernization for Cortex Manufacturing
Modernizing a fragile, decade-old ERP into an API-driven platform with intelligent automation — without a risky big-bang rewrite.
- Month-end close
- 4 days → 6 hrs
- Manual data entry cut
- 55%
- Integration uptime
- 99.9%
The challenge
Cortex ran a decade-old ERP that everyone was afraid to touch. Finance, inventory and shop-floor systems didn't talk to each other, so month-end close took four days of manual reconciliation across spreadsheets.
What we built
Rather than a risky full replacement, we modernized incrementally. We wrapped the legacy core in a clean API layer, integrated the disconnected systems through a message bus, and added intelligent automation for routing and reconciliation.
- API facade over the legacy ERP to enable safe integration
- Event-driven integration across finance, inventory and operations
- Intelligent automation for invoice matching and anomaly detection
- Real-time dashboards replacing manual spreadsheet reports
The outcome
Month-end close dropped from four days to six hours. Manual data entry fell 55%, and finance gained real-time visibility for the first time — all without the downtime of a big-bang migration.
