Lucrum WeighBridge
Offline-first weighbridge system with ERP & machine integration.
Project Overview
Lucrum WeighBridge is a Windows-based industrial-grade application designed to capture real-time truck weight data from weighbridge machines, log it securely, and sync with ERP systems. It supports offline-first workflows, CCTV camera feeds, and full audit trails, ensuring operational continuity and data accuracy at loading/unloading stations.
