The Challenge / Bottleneck

Issues Faced by Metro Retail Holdings

Three retail grocery outlets suffered daily inventory mismatches between their in-store billing counters and the central warehouse. Previous legacy Windows desktop software crashed constantly and could not operate when outlet WiFi went down.

The Engineered Solution

Architecture & Strategy Delivered

We built a cross-platform web POS with React 19 that operates seamlessly in any browser. We added local IndexedDB caching so cashiers can scan and print receipts even during internet outages, syncing automatically once connectivity returns.
