⚠️

The Operational Challenge

Processing over 2,500 daily customer walk-ins across 8 checkout lanes, the supermarket was losing revenue and customer goodwill to long queues during peak weekend rush hours:

  • Laggy Browser-Based POS Latency: The previous web-based POS experienced 2-4 second delays per barcode scan when multiple cashiers were billing simultaneously.
  • Manual Weighing Discrepancies: Cashiers manually typed weights from fruits and vegetable scales, causing pricing errors, inventory leakages, and line slowdowns.
  • Peak-Hour System Freezes: Whenever local broadband dipped, the cloud terminals spun loading wheels, causing frustrated shoppers to abandon full shopping carts.
  • Barcode Sticker Compatibility: Inability to quickly print customized barcode price tags for packaged staples, dry fruits, and bakery goods.
✅

The InventoryPlus Solution

InventoryPlus implemented a high-performance local network counter architecture with direct POS hardware connectivity:

  • WPF Native Client Engine: Sub-10ms barcode lookups utilizing hardware-accelerated WPF UI and localized multi-counter LAN database routing.
  • Direct Electronic Weighing Scale Plugin: Connected weighing scales via RS232/USB. The moment produce touches the pan, net weight and calculated price populate the bill automatically.
  • Weight-Embedded EAN Barcodes: Enabled in-store pre-packing scale barcode scanning (EAN-13 price/weight barcode parsing) for the bakery and butchery sections.
  • Multi-Counter Smart LAN Mode: All 8 checkout counters sync continuously to the local in-store manager terminal, operating 100% offline from the internet.
