Offline Windows Billing, Barcode & Godown Inventory System
Business Situation
Multi-counter retail and wholesale merchants operating in high-footfall markets where internet connectivity fluctuates and counter speed is critical.
Operational Problem
Cloud-based billing tabs freeze whenever broadband drops, barcode scanning lags during peak hours, and loose-vs-carton stock conversions cause mismatches between the godown and counter.
What Webntric Engineered
- Keyboard-first Windows desktop POS interface engineered in C# / .NET for sub-second invoice creation without mouse dependency
- Local SQLite / MS SQL Server database architecture with automatic stock deduction across carton, box, and piece units
- Direct hardware integration with USB/serial barcode scanners, thermal receipt printers, and A4 GST invoice printing
- Party credit (udhaar) ledger with due-date tracking and automated daily encrypted backups to local drive and external USB/cloud
Expected Operational Outcome
Uninterrupted counter billing during internet outages, accurate live stock balances across godown and shop floor, and fast end-of-day cash and credit reconciliation.

Supplier invoice entry auto-calculates carton-to-piece stock and prints barcode labels.
Scan barcode -> apply retail/wholesale tier -> print thermal/GST bill in <2 seconds.
Instant party balance update + scheduled encrypted snapshot to secondary drive/cloud.
