Offline-Capable POS System & Billing Software Sri Lanka

Continuous billing even when your internet connection goes down. Built with a robust hybrid architecture.

ශ්‍රී ලංකාවේ ව්‍යාපාර සඳහා විශ්වාසනීය පොස් සිස්ටම් (POS System), බිල්ලින් මෘදුකාංගය (Billing Software), සහ ස්ටොක් කළමනාකරණ මෘදුකාංගය (Stock Management Software).

How Offline Billing Hybrid Architecture Works

Unlike standard web-only billing tools that lock up during internet outages, Pencil Codes POS combines a high-speed PHP / MySQL Cloud Backend with an embedded Electron / SQLite Local Database Sync Queue.

  • Instant Local Checkout: Bills print instantly on thermal printers without waiting for network latency.
  • Zero-Downtime Fallback: If WiFi drops, billing switches to SQLite seamlessly.
  • Automated Sync Queue: Restores transaction logs to cloud servers automatically when connection returns.
