Local Server (Zero-Internet POS)

Run the entire CoreAxis ePOS system on one shop PC with zero internet — Tally-style.

1. Download the Local Server installer from the Download page.
2. Install on a Windows PC. The server starts automatically.
3. Connect all billing terminals (PCs, tablets) to the same Wi-Fi or LAN network.
4. Open the server's local IP address in the browser on each terminal (e.g., http://192.168.1.100:8000).
5. All billing, inventory, and accounting runs on the local network — no internet needed.
6. When internet returns, the Local Server auto-syncs all data to the cloud.

System Requirements

Supported Printers

• Thermal (Receipt): Any ESC/POS-compatible 58mm or 80mm printer — USB, Bluetooth, or network (LAN/Wi-Fi).
• A4/A5 (Invoice): Any standard printer supported by the OS — laser or inkjet.
• Barcode Label: TSC, Zebra, or any ZPL-compatible label printer.

Network Requirements

• Cloud Mode: Minimum 2 Mbps internet. 10 Mbps+ recommended for multi-user / multi-branch setups.
• Local Server Mode: No internet required for billing. LAN or Wi-Fi network between PC terminals. Internet needed only for cloud sync, e-invoicing, and SMS/WhatsApp.
• Mobile App: Works fully offline. Internet needed only for initial sync and periodic data sync.

Offline Mode

CoreAxis is designed to work even when your internet drops.

How it works

• Mobile App: All data is cached in a local SQLite database. On first login, a full data sync downloads products, customers, suppliers, and settings. After that, the app reads from SQLite first and syncs in the background.
• Web App: Uses IndexedDB for offline caching. Sales created offline are queued and sync when the connection returns.
• Local Server: Runs everything locally — no internet dependency at all.

• Creating sales (POS billing)
• Viewing products, customers, and inventory
