The POS terminal continues working without internet. Sales are queued locally and synced automatically when connectivity returns.

How It Works

1. While online, products and categories are cached to your browser (30-minute TTL)
2. When internet drops, a red offline banner appears at the top
3. You can continue adding products and processing sales normally
4. Each sale is saved locally with an OFFLINE-XXXXX receipt number
5. When internet returns, queued sales sync automatically — an amber banner shows progress
6. Real sale numbers replace the offline placeholders after sync

Limitations

• Customer search requires internet (cached customers are not available offline)
• Loyalty points are not updated until sync completes
• If your session expires while offline, queued sales may fail to sync — reopen a session first
• Product data older than 30 minutes may be stale
