Offline Mode

The POS is offline-first. You can continue selling even without an internet connection.

How It Works

• When the POS loads, it downloads and caches your entire product catalog locally (using IndexedDB in the browser).
• If the connection drops, an orange "Offline" banner appears at the top of the screen.
• Orders placed while offline are saved to a local queue.
• When the connection is restored, all queued orders are automatically synced to the server.
• Each offline order has a unique ID to prevent duplicates if the same order is submitted twice.

Important Notes

• Offline mode uses the last synced catalog — new products added while offline will not appear until the next sync.
• Coupon validation requires internet (coupons will not apply offline).
• Always sync before closing a session if you were selling offline.

If the offline banner will not go away, check your internet connection, then refresh the page — the POS will reconnect and sync queued orders automatically.
