What works offline, and how to read the sync status

Selling does not wait for the internet; what needs it is everything that reads from the server: reports, Dash and WhatsApp links.

Steps

1. Watch the status badge on the sell screen: green "Synced" (saved and synced with the server), grey "Waiting to sync" (saved locally), orange "Offline — saved locally", red "Storage full — sync required".
2. When the internet drops, keep selling as usual: the catalogue, prices and the branch's stock are on the device, and every sale is saved and deducted from stock at once.
3. When the connection returns, sales upload in order automatically; press nothing. The badge turns to "Synced".
4. Before closing the shift, make sure the badge is green; closing waits for sync so the drawer matches.
5. Do not clear the browser's data while you hold sales that have not uploaded, and keep free storage on the device.

What works and what does not without a connection

A return against an invoice saved on the device	Dash
Printing the receipt	The receipt link and the statement on WhatsApp
Opening a shift	Closing a shift while sales are waiting to upload

What the system does not do

It does not sync between two devices directly without the server; each device uploads to the server and then reads from it.
