Working without a connection

Capture now, send later - nothing is lost and nothing is sent twice.

Steps

Open Log a visit and New sales order once with a connection (or the phone home): your customers and items are kept on the phone.
With no connection, Navigate shows “You are offline” and saves what you capture on the phone - Waiting to be sent lists it.
When the connection returns it is sent by itself (also when you next open Navigate). Tap Send now to send at once.
Anything not accepted stays on the phone with the reason (e.g. “an item is no longer sold”, “your role may not create sales orders”) - capture it again correctly and Remove the old one.

Each visit or order carries its own number from the phone: if it is sent twice (a weak connection, a second tab), Navigate records it once. Signed out with items still waiting? They wait for you - they are sent when you sign in again on that phone, never under someone else.
