See which sales are still waiting to send
While the internet is down the till keeps every sale. Here is how to see what it is holding, and when it has all gone.
While you are offline
Open Settings on the till. The sync status shows how many sales are waiting to send, so nobody has to guess.

When the line comes back
The till sends what it kept by itself. The top bar goes back to green and the sync status says everything is sent.
