These are orders currently out for delivery, on their way to the recipient.
Go to Dashboard > Workflow > Order Workflow and look for the On Route column, or Dashboard > Orders > Delivery Runsheet for the full day`s delivery list.
If you have SMS notifications set up, moving an order to On Route can automatically notify the customer their delivery is on its way, optionally including a photo of the finished arrangement.
Once delivered, mark the order as complete. If there is an issue during delivery, move it to Problem Orders instead so it is flagged for follow-up.
