After your seller accepts the order, you will receive a notification and the solo cell will change to ‘Future’ state. Otherwise, it will be automatically canceled and change its status to 'Rejected.' Learn more about rejected orders.
Now just wait for the start of delivery. You can see the start date and time under the 'Info' tab of the order.
When your seller starts the delivery, Udimi will automatically filter and count all traffic. You do not need any tools for that. The order cell will change to the 'Delivery in Progress' state and start showing you detailed statistics.
If you select the 'Seller is allowed to send earlier' option on the order form, the seller can start at any time. If not, the seller starts exactly on the specified date at 12:00 UTC.
