Marking units booked is how your campaign stops being a plan and starts being a record of what you have committed to. It matters for reporting, for contracts, and for anyone else looking at the campaign.
Marking Units
Open Manage → Units.
Select the units you have agreed.
Choose Mark Selected Units as Booked.
When To Do It
Mark units booked once the buy is genuinely agreed with the media owner — not when you have a hold, and not while you are still negotiating.
A hold reserves inventory temporarily. Booked means committed. Recording something as booked before it is agreed makes your campaign totals overstate what you have actually secured, which is the kind of error that surfaces at the worst moment.
What Changes
The unit's Booking Status becomes booked, and you can filter on it.
The campaign's booked totals update.
Your campaign card reflects the change.
The unit moves into the part of the process concerned with contracts, creative and installation.
Checking Your Work
Two quick reviews worth doing after a booking round:
Filter to Booked and confirm the list matches what you agreed. Nothing extra, nothing missing.
Filter to On Hold and see what is still outstanding. Those are the units still needing a decision, and their holds are still expiring.
*Note: Booking units in AdQuick records the commitment. It does not replace the contract — that is handled separately under Contracts.
