Insertion order
From DigitalJargonBuster
A formal contractual order to book an advertising campaign.
These printed order forms have been used in campaign management for all advertising media. Typically, the insertion order identifies the campaign name, the media (website) receiving the order and the planner or buyer giving the order, the individual ads to be run (or who will provide them), the ad sizes, the campaign beginning and end dates, the buying model (such as CPM), the total cost, discounts to be applied, and reporting requirements and possible penalties or stipulations relative to the failure to deliver the agreed volume of advertising.
