Once you are happy with your planner and everything is aligned to your budget and objectives, next step would be to sign off on placements you want.
You can either sign off on specific selected placements at the publisher level or just select everything at once by clicking on the 'Sign off All Items' button - located top right.
The next step will be to provide a comment under each publisher (or apply comment to all) and once applied the 'sign off' button will become active to select.
After you select the button there will be a prompt to enter in your password - this is your digital signature to confirm you are signing off on these placements.
Once confirmed this will then trigger the email notifications to your nominated publishers requesting them to login and review the plan for further changes or approval.
