Licences are neither co-term, nor PDL, in themselves; a license can be added to either type of Organization.
Typically, for rollouts into co-term Orgs, which happen over a period of time, any delays between order and usage can be accounted for within the solution pricing; that's why it's important to plan migrations effectively and communicate these with the Cisco Meraki team, prior to placing orders. Remember that Meraki Zero Touch Provisioning, maybe coupled with Templates or API-based automation, can also make your rollouts extremely rapid!
