Every employee that you book or assign to projects in Meisterplan counts as a resource. If you plan with roles instead of individual employees, each full-time equivalent counts as a resource (1 FTE = 1 resource). The two can also be combined as required.
Resources that are not yet or no longer working for your company can be given a corresponding entry or exit date. Only people who are active on the current date are relevant for licensing.
Resources are easy to confuse with users. With all Editions, an unlimited number of users can access Meisterplan, regardless of how many resources you plan for.
A team does not count as a resource and therefore does not affect your pricing.
