Resources, i.e. freelancers can be created in the Contact database as well as in the Object Manager.
As opposed to other Contact types they can be added to the Timeline View allowing them to be booked and scheduled.
They only require a license if they should be able to log into farmerswife to check their schedule. The Resource then can subscribe to their calendars, connect through the Web Client, Mobile Web Client and through the iOS app. The Web Permission Profiles defines what the Resource is allowed to do and see.
Define the Resource details in the Resource Details tab.
