Cost groups are used to divide budget categories into groups, such as Services, Housing costs, Projects and Service costs. A cost group needs to be specified for each budget category.

A cost group is a hierarchical element. This means it can be divided into subgroups. The maximum number of levels in the hierarchical structure is seven. Cost group structures only have to be defined once in Planon and can then be reused and linked to multiple projects.

Cost groups are not linked to a property.
