Varibill collects data from your various source systems through the help of Source Collectors. These Source Collectors are purely a reader of the configuration and provisioned products and services of the source system. Depending on how the Source Collector is developed the Source Collector may exclude inactive products or services or may include these when collecting the data.
Ensure you set the Source Collector rules to only include the data you wish to bill for.
