 ### Managing committers and repositories
 
-{% data variables.product.prodname_GH_advanced_security %} is billed per committer and enabled by repository. If a committer is removed from an organization or enterprise, they are no longer billable as of the removal day. However, if you disable {% data variables.product.prodname_GH_advanced_security %} on a repository, the committers tied to that repository will remain billable until the end of the current monthly billing cycle.
