That would be very useful if all members in ArcGIS Organization site are able to view how much service credits each named-user has used and his remaining and the organization's credits.
Publisher and user as default roles are currently not able to check the status for the service credit. This affects the most when users are allocated to some credits. They, of course, do know how much renaming credits they have. They will also not realize to unable to perform analysis service until they use up the credits.
A user allocated to limited number of credits should track and manage his remaining credit on their own for overall administration.
