With Bill Analyst you can organize accounts into categories by creating account groups. This is helpful when you have a lot of accounts. Account groups are much like file folders. With them, you can organize your accounts into categories to make viewing and ordering statements much easier. Account groups are shared among all the users of your organization. When you're running summary or detail reports, you can use hierarchies/levels to get a similar result.
The group name is listed on the left side and the number of accounts is show in parenthesis after it.
