Sigma allows you to have multiple Billing Groups. A Billing Group is a group of Tenant Accounts that you want to bill at the same time which share a common set of attributes that should be applied to the bills that are generated.

A Tenant Account must be in a Billing Group to allow billing and can only be assigned to one Billing Group at a time.
