@Scott Hauck Welcome to Microsoft Q&A forum!
Your query is more related to subscription/account management than Azure IoT related.
You should consider Azure role-based access control (Azure RBAC) which has several Azure built-in roles that you can assign to users, groups, service principals, and managed identities. Role assignments are the way you control access to Azure resources. If the built-in roles don't meet the specific needs of your organization, you can create your own Azure custom roles. For information about how to assign roles, see Steps to assign an Azure role.
Also, please refer See Azure built-in roles and Subscriptions, licenses, accounts, and tenants for Microsoft's cloud offerings.
Hope this helps. Do let us know if you have any further queries.
