At HostArmad, your invoices will always use your primary profile information as billing information.
You can create separate sub-accounts and allow them certain permissions to operate within your client area. Details related to the sub-accounts cannot be included or used as billing information.
If you want to learn more about the actions sub-accounts will allow you to perform, you can refer to this article:
