Open a new subscription with only PowerBi Pro licenses

[SandroRiz]

I want to open a new tenant for a customer, with 5 users that will use only the PowerBi Pro features.

Is it possible, or for the first admin user have I to buy at least a Microsoft 365 Business Basic license ?

Thanks

Hi, this shouldn't be an issue. There is no requirement that the administrator should have any license.
You should be able to sign-up to get started with the new tenant and licenses here
