Hi Thomas, do you have any plans to implement tenant management soon? I’m trying to decide whether I should continue building my own solution for now or hold off and wait for your implementation.
Also, thanks again for the system so far ; I’ve just implemented my replacement of Stripe with PayFast, and I’ve been loving the AI configs. Really excited to see what comes next!

I will probably do a tenant overview in the back-office soon'ish. But the backup and deletion is not just around the corner.

I have a branch where I move the back-office to a different domain both on localhost and in the cloud, see this pull request.

When done I plan to change how you sign into the BackOffice, so you use your Microsoft EntraID account (from the same EntraID that your Azure infrastructure is hosted on). That is, the BackOffice will have a completely different domain and authentication than the app itself. I hope to get this done this week.

As part of this I'm also deleting the BackOffice self-contained system, as I learned that it operates on the same data as Account.

That makes a lot of sense, separating the BackOffice into its own domain with Entra ID auth feels like a really solid direction, especially from a security and operational standpoint.

I also agree with removing it as a self-contained system if it’s essentially operating on the same Account data. Treating it more as an internal admin surface over existing domains seems much cleaner.

I’ll hold off on building my own tenant overview for now as I’d rather align with your approach and focus on planning my SaaS roadmap until the first version of the app is out.

Looking forward to seeing how you implement the Entra ID flow and domain separation. Thanks for the update!

@xd-Park3rr The Back Office just landed (see animaked gif on frontpage of readme). It has some tenant managment (read-only). Backcup, recovery is still pending.
