I created an Azure AI Foundry managed compute deployment for learning purposes, which resulted in unexpected charges.

The deployment was successfully deleted on 11 October 2026 at 11:13 PM IST. I also deleted the associated Foundry resource and resource group.

Current situation

Subscription status: Disabled

Azure Portal displays a message confirming that the subscription is cancelled and that a final invoice will be issued for charges incurred before cancellation.

No resource groups or resources remain in the subscription.

• Cost Analysis shows October actual usage of X amount (pre-tax).

No additional actual costs have appeared after 11 October.

As of 9 November 2026, Billing → Invoices still shows zero invoices.

The previously displayed expected invoice availability date was 9 November 2026.

Azure is also not allowing me to detach my payment method.

Questions

Does Disabled status mean the subscription is already cancelled, or is any additional cancellation action required?

Will Azure automatically generate the final invoice for the October usage?

Can a Disabled subscription prevent or delay final invoice generation?

Should I reactivate the subscription and cancel it again, or leave it Disabled?

Is it safe to delete the subscription before the final invoice is generated?

When should I expect the final invoice, and when can I remove my payment method?

I do not want to reactivate the subscription or incur any further charges. I only want to ensure that the existing usage is billed correctly and the subscription is properly closed.

Any guidance based on Microsoft's billing process or similar experience would be appreciated.
