Back-billing for ESUs enabled by Azure Arc

Question

Hi

We have had an ESU license from EOS October 10, 2023.

Originally we had 400 total virtual cores, but we no longer needed as many so wanted to reduce the total virtual cores to 208, unfortunately it was reduced to 108 by mistake.

If we try to increase the virtual cores to the required amount, 208, it is showing back billing all the way back to EOS October 10, 2023 of over £9,500!

Will we really need to pay this or will it re-calculate the back-billing based on just the missing month as we have already paid for those earlier months?

Thanks

Hi @Billy

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

Licenses or additional cores provisioned after End of Support are subject to a one-time back-billing charge during the month in which the license was provisioned. This isn't reflective of the recurring monthly bill.

The back-billing cost appears as a separate line item in invoicing. If you acquired a discount for your core WS2012 ESUs enabled by Azure Arc, the same discount may or may not apply to back-billing. You should verify that the same discounting, if applicable, has been applied to back-billing charges as well.

Note that estimates in the Azure Cost Management forecast may not accurately project monthly costs. Due to the episodic nature of back-billing charges, the projection of monthly costs may appear as overestimated during initial months.
