 # Billing service for Extended Security Updates for Windows Server 2012 enabled by Azure Arc
 
-Billing for Extended Security Updates (ESUs) is impacted by three factors:
+Three factors impact billing for Extended Security Updates (ESUs):
 
-- The number of cores you've provisioned
+- The number of cores provisioned
 - The edition of the license (Standard vs. Datacenter)
 - The application of any eligible discounts
 
-Billing is monthly. Decrementing, deactivating, or deleting a license will result in charges for up to five more calendar days from the time of decrement, deactivation, or deletion. Reduction in billing isn't immediate. This is an Azure-billed service and can be used to decrement a customer's Microsoft Azure Consumption Commitment (MACC) and be eligible for Azure Consumption Discount (ACD).

 > [!NOTE]
 > 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.
 
 ## Back-billing for ESUs enabled by Azure Arc
 
-Licenses that are provisioned after the End of Support (EOS) date of October 10, 2023 are charged a back bill for the time elapsed since the EOS date. For example, an ESU license provisioned in December 2023 will be back-billed for October and November upon provisioning. Enrolling late in WS2012 ESUs makes you eligible for all the critical security patches up to that point. The back-billing charge reflects the value of these critical security patches.

-If you deactivate and then later reactivate a license, you'll be billed for the window during which the license was deactivated. It isn't possible to evade charges by deactivating a license before a critical security patch and reactivating it shortly before.

 > [!NOTE]
 > 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.
