Cost Amortization Methods

The following cost amortization methods are supported:

Enterprise Projects and Tags for Amortized Costs

Yearly/Monthly Subscriptions

  • Enterprise project: By default, the enterprise project selected for the order is used for amortized costs of your yearly/monthly subscription.
  • Tags: Starting from June 01, 2021, the resource tags used when the amortized costs are calculated are applied to the daily amortized costs of your yearly/monthly subscriptions. Tags for costs amortized before June 01, 2021 do not change even if the tags for their resources change.

Pay-per-Use Resources

The enterprise project and cost tags used when pay-per-use resources are settled are used for your amortized costs.
