This topic describes the rules that determine how resource plans are used to offset resource fees and the order based on which resource plans are used to offset resource fees.

Offset rules

  • Object Storage Service (OSS) resource plans can be used only to offset resource fees of OSS.
  • Resource plans of a specific type can be used to offset resource fees only for billable items subject to the resource plans.
  • Regional resource plans can be used to offset resource fees only in specific regions. For example, resource plans of the China (Qingdao) region can be used to offset resource fees that are generated only in the China (Qingdao) region.
  • If the resource plan expires or the actual resource usage exceeds the quota of the resource plan, the pay-as-you-go billing method is automatically used.

Offset order

You can purchase multiple resource plans of the same specific types. If you purchase multiple resource plans of the same type, the resource plan with the earliest expiration time is applied first.
