• Match usage: If your bill shows an hourly storage capacity of 40 GB, you can purchase a 40 GB Standard ZRS storage plan to precisely cover your actual usage.

You can purchase a resource plan that corresponds to the billable items identified by the in your bill.

   Important

   • After you purchase a resource plan, you cannot change its type. A resource plan of a specific type can offset only the fees of its corresponding billable items. When you purchase a resource plan, make sure to select a suitable resource plan type.

   • A resource plan takes effect immediately after purchase. The fees for the associated billable items are then automatically offset by the resource plan.

5. Follow the on-screen instructions to complete the purchase.

What do I do if I purchase the wrong resource plan?

If you purchase a resource plan that does not meet your requirements, you can select a solution based on whether the plan has been used and the number of days since its purchase.

• For an unused OSS resource plan within five days of purchase:

  You can request a full refund. After the refund is processed, you can purchase the correct resource plan.

• For a resource plan that has been used within five days of purchase, or for any plan that is more than five days old:

  You can select a solution based on the deduction method of the resource plan.

  Deduction method	Resource plan	Solution	Description
  Fixed total amount	Standard LRS storage plan IA LRS storage plan	Request a partial refund.	Refund amount = Paid amount - (Original price / Purchase duration in days) × Used days
  		If you do not want to request a partial refund, you can change the redundancy type of the bucket from LRS to ZRS. Then, you can use a ZRS storage plan to deduct the corresponding storage capacity.	After the redundancy type is changed, the bucket is charged based on the ZRS price, which is higher than the LRS price. For more information about pricing, see OSS Pricing.
  	Anti-DDoS Basic plan	Request a partial refund.	Refund amount = Paid amount - (Original price / Purchase duration in days) × Used days
  Decreasing total amount	Transfer acceleration plan	Request a partial refund.	Refund amount = Paid amount - (Original price / Purchase duration in days) × Used days
  Monthly subscription	Outbound data transfer plan	Refunds are not supported	Refunds are not supported

For more information about how to request a full or partial refund, see Refund resource plans.

What do I do if a resource plan of the desired capacity is not available on the buy page?

The OSS resource plan buy page typically offers plans with capacities such as 100 GB, 500 GB, 1 TB, and 10 TB. If a plan with your desired capacity, such as 9 TB, is not available, your purchase method depends on whether the resource plan type supports stacking.

• For resource plans that support stacking

  For resource plans that support stacking, such as outbound data transfer plans, you can purchase multiple plans to reach the desired capacity. For example, to obtain 9 TB, you can purchase one 5 TB plan and two 2 TB plans.

• For resource plans that do not support stacking

  For resource plans that do not support stacking, such as Standard LRS storage plans, you can use one of the following methods:

  • Purchase a 10 TB Standard LRS storage plan.

  • Purchase a 5 TB Standard LRS storage plan. The excess usage is billed on a pay-as-you-go basis.

For more information about which resource plans support stacking, see Supported operations.
