Resource plan offset rules
This topic describes the offset rules and offset order for resource plans.
Offset rules
New resource plans
New resource plans (prepaid plan2.0) can be used to offset all billable items in Simple Log Service.
A resource plan provides a fixed monthly quota during its validity period. If you use more resources than the monthly quota provides, the excess usage is charged based on the pay-as-you-go billing method.
For example, if you purchase a resource plan of 100,000 Compute Units (CUs)/month with a 3-year validity period, you receive a quota of 100,000 CUs each month for three years to offset your Simple Log Service fees.
Resource plans cannot be used to offset fees for other Alibaba Cloud products.
It resets at the beginning of each month.
Legacy resource plans
Deductions cannot be applied across different products.
A resource plan can only be used to offset fees for its corresponding billable item, not for other billable items.
A resource plan can be used to offset fees only for its corresponding billable item. For example, a Simple Log Service storage plan can be used to offset fees only for the Log Storage billable item.
Offset order
If you have both new and legacy resource plans, legacy resource plans are applied first to offset fees. Legacy plans include data transfer plans, index traffic plans, and storage plans.
If you have multiple resource plans of the same type, the plan that expires first is applied first.
