Bills

Bill Generation

Transaction records for yearly/monthly subscriptions are generated immediately after being paid for.

The usage of pay-per-use resources is reported to the billing system at a fixed interval. A pay-per-use resource is billed by the hour, day, or month, depending on the resource's usage type. The GeminiDB Cassandra instance usage is billed by the hour. For details, see Bill Run for Pay-per-Use Resources.

You are not charged immediately after a record is generated. For example, if a pay-per-use GeminiDB Cassandra instance (which is billed on an hourly basis) is deleted at 08:30, you will still have expenditures for the 08:00 to 09:00 hour. However, you will not likely be billed for the 08:00 to 09:00 hour until about 10:00. On the Bills page of the Billing Center, select the Bill Details tab. Expenditure Time in the bill indicates the time when the pay-per-use resource is used.

Scenario Example: Checking the Consistency of the Actual Usage and Billed Usage

Assume that you purchased a pay-per-use GeminiDB Cassandra instance at 10:09:06 on April 8, 2023 and deleted it later that day, at 12:09:06.

• Transaction Records

  Pay-per-use GeminiDB Cassandra instance usage is calculated by the second and but billed on an hourly basis. You can check the transaction records against the actual usage. The billed resources are billed separately. For details, see Table 1.

  Table 1 GeminiDB Cassandra transaction records

  Service Type	GeminiDB Cassandra
  Resource Type	GeminiDB Cassandra storage
  Billing Mode	Pay-per-use
  Expenditure Time	For the period of time from 10:09:06 to 12:09:06 on April 08, 2023, 6 transaction records would be generated for the resource usage in the following periods: 2023/04/08 10:09:06 - 2023/04/08 11:00:00 2023/04/08 11:00:00 - 2023/04/08 12:00:00 2023/04/08 12:00:00 - 2023/04/08 12:09:06
  List Price	List price on the official website = Usage x Unit price x Capacity The GeminiDB Cassandra instance was used for 3,054 seconds in the first period, and the unit price can be obtained on the Pricing Details page. The list price for the first period = (3054 ÷ 3600) × 0.0007 × 40 = $0.02375333 USD. Similarly, you can calculate the GeminiDB Cassandra instance list price for the other periods.
  Discounted Amount	Discounts offered for cloud services, for example, commercial discounts, partner authorized discounts, and promotional discounts. It is the discounted amount based on the list price.
  Truncated Amount	Billing of Huawei Cloud is calculated to the 8th decimal place. However, the amount due is truncated to the 2nd decimal place. The third and later decimal places are referred to as the truncated amounts. Take the first period as an example. The truncated amount is $0.00375333 USD.
  Amount Due	Amount due = List price – Discount amount – Truncated amount Take the first period as an example. If the discount amount is 0, the amount due is $0.02 USD (0.02375333 – 0 – 0.00375333).
