Bills

You can view the resource usage and bills for different billing cycles on the Bills page in the Billing Center.

Bill Generation

After yearly/monthly resources are paid, a bill is reported to the billing system for settlement.

The usage of pay-per-use resources is reported to the billing system at a fixed interval. Pay-per-use resources can be settled by hour, day, or month based on usage type. Pay-per-use IoTDA resources are settled by day.

The fee deduction time of pay-per-use resources may be later than the settlement period. For example, if an IoTDA instance (settled by hour) is deleted at 08:30, the fees generated during 08:00 to 09:00 are usually deducted at about 10:00. On the Billing Center > Billing > Transactions and Detailed Bills > Transaction Bills page, Expenditure Time indicates the time when a pay-per-use product is used.

Viewing Bills of a Specific Resource

[Example 1 (IoTDA): Use the resource ID to search for the bill. The resource ID is the same as that in the bill.]

Log in to the management console, choose IoT > IoTDA Device Access in the navigation pane.
The IoTDA instance list page is displayed. Go to the details page of the target instance.
Click the icon shown in the following figure to copy the resource ID.

Figure 1 Obtaining the resource ID
On the top menu bar, choose Billing & Costs > Bills.
The Bills page is displayed.
Choose Transactions and Detailed Bills > Bill Details. On the displayed page, select Resource ID as the filter condition, paste the resource ID copied in 2, and click to search for the bill of the resource.

By default, bill details are displayed by usage and billing cycle. You can also select other statistical dimensions or periods.

Check the Consistency of the Actual Usage and Billed Usage

Assume that you purchased four IoTDA SU1 units at 10:09:06 on April 8, 2023, and delete the them at 12:09:06 on April 10, 2023.

IoTDA transaction bills

Pay-per-use IoTDA instances are billed by hour and are settled on the hour. You can check whether the information about each billing period in the transaction bill is consistent with the actual information. For details, see Table 1.

**Table 1** IoTDA transaction bills
Service	IoTDA
Product	IoTDA standard instance
Billing Mode	Pay-per-use billing
Expenditure Time	From 10:09:06 on April 8, 2023 to 12:09:06 on April 10, 2023, 2 transaction bills were generated: April 8, 2023, 00:00:00 to April 9, 2023, 00:00:00 April 9, 2023, 00:00:00 to April 10, 2023, 00:00:00
List Price	List price = Usage x Unit price In this example, there are two billing cycles. For example, if the price is USD0.81 per SU1 unit per day, the list price is USD3.24 (0.81 x 2 x 2).
Discounted Amount	Discounts offered for cloud services, for example, commercial discounts, partner authorized discounts, and promotional discounts. Discounts are based on the list prices.
Truncated Amount	Huawei Cloud bills a resource with the price (CNY) accurate to the eighth decimal place. However, the amount due is truncated to the 2nd decimal place, while the third and later decimal places are referred to as the truncated amount.
Amount Due	Amount due = List price – Discount amount – Truncated amount

IoTDA bill details

Bill details can display in multiple ways. By default, the bill details of a resource are displayed by usage and by billing cycle. Table 2 illustrates the IoTDA bill details, which can be used to check against the actual usage.

**Table 2** IoTDA bill details
Service	IoTDA
Product	IoTDA standard instance
Billing Mode	Pay-per-use billing
Resource Name/ID	Name and ID of an IoTDA instance. Example: iotda-test-instance, 4cdeb1cd-7071-4890-9ce4-e6c2299e960e
Specifications	Specific EVS disk type and capacity. Example: IoTDA standard instance \| Small package SU1 \| 2
Usage type	Duration
Unit Price	In the pay-per-use billing mode, the unit price is provided only when the amount is equal to the usage multiplied by the unit price. No unit price is provided in other pricing modes, for example, tiered pricing. For details about the unit price of pay-per-use IoTDA instances, see IoTDA Pricing Details.
Price Unit	Unit price in IoTDA Pricing Details: USD/set.
Usage	The usage is displayed by the unit price, which is CNY/hour for IoTDA. The usage is measured by hour. In this example, the total usage is 2 days.
Usage Unit	day
List Price	List price on the official website = Usage x Unit price x Capacity In this example, the usage is 2 days, and the unit price can be queried in IoTDA Price Details. For example, if the price is USD0.81 per SU1 unit per day, the list price is USD3.24 (0.81 x 2 x 2).
Discounted Amount	Discounts offered for cloud services, for example, commercial discounts, partner authorized discounts, and promotional discounts. Discounts are based on the list prices.
