Charges are indicated by positive numbers, and refunds, including refunds for downgrading, are indicated by negative numbers. For some products or projects, your refund amount during a billing period may be more than the amount of charges, hence the negative bill.
Billing data allows eight decimal places, but the actual amount you are charged (deduction) is rounded to two decimal places. As a result, there may be a difference between the higher-precision billing amount and the lower-precision deduction. The system calculates the difference, for which there are two cases:
Case 1: Positive difference
If the higher-precision billing amount (a) is smaller than the lower-precision deduction (b), it indicates that you were overcharged by the amount of b minus a, in which case you can submit a ticket for compensation.
Case 2: Negative difference
If the higher-precision billing amount (a) is greater than the lower-precision deduction (b), it indicates that you were undercharged by the amount of a minus b. If this occurs, we will not request that you pay the undercharged amount.
CDN tags are bound to domains, but the product is billed at the account level, so you cannot view CDN costs by tag in bills.
COS tags are bound to buckets, but the product is billed at the account level, so you cannot view COS costs by tag in bills.
To view the costs of IDC bandwidth packages, CDN, or COS by tag, please download bill details.
IDC bandwidth packages, CDN, and COS do not support project-specific billing. Their costs are collectively treated as those of the default project in bills.
The tags of live streaming products are bound to domains, but the products are billed at the application level, so you cannot view their costs by tag in bills.
Tagging takes effect immediately, but bill data is updated only once every 24 hours, so you may not see your tags immediately.
If you can’t find a billed instance in the corresponding console page, it’s probably because the instance was returned or it was terminated after it expired.
Each instance in the bill has a transaction ID. If an instance is prepaid, it also has an order ID. You can go to the Order Management page to view the purchase time, purchaser, purchased duration, and start/end time of an instance.
CVM and CBS are independent products. There are two cases for their presentation in bills:
In your bill, the two will be presented as separate instances and will not be associated with each other.
If you assign an instance to a new project, the costs of the instance that are incurred after the change will belong to the new project.
In other words, the costs of an instance are billed under whichever project the instance belongs to at the time of cost deduction.
Data in Bill Overview and Bill by Instance is cached and is refreshed every 24 hours. You can view real-time billing data in Bill Details.
Bills can display the instance names of only some products. For products whose instance names are not displayed in bills, you can use instance IDs to distinguish one from another. For more information, go the corresponding product page in the console or view the documentation of the product.
