## Bill Introduction
- **Transaction Bill**: It reflects the deduction status of your monthly resource usage. The monthly billing date is the 1st day of the next month. If the order creation time of post-paid resources is in the next month, it will be recorded in the account in the next month.
- **Billing Period**: Refers to the time when paid orders are divided and recorded into the account. For example, a billing period of January 2018 reflects the transaction bill where the "creation time" of the order is between 00:00 on January 1, 2018 and 00:00 on February 1, 2018.
- **Pending Entry**: All historical unpaid orders are pending entry orders. After payment is completed, they will be recorded into the account according to the billing period of the payment time.
