Pay-per-Use to Yearly/Monthly

If you have a pay-per-use ECS that you expect to use for a long time, you can change it to yearly/monthly billing to reduce costs. Doing so will create an order. After you pay for the order, yearly/monthly billing will be applied immediately.

Suppose a user bought a pay-per-use ECS at 15:29:16 on April 18, 2023 and changed it to yearly/monthly billing at 16:30:30 on the same day. After the user paid for the order, yearly/monthly billing was applied immediately. On the Billing Center > Billing page, three line items were generated:

Pay-per-use expenditures for 15:29:16 to 16:00:00 on April 18, 2023
Pay-per-use expenditures for 16:00:00 to 16:30:30 April 18, 2023
A single, yearly/monthly expenditure generated April 18, 2023, 16:30:30
