To check if you are on the enhanced billing platform, see How do I know if I can access the enhanced billing platform?.
If your organization uses the enhanced billing platform, you have a fixed billing period for metered usage which runs from the first day of the month to the last day of the month. When the month ends, the usage is scheduled to be billed on your bill cycle day. Your bill cycle day is the day you created your organization. For example, if you created the account on the fifteenth of the month, you will be billed on the fifteenth of each subsequent month.
This applies to all products available through the enhanced billing platform.
If still use the previous billing platform, for more information about the billing cycle for your account, see Changing the duration of your billing cycle.
