Billing rules control how charges are calculated for a service — when invoices are generated, how partial periods (pro-rata) are priced, and how billing periods align to calendar boundaries.

DATE_TO_DATE billing generates invoices for a fixed period from the service creation date — each period runs from creation anniversary to anniversary (minus one day where applicable).

FIXED_CALENDAR_MONTH aligns the first invoice to calendar period boundaries from the start of the creation month or year — without a separate daily pro-rata for partial days in the creation month.

FIXED_PRORATA aligns billing periods to calendar boundaries and splits partial periods into daily pro-rata (creation date → end of month) plus remaining full month(s) within the cycle.

UNFIXED_CALENDAR_MONTH combines a calendar-month pro-rata for the creation month with a rolling full-cycle invoice starting the 1st of the next month.

UNFIXED_PRORATA is mostly applicable to quarterly, semi-annual, and yearly billing cycles. Unlike FIXED_PRORATA, the next invoice period starts from the month after creation — not aligned to calendar quarters.
