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.

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_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.
