Use Period Thresholds for Proration
This feature extends the range of options available to bill the first and last partial bill periods. Until this feature, the First and Last partial periods were always prorated. Now, you can do the following:
- Bill the partial period in full i.e. the charge amount applicable for a full charge period
- Not bill the partial period i.e. 0 is billed.
- Not bill if the partial period is less than specified threshold. Two threshold types are Days and Charge Period Fraction.
The Subscription profile shows a new section titled Partial Period Billing and Credit Rules.
A new section Partial Period Billing and Credit Rules is also shown in the Product summary page.

The first partial period is not billed because 22 days is less than 0.9 charge period fraction i.e. 0.9 *30= 27 days.
The last partial period is billed the complete charge amount as the number of days i.e. 6 is more than 5 days.
- Predictable, dispute-resistant billing: customers are charged only for whole months, reducing confusion about partial-period charges.
- Consistent price presentation: stable monthly amount (e.g., $5.99) across full months avoids proration calculations and rounding issues.
