Plans, add-ons, and all monetized entitlement types (pay-as-you-go, pay-in-advance, overages, tiered pricing, credit costs, and credit bundles) now support quarterly pricing. Quarterly follows the same patterns as yearly: if a plan has a quarterly period, quarterly prices must be defined for base charges and for any monetized entitlements.

Display priority across the UI and checkout components is Monthly > Quarterly > Annually. Entitlement reset periods are unchanged. Entitlements on quarterly plans still reset on their existing daily, weekly, or monthly cadence.
