We've added powerful support to modify ongoing subscriptions in Orb by introducing the ability to add, remove, or edit individual prices on a subscription. This allows you to model complex billing behaviors like optional add-on prices while maintaining total control over billing and invoicing. Additionally, you can now add or change prices on a subscription without the need for a heavyweight plan change or disruptions to normal invoicing behavior.

Whether changes are backdated to the past or scheduled for the future, Orb will ensure correctness, modifying and issuing new invoices to ensure your customers are billed properly. See our docs for more details on use cases and behavior. And to visualize changes to a subscription's prices over time prices over time, you can use the new subscription timeline view.
