Renewal Invoice: Immediate updates with proration now supported
August 12th, 2025
FastSpring now supports immediate mid-cycle subscription changes as part of renewal invoicing workflows.
You can use this workflow when subscription changes should take effect right away. For example, you might increase the quantity partway through a billing cycle or switch to a different plan immediately.
FastSpring will automatically apply prorated credit for unused time on the original plan and calculate prorated charges for the remainder of the billing period on the new plan.
