Usage-Based Billing FAQs

When a customer changes their subscription mid-cycle—upgrading, downgrading, or switching tiers—you'll need to calculate prorated charges or credits and reflect those adjustments on the upcoming invoice.

Billing is typically triggered by project phases, time logs, or completion events and handled separately from recurring software subscriptions.

Billing platforms handle proration and billing adjustments by automatically recalculating charges when subscriptions change mid-cycle—such as during upgrades, add-ons, or plan changes.
