Paddle's usage based billing solution makes it easy to adjust subscriptions and one-off charges for metered billing.
Dynamically change the recurring payment amounts with the Subscription Modifiers API. Increase or decrease the next payments due by a flat amount - ideal for adjusting seats and rolling credits. You can also update the whole subscription with the Subscription Update API.
Paddle manages proration for you by default - calculating the change in the amount owed between the change and their next billing cycle.
Sell add-on’s on top of a recurring subscription bill to the card and account on file with the Charges API. Charges are independent of the main subscription billing cycle and feature a separate charge and receipt.
With integrated payments (including multiple payment methods) alongside your subscriptions, Paddle makes it simple to successfully charge your customers for their metered plans.
No more lost revenue from uncharged or overdue overages.
