Capped billing

Your hold is twice the estimated cost, including our fee. Pay the provider’s actual cost plus the fee, capped at that hold. Unused funds return to your balance.

Billing can finish after the image arrives. Check Activity or before retrying an uncertain request. Keep automatic retries disabled.
