Creator, Pro, Scale and Business plans have the option to enable usage-based billing. This allows you to pay for additional credits once you've used all the credits in your monthly quota.
The cost of usage-based billing depends on your tier:
- Creator: $0.30/1000 credits
- Pro: $0.24/1000 credits
- Scale: $0.18/1000 credits
- Business: $0.12/1000 credits (monthly)
Usage-based billing can be enabled from your Subscription page.
Additional credits are billed at the end of the billing cycle, and when the outstanding balance exceeds 2 times the subscription price.
If you have unused credits remaining at the end of your billing cycle, and you remain on the same subscription plan, unused credits up to twice your usual month credit quota will be automatically rolled over. You can find out more about this here: How does credit rollover work?
