How credits are applied

Fireworks operates with a postpaid billing system:
  • Prepaid credits are used first for all usage
  • Once credits are exhausted, you continue to accrue charges for additional usage
  • Usage charges are billed at the end of each month
  • Prepaid credits are instantly applied to any outstanding balance
Example: If you had a $750 outstanding bill and added $500 in credits, your bill would reduce to $250, with $0 remaining credits available for new usage.

​
Missing credits after purchase?

If you don’t see your credits reflected immediately:
  1. Visit your billing dashboard
  2. Review the “Credits” section
  3. Check your current outstanding balance
Important: Credits are always applied to any existing balance before being available for new usage. If you had an outstanding balance, your credits were automatically applied to reduce it.

​
Why did I receive an invoice after depositing credits?

You’ll receive an invoice for any usage that exceeded your pre-purchased credits. This process happens automatically, regardless of subscription status. Example: If you deposited $20 in credits but incurred $83 in usage, you’ll be billed for the $63 difference at month-end.

​
What happens when I finish my $1 credit?

When you finish your $1 credit, the following occurs:

​
Account Status

  • Without payment method: Your account will be suspended until you add a payment method. Additionally, accounts without a payment method are subject to a provisional rate limit of 10 requests per minute (RPM). To access full rate limits (up to 6,000 RPM), add a payment method in your billing settings.
  • With payment method: You can continue using the service with full rate limits and usage-based billing
Payment Method Requirements:
  • Adding a payment method is required to continue service after credit depletion
  • You’re billed at the end of the month for actual usage
  • You can incur bills up to your configured spend limit (default: $50/month for new accounts)
  • As you spend more with Fireworks, your allowed usage limits increase

​
Where’s my receipt for purchased credits?

Receipts for purchased credits are sent via Stripe upon purchase. Check your email for receipts from Stripe (not Fireworks). If you can’t find your receipt, contact [email protected].
