Contracted customers may have the option to move to post-paid billing. Contact our sales team to discuss your options.

​
How credits are applied

Fireworks operates on a pre-paid credits billing system. You purchase credits to use the platform:
  • Credits are used first for all usage.
  • If credits are exhausted and auto top-up is disabled, usage pauses until you add credits.
  • If auto top-up is enabled, credits are purchased automatically when your balance reaches your configured minimum.
  • You can set a monthly budget cap to limit total spend.

​
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 credit balance and auto top-up settings
Important: Usage consumes available credits. If your balance is low, enable auto top-up to avoid interruptions.

​
Why did I receive an invoice after depositing credits?

Most accounts on pre-paid billing should not see month-end overage invoices. If you received an invoice, your account may be on a post-paid contract. Contact community_billing@fireworks.ai so we can confirm your billing configuration.

​
What happens when I finish my $1 credit?

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

Account Status

Payment Method Requirements:
  • Adding a payment method is required to continue service after credit depletion
  • Add credits (or enable auto top-up) to continue service after credit depletion
  • As you spend more with Fireworks, your adaptive usage limits and serverless TPM upper bounds can 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 community_billing@fireworks.ai.
