Invoice questions

Q: Why did I receive an invoice when I only deposited credits?

Fireworks.ai billing works as follows:

  • Deposited credits are used first.

  • Once credits are exhausted, you continue to accrue charges for additional usage.

  • Usage charges are billed at the end of each month.

  • You’ll receive an invoice for any usage that exceeded your pre-purchased credits.

This process happens automatically, regardless of subscription status. To prevent additional charges, please monitor your usage or contact support to set up spending restrictions.

Q: Where’s my receipt for purchased credits?

Receipts for purchased credits are sent via Stripe upon initial credit purchase. Check your email for receipts from Stripe (not Fireworks). Contact billing@fireworks.ai if you still are encountering problems.
