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.
