# How does billing and credit usage work?

> How Fireworks pre-paid credits work across serverless, on-demand deployments, and fine-tuning, plus auto top-up, budget caps, and balance-zero behavior.

> [!NOTE]
>
> Contracted customers may have the option to move to post-paid billing. [Contact our sales team](https://fireworks.ai/company/contact-us) to discuss your options.

Fireworks operates on a **pre-paid credits** billing system. You purchase credits to use the platform:

* Add a valid payment method and billing address, then purchase credits.
* Usage across serverless, on-demand deployments, and training deducts from your credit balance.
* If your balance reaches zero and Auto Reload is not enabled, usage pauses until you add credits.
* You can configure Auto Reload to purchase credits when your balance is low.
* Separately, you can set a monthly spend limit for your usage. Adding credits does not raise this limit.
* Total Spend can lag live traffic by a day or more, especially for newly launched models. A jump in spend is often delayed aggregation, not a traffic spike.

> [!NOTE]
>
> Enterprise accounts do not have the same self-serve limits. Their monthly spend alerts track the cost of Fireworks usage, including usage paid for with credits. Adding credits itself does not count as spend. See [Enterprise quotas](https://fireworks.ai/docs/faq/enterprise/service/quotas) for more information.

> [!TIP]
>
> For details on spend limits and quota controls, see our [Account quotas guide](https://fireworks.ai/docs/guides/quotas_usage/account-quotas.md#view-and-adjust-your-spend-limit).
