# Billing and Payments

> Understand Friendli Suite prepaid billing, manage payment methods, view invoices, and learn how credits are applied to usage.

Friendli Suite applies available [credits](/guides/suite/credits) to your usage first. Teams use prepaid credits: once your credits are used up, API requests stop until you add more credits.

## How Billing Works

1. Credits are applied to your usage first, based on the [order of consumption](/guides/suite/credits#order-of-consumption).
2. Once your credits are used up, API requests stop until you add more credits, either manually or through Auto Recharge.

### Outstanding Balances

How an outstanding (negative) balance is handled:

* **Prepaid billing (default)**: If your balance reaches \$0 (or goes slightly negative due to asynchronous billing), API requests stop until you add credits.
  * Credits you add are applied to any outstanding balance first.
  * Want to use **postpaid billing** instead? [Contact us](mailto:support@friendli.ai).

## Accepted Payment Methods

* **Credit and debit cards:** All major credit and debit cards are accepted, excluding prepaid cards.
* **ACH:** Available upon request. [Contact us](mailto:support@friendli.ai) to set up ACH payments.
* **AWS Marketplace:** Payments can be made directly through the [AWS Marketplace](https://aws.amazon.com/marketplace/pp/prodview-o2qc23xrtfo36).

<Note>
  Splitting a single charge across multiple payment methods is not currently supported.
</Note>

## Managing Payment Methods

One of your registered payment methods must be set as the **default payment method**.

* You can add, remove, or change the default payment method **within the same type** at any time (for example, between two credit cards).
* You cannot delete the last remaining payment method.
* Switching the **type** of the default payment method (for example, from ACH to a credit card, or from AWS Marketplace to ACH) is not supported in self-service. [Contact us](mailto:support@friendli.ai) for assistance.

## Invoices

All previous invoices and current usage can be viewed and downloaded from the "[Billing History](https://friendli.ai/suite/~/setting/billing/history)" tab in [**Friendli Suite > Team Settings > Billing**](https://friendli.ai/suite/~/setting/billing/overview).

You can add your business name or other details to invoices via Stripe's customer portal, which is accessible from the "[Profile](https://friendli.ai/suite/~/setting/billing/profile)" tab in [**Friendli Suite > Team Settings > Billing**](https://friendli.ai/suite/~/setting/billing/overview).
