To help explain how billing, invoicing and payments are managed across the platform, we have a short video guide to take you through Billing Management. ## New Accounts All new accounts receive free credit on their balance as a gift from Airia. There is no work needed to activate your credits and you can start adding models from the model library and running Agents or playground executions free of charge until the balance amount is less than \$1. ## Manage Account There are two ways to manage transactions with Airia. 1. Add money to your account balance 2. Set up autopay Manage Account ## Add money to your account Adding money to your Airia account balance can be done in a few easy clicks. 1.

Navigate to **Settings** 2. Select **Account** and navigate to **Billing** section 3. Toggle on **Auto add funds when balance is low** ## Transaction History For full reporting of your transactions and billing, your Transactions History will record the amount of each transaction, timestamp, and relevant credit card information.
