# Billing

> Manage your subscription plan, purchase credits, monitor usage costs, and access billing history.

The **Billing** page is where you manage the financial aspects of your Agni workspace. Agni operates on a hybrid model: you must first select a baseline monthly subscription plan, which then unlocks the ability to purchase prepaid credits for your usage.

## Credits & Usage

Because real-time voice AI incurs immediate compute and telephony costs, Agni uses a prepaid credit system for call volume. Your agents consume these credits dynamically as they handle live calls.

<Note>
  **Important:** You must have an active subscription plan (Starter, Growth, or Scale) before you can purchase usage credits.

<Warning>
  If your credit balance reaches zero, your agents will be temporarily paused and active dispatch rules will fail to connect. Ensure you maintain a positive balance to avoid service interruptions.

## Billing History

At the bottom of the page, the **Billing History** table provides a transparent ledger of your past transactions.

Whether you are purchasing prepaid credits or paying for your monthly subscription plan, your official invoices and receipts will automatically populate in this table. You can download them at any time for your accounting and tax records.

## Cost Optimization Tips

<AccordionGroup>
  <Accordion title="Set max call duration limits" icon="stopwatch">
    In your agent's [Call Settings](/guides/agents), set a **Max duration** to prevent runaway calls from consuming excessive credits. 30 minutes is a good hard limit for most use cases.
  </Accordion>

  <Accordion title="Enable end-call-on-silence" icon="volume-xmark">
    Turn on **End call after silence** in your agent settings to automatically disconnect calls where the caller has gone silent, avoiding wasted credits.
  </Accordion>

  <Accordion title="Monitor analytics weekly" icon="chart-line">
    Check the [Analytics dashboard](/guides/analytics) regularly. Watch for unexpected spikes in call volume or duration that could indicate prompt issues or campaign misconfiguration.
  </Accordion>

  <Accordion title="Use the right model for the job" icon="microchip">
    Not every use case needs the most powerful model. For simple routing or FAQ agents, Thunder Emotion Lite performs exceptionally well at a lower computational cost.
