# Manage your Monorail AI subscription and billing

> Learn how to upgrade, downgrade, or cancel your Monorail AI plan, update payment details, check your credit balance, and resolve billing disputes.

You can manage your Monorail AI subscription entirely from the billing section of your dashboard. Upgrade or downgrade your plan at any time, view your credit balance, and update your payment details.

## Changing your plan

<Steps>
  <Step title="Sign in">
    Go to [mnrl.app/app](https://www.mnrl.app/app) and sign in to your account.
  </Step>

  <Step title="Open Billing">
    Navigate to **Billing** in your dashboard.
  </Step>

  <Step title="Select a plan">
    Choose your desired plan: Freemium, Pro, Pro+, or Ultra.
  </Step>

  <Step title="Confirm your selection">
    Upgrades take effect immediately. Downgrades take effect at the end of your current billing period.
  </Step>
</Steps>

<Note>
  Downgrading your plan does not issue a refund for the remaining time on your current period. Your current plan remains active until the next billing date.
</Note>

## Cancelling your subscription

To stop recurring charges, downgrade to the Freemium plan before your next renewal date. You can do this from the **Billing** section of your dashboard.

* Cancellation stops future billing but does not refund any charges already made.
* After downgrading, you retain access to Freemium-level features indefinitely.

## Credit balance

Your credit balance is shown in your dashboard at all times.

* Credits refresh each billing cycle for paid plans.
* Unused credits do not roll over to the next period.
* Credits have no cash value and cannot be transferred between accounts.

## Billing errors and disputes

If you believe you were charged incorrectly, contact [support@mnrl.app](mailto:support@mnrl.app) within 14 days of the charge. Include the following in your message:

* Your account email address
* The transaction reference number
* A description of the suspected error

<Warning>
  Do not initiate a chargeback with your bank without first contacting support. Chargebacks may result in immediate account suspension.
</Warning>

## Updating payment details

Payment details can be updated in the **Billing** section of your dashboard. Monorail AI uses a third-party payment processor — your full card details are never stored on Monorail AI servers.
