# Trial and billing

> Understand Code Review payment methods, trials, seats, and subscription lifecycle.

Code Review billing is based on Code Review seats. A seat covers one developer whose pull requests or merge requests can be reviewed by Hacktron.

Organization owners manage payment methods, invoices, billing details, subscription state, and promotion codes from **Billing**.

## Start a trial

Code Review has a free trial for new organizations.

<Steps>
  <Step title="Open Billing">Go to **Billing** as an organization owner.</Step>

  <Step title="Start the trial">
    Review and accept the terms of service and start the trial. No payment method
    is required during the free trial.
  </Step>

  <Step title="Start the Code Review trial">
    Once the trial is active, Hacktron starts running code reviews on all
    covered repositories.
  </Step>
</Steps>

## How seats are billed

Each developer with Code Review enabled counts as one Code Review seat.
Seats can be assigned manually, or Hacktron can assign seats automatically
when developers open pull requests in covered repositories.

Code Review is billed as a monthly subscription. At the end of each billing period,
your organization is charged for the number of Code Review seats that were active
during that period.

<Info>
  If a developer no longer needs Code Review, remove their seat from **People**.

  The removed seat can be reassigned to someone else during the same billing period,
  but removing a seat in the middle of the billing period will not reduce the
  seat count for the current billing period.
</Info>

## End a trial early

Ending the trial early allows you to start the paid plan immediately and enable [spillover usage](/code-review/spillover-usage).

<Steps>
  <Step title="Open Billing">Go to **Billing** as an organization owner.</Step>

  <Step title="End the trial early">
    Go to **Billing** and end the trial early to start the paid plan immediately.

  </Step>

  <Step title="Enable spillover">
    Go to **Usage** to enable spillover billing to continue reviewing pull requests or merge requests
    after the pooled review limit is reached.
  </Step>
</Steps>

## Cancellations and resubscription

If you cancel during a trial or paid subscription, Code Review remains available
until the end of the current trial or billing period. After cancellation takes effect,
new pull requests or merge requests are no longer reviewed.

If the organization resubscribes later, Code Review starts as a paid subscription.
The free trial does not restart.
