# Code Review Billing

> Free trial, seats, spillover, and subscription lifecycle for Code Review.

Each developer with Code Review enabled counts as one 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 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 that period.

  <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 resubscriptions

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.
