# Cancelling accessions

> How to cancel and restore accessions in bLIS.

## Overview

Cancelling is the preferred way to stop work on an accession. Unlike [deleting](/guides/deleting-accessions), cancellation preserves the accession record and requires a reason, providing full traceability.

## How to cancel an accession

<Steps>
  <Step title="Open the accession">
    Navigate to the accession you want to cancel.
  </Step>

  <Step title="Open the action menu">
    Press `Ctrl+K` to open the [command menu](/guides/command-menu), or click the overflow menu (**...**) in the upper right corner of the accession.
  </Step>

  <Step title="Select Cancel accession">
    Choose **Cancel accession** from the menu.
  </Step>

  <Step title="Enter a reason">
    Provide a reason for the cancellation. This is required for audit purposes.
  </Step>
</Steps>

## What happens when you cancel

When you cancel an accession:

* The accession status changes to **Cancelled**
* All associated [test orders](/concepts/test-orders) are cancelled along with it
* Billing considerations apply to the cancelled test orders as well
* The cancellation reason and timestamp are recorded in the audit trail

<Warning>
  Cancelling an accession cancels all of its test orders. Review the accession's test orders before proceeding.
</Warning>

## Restoring a cancelled accession

You can restore a cancelled accession to its previous state.

<Steps>
  <Step title="Open the cancelled accession">
    Find the cancelled accession in the accession list (filter by **Cancelled** status if needed).
  </Step>

  <Step title="Click Restore">
    Click the **Restore** button displayed on the cancelled accession.
  </Step>
</Steps>

The accession returns to the state it was in before cancellation.
