# Receive keys

> See the keys a vendor uploads against a purchase order, track how much has arrived, and reset what was received.

Once a purchase order is confirmed, the vendor supplies the keys. Keys uploaded against the PO go straight into your inventory as **Available**, stamped with the purchase order they came from. There is no separate approval step. This page covers receiving keys and undoing an upload.

## How keys arrive

Against a confirmed purchase order, the vendor can upload keys from the Vendor Portal, and you can also upload keys yourself from the PO's detail page with **Upload keys**. Either way, the keys count toward the order and cannot exceed the ordered quantity. Duplicate keys are flagged and can be skipped, and uploads are blocked once the PO is Closed.

Each upload records who made it, so the key's history shows whether you or the vendor added it.

<Info>
  The PO detail page shows fill progress under **Inventory Received** as received against ordered, with a bar that turns green once every ordered key has arrived. Received keys are listed under the progress bar, masked, just as they are in your inventory.

## Check the keys

<Steps>
  <Step title="Open the purchase order">
    Open **Purchase Orders** and select the PO. The received keys appear in the **Inventory Received** section.
  </Step>

  <Step title="Review the keys">
    Check the received keys against what you ordered. You can export them as a TXT or CSV file with **Export**.
  </Step>

  <Step title="Reset if something is wrong">
    Select **Reset** to remove the keys received against this PO that are still **Available**. Keys that are already sold or reserved are kept. Type `DELETE` to confirm. Reset is not available once the PO is Closed.
  </Step>
</Steps>

<Note>
  Received keys are normal inventory you can sell right away. From your product's key list you can trace each key back to the PO that supplied it. See [Manage stock](/guides/products-inventory/manage-stock).
</Note>

## What the vendor can do

From the Vendor Portal, a vendor can also:

* Add notes to the keys they supplied against your purchase order.
* Replace a faulty key they supplied with a new one. This works even if the key is already sold or reserved, and the key keeps a record of the replacement.
