# Your inventory
> See the stock you have supplied to a store, check each product's keys, and keep their expiry dates and notes up to date.
**Inventory** shows the keys you have supplied to the store you are working in. Open it from the sidebar. You see only the keys you added yourself. If other vendors supply the same product to this store, their keys are not included.
You add keys by fulfilling purchase orders, not from this page. See [Upload keys to a purchase order](/vendor-portal/upload-keys).
## Your stock at a glance
The top of the page shows four numbers for the store you are in:
* **Total keys**, across all the products you supply.
* **Inventory value**, with how many keys are available.
* **Sell-through**, the share of your keys that have sold, with the sold and reserved counts.
* **Needs restock**, how many products are out of stock, with how many are low.
## Find a product
The list has one row per product you hold an offer for, including products you have not uploaded keys for yet. Each row shows the **Product**, **Type**, **Available** (against the total, with a stock bar), **Reserved**, **Sold**, **Inv. Value**, and **Status**. You can:
* Filter by stock with the **All**, **In stock**, **Low stock**, and **Out of stock** tabs. Each tab shows how many products it holds.
* Search by product name.
* Sort by product name, available, reserved, sold, or inventory value.
* Export the list to a CSV file.
Select a product, or choose **View keys** from its row actions, to open its keys.
If the list is empty, you do not supply any products in this store yet. Select **Add an offer** to start. See [Manage your offers](/vendor-portal/manage-offers).
## A product's keys
The product page opens with a summary: the product name, its type, its stock status, its SKU, and a bar breaking your keys down into **Available**, **Reserved**, **Sold**, and **Invalid**.
Below it, the keys table lists each key with its **Ref ID**, **Key**, **Status**, **Added** date, and **Expiry**. Use the **All**, **Available**, **Reserved**, **Sold**, and **Invalid** tabs to narrow the list.
### Reveal a key
Keys are masked in the table. Select a masked key to reveal it, then select **Copy key** to copy it. Each reveal is recorded in the key's activity.
### Key actions
Open the row actions on a key to:
* **View details**: the key's status, the date it was added, its expiry, and its purchase order.
* **View activity**: every event recorded for the key, such as when it was created, revealed, copied, replaced, or had a note added.
* **View notes**: read the key's notes and add your own.
* **Edit expiry**: change or clear the key's expiry date.
### Notes
The **Item notes** dialog shows any note the key carries at the top, then the notes trail. Each note shows its author, a role badge (**Vendor**, **Support**, or **Admin**), and when it was added. To add one, type it in the note box and select **Add note**.
You can add notes to keys you delivered against one of your purchase orders.
### Edit a key's expiry
Choose **Edit expiry** from the key's row actions.
Pick a new date under **Expiry**, or leave it blank for a key that never expires.
Select **Save**.
You can edit the expiry only on an **Available** key that you delivered against a purchase order. Once the store approves the keys on that purchase order, or the purchase order is Closed, the expiry is locked.
## Replace a faulty key
When a store reports a faulty key, you replace it from the support ticket, not from this page. The old value is kept in the key's **Replacement history**, and the replacement shows in the key's activity. See [Handle tickets](/vendor-portal/handle-tickets).
