# I’ve converted a purchase order to a bill but the status of the purchase order has not been updated to closed. What is the reason behind it?

By default the status of a Purchase Order (PO) becomes **Closed** when you create a bill from the purchase order. However, if the [inventory add-on is enabled](https://www.zoho.com/books/help/items/advanced-inventory.html), then the PO will be closed based on the preference chosen in the PO general preference settings. To check this:

*   Go to **Settings** in the top right corner.
*   Select **Purchase Orders** under _Purchase_.
*   Chose the required preference based on when you wish to close the purchase order.
*   Click **Save** to update your changes.
