Hi there, jshields123. I can see the importance of having Quantity (QTY) field onn your Purchase Order (PO). Let me share some details and guide you on how to add QTY on purchase orders.

By default, when creating a purchase order the QTY field is already added. You just have to add them in the Item Details section because this field isn't available in the Category Details section. Here's an illustration for your reference:

If in any case the QTY column doesn't appear in your Items section in your PO, you can perform troubleshooting steps to see if this has something to do with any underlying browser issues. We'll start by accessing your QuickBooks Online account in a private/incognito window. Depending on your browser, use the keyboard shortcut below to open one:

• Google Chrome and Microsoft Edge: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P

If the QTY column appears, go back to your regular browsing window and clear the cache. This will remove any outdated and corrupted internet files causing odd behavior in your most visited pages. Alternatively, you can look and use other supported browsers for the best experience while working in QuickBooks Online.

On the other hand, if what you meant is a Quantity field that displays inventory items, you can enable this by following these steps:

1. Click on the Gear ⚙ icon, then choose Products and Services.
   
2. Select the Settings icon beside Export.
3. Tick the Qty on PO box to add the column.
