On my Purchase OrderI cannot order Item - there is only Category ?

Hello, @royo. The Item and Category details should be available on the Purchase Order view. Since you're unable to see it on your end, we'll troubleshoot your browser to pinpoint why this option isn't showing up.
 

To start, open your QBO account in an incognito window to isolate the problem. Here are the shortcut keys you can use:
 

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

If you don't get the error while using incognito mode, return to your regular browser and clear its cache to remove any stored data that may be interfering with QBO's performance. Alternatively, you might want to consider switching to another supported one.
 

Once this is done, feel free to continue processing your purchase orders.
 

QuickBooks Online offers you the flexibility to record your purchase orders as a bill or an expense, depending on your accounting needs. This feature can help streamline your financial tracking by categorizing these transactions appropriately. For a detailed guide on how to set this up, refer to this resource: Add purchase orders to expenses, bills, or cheques in QuickBooks Online.
 

Please let me know how it goes. I'm here to help and will keep this thread open for any further questions you might have. Have a great day!
