We appreciate the steps you've taken to rectify the situation, @s1b. I'm here to help you find the best support to address the purchase order quantity issues in QuickBooks Online (QBO).

Before doing that, I suggest reviewing another report, the Open Purchase Order List, to cross-validate if there's still an open PO. Once confirmed, we can perform basic troubleshooting steps to see if it's a browser issue. Sometimes, your browser's cache and cookies become corrupted, causing problems when accessing websites or opening files. Let's open your QBO account in an incognito window. It will prevent the browser history from being saved. Please refer to the following keyboard shortcuts based on your browser type:

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

If the incognito works, clear your browser's cache. This action will refresh the system and help you resolve any issues caused by stored cache and cookies. If the problem persists, I recommend contacting our QuickBooks Online Support to investigate this matter.

Here's how :

1. Sign in to your QuickBooks Online company.
2. Select Help.
3. Type in a brief description of your issue, then select:

• Start a chat with a support expert.
• Get a callback from the next available expert.

Additionally, you can refer to this article about tracking bills and recording payments: Enter and manage bills and bill payments in QuickBooks Online.

Please let me know if you have any other QuickBooks-related concerns. I'm always available to help. Stay well.

Per your instructions:

 - I used Private Relay

- I cleared browsers.

I confirmed this is not an issue caused by stored cache and cookies.

Also, as I mention in my original post - this problem is happening in the APP for Windows and Mac. You don't list any instructions/recommendations on attempting to fix these platforms.

I reviewed and reconciled all of my OPEN PO's.  

As a test, I  deleted a PO, the corresponding Bill and Payment to see if the QTY ON PO would change to zero and it did not.  Then I re-entered the PO, entered the Bill, and paid the bill.  Now that product has doubled the QTY ON PO.   There is NO open purchase order.

My vendors require Purchase Orders.  Also, issuing Purchase Orders is a standard procedure, why would I bypass that and only enter a Bill?  

This problem is not happening on all Purchase Orders/Bills.  I don't know why the system is only doing this on some products.  

I confirmed the POs and Bills are linked and the PO says "Closed."
