Thanks for posting a detailed response about your inventory issue, @Operations_Monkey.

Let's dig in and perform some troubleshooting steps to narrow down the cause of the problem. 

To start, let's open a sample company in your QuickBooks Desktop (QBDT) and test to see if this will also have quantity on hand issues. Here's how:

1. If you're currently working in your company file, go to the File menu and select Close company. If not, open your QuickBooks Desktop (QBDT) and proceed to step 2.
2. Then, from the No Company Open window, select the Open a sample file option. 
3. Select the file you want to access. Once opened, create a sample item with the same on hand quantity (14). 
4. When finished, create a Sales Order for the sample item and enter 7 in the Ordered column. Click Save & Close when done. 
5. Next, go back to the Lists menu to check if everything is correct.
6. Select Item List and highlight the sample item.
7. Then, click the Reports drop-down arrow and choose QuickReport. 
8. From there, check if the report's data is the same as what's on the Item List page.

You can also perform the steps on other company files to verify if this is only a file issue (file issues can be fixed by verifying and rebuilding the data). If the problem occurs to all other companies and sample files, we may need to repair your QBDT program. Before doing so, please create backup copies first. This is to ensure you have the original information that you can restore in case of accidental data loss or damage. 

If all other companies are fine, I highly recommend reaching out to our Technical support team to further guide you in resolving the issue. Once connected, you can also request a screen-sharing session so they can review your set up. 

It's also easy to run inventory reports to track the status of your item as well as the transactions linked to them. To get started, simply go to the Reports tab and hover over the Inventory section. From there, choose the report you want to open.
