I can share a few details about tracking your item serial numbers, @FloridaTractor.
Currently, the ability to track serial numbers is unavailable in QuickBooks Online. In your case, I recommend sending Feedback since this is beneficial to your business. This way, our product developer might add this functionality in future updates.
Here's how:
- Click the Gear icon on the top right.
- Select Feedback below Profile.
- Enter your product suggestion.
- Hit Next to submit.
Moving forward, you may want to enter the serial number on the sales form's product/service description or add a custom field. This way, you can pull up the Sales by Product/Service Detail report to show Memo/Description or custom field column which has the serial number. I've added some screenshots for visual references:


Here's how:
- Click Search on the top right.
- Type product/service and then select Sales by Product/Service Detail report.
- Click the Mini Gear icon.
- Hit Show More.

- Check the Memo/Description or custom field [Serial Number] boxes.


I've also added some references to show and narrow your data targets on some reports in QuickBooks Online:
