Thanks for joining the thread about vendor insurance dates, Kmdesigns.

First, I'd like to confirm if you're referring to losing the vendor insurance expiration date fields after upgrading. If so, possible data damage could be causing this option not to show.

To ensure you can access this again, let's perform troubleshooting steps to help fix unexpected and common issues in QuickBooks Desktop (QBDT) by verifying and rebuilding your company file. Here's how:

First, verify your company data.

1. Go to Window and click Close All.
2. Select File, then choose Utilities.
3. Tap Verify Data. If you see: 
   
   

• QuickBooks detected no problems with your data—your data is clean, and you don’t need to do anything else.
• An error message—search for it on our QuickBooks Desktop support site for how to fix it.
• Your data has lost integrity—Data damage was found in the file. Rebuild your data to fix it.

Then, rebuild your company file data.

1. Select File, Utilities, and then click Rebuild Data.
2. QuickBooks will ask you to make a backup before it rebuilds your company file. Hit OK. A backup is required before you can rebuild.
3. Choose where you want to save your backup, then OK. Don’t replace another backup file. Enter a new name in the File name and tap Save.
4. Tap OK when you get the message Rebuild has completed.
5. Go to File, choose Utilities then select Verify Data again to check for additional damage.  
   
   

• If the verification finds more damage, you’ll need to fix it manually. Search for the error(s) in the qbwin.log on the QuickBooks Desktop support site for how to fix it.
• If your error can't be found, you can restore a recent backup. Go to File then select Open or Restore Company.
  
  

Note: Don’t replace your existing company file. You’ll need to enter the info into your company file again since the backup was created.

Let me know how it goes, Kmdesigns. I'll be here to provide further help managing vendor insurance expiration dates in QBDT.
