I'm here to help ensure you can make your client inactive in QuickBooks Desktop (QBDT), @Italian Law.

There are some possible reasons why the Customer is inactive checkbox isn't showing in your QBDT. Here are some of them:

• Your new laptop doesn't meet the system requirements for QBDT 2021.
• Your QuickBooks isn't up to date.
• Your company file may have data issues.

To get this fixed, you'll want to make sure your new laptop meets the system requirements for QBDT 2021. If it meets the requirements and still experiencing the same, I suggest updating your QBDT to the latest release.

If the issue persists, you can run the Verify and Rebuild Utility Tools. This way, we can check if your company file has data damage. For the detailed steps and information, feel free to read this article: Verify and Rebuild Data in QuickBooks Desktop.

Once everything is up and running, you may want to run and customize sales reports in your QBDT. This helps you review your sales transactions entered in your company file.

Should you need any assistance getting your company file up and running, I'm available here to help any time!
