How can I delete a Class that is not used? (Quickbooks Desktop for Mac)

Hey there, @LVT.

Let's pull up some report to make sure that your classes aren't assigned to anything.

There are multiple places where you can assign classes. These include your accounts, items, transactions, and names. You'll need to pull up several reports to make sure that your classes aren't used in any of these.

First, let's pull up your Item Listing report. Here's how:

1. Click on Reports from the menu bar.
2. Hover your mouse on List, and select Item Listing.
3. Click on Customize Report.
4. In the Columns box, select class.
5. Click on the Filter tab.
6. In the Choose Filter box, click on Class, and select the unused class.
7. Click on OK.

Next, you need to pull up your Customer, Vendor and Employee Contact List. This way you'd know if you've assigned classes to them. You may follow these steps.

1. Click on Reports from the menu bar.
2. Hover your mouse on List.
3. Choose Customer Contact List, Vendor Contact List, and Employee Contact List one at a time.
4. Click on Customize Report.
5. In the Columns box, select class.
6. Click on the Filter tab.
7. In the Choose Filter box, click on Class, and select the unused class.
8. Click on OK.

Lastly, you need to pull up your Chart of Accounts list to know that the unused class is not used in any of them. Here's how:

1. Click on Lists from the menu bar.
2. Click on Chart of Accounts.
3. Right click on the page, and click on Customize Columns.
4. From the Available Columns box, click on Class.
5. Click on Add.
6. Click on OK.

Once you've verified that the class is not used in any of these and still unable to delete it, you can run the Verify and Rebuild Data utilities.

1. To Verify Data:
   1. Click on File from the menu bar.
   2. Hover your mouse on Utilities.
   3. Click on Verify Data.
   4. If you see QuickBooks detected no problem with your data, select OK.
   5. If Verify finds an issue with your data, you will be prompted to Rebuild Now or View Errors.
2. To Rebuild Data:
   1. Click on File from the menu bar.
   2. Hover your mouse on Utilities.
   3. Click on Rebuild Data.
   4. On the QuickBooks Information window, select OK. Note that as long as the cursor is moving while displaying QuickBooks not responding, the rebuild is still ongoing.
   5. Select OK when you see Rebuild has completed.

Once done, you can delete your unused class again from your class list.
