Hi @paulstewart1940,

Thanks for joining the Community. I can guide you through making certain accounts in the Chart of Accounts inactive. 

Users can delete accounts in QuickBooks Online that they're no longer using. When an account has been deleted, it will appear as inactive in the Chart of Accounts. The deletion of an account will not erase the transactions contained in there, so reports won't change. Here's how to delete an account:

1. Click the Gear icon.
2. Select Chart of Accounts.
3. Locate the account that you'd like to delete. 
4. Select the drop-down in the Action column and press Delete.
5. Click Yes when asked if you want to delete.

I've included a video to serve as a visual guide:

You can restore a deleted account at any time. Additionally, if the account has a non-zero balance then an adjusting transaction will be made. For additional information about this and deleting accounts, I recommend the following article: How to Delete an Account and Restore It.

With these steps and article, you'll be able to make an account inactive in just a few clicks. 

The Community has your back and is happy to assist anytime. Wishing you well.
