Great to have you back, @rbkoffice. I'm here to clarify a few things about making an account inactive in QuickBooks Online (QBO).

Yes, you're correct that all recorded transactions associated with any deactivated account will stay intact, whether it's an income or expense transaction. QuickBooks makes accounts inactive instead of deleting them so that you can access past transaction data for reporting purposes.

In other words, your existing transactions don't disappear after deactivating an account and stay on your financial reports. You can also read through this article to learn more about this process: Make an account inactive on your chart of accounts in QuickBooks Online.

Keep me posted if you still have more questions about managing your accounts in QBO. I'll be here to lend a helping hand. Have a great day ahead!
