Can you reverse an account on the general ledger that was made inactive by mistake

Hi there, 

QuickBooks makes it simple to reactivate an inactive account and I'd be glad to show you how. 

An inactive account can be reactivated with just a few clicks in QuickBooks Online:

1. Click Accounting on the left navigation menu and choose Chart of Accounts.
2. Select the small Gear icon above the Action column and choose Include inactive.
3. Click Make active next to the inactive account.

For more information, check out this helpful article here: Delete an account on your chart of accounts in QuickBooks Online.

Give this a try and if you need further assistance, I recommend contacting our support team using this link.
