Unlink Bank accounts in our quickbooks. I wan to unlink the credit cards from our quickbooks since I have been having issues with duplicated transactions.

Thanks for coming to the Community for help, @william21.

I can walk you through the steps in disconnecting the account in QuickBooks Online.

Before we proceed with the process, make sure to add and match all the pending transactions in the Banking page. Disconnecting the automatic online banking will delete any transactions in the For Review tab.

Here’s how:

1. Go to Banking on the left pane, then select the Banking at the top.
2. Select the account you want to unlink, then click the Edit icon and Edit account info.
3. In the Account window, put a checkmark to Disconnect this account on save.
4. Click on Save and Close.

Here’s an article for additional information about the steps: Disconnect or delete an account from the Downloaded Transactions page.

I also added this self-help article for your future reference about managing accounts in QuickBooks.

That’ll do it. Come back if you need anything else.
