Our bank has sold. How do we change in QuickBooks online?

Hi karen170!

Let me help you in setting up the new bank account.

I suggest you set up a new bank account and simply transfer the balance. This is also to ensure that the transactions won't get mixed. You can follow these steps on how to create a new one:

1. Go to the Accounting menu and select Chart of accounts.
2. Click New. Select Bank as the Account Type.
3. Select a Detail Type and enter a Name.
4. Tap Save and Close.

Once done, go to the + New button and select Transfer so you can transfer the funds from the old account to the new one.

In addition, it'd be best to seek some help from your accountant to see what's the best option for your business. I also added this link if you need help in reconciling your accounts: Reconcile an account in QuickBooks Online.
