You can merge accounts in the Chart of Accounts in QuickBooks Online, @Blondie18.
Beforehand, I appreciate the details you shared about the assistance you need with merging accounts in QBO. To start, you’re correct that both connected bank accounts in QBO need to be disconnected first. Let me guide you through the steps:
- In the My Apps, click Accounting and go to Bank Transactions.
- Select the tile for the bank account.
- Choose the Pencil icon, then select Edit account details.
- Select the Disconnect this account on save checkbox and hit Yes.

After that, you’re ready to merge the accounts. Here’s how:
- From the Accounting column, select Chart of Accounts.
- Open the account to keep, click the Action dropdown, and hit Edit.
- Note the Account Name, Type, and Detail Type, and return to the Chart of Accounts.
- Find the account you want to merge, then click the Action dropdown and select Edit.
- Update the Account Name and Detail Type to match the account you want to keep.
- If done, click Save. A prompt will appear; select Yes, merge accounts to confirm.

Once completed, you can reconnect the account you kept during the merging process.
