Hi there,
Syncing your bank account with QuickBooks Online is a great way to keep track of your income and expenses, as well as speed up your reconciliation. Sometimes your banking needs change, however, and it's important that you can disconnect your bank account from the Bank Feed as easily as you connected it. I'll help explain the steps below.
Here's how to remove the bank or credit card account:
1. Click the Banking tab on the left navigation menu.
2. Click the small Pencil icon next to the account you want to unlink.
3. Select Edit account info.
4. Check off the box next to "Disconnect this account on save".
5. Click Save and Close.
This will remove the account from Quickbooks Online. I hope this gets you back on track.
Have a great day!
