How to Fix QuickBooks Online Error 324 (Account Not Found at Bank)

Solve QuickBooks Error 324 (account not found at financial institution). Steps to reconnect changed account numbers or manually import transactions via .QBO Web Connect.

Symptom

QuickBooks Online displays: "Error 324: QuickBooks can’t find your account on your financial institution’s website." The account card shows a disconnection warning.

Root Cause

The bank changed your account number, upgraded your account type (e.g. from personal to commercial checking), or consolidated accounts during a bank merger.

Why Intuit Sync Fails

Intuit queries the bank using the previous unique account identifier. When the bank returns a 404 or new account index, QuickBooks stops the feed until manual re-linking.
