QuickBooks error 324 means the bank connection still works but QuickBooks can't find the bank account it was linked to. A replacement card or a new account number is the usual cause. Select Fix now, sign in, consent to all accounts, map the new account to your existing QuickBooks account, and restart downloads from the right date.
What does QuickBooks error 324 mean?
Error 324 is an account-matching problem, not a password problem. Intuit's guide to fixing bank connection error 324 says it appears when QuickBooks can't find your bank accounts. The connection may still be active, yet transactions have stopped downloading for the affected accounts.
Think of the bank connection as a door and each account as a room behind it. Your sign-in still opens the door. The room QuickBooks remembers, identified by an account number or card number, is no longer where it was. Until you point QuickBooks at the new room, nothing downloads for that account, while other accounts at the same bank may carry on normally.
A replacement card or new account number behind error 324
The most common trigger for error 324 is a change of details at the bank. A lost card gets replaced, a card is reissued after fraud, or the bank moves an account to a new number. The bank now reports the account under its new identity, and QuickBooks can't match it to the one on file.
Intuit's guide says you don't need to disconnect in this case. That matters, because disconnecting is where most history problems start. The fix is to sign in again and tell QuickBooks that the new account is the same one it already knows.
If you only learn about the new card when the feed stops, look at the dates. The last line that downloaded tells you roughly when the old card stopped being used.
Reconnecting the account that shows error 324
To clear error 324 after a details change, reconnect through Fix now and map the updated account to your existing QuickBooks account. Mapping to the existing account keeps your history and rules in one place. Mapping to a new one splits them and invites duplicates.
Here is a worked example. The figures are made up. A business card ending 4417 was replaced by a card ending 9032 on 12 May, and the feed shows error 324.
- Go to All apps, then Accounting, then Bank transactions.
- Find the card showing error 324 and select Fix now.
- Sign in with your current bank username and password.
- At the bank's prompt, choose All Accounts or Consent All. Intuit's guide says this only gives QuickBooks a secure connection. It doesn't add every account to your books.
- Map the card ending 9032 to the existing QuickBooks account, the one named for the card ending 4417.
- Finish the connection and wait for the download.
If the card ending 9032 doesn't appear in step 5, Intuit's guide gives a second route. Select Fix now, then Disconnect, and confirm. Then choose Add Account, find your bank, sign in and select the updated card. Map it to the existing QuickBooks account again, not a new one.
Which start date should the error 324 reconnection use?
The right start date after error 324 is the day after the last transaction QuickBooks already holds for that account. Choose any earlier and you pull lines you have already added. Choose a later one and you leave a gap that will surface at reconciliation.
In the example, suppose the last downloaded line on the old card was dated 10 May. If QuickBooks asks how far back to download, pick a range that begins on 11 May. Then compare what arrives with the card statement for May.
A gap is easier to fix than a pile of duplicates. If some days are still missing, download those lines from the bank's website as a file and upload them by hand. Finding the cause of a QuickBooks Online bank upload error helps if that upload is refused. If the bank only offers a spreadsheet and the dates come through wrong, the QuickBooks CSV invalid date error explains how to fix the date column.
Other logins and other companies that trigger error 324
Error 324 can appear when nothing changed at the bank at all. Intuit's guide lists three causes on the QuickBooks side, and all of them come down to how the connection was last approved. Each one replaces the bank's list of accounts that QuickBooks may see.
- A different login was used to reconnect. A spouse's or a second user's login can leave accounts in a mixed state. Intuit's guide says to disconnect the mismatched connections under Manage Connections and reconnect with the original login.
- Fewer accounts were chosen. Picking only one account at the bank during a reconnect removes access to the others. Reconnect with All Accounts or Consent All, then select only the accounts this company needs.
- Several companies share one bank login. Each reconnect replaces the bank's account selection, so another company's accounts can drop out. After fixing one company, switch to the others and refresh their feeds.
Intuit's guide also recommends that one person manages all bank connections, which keeps the logins and account choices consistent.
When error 324 means the bank account is closed
Sometimes error 324 is telling you the account has gone. If the bank closed or suspended the account, it no longer shares data for it, and no reconnection will bring it back. Intuit's guide says to disconnect it instead.
Before you disconnect, review and post any lines still waiting from the closed account. Intuit warns that if you skip this, QuickBooks may report that the account is already connected when you add its replacement. Then disconnect through Fix now and Manage connections, and add the new account with Link account.
