Learn how to fix bank connection error 350 in QuickBooks Online andIntuit Enterprise Suite.

Error 350 means that the secure connection between our app and your bank has expired or no longer works. This usually happens for security reasons. Fix this to reconnect your bank and download transactions again.

Important: These two best practices prevent the most common causes of connection errors.

  • Have one person handle all bank connection setups and maintenance for your QuickBookscompany.

  • When reconnecting, always select All Accounts when your bank asks which accounts to share. Do this even if you only use a few accounts in QuickBooks.

Error 350 happens if the connection to your bank or credit card account expires or gets updated. Depending on your bank, you might need to reconnect every 90 business days or every 18 months.

Have the original user who set up the bank connection re-establish it. To do this, select Send a request in the error message. An email will be sent to them with a link allowing them to log back into QuickBooks Online.

Here’s how to fix it: 

  • Go to All apps A bunch of numbers and letters on a tile wall., then Accounting, then Bank transactions (Take me there).

  • Select the bank or credit card account you want to reconnect.

  • Look for the error message and select Fix now.

  • Confirm the user ID and password you use to sign in to your bank's website. Re-enter your bank info if needed.

  • Select Save and connect.
    Note: You'll see a Connection complete and transactions updated! prompt if you reconnect successfully.

  • Select Close.

Tip: If the issue persists, sign in to QuickBooksusing an incognito or private browser or try other browser troubleshooting options.

Error 350 might happen when multiple QuickBooksusers share the same bank login for separate companies. Your bank supports only one active connection, so each reconnection restores one company but disconnects the others.

Note: The most recently reconnected company takes over. All other companies lose access to the connected bank. This creates a cycle where every reconnection fixes one company but disconnects another.

Prevent error 350 with the primary user approach

When multiple QuickBooksusers manage their own reconnections with the same bank login, the cycle continues. Having one designated person handle all reconnections is the best way to resolve this. Here’s how:

  • Select one QuickBooksuser to manage all banking tasks across your connected companies. This person should:

    • Add bank accounts

    • Update connection settings

    • Fix or re-authorize connections

  • Other team members can still do tasks that won't affect the bank connection. Such as:

    • Refresh the bank feed

    • Categorize transactions

    • Reconcile as usual

Tip:  If you’re still seeing the error, contact QuickBooks support. Our team’s happy to look into your specific account setup.
