I can't connect my Kabbage checking account, which is managed under American Express now. I have tried to connect via all the Amex links and does not work.

I appreciate your efforts trying to link your Kabbage checking account to QuickBooks, sparkvht.

I can provide some insight into this online banking setup matter. You may encounter an issue connecting your bank if:

• Your bank has multiple names on our list. 
• Your bank does not connect to all types of accounts.
• It's not a participating financial institution.

If you cannot see the bank you wish to connect with after entering the bank's name or URL, likely, Intuit does not yet support it. Given this information, I'd suggest seeking a bank request from our engineers. Let me show you how:

1. Go to the Banking menu and select Connect account.
2. Type your financial institution link in the box and click the Still can't find your bank?
3. Enter your bank's web address (URL) in the field provided and click Request.

Alternatively, you can manually upload transactions downloaded from your bank's website to QuickBooks Online. This way, you can still categorize the transactions. 

 Go as follows:

1. Go to the Banking menu and select Upload transactions.
2. Select Browse and choose the file you downloaded from your bank. 
3. Click Next.
4. Select the account you want to upload the transactions into in the QuickBooks account ▼  dropdown and hit Next.
5. Follow the on-screen instructions.
