Hi berguy,

I'm here to ensure you're able to connect your American Express Business Checking account.

When connecting your American Express Business Checking account in QuickBooks Online (QBO), make sure to take note of the following:

• Correct bank name. It's important to verify the name of the bank from the list as some banks have multiple names.
• The bank might not connect to all types of accounts (for example, personal accounts vs. business accounts).
• The bank is supported by QBO.

If the above-mentioned were verified but you're still unable to connect your bank, I recommend reaching out to your financial institution as they may be having system maintenance.

Then, you can go back to QuickBooks and try adding your bank account again.

Here's how:

1. Select Banking from the left menu.
2. Click Add Account.
3. Search your bank or use the correct URL when you log in to your bank's website.
4. Enter your bank's username and password.
5. Select the type of account.
6. Choose how far back you want to download bank transactions.
7. Click Connect.
8.
