I can’t connect my QB to my bank account as it’s not on the list of banks existing on QB. Can QB add my bank to the list?

Thanks for joining the Community space, @contact-kaizenwa.

You can request support for your bank so you can connect your bank and credit card accounts to automatically download transactions. into QuickBooks Online.

To get started, there are possible reasons why you can't find your bank account on the list.

• You're using a different name of the bank. Make sure you've entered the correct name of the bank or have tried all possible links. You can search by the banking login URL to ensure you are using the correct listing.
• Your bank is not a participating financial institution.

If you have confirmed the required details, and you still can't find your bank. You'll need to use the Request support your bank option and ask us to add your bank. I'll show you how:

1. Go to the Banking menu or Transactions menu.
2. Click Add account.
3. When you enter your bank and click Find, you'll get the message: Hmm, we can’t find [name of the bank you entered] in our list of supported bank.
4. Click on the button Request support for your bank.
5. Enter the Bank name and Bank web address (URL) in the field, then click Request.

For additional reference, you can check this article: How to identify the correct bank.

Alternatively, you can import your transactions to QBO using the CSV file. For more guidance, you can check out this article: Manually upload transactions into QuickBooks Online.

After adding the transactions, you can start categorizing or adding them into your books. When you're done, you have the option to start reconciling your bank statement.

I'd recommend reading this article for a reconciliation guide: Reconcile an account in QuickBooks Online.

Also, may I know the name of your bank so I can check if there are any reported issues and provide you with updates or workarounds. 

 Please let me know if you have any follow-ups or other concerns. I'm always glad to help.
