How do I connect my Zable and Zilch card accounts as they do not appear in the connect accounts screens?

Allow me to welcome you here in the forum, francis-cwb-desi. I'll help with your questions about adding your card accounts in QBO. 

When an account or financial institution doesn't appear as an option for Online Banking in QuickBooks Online, there are a couple of potential reasons:

• The bank may not support connections via Open Banking yet. Open Banking allows the sharing of financial data between banks and platforms like QBO. However, not all banks have adopted this system, so QuickBooks can't always access their data.
• The bank may not have completed its technical integration with QuickBooks for bank feed connectivity.

This Help article provides a list of banks that currently support Open Banking connections in QBO: Banks That Support Open Banking Connections With QuickBooks Online. 

If you can't see Zable and Zilch on the list, you can ask for a copy of your banking transactions and import it into QBO. Let me share these articles as your guide: 

• Format CSV Files In Excel To Get Bank Transactions Into QuickBooks Online
• Manually Upload Transactions Into QuickBooks Online

While not as automatic, manually importing your statement data allows you to get your Zable and Zilch transactions into QBO.

You can use one of the converter tools with a one time license (e.g csv2qbo @ $60) as a workaround
