Hi there, Alice. When upgrading to Open Banking feeds, you'll need to provide your Australian Business Number and nominate a representative as part of the two security steps required by Australian regulations.
If you have received an invitation to upgrade, completing these two requirements is necessary for the process to succeed. If you aren't able to provide them, it’s likely why the upgrade is failing.
Once these details are submitted, you'll be able to use your new feeds. For more detailed guidance, feel free to check out our blog: The Next Generation of Bank Feeds for QuickBooks.
Don't hesitate to reply here if you need anything else. We're here to help.
