In most cases, connecting your CommBiz account to ACSISS My Data is usually a straightforward process.
However, if you don't see the business account you intend to connect, this means that you haven't chosen at leas one delegate for your CommBiz account.
Nominate a delegate
CommBank requires businesses to choose at least one delegate before data can be shared to third parties. A delegate can share some of your business data with accredited organisations such as ACSISS MY Data without further approval.
To choose a delegate, follow the steps in this help article from CommBank.
After designating a delegate for your account, the delegate will be able to link your CommBiz account and provide ACSISS My Data with the necessary consent to access your bank data.
