Hi there, antony.

Registering QuickBooks Online to BIR as a Computerized Accounting System (CAS) is currently unavailable. As a workaround, I'd recommend looking for a third-party application connecting to QuickBooks Online. Let me guide how you how:

1. On the left panel, click Apps.
2. Click the Browse Category drop-down list.
3. Click the app so you can check more details.

On the other hand, registering QuickBooks Online to BIR as a Computerized Accounting System (CAS) is a valuable addition to QuickBooks. This way, to lessen your manual work. I suggest sending feedback to our product engineers. They can evaluate this and possibly incorporate it into the subsequent release. 

Let me guide you on how:

1. In your QBO account, go to the Gear icon on the upper right side. 
2. Click Feedback under Profile.
3. Type your suggestion in the box and tap Next. 

QuickBooks has a website where you can vote and give feedback for all future suggestions. For more details, visit this link: Customer Feedback for QuickBooks Online.

I'm also adding this link if you need help with other tasks in QuickBooks, look for topics that suit your concern.
