Has anyone tried registering Quickbooks Online as CAS with BIR?

While waiting for others to share their experiences, please note that you can submit your Computerized Accounting System (CAS) application through the BIR’s Online Registration and Update System (ORUS). From there, you'll have to upload the required documents in JPEG, PNG, or PDF format with a maximum file size of 25MB.

Let me know if you have follow-up concerns. We'll be here to assist you.
