Do you provide a GST Tax Invoice with our CA firm’s GSTIN?

Yes. Every subscription invoice is issued under SAC code 998315 with full B2B GST compliance. You can claim 18% Input Tax Credit (ITC) on your firm’s GSTR-3B.

How does the CORS pro-rata refund guarantee work?

We offer a mathematically defined refund policy: Refund = Total Paid − (Active Days × Daily Rate). If you cancel an annual plan mid-cycle, you are only charged for the active calendar days used.

Can we use our existing firm WhatsApp number for client reminders?

Yes. CORS supports Bring Your Own Key (BYOK) via the official Meta Cloud API, Aisensy, WATI, or Interakt. Client reminders originate from your firm’s verified number.

What happens to our client records and documents if we ever cancel?

You maintain 100% data ownership. You can export client databases to Excel and bulk-download all uploaded compliance PDFs/documents in a secure ZIP archive anytime before account termination.
