Troubleshooting & Common Questions

Why does my GSTIN show a validation error?

Root Cause: A GSTIN must strictly follow the 15-character format: 2-digit state code + 10-character PAN + 1 entity number + 'Z' + 1 checksum digit, with no spaces or symbols.

Resolution: Check your GST certificate. Ensure the first 2 digits match your billing state (e.g., 33 for Tamil Nadu, 29 for Karnataka, 27 for Maharashtra).

Why is IGST charged instead of CGST + SGST?

Root Cause: Orbion Agents operates from Tamil Nadu. Any customer state outside Tamil Nadu is classified as an Inter-State supply subject to 18% IGST.

Resolution: If your corporate business operates within Tamil Nadu, ensure 'Tamil Nadu' is entered in your billing state to apply 9% CGST + 9% SGST.

Invoice PDF download does not start or opens a blank window?

Root Cause: Browser popup blockers or download restrictions may intercept the PDF file stream.

Resolution: Allow popups and file downloads for the Orbion domain in your browser settings, then click 'PDF' again.

Will updating my GSTIN update past invoice receipts?

Root Cause: Tax invoices are immutable legal documents recorded at the time of payment transaction.

Resolution: Saved GST details apply automatically to all subsequent transactions. For accounting corrections on older invoices, contact support with the invoice reference ID.
