Terms
Terms of use
The short version: this site is free, it is a pre-check and not the IRP, and it is not advice.
Free to use
The IRP pre-check and the IRP error pages on this site are free to use. There is no sign-up.
A pre-check, not the IRP
Only the IRP can accept or reject an invoice. A clean result here does not mean the IRP will accept the invoice.
INTSORA is not affiliated with GSTN or NIC. The error messages quoted on the error pages are NIC's own wording, from its published list.
Not advice
Nothing on this site is tax, legal or accounting advice. Check with your chartered accountant before you act on it.
Provided as it is
We work to keep the rules and lists on this site current. We do not promise that every result is complete or correct, and, as far as the law allows, we are not liable for any loss that comes from using the site.
Law
These terms are governed by the laws of India.
