This is a regular taxpayer, so it charges GST on its invoices. You can claim ITC once it reports your invoice in its GSTR-1 and the invoice appears in your GSTR-2B.
It is enabled for e-invoicing on the GST portal, which generally means its turnover has crossed ₹5 crore in a year. Its B2B invoices should carry an IRN and a QR code; an invoice without them isn't a valid tax invoice and can't support an ITC claim.
It has filed GSTR-1 by the due date for every period on record, so invoices it issues to you should show up in your GSTR-2B on schedule.
Filed GSTR-1 by the due date for all 6 months on record, on average 2 days before the due date.
Filed GSTR-3B by the due date for all 5 months on record, on average 1 day before the due date.
Based on returns on record as of 10 Oct 2026, measured against the standard due dates
(GSTR-1: 11th of the next month, 13th for quarterly filers; GSTR-3B: 20th, or 22nd/24th for quarterly filers).
One-off government extensions aren't counted.
