As per NIC, the invoice details will be reflected in GSTR-1 data on the GST portal within 24 hrs of IRN generation. If the invoices are not reflecting after 24 hrs please raise a ticket with the GSTN team along with the invoice and IRN details at https://selfservice.gstsystem.in/ or call them at 1800-103-4786 for further assistance.

If i generate an IRN directly on the NIC portal, does it reflect in Clear E-invoicing?

If IRN is generated directly on the NIC portal those invoices will not be updated in the cleartax portal.

I can't find my Generated Invoice

Make sure you've chosen the right set of filers on the documents page. You can identify/search relevant e-invoice documents by narrowing your search using the filter options below: Document date IRN generation date Business Document number Customer name/GSTIN Document Status Supply type Document type Tax value

Please note: Document date is the date on which the original invoice number was raised. While the IRN Generated date will be the date you actually generate an IRN for that invoice. As a general rule your document date will always be less that or same as IRN generated date.
