How it works
E-invoicing doesn’t mean a new invoice format — you raise your invoice as usual, then report it to the IRP. The portal validates it, assigns a unique IRN, and digitally signs it with a QR code. Only then is it a valid tax invoice. The data also auto-populates your GSTR-1 and e-way bills.
Software does the work
In practice, your accounting/ERP or billing software connects to the IRP via API (or a GSP) and generates the IRN automatically as you save the invoice — you rarely visit the portal manually except for one-off invoices. Small taxpayers can use the offline/bulk tools provided. Check whether e-invoicing applies to you first.
A worked example
Example: a business above the e-invoice turnover limit raises a sales invoice in its software; the software sends it to the IRP and instantly receives the IRN and QR code, which print on the invoice given to the customer. No IRN means the invoice isn’t legally valid and the buyer’s ITC is at risk. Our team can set up your e-invoicing flow.
