e-Invoicing Under GST: Thresholds, IRN and How to Comply
e-Invoicing standardises B2B invoices by registering them on the government portal, which returns an IRN (Invoice Reference Number) and a signed QR code.
Who must comply
Businesses with aggregate turnover above the notified threshold (progressively lowered to โน5 crore) must e-invoice B2B and export transactions. B2C is currently excluded.
How it works
- Generate the invoice in your accounting/ERP system
- Push the JSON to the Invoice Registration Portal (IRP)
- Receive IRN + signed QR code
- Share the invoice with the QR to your buyer
Why it matters
Without a valid IRN, the invoice is not legally valid, and it auto-populates GSTR-1 and e-way bills. Non-compliance blocks input tax credit for buyers.
