E-Invoicing Is Now Mandatory for Millions of Businesses
The Indian government has progressively expanded e-invoicing requirements. As of 2024, all businesses with annual turnover above ₹5 crore must generate e-invoices for B2B transactions. This threshold continues to lower — within 2 years, most registered businesses will be covered.
E-invoicing means registering every B2B invoice on the Invoice Registration Portal (IRP) before issuing it to the buyer. Without integration in your billing software, this is an extremely tedious manual process.
⚠️ Legal Requirement: Invoices that are not registered on IRP are invalid for ITC purposes. Your B2B customers cannot claim ITC from your invoices if you don't generate proper e-invoices with IRN.
How E-Invoice Works in India
- Business creates B2B invoice in their billing system
- Invoice data is sent to IRP (Invoice Registration Portal)
- IRP validates the data and assigns a unique IRN (Invoice Reference Number)
- IRP generates a QR code containing the invoice data and IRN
- Invoice is returned to the business with IRN and QR code embedded
- Invoice is shared with the buyer — who can verify on the GST portal
