Understanding E-Invoicing in India: The Current Landscape

E-invoicing goes beyond digitizing paper invoices. It’s a government-mandated process requiring electronic authentication of all B2B invoices through the Invoice Registration Portal (IRP). Each qualifying invoice is uploaded, validated, assigned a unique Invoice Reference Number (IRN), and embedded with a legal QR code.

The real game-changer came in 2025. As of April 1, 2025, the mandatory e-invoice turnover threshold applies to businesses with an Annual Aggregate Turnover of ₹10 crore and above. Invoices must be uploaded to the IRP within 30 days of issuance, or you risk rejection and penalties.

Mandatory E Invoice Turnover Thresholds: What’s Changed

Over time, the government has steadily lowered the turnover bar:

October 2020: Above ₹500 crore
January 2021: Above ₹100 crore
April 2021: Above ₹20 crore
2022 onwards: Above ₹10 crore
April 2025: ₹10 crore with 30-day reporting

The 30-day rule disrupts quarterly batch processes, demanding near-real-time or real-time automation capabilities.
