TL;DR for CAs
- E-invoicing is mandatory above the notified aggregate turnover threshold.
- B2B and certain other supplies require IRN generation.
- Non-compliance can invalidate ITC claims for recipients.
What it is
E-invoicing means reporting invoice data to the Invoice Registration Portal (IRP) and obtaining an IRN/QR code.
Who it applies to
Registered persons whose aggregate turnover exceeds the notified limit in any preceding financial year from 2017-18 onwards.
Key provisions
- Applicable documents: invoices, credit/debit notes as notified
- Exemptions for specific categories (e.g., certain SEZ/units as applicable)
- Time of reporting and cancellation windows
Practical tips for CAs
Map ERP to IRP APIs. Reconcile IRN failures daily. Educate clients that printed invoices without QR may be defective.
Common mistakes
Missing credit notes; ignoring branch turnover aggregation; delayed IRN leading to ITC disputes.
