E-Invoicing · IRN Generation · IRP · GST E-Invoice

E-Invoicing Software IRN generated, ITC secured, returns pre-filled.

End-to-end e-invoicing services and software setup in Mumbai and across India — IRN generation, QR code integration, ERP and billing software configuration, bulk e-invoice generation, e-invoice amendment and cancellation, and IRP API integration for B2B and export transactions.

E-invoicing under GST is the system of authenticating B2B invoices, debit notes, and credit notes on the Invoice Registration Portal (IRP) before they are issued to the buyer. Once authenticated, the IRP assigns a unique Invoice Reference Number (IRN) and generates a QR code that must be printed on every invoice. The authenticated invoice data flows automatically to GSTR-1, eliminating manual data entry and reconciliation errors.

E-invoicing is currently mandatory for registered taxpayers whose aggregate turnover in any preceding financial year from 2017-18 onwards exceeds Rs 5 crore. The applicability threshold has progressively reduced and is expected to extend to smaller taxpayers. E-commerce operators, insurance companies, banking and financial institutions, and notified categories are exempt, though the list changes periodically by notification.

Our e-invoicing practice covers applicability assessment, billing software and ERP readiness review, IRP API integration or web-based generation setup, QR code printing compliance, bulk e-invoice generation for high-volume businesses, amendment and cancellation within the 24-hour window, and reconciliation of IRN-generated invoices with GSTR-1 auto-population. We work with Tally, Busy, Zoho, QuickBooks, SAP, and custom ERP systems to ensure seamless e-invoice compliance.

Frequently Asked Questions

E-invoicing is the system of authenticating B2B invoices on the Invoice Registration Portal (IRP) before they are issued. The IRP assigns a unique IRN and QR code, and the invoice data flows automatically to GSTR-1.

E-invoicing is mandatory for registered taxpayers with aggregate turnover above Rs 5 crore in any preceding financial year from 2017-18 onwards. The threshold is reviewed periodically and is expected to reduce further.

IRN (Invoice Reference Number) is a unique 64-character hash assigned by the IRP to every authenticated invoice. An invoice without an IRN is not a valid GST invoice for a notified taxpayer.

Yes, within 24 hours of IRN generation if the goods have not been delivered or the invoice has not been used. After 24 hours, cancellation is not permitted on the IRP; a credit note must be issued instead.

No. E-invoicing auto-populates certain fields in GSTR-1 but does not replace the GSTR-1 filing obligation. Taxpayers must still review, add any missing invoices, and file GSTR-1 within the due date.
