Overview
GST e-Invoicing is a system where B2B invoices are electronically authenticated by the GST Network through the Invoice Registration Portal (IRP). Each invoice gets a unique Invoice Reference Number (IRN) and a QR code, making it a valid tax document.
Currently mandatory for businesses with turnover exceeding ₹5 crore, e-invoicing ensures real-time reporting of invoices to the GST system, auto-populates GSTR-1, and enables seamless ITC matching. Non-compliance means your invoices are treated as invalid, and your buyers cannot claim ITC.
Big4India helps you set up e-invoicing — from software configuration to IRP integration — and ensures your team is trained to generate compliant e-invoices for every B2B transaction.
