Overview

E-Invoice Setup & Compliance for businesses in Tamil Nadu

E-invoicing is mandatory for B2B supplies if your aggregate turnover crosses the prescribed threshold (currently Rs. 5 crore). We help you register on the IRP, set up your billing software for IRN/QR code generation, validate invoice formats and ensure every B2B invoice gets a valid IRN before reporting in GSTR-1.

No matter which district of Tamil Nadu your business operates in — a busy city or a smaller town — GSTNumber makes e-invoice setup & compliance simple. The entire process is online, so you never need to visit an office, and you stay updated at every step.
