Cortinex is a GST-compliant billing system and shop sales data management platform. Generate invoices, track inventory, manage shop reports, POS billing, GST returns, and more — built for Indian retail stores, shops, and businesses.
We started building Cortinex Billing after seeing how everyday billing can become unnecessarily complicated for small businesses, with manual invoice creation, scattered records, payment tracking, and software that often feels overloaded with features they don’t actually need.
We wanted to create a simpler, more focused solution that brings customers, invoices, payments, and business records together in one modern, easy-to-use platform. Instead of adding complexity, Cortinex Billing focuses on making everyday billing faster, clearer, and more accessible for growing businesses.
To make it easier for businesses to experience the platform, every new customer gets 6 months completely free for first 500 users.
