GST India Premium Suite handles IRP e-invoice registration with IRN and QR code, e-way bill generation from deliveries, and GSTR-1/3B return preparation worksheets from your ERP data. For Indian businesses above the e-invoicing turnover threshold and exporters who need e-invoice, e-way bill, and return prep working together rather than as three disconnected free modules. Planned features include automatic IRN generation and cancellation, distance-aware e-way bill creation, HSN summary validation, GSTR-1 and GSTR-3B preparation exports, reconciliation views against GSTR-2B for input credit, and multi-GSTIN support for businesses registered in several states. This app is currently in development on the ECOSIRE build pipeline. It will ship first for Odoo 17, 18, and 19 simultaneously, with an ERPNext port following on the v15/v16 track — the same triple-version coverage as every live ECOSIRE app. One-time license, free updates within your major version.
