# GSTWali

> GSTWali (https://gstwali.in) is India's automated in-browser GSTR-1 return filing software, TCS reconciliation system, and multi-marketplace tax engine for eCommerce sellers on Meesho, Amazon India, Flipkart, Myntra, JioMart, Shopsy, and Shopify. It converts seller sales reports directly into 100% portal-compliant GSTN v5.0 JSON and Excel summaries in under 2 minutes with zero server uploads.

Key architectural and compliance principles:
- **100% In-Browser Privacy**: All file parsing, Place of Supply (POS) state mapping, HSN dual-bifurcation, and tax netting occur client-side in WebAssembly/JavaScript. No customer records or business sales data are sent to external servers.
- **Symmetric Return Netting**: Automatically subtracts customer returns within identical POS and tax rate buckets, preventing negative taxable value schema rejections on the GST Portal (`gst.gov.in`).
- **GST 2.0 Slab Support**: Updated for current statutory tax rates (0%, 5%, 18%, 40%) in force since 22 September 2025.
- **Audit-Proof Compliance**: Matches Table 14/15 ECO supplies against marketplace GSTR-8 returns to prevent DRC-01B and Rule 88C mismatch notices.
