Overview & Quick Start Guide

SuperGST is an enterprise-grade, cloud-native Shopify application specifically engineered for Indian e-commerce merchants. Operating an online store in India requires strict adherence to Central Goods and Services Tax (CGST), State Goods and Services Tax (SGST), and Integrated Goods and Services Tax (IGST) regulations under Rule 46 of the CGST Rules, 2017.

SuperGST eliminates manual accounting friction by automatically listening to incoming orders, verifying buyer credentials, calculating precise tax distributions, rendering print-ready PDF invoices, and preparing monthly and quarterly GSTR return spreadsheets.

• Automated Dual-Tax Engine: Computes state-wise CGST + SGST for intra-state delivery, or IGST for inter-state shipments, with automatic reverse-calculation for MRP-inclusive items.
• 5-Tier B2B GSTIN Extraction: Captures buyer GST numbers from cart theme extensions, checkout note attributes, order notes, and customer metafields without requiring expensive Shopify Plus checkouts.
• 4 Essential Document Types: Generates official Tax Invoices, Section 34 Credit Notes for refunds, warehouse-ready barcoded Packing Slips, and Pro Forma Invoices for draft orders.
• Instant PDF Delivery: Generates sharp, branded A4 tax documents in under 800ms using a pooled headless Chromium rendering cluster.
• Storefront Customer App Proxy: Enables customers to download their official tax invoices directly from their storefront accounts via secure presigned download links.
• Government-Compliant GSTR-1 & 3B Reports: 7-sheet Excel exports and individual CSV files formatted for the Government GST Portal / Offline Tool / ClearTax / Tally schemas.
