Built for a mid-size textile exporter in Sanganer who processes 80+ export invoices per month manually.
The Problem
Export invoices under India's GST regime require precise data — HSN codes, IGST calculations, shipping bill references, buyer GSTIN validation, and forex rate conversion. Most Jaipur exporters do this in Excel or outdated Tally setups.
The client's accounts team spends 2 hours per day just on invoice generation. Errors are caught at customs, causing shipment delays. One wrong HSN code cost them a 3-day hold at Mundra port and a penalty of ₹15,000.
What We're Building
An AI agent that reads WhatsApp order confirmations and generates GST-compliant export invoices automatically.
- WhatsApp integration — forwards order chats to the bot, extracts buyer, product, quantity, and price
- HSN auto-classification — maps product descriptions to correct 8-digit HSN codes using Claude's reasoning
- Compliance checks — validates GSTIN format, applies correct IGST rate, flags missing fields before submission
- PDF generation — outputs a formatted invoice PDF ready for customs and the buyer
