Executive Summary

Many small Tamil Nadu boutique apparel retailers—part of the ~10M small merchants in India—still rely on paper, fragmented ledgers and ad-hoc WhatsApp messages to manage billing, inventory (size/color SKUs) and GST-compliant invoices, causing stockouts, reconciliation headaches and lost receipts. They need a simple, Tamil-language tool that fits shop workflows, low literacy staff and intermittent connectivity. Build a mobile-first, offline-capable POS and inventory app with a Tamil-first UI focused on apparel features (size/color variants, layaways, simple stock counts), integrated GST e-invoice output and one-tap WhatsApp invoice/receipt delivery plus UPI/payment collection. Price a core subscription in the $60–$120/year range and sell payments, accounting sync and premium support as add-ons to reach a $120 ACV. The timing is attractive: inexpensive 4G smartphones and pervasive WhatsApp use make distribution in tier 2–3 towns feasible, while regulatory pressure for GST-compliant invoicing creates an urgent need—together pointing to an addressable market of ~10M merchants and ~$1.2B revenue potential at $120 ACV. You can stand out with deep Tamil localization, boutique apparel workflows and a WhatsApp-first retention loop that reduces onboarding friction and CAC versus generic POS players. Be upfront that competition is high; success will demand tight product-market fit, low-touch onboarding, local channel partnerships and a clear monetization path beyond basic billing.
