Executive Summary
Wholesale distributors in South India manage thousands of daily transactions with complex HSN tax slabs, customer credit ledgers, and thermal receipt printing. Techno Bills was built by TS Innovations as a cloud-first, offline-resilient GST billing and inventory solution tailored for wholesale traders.
The Problem
Legacy offline billing desktop software was prone to data loss on hard drive crashes, failed to sync across multiple counter billing terminals, and couldn't automatically compute GST tax breakdowns (CGST/SGST/IGST) for interstate shipments.
Engineering Solution
- Instant GSTIN Lookup API: Auto-populates business name and registered address upon entering a customer's GSTIN.
- Offline-First Web POS: Uses Web Storage and IndexedDB so cashiers can generate invoices even during internet drops, syncing automatically when connectivity resumes.
- 1-Click Thermal Printing: Direct ESC/POS web USB and Bluetooth printing integration for fast 2-inch and 3-inch receipt dispatch.
- Real-Time Credit Ledger: Tracks customer outstanding balances, payment terms, and automated WhatsApp payment reminders.
Business Impact
- Zero Revenue Downtime: Offline billing capability eliminated counter checkout delays.
- 10,000+ Monthly Invoices generated across active merchant accounts.
- 95% Reduction in GST reconciliation errors during monthly GSTR-1 filings.
