Most small shops in India still write bills by hand. Existing software is either too complex (Tally), needs internet (Vyapar), or costs money every month. BillSnap fixes this. BillSnap is a free, offline Windows desktop app that turns any shop PC into a billing counter. The shopkeeper types the customer name, adds items, hits save — and gets a professional PDF cash memo (original + duplicate on one A4 sheet) in under 10 seconds. No internet connection required. Ever. The software handles everything a small shop needs day-to-day: inventory tracking with automatic stock deduction on every sale, low-stock alerts on the dashboard, daily and monthly sales reports, Excel export, and one-click backup and restore. Multiple companies can run from a single installation — useful for a family that owns more than one shop. The codebase is production-tested, fully documented, and ready to ship. Built with FastAPI (Python), React 18, TypeScript, SQLite, and Tauri for the native Windows shell. The entire app installs as a ~50MB .exe with no dependencies — no Python, no Node.js, no setup required for the end user. A 32-page technical book documents every architectural decision, data flow, and bug fix. The buyer gets: full source code (MIT license), the live website (thebillsnap.vercel.app), all documentation, the installer, and a 30-day handover with the founder. Zero liabilities, zero monthly costs, zero subscriptions to inherit.
