Client Challenge

Local food outlets and chains struggle with expensive, over-engineered POS software. They needed a lightweight system that runs offline, manages kitchen orders, and sends paperless receipts.

Research & Insights

We audited 15 restaurant owners, finding that paper thermal rolls cost over ₹3,000 monthly per station, and system crashes during internet outages caused massive billing backlogs.

Design Process & UX

We built a compact, dual-column billing interface. We structured a high-speed search index so cashiers can search and add menu items in under 3 keystrokes.

Tech Stack Details

Powered by highly optimized Vanilla JavaScript and IndexedDB for local-first offline resilience, styled with clean Tailwind layouts, and integrated with official WhatsApp Business APIs.

Performance Audit

By avoiding heavy frameworks, the entire POS application bundle is under 120KB, launching instantly even on older dual-core terminal computers.

Project Deliverables

  • Unified POS billing with instant receipt generation
  • Live kitchen order display & ticket management
  • Inventory tracking with low-stock alerts
  • Customer loyalty program & WhatsApp receipts

Final Outcome

Thermal paper print costs were cut by 90% via WhatsApp digital billing, order entry speeds increased by 40%, and restaurants continue billing transactions offline during outages.
