Research first

Before building, we studied how Indian cafés already bill: the biggest POS products, what their customers complain about, and the GST, FSSAI and service-charge rules a bill has to follow. That came down to five promises.

  1. A bill can never be deleted quietly.
  2. Billing keeps working offline.
  3. The price on the menu is the price on the bill.
  4. The owner gets a WhatsApp alert when something unusual happens.
  5. Compliance is on by default, not a setting.

What we built

A mobile-first web POS. Counter and table modes, kitchen tickets on the printer, 80 mm thermal receipts, split payments with a UPI QR, and manager-PIN control on cancellations. A bill can only be cancelled or reopened on the same day. The day ends with a close-out, and the owner gets an insights dashboard.

The menu and table plan came from the café itself: five indoor tables and eight outdoor ones.

Outcome

It went live on 12 October 2026 and runs at Simp’s Café under their brand.
