Showcase build / Retail, cafés & laundries / Laravel

Kaha

A point of sale that keeps selling offline.

For the business

Before: Sales stop when the internet drops, and credit sales go in a notebook.

The store keeps selling when the internet or power drops, and every credit sale is written down.

For sari-sari stores, cafés, retail and laundries. Each owner turns on only the features they need, sells on a tablet or phone, prints to a Bluetooth receipt printer, and keeps selling when the internet or power drops.

How it's built

  • Every sale saved on the device first, then synced; the server never counts the same sale twice.
  • Pricing written in the browser and on the server, checked against shared test cases.
  • Manager approvals issued as signed tokens.
  • Credit book, tables with a live kitchen screen, claim tickets, reports and end-of-day cash count.
