TtaKkaa Cashier — Restaurant POS Suite

End-to-end POS for restaurants & cafés: tables, kitchen, inventory, live reports.

Client: TtaKkaa
Launched: 12 May 2024
Live: Website

Project at a glance

We partnered with TtaKkaa to build a modern, end-to-end POS suite for restaurants and cafés — replacing a patchwork of legacy tools with a single fast platform that runs on tablets and dedicated POS hardware.

The challenge

Concurrent peak-hour operations across many tables and channels (dine-in, delivery, takeaway).
Tight Kitchen Display System integration that prevents duplicate orders.
Recipe-level inventory (not just finished products).
Real-time sales reports that let managers retune pricing inside the same day.

What we built

Flutter mobile app that runs on Android, iOS and dedicated POS hardware.
Laravel 11 backend with MySQL + a Redis hot-path layer for live operations.
WebSocket-based realtime sync between cashier, kitchen and admin dashboard.
Local payment gateway integration with thermal-printer receipts.

Outcome: invoice-issue time down 38%; monthly inventory variance under 1.2%.

Highlight features

Interactive table service map with states (free / reserved / occupied).
Multi-tender payments on a single invoice (cash + card + transfer).
End-of-day reports auto-pushed to the owner over WhatsApp.
Multi-branch support from one admin panel.
