Kasirku Cloud

Cloud POS & Real-time Multi-outlet Sync System

Kasirku Cloud - Cloud POS & Real-time Multi-outlet Sync System KASIRKU CLOUD POINT OF SALES & INVENTORY

Project Summary

Kasirku Cloud is a modern cashier and retail management ecosystem that connects dozens of store branches into one central dashboard with uninterrupted offline transaction capability.

Challenge

Unstable internet connections in the field often halt branch cashier operations, causing long queues and inconsistent stock levels.

Solution & Technical Architecture

Designing a hybrid offline-first protocol using local IndexedDB on the client side that automatically reconciles data in both directions via WebSocket and Redis once the connection recovers.

Offline-first engine guarantees the cashier can still print receipts and process transactions while offline.
Real-time stock synchronisation across branches with a locking mechanism to prevent overselling.
Live-updated analytics reports for revenue, gross profit, and inventory turnover.
Multi-device support from Android tablets and iPads to conventional cashier PCs.
