Executive Summary

The Product: A mobile-first, offline-capable Point of Sale (POS) system designed specifically for high-volume, quick-service food stalls and restaurants (Coto Kota Daeng).

The Goal: To eliminate the manual, error-prone process of calculating orders by hand and implement a digital system to efficiently manage high-volume orders, while still ensuring 100% uptime through offline capabilities.

My Role: Lead Product Manager – Defined product vision, prioritized the backlog, and managed the AI Agent to deliver the end-to-end application development.

Key Impact:

📉 Reduced transaction failure rate to 0% during network outages.

⏱️ Decreased average checkout time by 30%

☁️ Achieved 100% data consistency between local devices and the cloud database.

The Problem Space & User Pain Points

The Context: Quick-service F&B businesses, especially bustling food stalls and local restaurants, require blazing-fast transaction speeds. However, they frequently operate in environments with spotty internet coverage.

User Research & Discovery: Through on-site observations and interviews with cashiers and restaurant owners, we discovered a critical flaw in their existing cloud-based POS systems.

Core Pain Points:

  1. Manual Order Calculation: Staff were taking orders and calculating totals by hand. This manual process caused severe bottlenecks during high-volume rush hours and led to frequent human calculation errors.
  2. The "Spinning Wheel of Death": Standard cloud POS systems failed due to spotty internet. Cashiers were forced back to pen and paper during these outages, ruining daily sales reports.
  3. Receipt Printing Delays: Hand-written kitchen tickets were slow and messy. Staff needed a way to print thermal receipts instantly via Bluetooth to keep up with the high-volume pace.

Problem Statement:

"How might we build a lightweight POS system that allows cashiers to process orders and print receipts instantly, regardless of their internet connectivity status?"

Ideation & Solutions

To eliminate the bottlenecks of manual processing, we needed to digitize the workflow. However, we couldn't rely solely on a standard cloud POS due to frequent internet outages. We hypothesized that a Hybrid Cloud-Based & Offline-First Architecture would provide the reliability of pen-and-paper with the analytical power of the cloud.
