POS Desktop

Tech Stack

• JavaScript
• React
• ElectronJS
• Local DB

Problem

Small retail businesses still run on spreadsheets — products, prices, and stock spread across inconsistent files. They need a single, simple system to manage inventory and process sales.

Solution

A desktop point-of-sale application that centralises product data, stock levels, and a transaction workflow in one admin-style interface designed for daily use.

Features

• Product and category management
• Stock tracking with low-stock awareness
• Pricing and cost fields per product
• Sales / invoice workflow
• Admin-style dashboard for daily operations
• Desktop-first UI optimised for a counter workflow

Architecture

• JavaScript/TypeScript frontend with a desktop-friendly layout
• Local data layer for products, sales, and stock state
• Modular UI with reusable table, form, and modal primitives

What I learned

• Building software for a counter is different from building for a browser tab.
• Inventory state is harder than it looks — race conditions show up fast.
• Boring UI is the right UI when the user is in a hurry.
