smpl_POS — Point of Sale

Overview

smpl_POS is a complete Point of Sale system built by PaphTech using Flask as the backend and MySQL as the database. It features a POS terminal, inventory management, customer tracking, transaction history, dashboard analytics, and store settings — all in a sleek dark-themed UI. The app runs live at /projects/smpl_pos as a Blueprint within the PaphTech platform.

The Problem

Small businesses needed a lightweight, self-hosted POS system that could run on any device without a subscription. Most SaaS POS systems are expensive and lock businesses into proprietary hardware.

The Solution

Built as a Flask Blueprint with MySQL backend, served directly from the PaphTech platform. Zero-install for the end user — just open a browser. Full CRUD for products and customers, atomic checkout transactions, and a real-time dashboard.
