MrPlaztic POS System
MrPlaztic POS System is a comprehensive retail solution designed for small to medium-sized businesses. It streamlines daily operations through a locally hosted environment, ensuring high security and offline reliability. The system manages everything from real-time sales and barcode generation to complex inventory audits using FIFO-style stock batching. With built-in support for thermal receipt printers (XP-80C) and label printers (XP-470B), it provides a seamless hardware integration for modern retail environments.

The Challenge
The primary challenge was building a robust offline-capable system that could handle complex retail logic—such as FIFO (First-In-First-Out) stock managment, refunds, and fractional exchanges—without relying on cloud connectivity, while ensuring data integrity through automated local backups and audit trails.
The Solution
Implemented an Electron-based singleton architecture with an embedded Express server and a local SQLite engine. Developed a custom database schema to handle recursive stock batches and historical audits. The system features an IPC-based hardware communication layer for reliable silent printing and a localized automated backup engine to prevent data loss.
Successfully developed and deployed a reliable, offline-first POS solution that handles high-volume transactions, provides deep financial insights through custom reporting, and simplifies complex stock management with automated batch tracking.
