POS (Point of Sale) System with Barcode Integration

Overview

The client required a robust POS solution that would streamline the in-store sales process while staying in sync with their online operations. The POS system had to be fast, intuitive, and capable of handling both barcode scanning and manual product selection. The project scope included barcode generation for every product, cart and invoice handling, seamless data sync, and admin-level controls.

Project Challenge

One of the major challenges was developing a barcode-integrated POS system that works accurately with hardware scanners and is optimized for speed during billing operations. The system had to support real-time inventory management, allow bulk operations, and run smoothly on devices used at the physical counters, such as tablets or desktops. Achieving minimal latency and building a user-friendly interface for non-technical store staff were also key requirements.

Design Research

To understand industry standards for POS interfaces, a deep analysis was conducted on existing systems used by retail businesses, especially in jewelry and fashion segments. Emphasis was placed on understanding cashier behavior, billing workflows, product lookup patterns, and discount/tax calculations. The research guided decisions on user interface layout, keyboard navigation support, and product search optimization.

Design Approach

The design followed a modular and minimal approach. The cart interface was made keyboard-accessible for fast interaction. We used a card-based layout for scanned items with subtotal and tax clearly visible. The barcode scan feature was kept always-ready — one scan added the product instantly. Manual search was integrated with auto-complete to support quick lookup by SKU or name. The admin panel was extended to include control over POS users, product availability, and reporting. All modules were built within the Laravel MVC structure to ensure easy maintenance and scalability.
