Open Source Point of Sale

Open Source Point of Sale (OSPOS) is a web-based retail management platform built on the CodeIgniter 4 framework. Designed for flexibility and customization, it serves as a robust solution for small to medium-sized businesses that require a self-hosted POS system. The platform handles core retail operations such as inventory tracking, sales logging, and customer management, while offering advanced features like multi-tier taxation, gift card support, and restaurant table management. Because it is open-source, users have the freedom to modify the code to suit specific business requirements, provided they adhere to the MIT license terms, which mandate the retention of the official footer signature. The system is highly modular, supporting various hardware configurations like barcode scanners and receipt printers. While it offers powerful reporting and multi-user permission controls, users should be prepared for a self-managed deployment process, as it requires a PHP and MySQL/MariaDB environment. It is an ideal choice for businesses seeking a cost-effective, community-driven alternative to proprietary SaaS POS systems.
