Open Source Point of Sale (OSPOS)

Open Source Point of Sale (OSPOS) is a web-based point of sale application for running sales, managing inventory, and tracking customers and suppliers. It is designed for small to medium retail and hospitality workflows and includes reporting and operational tools.

Key Features

• Sales register with transaction logging
• Inventory and stock management for items and kits, including extensible attributes
• Customer and supplier database
• Quotations and invoicing, plus receipt/invoice printing and email delivery
• Multi-tier taxes (VAT/GST) and configurable taxation rules
• Receivings and expense logging
• Gift cards and rewards/loyalty support
• Role-based multi-user access and permission control
• Reporting for sales, orders, expenses, and inventory status
• Barcode generation and printing

Use Cases

• Retail store POS for daily checkout, receipts, and inventory tracking
• Small business invoicing/quotations with customer management
• Basic restaurant operation workflows (for example, table handling) with sales reporting

Limitations and Considerations

• License requires the built-in footer signature to remain visible and unmodified on every page
• Hardware compatibility (printers, scanners) depends on environment and supported device setup

OSPOS is a practical choice for organizations that want a browser-based POS with inventory, invoicing, and reporting in one system. It can be deployed on standard PHP and MySQL/MariaDB infrastructure and customized to fit common retail workflows.
