uniCenta

uniCenta oPOS is a commercial-grade, open-source Point of Sale (POS) system for retail and hospitality businesses. It offers an alternative to proprietary systems, giving you more control over your software and data without vendor lock-in.

The software is built to handle daily operations for shops, bars, cafes, and restaurants. Key features include:

• Cross-Platform Operation: Install it on Windows, Linux, and Mac OS, or run it directly from a web browser.
• Extensible Modules: Add functionality like digital receipts, remote kitchen displays, and a REST API for connecting to other business tools.
• Integrated Payments: Offers secure card payment integrations designed for UK and EU businesses.

As it's open-source (GPL3 license), you can download and use the core system for free. For the latest releases and direct assistance, a paid support service is available. This model provides flexibility for businesses to start without initial costs.
