The OpenTHC Point of Sale (POS) is an open-source, web-based retail management system for the licensed cannabis industry. Designed for transparency, it empowers retail dispensaries to maintain compliance with state regulations.

Unlike proprietary, closed-source retail solutions, the OpenTHC POS is community-driven and built on open source principles. Businesses are granted license to self-host the application or opt for a managed solution.

Support Open Source Software

Running a commercial cannabis dispensary requires high reliability, secure automated backups, and 24/7 uptime.

If you do not want to manage your own servers, databases, and API integrations, we offer a fully managed cloud-hosted solution.
