PROTEUS420
PROTEUS420 is an all-in-one, compliance-first cannabis ERP and POS platform purpose-built to support licensed cannabis operators from cultivation through consumer. Founded in 2008, PROTEUS420 was one of the first cannabis-specific ERP and POS solutions built to serve the regulated cannabis industry, long before seed-to-sale compliance became mandatory.
For more than 17 years, PROTEUS420 has helped cannabis businesses navigate complex regulations while streamlining daily operations across cultivation, manufacturing, distribution, retail, and delivery. The platform centralizes critical business functions, including POS, inventory management, state compliance reporting, accounting, CRM, loyalty, marketing, employee management, and payments into a single, integrated system.
Designed for highly regulated environments, PROTEUS420 supports real-time inventory tracking, automated compliance reporting (including integrations with METRC and BioTrack), robust audit trails, and detailed financial reporting. Operators gain visibility into margins, costs, and performance without relying on disconnected third-party tools or manual data entry.
Unlike fragmented software stacks, PROTEUS420 consolidates all operational, financial, and customer data within a single secure ecosystem, reducing errors, enhancing compliance confidence, and lowering the total cost of ownership. Built by long-time technology professionals and cannabis industry veterans, the platform is known for its reliability, scalability, and deep understanding of state-by-state regulatory requirements.
PROTEUS420 serves single-location operators, multi-store retailers, vertically integrated enterprises, and multi-state operators (MSOs) seeking a stable, future-proof foundation for growth. With integrated payments, hosting, support, and ongoing innovation, including AI-powered tools, PROTEUS420 delivers peace of mind in an industry where uptime, accuracy, and compliance are critical.
PROTEUS420: One platform. One source of truth. Built for cannabis. Since 2008.
