# What actually makes an all-in-one cannabis POS/ERP work long-term? I’m curious how other cannabis retailers evaluate “all-in-one” platforms once they move past the first year of operations. From what we’ve seen over 17+ years in cannabis tech, the biggest difference isn’t flashy features; it’s whether the platform was built inside the cannabis industry, understands compliance from day one, and can grow with the business without pricing operators out as they scale. We’ve watched retailers struggle with stacked tools, surprise fees, and systems that weren’t designed for real-world cannabis workflows. That’s why platforms like Proteus420, built specifically for cannabis retail, inventory, accounting, and compliance, tend to perform better over time, especially at a realistic price point. For those running dispensaries or delivery operations: What mattered most to you after year one: cost, compliance, stability, scalability, or industry expertise? ##### Post Metadata - Net upvotes: 1
