I built StagePOS, a cloud POS system that's completely free with no monthly fees.

The Problem: Small businesses pay $50-200/month for basic POS functionality, often locked into expensive proprietary hardware.

  The Solution:
  - 100% free software
  - Works with any ESC/POS thermal printer
  - Stripe Terminal integration at standard rates (2.7% + $0.05) + platform fee ($0.05) = total(2.7% +$0.10) 
  - Cash payments = zero fees
  - Cloud-based with real-time sync
  - Built with React + Node.js

  Features:
  - Multi-business types (Restaurant, Bar, Karaoke, Retail) 
  - Remote order support
  - Real-time sales reports (X/Z reports)
  - Google OAuth authentication
  - Multi-tenant architecture
  

  Available as:
  - Web: https://stagepos.com
  - Desktop: https://github.com/kyunghoon5/stagepos-desktop 

  The desktop version is Windows-only for now (Electron), but the web version works on any device.

  Why free? I wanted to build something actually useful for small businesses without extracting rent.

  Happy to answer technical questions!
