I need a custom POS system tailored to a busy retail store. Core requirements are: • Real-time inventory management that updates stock levels the moment a sale is completed. • A built-in customer loyalty program (points, rewards, or similar). • Robust sales reporting with daily, weekly, and monthly breakdowns. • Support for two distinct sales-generation flows that we’ll map out together. Your proposal should focus on your experience creating similar retail POS solutions—frameworks used, scale handled, and any success metrics you can share. Once we connect, I’ll provide sample data structures, preferred hardware specs, and the specific logic for the dual sales flows so you can give an accurate timeline.
