Build 'ShelfSync AI'—a $15K/year B2B SaaS + hardware platform combining low-cost ESLs (e.g., $5/tag) with edge AI for dynamic pricing. The platform would: 1) Deploy Raspberry Pi-powered 'Smart Tags' with e-ink displays and edge AI (e.g., 'Price updated: $3.99 → $2.99'); 2) Provide a 'Pricing Dashboard' showing real-time demand signals (e.g., 'Milk: 30% overstock—reduce price by 20%'); 3) Integrate with ERP systems (e.g., Square, Shopify) to auto-update prices; 4) Offer a 'Labor Savings Calculator' showing ROI (e.g., '$4K/month saved'). Target users: Regional grocery chains, hardware stores, and pharmacies.

Mid-market retailers (e.g., grocery chains, hardware stores) face a $10B+ annual loss from manual price updates, labor costs, and dynamic pricing inefficiencies. Electronic Shelf Labels (ESLs) are prohibitively expensive ($50K+ for 100 tags), and surveillance pricing fears deter adoption. Smaller players lack the capital to deploy real-time pricing algorithms like Walmart/Amazon, leading to lost sales (e.g., $2K/month per store) and margin erosion.
