Building a Real-Time ERP System with Next.js and Supabase

## The Challenge A clinic management company needed a real-time ERP system that could handle 50+ concurrent users without breaking a sweat. The existing solution was a clunky desktop app that nobody wanted to use. ## Why Next.js + Supabase I chose Next.js for the frontend because of its server-side rendering capabilities and excellent developer experience. Supabase handled the backend — real-time subscriptions, authentication, and the PostgreSQL database. ### Key Architecture Decisions - **Real-time sync**: Supabase Realtime for live data updates across all connected clients - **Row-level security**: Every table has RLS policies so users only see what they're allowed to - **Server components**: Heavy data fetching happens on the server, keeping the client fast ## The Result The system now handles 50+ concurrent users with sub-second sync. Clinic staff can update patient records, schedule appointments, and generate reports — all in real-time.
