How We Migrated Our Core ERP Backend to Supabase & Saved 400 Hours

Scaling an ERP platform handling thousands of real-time point-of-sale (POS) transactions across distributed branches requires bulletproof database reliability and instant data propagation.

Why We Choose Supabase & Postgres

Traditional REST APIs with polling overhead caused latency during peak retail checkout hours. By migrating our data layer to Supabase, we tapped directly into Postgres Realtime webhooks and Row Level Security (RLS).

Zero-Compromise Branch Isolation

With custom JWT claims in Supabase Auth, our RLS policies guarantee that warehouse managers in Branch A cannot read or modify inventory records in Branch B, all enforced at the Postgres kernel level without bloating our application layer code.

This migration saved our engineering team over 400 hours of custom authentication and websocket server maintenance.
