Building a Production ERP with Next.js and PostgreSQL
Lessons from shipping multi-module ERP systems — schema design, role-based access, and deployment patterns that survive real business loads.
Enterprise ERP is not a CRUD demo with extra tables. Production systems need strict domain boundaries: inventory, accounting, and sales must share data without corrupting each other's invariants.
We standardize on PostgreSQL with Prisma, explicit transaction boundaries for financial operations, and audit columns on every business-critical row. Next.js App Router handles admin UI; API routes enforce authorization before any mutation.
Deployment uses containerized builds with zero-downtime reloads. The goal is predictable releases: migrations run first, health checks pass, then traffic shifts — the same discipline we apply across DAP ERP, Menuora, and client platforms.
