Architecture & Technical Details

Architecture

Modular services around Catalog, Inventory, Suppliers, Orders, Quality, Documents — each owning its domain data and exposing typed contracts.

Normalized 8-domain PostgreSQL model — parts, variants, BOM, stock movements, POs, sales orders, inspections and documents. Every table tenant-scoped.

Security

JWT with rotating refresh tokens, RBAC via has_role RPC, RLS on every public table, encryption at rest and TLS 1.3 in transit.

API Architecture

REST for external integrations (ERP, EDI, eCommerce) and typed server functions for the Parts Manager UI. OpenAPI-first with generated clients.
