## Overview

Manufacturing ERP for Indian manufacturers, organized as a React client and a FastAPI modular monolith. The user-facing flow spans customer and catalog records, order intake and prioritization, factory planning, invoice review, and the broader purchasing, production, billing, and finance capabilities documented in the README. The planning engine is a distinct scheduling layer. Source excerpts are partial, so several documented domains appear without inferred runtime links; the API’s router registration and selected service calls are shown where supported.

Main entry points: [`backend/app/main.py`](https://github.com/erpro272/originial_erp/blob/claude/sweet-thompson-f1hjgv/backend/app/main.py) (FastAPI application), [`frontend/src/app/App.tsx`](https://github.com/erpro272/originial_erp/blob/claude/sweet-thompson-f1hjgv/frontend/src/app/App.tsx) (ERP web app), [`backend/app/invoices/service.py`](https://github.com/erpro272/originial_erp/blob/claude/sweet-thompson-f1hjgv/backend/app/invoices/service.py) (Invoice processing), [`backend/app/core/storage.py`](https://github.com/erpro272/originial_erp/blob/claude/sweet-thompson-f1hjgv/backend/app/core/storage.py) (Encrypted file storage)
