ERPNext — Open Source ERP for Growing Businesses

Introduction

ERPNext is a free, open-source enterprise resource planning system built on the Frappe web framework. It provides modules for accounting, inventory, manufacturing, HR, CRM, and project management, making it a complete back-office solution for small and mid-sized businesses without the licensing costs of proprietary ERPs.

What ERPNext Does

• Manages full double-entry accounting with multi-currency and multi-company support
• Tracks inventory across warehouses with batch and serial number management
• Handles manufacturing workflows including BOM, work orders, and production planning
• Runs HR operations from recruitment and onboarding to payroll and leave management
• Provides CRM with lead tracking, opportunity pipeline, and quotation generation

Architecture Overview

ERPNext runs on the Frappe framework, a full-stack Python web framework using MariaDB or PostgreSQL for storage and Redis for caching and real-time updates. The frontend uses a custom JavaScript framework with REST and WebSocket APIs. Background jobs run through a Redis-backed worker queue, and the Bench CLI manages sites, apps, and deployments.
