ERPNext
ERPNext is an open-source ERP — an alternative to NetSuite and SAP Business One — covering accounting, inventory, manufacturing, CRM, HR, and projects, with no license or per-user fees. It is built on the Frappe framework and licensed under GPLv3, and can be self-hosted or run on Frappe Cloud.
- Replaces:
- NetSuite, SAP
- Open source:
- GPLv3
ERPNext in plain terms
ERPNext is developed by Frappe and built on its Python and JavaScript framework. Nearly everything in it is a configurable "doctype", so businesses can add fields, forms, workflows, reports, and whole custom apps without modifying the core — which is what makes upgrades manageable.
A good fit when…
- Small and mid-sized manufacturers, distributors, and service businesses
- Companies where per-user ERP licensing would dominate the software budget
- Businesses that need accounting, inventory, and manufacturing in one system they own
- Operations with processes that need deep customization
Choose something else when…
- Multi-entity enterprises with complex financial consolidation and audit requirements
- Teams expecting an ERP to work without process design — every ERP implementation needs that work, open source or not
What running it involves
- Linux (Debian/Ubuntu officially supported) or macOS
- MariaDB, Python, Node.js, and Redis/Valkey — Frappe v16 lists MariaDB 11.8, Python 3.14, Node.js 24, and Redis 6+
- The bench CLI to manage sites and apps
- wkhtmltopdf (patched Qt build) for PDF generation, and cron for scheduled jobs and backups
Version requirements change between Frappe releases, so we pin them per project. Frappe Cloud removes this work entirely if you prefer managed hosting.
If you’d rather not self-host
Frappe Cloud lists site hosting from $5 per month and dedicated servers from $20 per month, with no per-user fees, as of September 2026.
Requirements and prices are from the project’s own docs and pricing pages as of September 2026 — see sources below.
Deploying and customizing ERPNext
Process design
Chart of accounts, item structure, warehouses, and workflows designed before configuration starts.
Custom doctypes and fields
The records your operation needs, added without forking the core.
Print formats and reports
Invoices, delivery notes, and management reports in the formats you use.
Integrations
Storefronts, payment providers, banks, and shipping connected through ERPNext’s APIs.
Custom Frappe apps
Domain-specific modules built as separate apps that survive upgrades.
Data migration
Items, customers, suppliers, open balances, and inventory migrated and reconciled at a period end.
Migrating to ERPNext
ERP migrations are the most involved of any switch: chart of accounts, opening balances, items, customers, suppliers, open orders, and stock levels all need mapping and reconciliation, ideally cut over at a period end. Historic transactions are usually summarized rather than moved line by line, and rolling out by module reduces risk.
