Odoo vs ERPNext
Odoo against ERPNext for a self-hosted ERP: open-core LGPL Community with a paid Enterprise edition against fully GPL ERPNext, module coverage, hosting and upgrade paths, customization frameworks and support lifecycles.

Comparisons anchored on Odoo, the business suite with an LGPL-3.0 Community edition and a proprietary Enterprise edition: against ERPNext and Dolibarr, and Community against Enterprise.
Odoo against ERPNext for a self-hosted ERP: open-core LGPL Community with a paid Enterprise edition against fully GPL ERPNext, module coverage, hosting and upgrade paths, customization frameworks and support lifecycles.
What the free LGPL Community edition leaves out compared with paid Enterprise: apps such as Studio, full accounting, Documents and Payroll, the upgrade service, mobile apps and support, and how to decide which edition to deploy.
Odoo against Dolibarr for small and mid-sized businesses: a broad Python suite with paid Enterprise apps against a lighter, fully GPL PHP application with optional modules, plus hosting, extensions and upgrade effort.
The three open source ERP options most often shortlisted: licenses and what is paid, module depth (manufacturing, accounting, HR), technology stacks, hosting and partner ecosystems, and which company size each fits.
How the pricing models differ: Odoo's per-user subscriptions and the Custom plan needed for on-premise against ERPNext's free self-hosting and Frappe Cloud plans that do not charge per user, plus implementation and support costs on both.
Manufacturing fit compared: Odoo MRP in Community with PLM, Quality and shop floor tools in Enterprise only, against ERPNext's bills of materials, work orders, job cards and production planning in the free product.
How major version upgrades work on each edition: Odoo's upgrade service for Enterprise subscribers against community tools such as OCA OpenUpgrade, the three-year support window, and the effort custom modules add.
Which on-premise install route to use for Odoo: the official packaged installers, a source install, or the official Docker image. Covers supported platforms, Community and Enterprise availability for each, why the Windows package is not for production, PostgreSQL and Python requirements, and how Enterprise modules fit the Docker image.
Where to run Odoo: Odoo Online for standard apps without custom code, Odoo.sh for custom modules with Odoo-managed branches and backups, or your own servers. Covers which pricing plans allow each option, version and extended support differences, backups, and how to move between them.
Two Python and PostgreSQL ERPs compared: Odoo's LGPL Community plus paid Enterprise apps against Tryton's fully GPL-3.0 modules under a foundation, release and LTS policies, module coverage and the partner ecosystem around each.
A modern app-based ERP against the Java ERP descended from Compiere and ADempiere: licenses (LGPL-3.0 Community versus GPL-2.0), OSGi plugins versus Odoo modules, databases and what each costs to customize.
An end-user ERP suite against an Apache-2.0 Java framework with business applications: out-of-the-box coverage versus build-your-own, release cadence (OFBiz 24.09 feature-frozen) and the development effort each implies.
For buyers who have ruled out a paid Odoo subscription: Odoo Community (LGPL-3.0) against fully open ERPNext (GPL-3.0) on what each free edition includes, upgrade paths without Odoo's upgrade service, hosting, support windows and implementation effort.
Whether Odoo Community plus Odoo Community Association modules can replace an Enterprise subscription: what Enterprise adds, what the OCA provides, upgrade and support trade-offs, and the hidden cost of maintaining community modules yourself.
Running several legal entities in one Odoo database with multi-company versus a database per company: shared records, inter-company transactions, the Custom plan requirement, reporting and access separation, and when separate databases are safer.
What Odoo and Dolibarr cost to run: Odoo's plans and the Custom plan needed for on-premise or Odoo.sh, against free Dolibarr self-hosted or on DoliCloud's published plans, plus implementation, add-ons, hosting and support costs.
The vendors' own managed hosting compared for buyers choosing between Odoo and ERPNext without running servers: Odoo.sh requires the Custom plan, Frappe Cloud publishes site and server prices, plus upgrades, custom code and support cover.
