Odoo is free, in one specific way, and not in the way most buyers mean when they ask. The Community edition is genuinely free and open source: no license fee, ever, for any number of users. The Enterprise edition, the one most businesses that run their whole operation on Odoo actually use, is paid. Both statements are true at once, and the gap between them is where most “is Odoo free” searches start.
Here is the honest version: what Community includes and what it quietly leaves out, what Enterprise actually costs in 2026, the one plan that really is free with no catch, and how to tell which edition fits a real business rather than which one sounds cheaper on a landing page.
Odoo Community and Odoo Enterprise, in plain terms
Odoo Community is the open-source edition. Anyone can download the code, install it on a server they control, and run it for as many users as they want without paying Odoo a license fee. It covers the core of the business: Sales, basic Inventory, basic Accounting, Purchase, Manufacturing, and more, enough to run real operations on. What it leaves out is the set of apps Odoo reserves for paying customers: Studio, the no-code customization tool; Payroll; full Accounting; and Helpdesk. It also leaves out anything Odoo itself does for you. Nobody at Odoo hosts the database, answers a support ticket, or manages the next version upgrade. That work belongs to whoever runs the system, your own team or a partner you hire.
Odoo Enterprise is the commercial edition, and it is bought under two names: the Standard plan or the Custom plan, both priced per user per month. Enterprise includes the full app set, hosting, official support from Odoo, and a supported upgrade path with every major release. This is what most companies actually mean when they say they “run Odoo,” because it is the edition built to be handled rather than owned.
Community vs Enterprise, side by side
Same comparison, condensed into one table. Read it as two different products built on the same code, not a cheap version and an expensive version of the same thing.
| Odoo Community | Odoo Enterprise | |
|---|---|---|
| License cost | $0, no license fee, ever | $31.10 (Standard) or $61.00 (Custom) per user per month, billed yearly, US pricing |
| Users | Unlimited, at no extra cost | Unlimited, priced per active user |
| Hosting | Self-hosted. You provide and secure the server | Included on Odoo Online, or Odoo.sh and on-premise on Custom |
| App set | Core apps only. No Studio, Payroll, full Accounting, or Helpdesk | Full app set included, 500+ apps |
| Support and upgrades | None from Odoo. Community forums, or a partner you hire | Official Odoo support, plus a supported upgrade path each release |
| Best fit | Developers, prototypes, small self-hosted deployments | A business running real day-to-day operations on the system |
Most of the table is not really about price. It is about who owns the parts of running an ERP that have nothing to do with the license: the server, the patches, the upgrade.
What “free” really costs with Community
Free license is the accurate phrase. Free to run is not, once a business actually depends on the system. Choosing Community moves three ongoing jobs onto your side of the ledger that Enterprise would otherwise absorb.
Hosting. Community has to live somewhere: a cloud server, a company machine, something with an IP address. That machine needs an operating system kept current, a database backed up on a schedule someone actually checks, and enough headroom as data and users grow. None of it is hard in isolation. All of it is ongoing, and none of it is free.
Security patching. Odoo ships security fixes like any serious software does. On Enterprise, Odoo applies them to hosted databases as part of the plan. On Community, self-hosted, applying them is a task on somebody’s list, and a skipped patch is a real exposure, not a theoretical one.
Version upgrades. Odoo ships a new major version every year. Enterprise includes a supported path from one version to the next. Community does not, so moving forward is a project every time: data has to migrate, any custom code has to be checked against the new version, and the result has to be tested before anyone trusts it in production.
None of this makes Community the wrong choice. It makes it a different one: the license is free, and the maintenance is a real, recurring job that has to land somewhere, an internal admin with the time to own it, or a partner running flat-rate Odoo support in the background instead.
The One App Free plan: the real free on-ramp
Separate from Community, Odoo also runs a plan called One App Free, and it is exactly what the name says: one app of your choice, unlimited users, hosted on Odoo Online, for zero dollars. Most people assume this is Community wearing a marketing name. It is not. One App Free actually runs on Odoo’s commercial, Enterprise infrastructure, restricted to a single active app. Odoo hosts it, patches it, and backs it up, the same as a paying Enterprise database, only free while just one app is active.
That makes it the more honest starting point for most small teams, more honest than Community, because there is no hosting to own while you are testing the water. Pick the app that hurts the most right now, commonly CRM or Invoicing, run it free, and the moment a second app gets switched on, the database converts automatically to a paid Standard or Custom plan. Nothing gets rebuilt. The data and setup already in the system carry over as-is.
What Odoo Enterprise costs in 2026
Enterprise pricing is public, and it is simpler than its reputation. Odoo’s own published US price list runs two plans, both billed yearly:
- Standard: $31.10 per user per month. The full app set, hosted on Odoo Online.
- Custom: $61.00 per user per month. Everything in Standard, plus Studio, multi-company support, external API access, and a choice of Odoo.sh or on-premise hosting.
Those two numbers are Odoo’s fees, paid to Odoo directly. They have nothing to do with what an implementation partner charges to set the system up, train a team, or support it once it is live, that is a separate bill entirely, and the two get conflated constantly in “how much does Odoo cost” conversations. Paying monthly instead of yearly costs more per user. The exact math for a given team size, and which of Standard or Custom actually fits, is worked out step by step on our Odoo pricing page.
When Community genuinely makes sense, and when Enterprise is the honest choice
Community earns its keep in a narrower set of situations than the “totally free ERP” pitch suggests. It fits a business with an internal developer, or a technical team, willing to own hosting, security, and upgrades as ongoing work rather than a one-time setup. It fits a genuine prototype, testing whether Odoo’s workflow suits the business before committing budget to a paid plan. It fits a single, narrow internal tool that never touches the core financial or operational data of the company. Outside those cases, the free license usually ends up costing more in unplanned engineering time than the fee it avoided.
Enterprise is the honest choice once real operations run through the system: live accounting, inventory that has to stay accurate, payroll, a support desk, anything where downtime or a broken upgrade is a business problem rather than an inconvenience. It is also the honest choice for a business with no interest in owning server security as a job, which describes most companies outside of software itself. At that point the conversation is not really Community versus Enterprise anymore. It is which plan, and how the rollout gets scoped, and that belongs on our Odoo implementation page, not this one.
Odoo as open source ERP software
Search “open ERP software” and Odoo tops nearly every list, and the label holds up under scrutiny. The Community source code is public, hosted on GitHub, built and reviewed by a large developer community rather than sealed inside one vendor’s private repository. That is what “open source” actually means for an ERP system, and it is a narrower claim than buyers sometimes assume.
Open source is about the code, not the bill. It means the software is inspectable rather than a black box, and portable rather than a one-way door: even a business paying for Enterprise today could, in principle, fall back to self-hosting the Community core if it ever needed to walk away from a hosted arrangement entirely. Try that with a fully closed, proprietary system and there is no equivalent exit, no matter what the sales conversation costs. That distinction, open versus closed at the code level, is a separate question from how Odoo stacks up against one specific closed competitor on features and total cost, which is its own comparison, covered in our Odoo vs NetSuite breakdown.
Open source lowers license cost and lock-in. It does not remove the cost of running the system well. That is the honest answer to “is Odoo free,” in one line.
Frequently asked questions
Is Odoo really free?
Genuinely, in one specific sense. Odoo Community costs nothing, ever, no matter how many users run it, because it is open source and self-hosted. Separately, the One App Free plan is also real: one app, unlimited users, zero dollars, running on Odoo’s own hosted infrastructure. What is not free is Odoo Enterprise, the paid Standard or Custom plan that most businesses running their full operation on Odoo actually use, priced per user per month.
What is the difference between Odoo Community and Enterprise?
Community is the open-source edition: self-hosted, unlimited users, no license fee, missing the Enterprise-only apps like Studio, Payroll, full Accounting, and Helpdesk, and missing Odoo’s own hosting and support. Enterprise is the commercial edition, bought as the Standard or Custom plan, and it adds the full app set, hosting, official support, and a supported yearly upgrade path.
How much does Odoo Enterprise cost?
As of 2026, Odoo’s published US pricing runs Standard at $31.10 per user per month and Custom at $61.00 per user per month, both billed yearly. Those figures are Odoo’s own license fee, separate from whatever an implementation partner charges to set the system up and support it afterward.
Is Odoo open source?
The Community edition is, fully. The source code is public and available for anyone to inspect, modify, and self-host. Enterprise builds commercial apps, hosting, and support on top of that same open core, which is why the paid plans are described as the commercial edition rather than a separate product built from scratch.
Can I run a business on Odoo Community for free?
Technically, yes, and some businesses do, usually with an internal developer willing to own hosting, security patching, and version upgrades as an ongoing responsibility. The license costs nothing. Running it reliably as the operational backbone of an actual business rarely stays free, because that maintenance work still has to get done by somebody.
Which Odoo edition should a small business choose?
Most small businesses do better starting on One App Free, running the single app that hurts the most, then moving to Standard once a second app gets added. Community fits mainly a technical team that wants to self-host and already plans to own the maintenance. For everyone else, meaning most small businesses, Enterprise is the edition built to be run rather than maintained.
Weighing Community against Enterprise for your own business is worth five minutes on a free scoping call, not a guess.
