Odoo Community is Odoo's free, open-source edition. Odoo Enterprise is a subscription-based edition built on the same foundation, and it adds extra business features, official support, a mobile app, and easier version upgrades. For a Hungarian SME, the question boils down to this: do the core ERP functions cover you, or do you actually need what Enterprise adds on top?
Let's run through what each edition actually gives you, and at the end I'll give you a quick decision guide built specifically for Hungarian SMEs.
What is Odoo Community?
Odoo Community is Odoo's open-source edition, LGPL-licensed, free to download. It comes with the core modules: CRM, sales, purchasing, inventory, manufacturing, project management, website, e-commerce, and invoicing.
You run it yourself, on your own server or with a hosting provider you choose. There's no Odoo SA support included, and no automatic updates either: that job falls to you or to a development partner. The source code is open, though, so you can customise it as far as your development capacity will take you.
What is Odoo Enterprise?
Enterprise is a paid annual subscription, charged per user. It includes everything Community has, plus the official extras, and Odoo SA support comes with it.
Among the features you only get in Enterprise:
- Odoo Studio: no-code customisation covering fields, views, automations, and custom apps;
- Full accounting: bank synchronisation, statement processing, balance sheet and profit and loss statement, OCR-based invoice scanning;
- Native mobile apps for Android and iOS (Community runs through the browser);
- Document management, electronic signature (Sign), Spreadsheet, Knowledge, and approval workflows;
- VoIP, IoT integration, and extra HR and expense-digitisation modules.
On top of all that, Enterprise brings two big practical advantages: official support, and version upgrades that are genuinely much easier. Odoo Online (SaaS) and Odoo.sh managed hosting are also hosting options for Enterprise.
The main differences, at a glance
The comparison below covers the most common decision factors. Details follow underneath the table.

If I had to sum up the table in one line: Community gives you more freedom and a lighter licensing burden, while Enterprise gives you more ready-made business functionality, official support, and simpler operations and upgrades.
Which edition fits your business?
There's no single right answer here, and I'm not trying to nudge everyone toward one edition. Enterprise is worth the cost when you genuinely need what's in it. If your day-to-day depends on full accounting with bank synchronisation, you want to customise fast with Studio, or the mobile app and official support actually matter to you, that subscription buys real, tangible value.
There are cases, too, where Community is plenty. If you've got your own or a partner's development capacity, the core modules cover what you need, and you run accounting through a separate system or bookkeeper anyway, the open-source edition holds up just fine.
A quick decision guide:
- Lean toward Community if the core modules cover your needs, you have development or partner capacity, and accounting runs through a separate system.
- Lean toward Enterprise if you need full accounting, Studio, the mobile app, official support, or a simpler upgrade path.
- Start with an assessment if you have multiple locations, Hungary-specific processes, NAV requirements or existing systems to integrate. It's worth working out what the solution should look like before choosing an edition.
In practice, for most companies the real question isn't “free vs. paid”. It's how you allocate your resources: to managing and developing the system yourself, or to a subscription and official support. A few factors that help decide:
- Company size and process complexity: the more users, locations, and business processes are in play, the more supported upgrades, support, and predictable operations matter.
- In-house or partner IT: with Community, somebody has to own upgrades and operations.
- Accounting requirements: if you want full accounting inside Odoo itself, that points you toward Enterprise.
- How you customise: no-code with Studio, or through development on Community.
AI in both editions
A good chunk of Odoo's official, built-in AI and automation features, OCR-based invoice processing and certain financial automations among them, are conveniently available in an Enterprise environment.
AI can be built on top of Community too, but there it's typically a custom integration: external models, document processing, customer chat or an internal assistant connected through development work.
In a separate article, I'll cover the specific ways a Hungarian SME can use AI in Odoo today.
A grant-funding consideration
For a digitalisation grant, the official call for proposals always governs what's eligible and in what form, so this isn't something to generalise about. I've written a separate article on supplier accreditation and grant preparation: Accredited supplier status: what it means, and why it can determine the outcome of your grant application
Frequently asked questions
Is Odoo Community really free?
Yes, there's no licence fee for Community. That doesn't mean it's free to run: hosting, operations, upgrades and any development work still cost money.
What's the single biggest practical difference between Community and Enterprise?
It isn't any single module. It's the operating model. Community gives you more freedom, but with it comes more development and operational responsibility. Enterprise gives you more built-in functionality, official support, and a simpler upgrade path.
Can I move from Community to Enterprise later?
Yes. The two run on the same foundation, so switching is entirely possible. It's worth checking beforehand exactly which Enterprise features would make the switch worthwhile for you.
Can Hungarian NAV requirements be handled in both editions?
With the right localisation, configuration, or partner module, both editions can be suitable for meeting Hungarian invoicing and NAV data-reporting requirements. The details depend a great deal on how you work, so it's worth reviewing the options separately for each project.
Which edition do I actually need?
Whichever one covers your real requirements with the least unnecessary cost and effort. If you need full accounting, Studio, mobile or official support, that's Enterprise; if the core modules are enough and you have development capacity, Community is a reasonable starting point.
Do I get support with Community?
Not official Odoo SA support. There's community documentation and forums, and a partner like me can provide operational and development support.
Request a free consultation
If you're deciding which Odoo edition to start with, I'll go through the main decision points with you in a short consultation: user numbers, required modules, accounting, system operations, access to developers, and options for extending the system later.
The goal isn't to push everyone toward Enterprise. It's to make sure you don't build your ERP system on the wrong foundation. If Community is the right call, I'll say so.
