In short
Odoo is a modular ERP suite (open source) from Belgium with hundreds of apps for nearly every business area. It is billed per user/month (Standard €19.90, Custom €29.90, each monthly), offers a free One-App plan as well as a Community plan, and runs in the cloud or on-premise. Ideal for companies wanting a flexibly extensible, cost-effective overall system.
What is Odoo?
Odoo is modular open-source business software that, as a true full-suite ERP, combines over 40 core applications on a shared data foundation – from CRM, sales and e-commerce through accounting, warehouse and manufacturing (MRP) to project, HR, website and Point of Sale. The solution is developed by Odoo S.A., based in Louvain-la-Neuve, Belgium. Its roots go back to 2005 (then TinyERP or OpenERP), and it has operated under its current name Odoo since 2014.
The core principle is the split into a free, self-hosted Community Edition and the paid Enterprise Edition with support and cloud hosting. The modular structure makes it possible to start small and gradually add applications; via Odoo Studio, custom modules and thousands of apps in the App Store, the system can be extensively adapted. This makes Odoo particularly suited to growing SMEs and mid-market companies looking for an integrated all-in-one suite with high flexibility and a competent implementation partner.
Internationally, Odoo is among the leading open-source full-suite ERPs, backed in DACH by a dense partner network. To be honest, however, it is less deeply localized here than the German market leaders: a fully comprehensive DATEV standard integration is missing, there is no guaranteed German data center region with Odoo Online and Odoo.sh, and version upgrades quickly become effort-intensive with custom adaptations in the annual release cycle. German localization with SKR03/SKR04 as well as native e-invoicing, on the other hand, are available. Project success depends heavily on the chosen partner.
Who is Odoo for?
Growing SMEs and mid-market companies looking for an integrated all-in-one suite with high configurability and a competent implementation partner.
- SMEs/mid-market companies wanting an integrated all-in-one suite instead of isolated solutions
- Companies with IT affinity or a partner for customizations
- Trade and manufacturing businesses with end-to-end processes (shop, warehouse, production)
Less suited for: Firms with deep, highly automated DATEV workflows without add-on modules · Organizations with mandatory German data residency in pure Odoo cloud operation

What does Odoo cost?
What Odoo ultimately costs depends on edition, billing model, add-on modules and implementation effort – the entry price alone says little about the total cost. The overview below makes both transparent.
Entry price
Community free · Enterprise from ~€19.90/user
Community free (self-hosted); Enterprise subscription per user (One App Free/Standard/Custom)
Billing & pricing model
Per user/month: One App Free €0, Standard €19.90/€24.90 (monthly/annual), Custom €29.90/€37.40. A paying user = backend access, portal/external users free. Community Edition free (open source).
Plans & editions
| Plan | Price | Included |
|---|---|---|
| Community | €0 (self-hosted) | Free open-source edition for self-hosting; basic features without official support and without Enterprise apps |
| One App Free | €0 | A single app with an unlimited number of users, hosted on Odoo Online |
| Standard | from €19.90/user/month (annual) | All apps, hosting on Odoo Online, maintenance & support; without Studio, multi-company and external API |
| Custom | from €29.90/user/month (annual) | Like Standard plus Odoo Studio, multi-company, external API as well as hosting choice (Odoo Online, Odoo.sh, on-premise) |
Further cost factors (TCO)
Beyond the subscription, these items determine the total cost – we have compiled them for Odoo:
- Implementation
- Implementation services are not included in the subscription (chargeable separately).
- Add-on modules
- All apps included in Standard/Custom; extra: in-app purchases (SMS, AI invoice recognition, etc.) as well as Odoo.sh hosting for custom code.
- Note
- All paid plans include hosting, maintenance, support and upgrades; Custom additionally includes Studio, multi-company and API access.
Support, contract & operations of Odoo
Whether Odoo proves itself in day-to-day use depends – alongside features and price – heavily on operations, support and the contract model. We have compiled how Odoo is provided, which service levels and support channels apply, under which contract and trial terms you get started, and how far the system scales with your company.
Contract & trial
Before you commit, trial period, term and exit matter: this is how you get started with Odoo – and get out again if in doubt.
- Free trial
- Free trial phase, immediate access without a credit card (duration not explicitly stated).
- Operating model
- Odoo Online (SaaS), Odoo.sh (cloud PaaS) and on-premise (the latter in the Custom plan); Community Edition on-premise/open source.
Support & service levels
In day-to-day operation, how well you get help matters. Odoo supports its customers through these channels, languages and response times.
- Channels
- Unlimited email support, live chat, regional emergency phone numbers and a bug report form; plus e-learning, documentation and certifications.
- Languages
- Email support in English, French, Spanish or Dutch; help pages in many languages (including German).
- Response time / SLA
- No formal SLA; email support Mon–Fri (24/5), live chat response within a few minutes.
- Training
- E-learning platform, tutorials, documentation portal and certifications.
Scalability & limits
An ERP should grow with the company. This is how Odoo behaves with a rising number of users, multiple tenants and at its technical limits.
- Users
- Unlimited users with One App Free; otherwise billing per user with no stated upper limit.
- Tenants
- Multi-tenant capable: multi-company in the Custom plan (several companies in one database).
- Limits
- Odoo Online up to 100 GB storage; for more capacity or custom code, Odoo.sh.
- Growth path
- One App Free → Standard → Custom; hosting upgrade from Odoo Online to Odoo.sh or on-premise.
Odoo in the DACH region
Compliance requirements differ by country – DATEV/GoBD in Germany, FinanzOnline/RKSV in Austria, VAT/QR invoice in Switzerland. This is how Odoo performs across the three markets:
Hosting & data protection
Odoo Online/Odoo.sh on Google Cloud (default region Belgium); guaranteed DE data residency only via on-premise or a DE partner.
DATEV
No fully comprehensive standard integration; DATEV export (ASCII/CSV) with German localization; deeper integration via partner modules.
GoBD
GoBD support via audit-proof document storage; depends on correct setup/partner modules.
E-invoicing (XRechnung / ZUGFeRD)
Native support for XRechnung, ZUGFeRD 2.1, Factur-X and PEPPOL (without add-on plugins).
Language & support
German interface and localization (l10n_de, SKR03/04); support via Odoo and German partners.
Onboarding & implementation
- Duration
- depending on scope, a few weeks to several months
- Partner
- rollout nearly always via a certified Odoo partner; self-implementation only realistic for IT-savvy teams
- Cost
- implementation costs come on top of the license and vary greatly by number of modules and customization
Odoo is almost always rolled out with a partner; duration, costs and the effort for annual version upgrades depend heavily on the degree of customization.
Switching & migrating to Odoo
Initial migration via import tools (CSV/XLSX) and API is quite feasible. The critical part is ongoing version migration: with annual major releases, custom modules must be adapted. Set up German localization (SKR03/04) cleanly before go-live; rollout almost always with a certified partner.
Verdict: is Odoo worth it?
One of the strongest full-suite options for DACH SMEs wanting integrated processes, open-source flexibility and good value for money. The central reservations remain DATEV depth, DE data residency and upgrade maintenance for customizations. Success depends heavily on the partner.
Frequently asked questions about Odoo
How much does Odoo cost?+
The Community Edition is free as a self-hosted open-source variant. The Enterprise Edition is billed per user: the Standard plan is around €19.90/user/month, the Custom plan about €29.90 (including Studio, external API, multi-company and hosting choice). Not included are implementation, custom development and in-app purchases – the real total costs are heavily driven by partner effort (as of 2025/26).
Which companies is Odoo suitable for?+
Odoo fits growing SMEs and mid-market companies from startup to upper mid-market (multi-company) that want an integrated all-in-one suite instead of individual isolated solutions. Trade and manufacturing businesses with end-to-end processes across shop, warehouse and production benefit in particular. A certain IT affinity or a partner for customizations is a prerequisite. It is less suitable for firms with deep, highly automated DATEV workflows without add-on modules.
Is Odoo DATEV-capable and GoBD-compliant?+
Odoo does not offer a fully comprehensive DATEV standard integration out-of-the-box. Available are a DATEV export in ASCII/CSV format via the German localization as well as deeper integrations via partner modules. GoBD requirements are supported via audit-proof document storage, but this depends on correct setup and, where applicable, partner modules. For highly automated DATEV processes, add-on modules should be planned in.
Does Odoo support e-invoicing (XRechnung/ZUGFeRD)?+
Yes, Odoo supports e-invoicing natively and without add-on plugins. It covers XRechnung, ZUGFeRD 2.1, Factur-X as well as sending via PEPPOL, for which native access is integrated. Together with the German localization (l10n_de, SKR03/SKR04), the central requirements for electronic invoice exchange are therefore already met as standard.
Where is the data hosted?+
Odoo Online and Odoo.sh run on Google Cloud with Belgium as the default region, i.e. within the EU. There is, however, no guaranteed German data residency in pure Odoo cloud operation. Anyone who must keep data in a German data center can only achieve this via an on-premise installation or a German hosting partner.
What are the biggest weaknesses of Odoo?+
The most significant point is the upgrade effort: with custom adaptations, the annual major releases are effort-intensive and risky, since custom modules must be adapted each time. In addition, there is the DATEV integration that is not fully available out-of-the-box, the missing guaranteed German data center region in the cloud, and fluctuating support and documentation quality. The real total costs, too, are largely determined by partner effort.
Odoo or an alternative?+
For DACH SMEs, Odoo is among the strongest full-suite options when integrated processes, open-source flexibility and good value for money are the priority. Those who instead require mandatory German data residency in the cloud, deep DATEV automation without add-on modules, or minimal maintenance effort should examine more strongly localized DACH alternatives. The decision depends significantly on the right implementation partner.
