The per-user price tag tells you little about the final budget. Licences, hosting, implementation and hidden costs: the figures in euros to decide with your eyes open.
In short. As of July 2026, an Odoo Enterprise licence costs €19.90 per user per month on an annual commitment (Standard plan, all applications, Online hosting included) or €29.90 for the Custom plan (Odoo Studio, multi-company, API, on-premise). The licence is only the visible part, though: for a Luxembourg SME, the real budget is decided by implementation, data migration and training. As an order of magnitude, expect €5,000 for a simple scope up to €40,000 and beyond for a multi-module project.
"How much does Odoo cost?" is the first question every business owner asks when comparing ERPs, and the honest answer comes in two parts: the licence price, public and predictable, then the project cost, which depends on your scope. This article gives you both, in euros, with the Luxembourg specifics that change the calculation.
Odoo licence prices in 2026
Odoo offers three plans: a free plan limited to a single application, the Standard plan at €19.90 per user per month (annual billing) with every application on Odoo Online, and the Custom plan at €29.90 which adds Odoo Studio, multi-company, the external API and on-premise or Odoo.sh deployment.
| Plan | Price (annual commitment, excl. VAT) | What it covers |
|---|---|---|
| One App Free | €0 | A single application, unlimited users, Online |
| Standard | €19.90 / user / month | All applications, Online hosting included |
| Custom | €29.90 / user / month | + Studio, multi-company, API, on-premise / Odoo.sh |
Two details that prevent bad surprises. On monthly billing without commitment, Standard rises to €24.90: the annual commitment saves roughly 20%. And only internal users count: clients consulting a portal or paying an invoice cost nothing. A 10-user SME on Standard therefore pays €2,388 per year in licences, everything included on the software side. Prices are quoted excluding VAT, charged at the Luxembourg rate of 17% for a company established in the Grand Duchy.
Hosting: included, with exceptions
On the Standard plan, Odoo Online hosting is included: updates, backups and security are handled by the vendor, with no server to run. Hosting becomes a budget line in two cases. Odoo.sh, the platform for customised databases, is billed on top, depending on the capacity and storage you choose. On-premise costs nothing to Odoo but shifts the server and its administration onto you. For businesses that care about where their data lives, the choice deserves a proper discussion.
Implementation: the real spending line
An ERP is not installed, it is configured. Needs analysis, accounting setup, data migration, testing, training: this is where the budget is decided, and where quotes vary most from one integrator to another. The orders of magnitude we observe on the Luxembourg market:
| Scope | Example | Indicative budget |
|---|---|---|
| Simple | Invoicing + PCN 2020 accounting, services company | €5,000 to €15,000 |
| Intermediate | + CRM, purchasing, inventory, historical data migration | €15,000 to €40,000 |
| Complex | Multi-company, custom development, integrations | beyond €40,000 |
These ranges are indicative: two companies of the same size can have projects varying threefold depending on how clean their data is and how many processes need covering. Be wary of quotes far below the market: the catch-up is billed by the hour, afterwards.
The costs nobody budgets for
Four items come up in every project that overruns. Data migration first: extracting, cleaning and reimporting years of accounting history takes time, especially when the old tool makes it hard. Training next, too often sacrificed even though it decides adoption. Third-party modules as well: some specific needs require paid modules or development, to be priced before signing. And evolutive maintenance: plan on the order of 10 to 20% of the implementation budget per year for adjustments, changes and version upgrades.
Good news on the Luxembourg side: the accounting localisation is included in Odoo. The PCN 2020 standard chart of accounts, VAT returns in the eCDF format and the FAIA audit file export are part of the product, with no paid module. That is a real differentiator against software that bills local compliance as an option, and we covered the setup in our guide to Luxembourg accounting in Odoo.
A worked example: a 10-user SME over 3 years
Take a services company with 10 users, covering CRM, invoicing, accounting and purchasing, with an €18,000 implementation. Over three years: Standard licences €7,164 (€2,388 per year), implementation €18,000, evolutive maintenance around €5,400 (10% per year). A total in the region of €30,500 excluding VAT, or roughly €850 per month smoothed out. Compare that with the combined cost of a local accounting package, a separate CRM, an invoicing tool and the hours spent re-keying data between the three.
How to bring the bill down, without regretting it
Three levers work. Stay standard first: every departure from Odoo's native behaviour is paid for in development and then again at every migration; a good integrator starts by adapting your processes to the tool, not the other way round. Phase the project next: starting with invoicing and accounting, then adding CRM or inventory once the team is comfortable, spreads the investment and secures adoption. Prepare your data last: clean client records and a tidy chart of accounts before the project saves days of billable work. One business owner we supported cut the initial quote by a third simply by cleaning his data internally before kick-off.
