In summary. In Luxembourg, an Odoo implementation for an SME starts at around 1 500 € for a simple project (2 to 3 applications) and most often falls between 1 500 € and 4 500 € for a foundational digitalization. On top of this integration cost comes the Odoo license, billed directly by Odoo (free for a single application, starting at 24,90 €/user/month on the Standard plan, public price May 2026). The price depends on three factors: the number of applications to configure, the number of users, and your industry. Key point for your budget: most Luxembourg integrators bill by the hour, whereas a fixed-package model locks in the cost before the project starts.
Why this question deserves a real answer with actual figures
When a business owner looks up the price of an Odoo project, they mostly find vague "it depends" answers with no figures, or license tables that say nothing about the integration cost — the part that really weighs on the budget. The result: there's no way to tell whether we're talking 1 500 € or 15 000 €.
This article gives real ranges, observed on projects for SMEs and freelancers in Luxembourg, and above all explains how the integrator's billing model changes the final amount — that's where the price gap is decided, far more than on the license.
What makes up the cost of an Odoo project?
The budget for an Odoo project breaks down into two distinct line items that you should always separate in order to compare quotes.
On one side, the Odoo license: the software subscription, paid directly to Odoo. It's free if you use only one app, and switches to a per-user package as soon as you combine several. On the other, the integration: the integrator's service — analyzing your needs, configuring the modules, migrating your data, training your teams. It's this second line item that varies the most from one provider to the next.
A serious integrator always shows you these two amounts separately. Be wary of a quote that lumps the license and the services into a single figure: it becomes impossible to verify what you're really paying for.
How much does the Odoo license itself cost?
The license is billed per user per month and gives access to all applications. A single application remains free for an unlimited number of users. As soon as you activate more than one, you move to the paid plan.
According to Odoo's public pricing reviewed in May 2026, the Standard plan is 24,90 €/user/month (annual commitment) and the Custom plan — which adds Odoo Studio, multi-company support, and the external API — is 49 €/user/month. These rates change regularly and should be verified on odoo.com at the time of quoting. An honest integrator takes no margin on the license: they help you choose the right edition, but Odoo bills you directly.
In practice, for a team of 3 users on the Standard plan, the license comes to about 75 €/month, or 900 €/year—a recurring expense to be distinguished from the integration cost, which is one-time.
How much does the integration cost—the part that makes the difference?
This is where price gaps are widest, because they depend on the integrator's billing model, not just on project complexity.
The Luxembourg market bills overwhelmingly by the hour or by the man-day: the integrator sells a block of hours — often starting at 20 hours, around €130/hour — and then bills every additional hour. On paper, it's reassuring. In practice, the scope shifts, the hours pile up, and the final cost is only known at the end of the project.
Conversely, a fixed-price model sets the amount in the quote, after a scoping phase. The price no longer moves, whatever the actual duration. This is how Advena works, with a three-tier grid: from 1 500 € for a Starter (2-3 modules), from 4 500 € for a Business project (4-6 modules), and an on-quote package for full transformations. For organizations just starting out, a monthly installment plan is also available, from 125 €/month.

Fixed package or hourly billing: what's the real impact on the final bill?
For the same scope, the billing method can make the final cost vary by as much as double. Hourly billing shifts the risk of overruns onto you: if configuration takes longer than expected, you pay the difference. The package shifts that risk onto the integrator.
Two real Advena cases illustrate the gap (amounts excl. VAT, excluding Odoo license).
A retailer in Luxembourg City wanted a Point of Sale (POS) connected to its inventory management. With the Advena package, the project cost 1 600 €, versus 2 700 € estimated by a competitor billing by the hour — for the same scope.
A services company wanted to connect three apps: CRM, invoicing/quotes, and timesheets (tracking time spent per project and per team member). With the Advena package, the project came to 2 400 €, with an option at 200 €/month, where hourly billing would have reached 4 800 €.
In both cases, the difference comes not from the quality of the work but from the business model: by the hour, the meter keeps running; at a fixed price, the cost is locked in advance.
| Project | Scope | Advena package (excl. VAT) | Equivalent billed hourly (excl. VAT) |
|---|---|---|---|
| Retail business, Luxembourg City | POS + inventory management | 1 600 € | 2 700 € |
| Service company | CRM + invoicing/quotes + timesheet | 2 400 € (or 200 €/month) | 4 800 € |
Real Advena cases, amounts anonymized. Odoo license additional, billed by Odoo. The "hourly" amounts reflect an estimate at the prevailing market rate (packs from 20 h, ~130 €/h) and vary by provider.
Which factors push the price up or down?
Three variables determine the integration cost: the number of applications, the number of users, and the industry. Understanding their relative weight helps you frame your budget before you even request a quote.
The number of applications is the first lever. Installing and configuring accounting alone is quick; connecting CRM, sales, invoicing, inventory, and the website into a coherent flow takes more configuration and testing work. Each module added lengthens the configuration phase.
The number of users matters on two fronts: the license (billed per user) and training (more teams to train, more different profiles to support). A 3-person company trains faster than a team of 25 spread across several roles.
The industry determines the complexity of the configuration. A retail business with a point of sale and inventory, a services firm billing by time spent, or a construction company managing job sites don't have the same needs. The more the trade requires specific rules (lots, fiscal positions, multi-currency), the longer the scoping.
A fourth factor, often forgotten: data migration. Importing a clean Excel file is simple; migrating the history of an old ERP, with cleanup and deduplication, is a real undertaking that should be budgeted separately.
How to estimate your own budget: the 4-question method
Before requesting a quote, answer these four questions to find out which range you fall into.
- How many apps will I really use at the start? Aim for the essentials (2 to 3 modules), and expand later if needed. Odoo lets you add modules at the pace of your growth, without rebuilding everything.
- How many users will need access to the software? Count only those who create or edit data. Your customers and suppliers who view their invoices through the portal don't count as paid users.
- Does my industry impose specific rules? Cash register, inventory, job-site tracking, time management: the more specific it is, the heavier the configuration work.
- Do I need to bring over data from a previous tool? A simple Excel import, or a full ERP migration? The answer significantly changes the budget.
With these answers, a starter project with 2-3 modules for a small team usually falls in the lower range (around €1,500), while an established SME connecting 4 to 6 modules with data migration moves closer to the Business tier (from €4,500).
The finance + Odoo angle: why accounting configuration factors into the price
One thing purely technical integrators underestimate: Luxembourg accounting and tax configuration is an integral part of the cost, and getting it scoped wrong proves expensive later. The standardized chart of accounts (PCN), Luxembourg VAT rates, and the FAIA export (the audit format required by the Luxembourg tax authorities) must be configured correctly from the outset.
This is the advantage of an integrator who masters both the tool and local accounting: the tax configuration is handled within the project, not pushed onto your fiduciary, who would discover the errors at year-end close. This dual expertise remains rare in Luxembourg, and it avoids reconfigurations later billed by the hour. configurer la comptabilité luxembourgeoise dans Odoo.
FAQ
What's the minimum budget to get started with Odoo?
Around €1,500 in integration for a Starter project (2-3 modules, standard setup), plus the Odoo license billed by Odoo. If you use only a single app, the license is free.
Is the Odoo license included in the integrator's price?
No, these are two separate things. The license is paid directly to Odoo, per user and per month. A serious integrator doesn't take a margin on it and simply helps you choose the right edition.
Why is a fixed-price package often cheaper than hourly billing?
Because a fixed-price package sets the price before the project starts and shifts the risk of overruns to the integrator. For the same scope, hourly billing can drive up the bill if the project takes longer than expected, as our two cases show (1 600 € vs 2 700 €, 2 400 € vs 4 800 €).
How much does an Odoo project cost for a retail business with POS and inventory?
For a point of sale connected to inventory management, expect from 1 600 € in fixed-price integration, excluding licenses. The exact amount depends on the number of registers, product references and the complexity of your inventory.
Do Odoo licenses increase over time?
Odoo's public rates change periodically. Always check the current pricing on odoo.com at the time of your project. On the Standard plan, expect around 24,90 €/user/month in May 2026 (annual commitment).
In conclusion
The cost of an Odoo implementation in Luxembourg depends on three factors — applications, users, industry — but it's the billing model that makes the most visible difference on your final invoice. A starter project begins at around 1 500 € in integration, on top of which the Odoo license is added. Before signing, insist on a quote that clearly separates license and services, and favor a fixed amount agreed in advance rather than a running meter.
