A single software to manage a company’s sales, invoicing, accounting, stock, e-commerce site and HR: this is the promise ofOdoo. This Belgian open source ERP claims nearly 15 million users in the world and has just been valued at more than 7 billion euros early 2026. Suffice to say that he no longer plays in the league of outsiders.
But does such a sprawling tool really keep its promises for a French VSE or SME? I installed it, took charge module by module in its demo version, and scrutinized my methodology. Here’s my full review of Odoo: what it’s worth, how much it really costs, and who it’s made for.
Odoo in 90 seconds

- 💶 Price : a free app for life, then €19.90 excluding VAT per user per month for the rest (annual commitment).
- 🏆 Positioning : the most complete all-in-one ERP on the market, open source and European.
- ✅ Recommended for : growing companies that activate their modules as their needs change.
Presentation of Odoo
The story begins in 2002 in a student room in Louvain-la-Neuve, Belgium. Fabien Pinckaers launches a small management software called TinyERP. The project becomes OpenERP, then takes its current name, Odoowhen it goes beyond simple ERP to cover CRM, marketing, website or e-commerce.

Twenty years later, the trajectory is dizzying. Odoo employs approximately 7,000 peoplegrows by almost 40% per year and aims for one billion euros in revenue in 2027. At the end of 2024, a 500 million euro operation led by CapitalG (Google) and Sequoia brings it into the unicorn club. In January 2026, a secondary round led by AXA Venture Partners and Alkeon brings its valuation to more than 7 billion euros. Notable fact for an actor of this size: Fabien Pinckaers remains the main shareholder and repeats that he does not want to go public or sell.
Odoo’s DNA isopen source. The software exists in two editions. The version Community is free, open source and self-hosted. The version Enterprise adds advanced modules, official support and cloud hosting, for a per-user subscription. This dual nature explains a good part of its adoption: you can audit the code, host it wherever you want, and only pay if you need the managed services.
Who is Odoo for?
Odoo aims above all to VSEs, SMEs and ETIs in digital transformation, as well as growing startups. Its modular logic fits well with these profiles: we start with one brick, then we activate others gradually.
- VSEs, independents, associations : the free plan of a single application is often sufficient, for example for invoicing or CRM.
- SMEs : this is the core target. We combine sales, accounting, purchasing, stock and sometimes e-commerce in the same environment, without double entry.
- ETI : Odoo holds its own with multi-company management, the external API and dedicated Odoo.sh hosting, provided you accept dependence on an integrator.
There remains a fundamental question: Community or Enterprise ? The Community version, free, is aimed at structures which have internal technical skills and want to master everything, including hosting. The Enterprise version, paid, targets the majority of SMEs who prefer official support, automatic updates and advanced modules without devoting a technical team. Your choice depends above all on your budget and your internal resources.
On the other hand, if you are a very large company with heavy processes, Odoo will show its limits compared to SAP S/4HANA or Microsoft Dynamics. And if your need comes down to simple invoicing, the richness of the tool risks burdening you more than anything else. If you are comparing several solutions, I invite you to consult my comparison of best ERP software.
Main features
Odoo boasts more than 30 official integrated applications, complemented by thousands of community modules. They all share a single databasewhich avoids having to re-enter information from one module to another. Here are the bricks that I tested and that you will use the most.
CRM and sales management
The CRM module offers a visual pipeline in kanban where we slide opportunities from one stage to another, from “New” to “Won”. It includes revenue forecasting, automated reminders, lead scoring and commercial reporting. It’s fluid and readable, even for a team new to CRM. To go further on this specific module, I wrote a dedicated guide for structure your customer relationship with Odoo.

Sales and quotes
The Sales module transforms a quote into a purchase order, then into an invoice, in just a few clicks. The quote list displays the customer, seller, amount and status of each deal at a glance. Conditions of sale, discounts and payment reminders are managed automatically, and everything is synchronized with stock and accounting without re-entry.

Accounting and invoicing
It is often the front door. The module manages quotes, customer and supplier invoices, bank reconciliation, VAT and financial reports. The accounting dashboard gives a clear view of sales to be validated, overdue payments and bank balance. Automatic reading of invoices by AI saves real time on entry.

Inventory and purchasing
For those who manage stock, Odoo tracks receipts, delivery notes, transfers between warehouses and replenishment in real time. The stock overview shows at a glance what remains to be received, delivered and manufactured. Coupled with the Purchasing module, it automates supplier orders as soon as a threshold is reached.

Website, e-commerce and the rest
Odoo integrates a website editor drag and drop, an e-commerce store natively connected to stock and accounting, a point of sale, electronic signature, project management, email marketing and an HR module with payroll depending on the country. The point is not to have the best tool in each category, but to see everything communicate without going through third-party connectors.
Odoo prices
Pricing is done per user per monthregardless of the number of activated modules. Here are the prices for France (excl. VAT), in annual commitment.
- A Free App : €0. One app, unlimited users, Odoo Online hosting. Ideal for invoicing or CRM alone.
- Standard : €19.90 excluding tax per user and per month (€24.90 monthly). All applications, on Odoo Online.
- Custom : €29.90 excluding VAT per user per month (€37.40 monthly). All apps, plus Odoo Studio, multi-company, external API and Odoo.sh or on-premise hosting.
- Community : free. The open source version to host and maintain yourself, without official support or Studio.

A point of vigilance that I would like to emphasize: the actual cost often exceeds the displayed price. Odoo.sh dedicated hosting is billed in addition to the license, and customizations almost always go through an integrator. On a structured SME project, the implementation budget frequently weighs more than the subscription itself. To be included from the start in your calculations.
Advantages and disadvantages
After getting started, here is what I remember.
The strong points:
- Unbeatable functional coverage : few solutions cover so many professions in a single tool.
- Modularity : you only activate what you need, without paying per module.
- Features/price ratio : the entire suite for a single price per user, with a true free plan.
- Open source and European : auditable code, controllable hosting, Belgian publisher subject to the GDPR.
- Huge ecosystem : API, thousands of community modules, Zapier and Make integrations.
The limits:
- Total cost difficult to read : between Odoo.sh and the integration, the final bill often surprises.
- Dependence on an integrator as soon as needs go beyond the standard.
- Heavy version migrationsespecially with community modules or a lot of customization.
- Uneven quality community modules.
- Learning curve real: the richness of the tool has the downside of getting started which requires time.
Customer reviews on Odoo and D-Score Digitiz
User feedback is shared. On TrustpilotOdoo displays approximately 3.3 out of 5 for nearly 1,000 reviews, a rating which mainly focuses on failed implementation experiences. On Capterramore buyer oriented, the rating climbs to 4.2 out of 5 for more than 1,200 reviews. On G2it revolves around 4 out of 5. The truth lies between the two: a powerful product, but whose success depends a lot on the quality of the implementation.
On the security and data side, Odoo ticks boxes that matter for a European company. The open source code is auditable, hosting can be done on its own or on Odoo.sh, backups are daily and spread across two continents, and compliance GDPR relies on a Belgian publisher. A real argument for sovereignty in the face of American consequences.
I applied my in-house methodology to Odoo, the D-Score Digitiza weighted average of 7 pillars.
| Pillar | Weight | Note |
|---|---|---|
| Features | 25% | 9/10 |
| User experience | 20% | 7/10 |
| Satisfaction and reputation | 15% | 6.5/10 |
| Ecosystem and integrations | 10% | 8.5/10 |
| Sovereignty and security | 10% | 8.5/10 |
| Value/price ratio | 10% | 7.5/10 |
| Product dynamics | 10% | 8/10 |
Digitiz D-Score: 7.9/10. A very good score, which rewards exceptional functional coverage and an ecosystem, tempered by an experience that requires support and clarity of costs that can be improved. Assessment carried out in July 2026.
Alternatives to Odoo
Odoo is not the only option, and depending on your profile another solution may work better. Here are the main alternatives I recommend looking into.
- Dolibarr : French open source ERP, simpler and lighter. Perfect for a small business with basic needs.
- Axonaut : all-in-one French solution (invoicing, CRM, cash flow), designed for VSEs/SMEs who want plug and play.
- Wise : the reference on advanced accounting and French compliance.
- Cegid : Very verticalized French ERP, strong on sectoral business functions.
- Zoho : versatile and inexpensive cloud suite, a little shallower on the stock and production side.
- SAP Business One : robust for industrial SMEs with complex processes, but heavier to deploy.

My final opinion on Odoo
Odoo is one of the rare software programs capable of running almost an entire company from a single interface, without multiplying subscriptions or connectors. Its functional coverage, its European open source model and its functionality/price ratio make it a solid choice for a growing SME.
Just keep in mind that power has a price: that of getting started and, above all, an implementation budget to anticipate. If you have the resources to support it, or a good integrator, Odoo will support you for a long time. To make up your own mind, the easiest way is to test the free version.
