What is Odoo
The open-source ERP and CRM that brings all your company management together.
What is Odoo
Odoo is an open-source business management software (ERP) and CRM, made up of applications that are installed according to what each company needs and that share a single database. With Odoo you run CRM, sales, purchasing, electronic invoicing, accounting, warehouse and inventory, manufacturing, projects and human resources in a single tool, and everything is connected: a sales order moves stock, generates the invoice and shows up in accounting without retyping anything.
Odoo: what it is and what it is used for
Odoo is used to manage the whole company from a single system: attract and follow up customers, sell, buy, control the warehouse, manufacture, invoice, keep the accounts and organize projects and teams. Instead of having one program for accounting, another for the warehouse and spreadsheets for everything else, every department works on the same data and management sees up-to-date information.
The project was born in Belgium in 2005 under the name TinyERP, was renamed OpenERP and adopted its current name in 2014. Today it is developed by Odoo S.A., which according to its own figures has more than 28 million users worldwide, with a network of official partners in charge of implementing it in each country.

Odoo Community vs Enterprise
Odoo comes in two editions. Odoo Community is the open-source edition (LGPLv3 license) and is the foundation of everything. Odoo Enterprise is built on top of Community and adds applications and features under a paid license from Odoo S.A. You can switch from one to the other.
| Odoo Community | Odoo Enterprise | |
|---|---|---|
| License | Open source (LGPLv3), no license cost | Odoo S.A. license, by subscription |
| Applications | The core apps: CRM, sales, purchase, inventory, manufacturing, invoicing, project, maintenance, website… | Everything in Community plus full accounting, Studio, Documents, Sign, Quality, PLM, Helpdesk and Planning, among others |
| Hosting | On your own server or in the cloud of your choice | Odoo Online, Odoo.sh or your own server, depending on the plan |
| Version upgrades | Handled by your team or your partner | Odoo upgrade service included (custom code is adapted separately) |
| Vendor support | No; community support or support from your partner | Functional support from Odoo S.A. included |
Many of the gaps in Community are covered by OCA (Odoo Community Association) modules, for example the AEAT tax forms. At Anubía we implement both editions: Community usually suits companies with few users, clear processes and the capacity to take on technical maintenance with their partner; Enterprise pays off when you need its accounting, its exclusive apps or want Odoo to manage migrations and hosting. We will review it with you in the initial consulting.
Is Odoo free? How much does Odoo cost?
Odoo Community is free in terms of license: you can download and install it without paying Odoo S.A. What does have a cost is the server, the implementation and the maintenance. Odoo Enterprise is paid per user, and Odoo offers these plans:
- One App Free: a single app (plus the ones it depends on) for unlimited users on Odoo Online.
- Standard: all apps on Odoo Online, with a per-user fee.
- Custom: adds Studio, multi-company and external API access, and allows hosting on Odoo.sh or on your own server.
Only internal users who work in Odoo pay; your customers and vendors can use the portal without a license. Prices change frequently, so always check the official Odoo pricing page.
The total cost of a project depends mainly on:
- The number of users and the chosen edition.
- How many areas you implement and in how many phases.
- Data migration from your current system.
- Custom developments and integrations with other software.
- Training and ongoing support.
After analyzing your processes, we prepare a quote tailored to your project of Odoo implementation; ask us for one, no strings attached.
Advantages and disadvantages of Odoo
Advantages
- Everything integrated: data is entered once and the whole company uses it.
- Grows with you: start with two or three apps and expand without changing systems.
- Open source: you do not depend on a single vendor and there is a very active community.
- Adaptable: a lot can be configured without programming and, when needed, it can be custom developed.
- Spanish localization: chart of accounts, taxes, SII and Veri*Factu.
Real disadvantages and limitations
- It is not "install and go": an ERP requires analyzing processes, configuring and training. Without a good implementation, Odoo falls short.
- A new version every year: each version is supported for a limited time, so it is wise to plan the migrations, which cost more the more custom code there is.
- Over-customizing is expensive: it is better to adapt some processes to the standard than to reprogram all of Odoo.
- Some features are only available in Enterprise, and in Community they have to be completed with OCA modules or developments.
- The quality of the result depends heavily on the partner who implements and maintains it.
Is Odoo right for your company? Odoo for SMEs
Odoo is a particularly good fit for SMEs that have grown with several separate programs and spreadsheets and need to organize their information: manufacturers, distributors, service companies, engineering firms and retailers. Also for larger companies and groups with several legal entities and warehouses.
It is probably right for you if:
- You enter the same data in several places and nobody knows which one is correct.
- Your current software does not cover manufacturing, the warehouse or accounting the way you need.
- You want to see sales, stock and cash flow in real time.
- You prefer a system you can expand instead of changing software every few years.
It may not be the right time if you are only looking for a simple invoicing program and do not expect to grow, or if you cannot dedicate your team's time to the implementation.
Companies that use Odoo: from freelancers to multinationals. At Anubía we have implemented it in more than 150 companies; you can see some of them in our clients and read how Texas Controls replaced its custom ERP with Odoo, with 19 areas implemented at once for 100 users.
Odoo versions
Odoo releases one major version a year, usually in the fall, coinciding with its annual event. The most recent is Odoo 20, whose release notes Odoo published in September 2026.
You do not need to upgrade every year, but you should avoid staying on an unsupported version. If you have an old version, we can help you with the Odoo migration and, if you already use it, with the support and the training of your team.

Digitize your business with Anubía and Odoo
At Anubía we carry out Odoo Enterprise and Community implementations. In both cases they can be custom or standard, with the aim of adapting to the needs and requirements of your business.
Implementing an ERP is a complex project that requires joint work by the implementer and the customer and a relationship of trust between them. This relationship should ideally be long-term, with a commitment between the parties, since an ERP must be stable yet alive, continuously improving.
Analysis and Implementation
We carry out a detailed study of your needs and processes, proposing improvements and agreeing on the project scope.
Development
If it is not a standard project, we do custom programming so that Odoo fully adapts to your requirements.
Support
Once the implementation project is finished, we keep supporting you, answering questions, fixing any issues and adding improvements to Odoo.
Training
We run on-site and online training sessions, which can be recorded. They are fully customized sessions so that you are ready to use Odoo independently.
Frequently asked questions about Odoo
Is Odoo free?
The Community edition has no license cost. The Enterprise edition is paid per user, except for the One App Free plan on Odoo Online. In both cases you need to budget for implementation and maintenance.
What is the difference between Odoo Community and Enterprise?
Community is the open-source edition; Enterprise adds exclusive apps and features, managed hosting, vendor support and included version upgrades, under a paid license.
Does Odoo comply with Spanish regulations?
Yes. It includes the Spanish localization with chart of accounts, taxes, SII and Veri*Factu. We have adapted customers to Veri*Factu with Odoo; you can find more details on our page about Veri*Factu.
Can I implement Odoo on my own?
For a single simple app, yes. When several areas, data migration or manufacturing and accounting come into play, an official partner avoids configuration errors that are very costly to fix later.
How long does it take to implement Odoo?
It depends on the number of areas, the data to be migrated and the developments needed. We define it after analyzing your processes, and we usually implement in phases so that your team does not have to change everything at once.
