How does Odoo work?
The complete ERP system is based on the concept of apps. Each app maps an essential business process, e.g. CRM, sales, purchasing and warehouse. You only install the apps you need.
Modular structure
Odoo's modular design allows you to select only the functions you need for your business. You don't need to install any other apps. This leaves your menu clear and you do not need to update any data in apps that you do not need at all. The apps on your smartphone are a good comparison.
Main Apps
Odoo offers 40 main apps that cover the most common business processes in a standard chosen by Odoo. With these apps, some of the processes in the company can be easily mapped in many cases. Due to the large number of main apps, Odoo is attractive to many different industries.
Additional Modules
It is not possible for every company to adapt to the Odoo standard. Here are the add-ons: Choose from several thousand modules to meet your specific requirements. If there is nothing for you in this fund, it is no problem to develop the missing functionalities together with a partner due to the open-source code of Odoo.
Integration
The various apps from Odoo are fully integrated with each other. This means that you don't necessarily need to change the app if you have completed one step and want to do the next one. Example: After confirming an offer, you can create the invoice directly from the offer.
Odoo in Germany

Odoo ERP not only offers an innovative and license-free open-source solution, but also a comprehensive German localization. Thanks to the work of the Odoo Community Association (OCA) and many committed developers, the software is fully available in the German language. The German user interface offers intuitive and efficient operation, which is suitable for every employee.
GoBD Compliant
Compliance with the guidelines for proper accounting and data access is no problem with Odoo. As GoBD-compliant software, Odoo can grant the required Z1, Z2 and Z3 accesses as well as create Z receipts and X receipts in the PoS system during a tax audit.
DATEV-Export
Also important for German companies: the DATEV export. To round off the financial accounting and hand it over to the tax consultant, Odoo also offers the option of making a DATEV export. The exports are available in ASCII and XML formats.
TSE
If you use a PoS system, it is also mandatory in Germany for electronic PoS systems to have a technical security device (TSE). Odoo has a cloud-based TSE that guarantees the immutability and seamless recording of all transactions.
Accounting with Odoo
One factor that previously prevented companies from using Odoo was that they could not handle their entire accounting in Odoo. Those days are over. Even with the open-source community edition, it is now possible to do all your accounting in Odoo.

Enterprise vs. Community
Odoo is not equal to Odoo. You can choose between two different editions: the license-free Community Edition and the licensed Enterprise Edition.
However, the license costs are not the only thing that distinguishes the two editions from each other.
In the Enterprise Edition, for example, there is an app for complete financial accounting, while in the Community Edition you have to combine different apps to get the same or even more extensive functionality.
You can find a complete comparison of the functions in our blog post.
How much does Odoo cost?
Enterprise
If you select the Enterprise Edition, license fees will be charged. If you only need a single app, you can also get Odoo for free. With the two other available rates, you get access to all apps and have to choose between the hosting variants.
Community
The Odoo Community Edition is completely free and you do not have to pay license fees. In theory, you can easily download the Community Edition on Odoo.com. However, due to the complexity of the ERP system, we always recommend professional advice from a qualified partner like us.
