Odoo open source ERP software

In this article I will introduce Odoo open source ERP software set of software solutions. I will discuss the main responsibilities of any ERP software, and compare Odoo with proprietary ERP software.

ERP stands for Enterprise Resource Planning. It is a software or a set of software solutions. It manages your company and is meant to replace workflows based on paperwork or e-mails. These workflows take place in the ERP instead. This allows for transparency, control, tracking, automatization and much more. At the same time it requires processes to run in alignment with the ERP software. It also requires master data and other data to be setup and maintained.

With the innovations and new technologies the ERP ensures the communication between the company and the other actors such as the suppliers and the customers.

There are two types of ERP, well open-source and proprietary which will be explained in below table.

Open-source ERPProprietary ERP
An open source ERP is a software package. It benefits from a community of contributors who bring lots of improvements quickly and frequently (sometimes more than one significant feature addition or improvement per month).

Open source ERP software is often free, but not always. In the same way, not all free ERP software is open source.

Additions, plug-ins, extensions, special modules etc. may very well come at a fee. The contributors to the open source ERP might be vedors of some of these additions. Contributors may also generate revenue from trainings, consulting etc.
Proprietary ERP software is created by a company specialized in designing and implementing software and computer systems.

Proprietary ERP software licenses are a form of contract in which the ERP software vendor permits a customer to use the ERP software. The license clarifies the permittable and forbidden use of the ERP software. The license also lists the obligations and responsibilities of the customer as well as the vendor.

Often the license fee represents 15% to 25% of the total investment required for ERP implementation projects.

Several open source ERP software solutions are available at the moment. This article focuses on Odoo open source ERP software.
