By just installing some of the "Employee's" modules, one can quickly build a very nice Human Resources Management (HRM) system. Install a few of the Sales modules and now you have a CRM. In fact, one of the reasons for the name change from OpenERP to Odoo is that Odoo is much more than an ERP.
Odoo is available in three formats including a Community version which is available as free open source, a Professional version which has the exact same features and functions and also includes a professional support agreement, and a cloud hosted version available as a software-as-a-service (SaaS) offering. The cloud version allows a beginner to get up and running on Odoo fairly quickly and at relatively low upfront cost and allows supported modules to be added, but like most other SaaS offerings, doesn't provide the ability to modify any of the code so customization is limited.
Odoo includes the following modules that may be installed with a simple mouse click:
Accounting Human Resource Management (HRM)
Customer Relationship Management (CRM) Content Management (CMS)
Warehouse Management Document Management
Manufacturing Resource Planning (MRP) Fleet Management
Purchase Management Point of Sale (POS)
Project/Service Management Application Builder
In addition, Odoo makes it extremely easy to customize and modify the base functionality with little-to-no programming required.
