By just installing some of the "Employee's" modules, one can quickly build a very nice Human Resources Management (HRM) system. You can install some Sales modules, where you will have a robust CRM module. In fact, one of the reasons for the name change from OpenERP to Odoo is that Odoo is much more than an ERP.
Basically, Odoo is available in three versions, a Community version (free open-source software), an Enterprise version which has all the functions as a community but also adds some special and professional features and functionalities as well as a support agreement, and the third one is a cloud-hosted version (software-as-a-service (SaaS)). 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.
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.
