For a biotech startup registered in Germany I need to set up accounting compatible with German tax authorities. 

Since the startup will need an ERP down the line I want to start with Odoo right away. I want to install on a linux server in a virtual environment which down the line will have to be accessed through the internet since the company will be operating internationally. 

I have had some first contact with odoo about a year ago but wasn't really successful. Back then, however, project management was the main issue to have set up.

Since the company isn't fully financed yet, paid services are no option at the moment but will be down the line.

Here my questions:

Is Odoo a good choice to achieve this? Where can I learn how to do this (I am somewhat familiar with linux, python, postgresql, apache2 and so on).
