It's not clear to me how Odoo works with the commercial/community editions.

As far as I understand:

• there are a lot of providers that offer a cloud-based installation of Odoo, along with their support: you just need to pay the fee and you have a ready-to-use Odoo installation and you don't have to bother with servers, backups, etc...
• instead, one can download the source code from github and self-host the application on his own server, taking care of all the technical aspects but without any fee

So far I tried the second way (just to have a full installation to play with) and I installed it on my Linux server. Great.

After login, I tried to install some modules, for example "invoicing" and "accounting". The first one installed without any problems and works well, but the latter opens the registration page (www . odoo . com / app / accounting) and requires me to insert my data in order to enable it.

I don't understand if I did anything wrong: shouldn't the community version be free and available without registration to third parties? Why should I enter my personal information (even for the free version) like company that automatically leads to a wrong domain or phone number?
