How should I organize the website of a company located in different countries.

Hi there!

You can try WPML plugin for this, which helps in running fully multilingual websites with WordPress, making it easy to translate WordPress pages, posts, tags, categories and themes.

Thank you very much @narenin i have one last question if i decided buy 3 different domains for each coutry or sector, and in two of the domains(web pages) have a very similar information because is the same company, can i be affected by the google penalty?
Than you very much! God Bless yoy!

Yes, it can affect the google ranking of your website. Instead of this I suggest you to create sub-domain, please refer to the given link.
