Hello,
First of all: Welcome to our comunity and thanks for starting a new translations.
We are from on Spain an I know some bussiness that operate in both Spain and Romania. So in a future we may benefit for your effort.
In order to implement Tryton for a company you will probably need a chart of accounts, that sets all the accounting values. You can configure it yourself by creating the proper values or develop a module that set ups the values as templates. A discussion has been started recently to setup the chart of accounts for Italy, so I will recomend you to read it.
