I've bought VMInvoice for Virtuemart for a company that have a e-commerce site based on VirtueMart.
As VmInvoice does not have the Italian translation file I've create one with all the requested labels.

My installed version is 1.2.1 (Installed a week ago)

As most of the labels remains in Inglish i checked the code to find where the problems is:

I found things like this:

JText::_('Global Configuration')
JText::_('Invoice Extra Fields')

That clearly does not point to any translation constants.

I've also found on the upgrade panel that the vminvoice has changed from 1.2.1 to 1.2.3 in a week.
I suppose to use VMInvoice on a production and eCommerce site but with this bugs and release policy I've a lot of doubts on using it on site where money are involved!!
