At Tryton Spain we would like to improve Tryton ERP system in order to get it working out of the box under the Spain laws.
To reach that there are some law requirements required that should be included into the foundation modules, by now they are into the foundation account_es and many other third modules.
It will be very good that other friends of Tryton take a quick look, may be some many countries have the same constraints, and we can work together in order to evict “localization modules”.
So here I’m gonna to divide them into two sections, those which are legally required and those which will be desirable to have included.
