Hello Fernando, Sorry we didn't see your request earlier. I'm Project Director at Cadia Consulting. Cadia has been maintaining the localization for NAV for 12 around years, initially in partnership with the Navision company, later as sub-contractor of Microsoft, and since version 2009 this runs under the PLLP - Partner Led Localization Program. We're right now releasing the localization for NAV 2013. The localization covers sales and purchasing with full and automatic calculation and posting of the involved taxes; online electronic invoicing; fiscal reporting including printed and electronic reports (SPED and other) etc.
