Localizing a software product is improved. A plurality of attributes of a plurality of interface elements according to a specified type of user interface are retrieved. Responsive to user input, one or more countries in which the software product is to be localized are specified. An interface element for the user interface is selected. From the attributes of the selected interface element, it is determined whether the interface element is consistent with the specified countries. If not, an alert on a computer display is displayed, in the event the selected interface element is not consistent with the countries specified by the user. The invention also calculates a cost of localizing the selected interface element, wherein the projected cost of localizing the user interface is incremented with the cost of localizing the selected interface element. An alert for the projected cost of localizing the user interface is displayed on the computer display.
