We make all our theme translation ready. Each theme has .po file for translation which has to be translated with any plugin you personally like. This file includes all words for translation. Unfortunately we are not able to look through the whole translation process you go and find the step you make wrong. We recommend our customers to use Poedit or Codestyling Localization plugin for this need and follow their detailed instructions provided. So basically it depends on plugins to translate the theme correctly, so make sure you do not miss any step.
