Make the VAT Number Field Label and Description translatable
Many online stores in the world are in several languages (especially when they need this VAT number plugin, which is for sales to different countries in the EU, which happens to be made up of countries which speak different languages) so it is very unfortunate if these field are not translatable. Don't look in Loco Translate or in Polylang String Translations - it is not possible to translate these user input strings. This has been confirmed by the plugin authors. I hope they include the option to translate these strings very soon so that this plugin is actually worth having in an EU woocommerce store.
I totally agree with Jesse Naylor. It would be great if the Vat Number field is a string in WPML. It would even be better if you can make it dependant to the shipping country. The name of a Vat Number is differtent in Germany than in Austria (but they use the same language)
