No es fácil elegir cuando hay una gran variedad de opciones al alcance. En el área de asesoramiento fiscal, contabilidad y ámbito laboral son muchas las gestorías con las que uno puede elegir trabajar. En nuestro caso, necesitábamos el mejor nivel de profesionalidad y seriedad en el trabajo a través de un trato cercano y totalmente personalizado a nuestras necesidades: una startup con operaciones internacionales. Asimismo, el nivel de formación de sus profesionales y actualización a nuevas normativas era un aspecto importante. Muy satisfecho con el equipo de profesionales de Xterna con quién he tenido el placer de trabajar y seguiremos trabajando.
