I had a really urgent problem in the middle of the summer that I needed to get fixed. I tried contacting a bunch of agencies but they were either unavailable, slow, had terrible service or were crazy expensive (one company quoted me 1000€!). Josep replied to me within 10 minutes and managed to submit my forms on the deadline and all for a great price. He saved my life - 100% recommend!

... desde que encontré a Serapeum, especialmente Josep Navarro, me he dado cuenta que realmente Josep es un gran profesional, no sólo te asesora sinó que con la jurisprudencia correspondiente, te explica en que situación te encuentras. Actualmente, me está llevando de una manera altamente profesional un tema que complicó mi asesor fiscal anterior ...

Since the moment I first contacted the team behind Serapeum, they replied super fast and effectively. My needs were a bit specific but they had no issue in offering me a customized solution through emails and skype calls (since I was based in Malaysia). I can only recommend them and will likely use them in the future.

He utilizado los servicios de esta herramienta novedosa y estoy muy contenta con los resultados. Serapeum me da un servicio profesional y rápido, y además ofrece mucha información para que pueda tener como usuaria un conocimiento completo del asunto que se trate y así poder tomar la decisión que mejor me convenga. 100 % recomendable!

...además de la calidad informativa está el hecho de lo que cuesta, al contactar por primera vez, tuve muchas dudas de si se trataría de gente profesional de verdad pues me costaba confiar en alguien que por 4 Euros me iba a dar una respuesta, cuando en otros lugares pedían y pagué hasta 10 veces más.

... En resumen, unos profesionales como la copa de un pino, resolvieron todas mis dudas, serios, efectivos y con grandes conocimientos en temas relacionados con la administración, en mi caso, con hacienda. Además de todo ello, a unos precios imbatibles. Merece mucho la pena.

Rápidos, eficientes e impecables. Como profesional no residente, me está resultando de gran ayuda contar con Serapeum a la hora de solucionar trámites y resolver dudas administrativas, por no hablar del servicio de gestión; competitivo, transparente y tremendamente eficaz. Muy recomendable.

... Como no residente no existen muchos lugares donde resolver temas fiscales a distancia con tanta profesionalidad y a un buen precio. Sin duda altamente recomendable!

... Rápido, personalizado y todo online; un gran ejemplo además de nuevas tecnologías aplicadas a un campo donde no es tan habitual, como el jurídico. Chapó.
