Who is behind it

Paula Lavín Fernández

Chartered economist · Specialist in international taxation and ecommerce

  • Chartered Economist No. 2630 — Association of Economists of Cantabria
  • Master’s in Ecommerce (UNIR, 2023/2024)
  • Registered Tax Agent with the Spanish Tax Agency

I am an economist with more than 5 years of experience in taxation and accounting. During that time I realised something: most advisory firms are built for traditional businesses, but freelancers who sell online face a completely different tax reality — and very few specialists who genuinely understand it.

So I decided to train specifically for it. I took the Master’s in Ecommerce at UNIR because I wanted to be the advisor I would have liked to find if I ran an online business: someone who understands what it means to sell on Amazon, handle EU VAT through OSS or keep the books in Holded.

That is how Ecommerce Asesoría was born. A project of my own, from Cantabria, supporting digital freelancers across Spain entirely online.

I am meticulous with numbers and reliable with deadlines. Every client is a unique case and I treat them as such — no small print, no surprises and full transparency at every step.

My goal is simple: you focus on selling, and I take care of the rest.
