  3. Sectors

    Ecommerce, creators, eSports, and property and rentals: businesses looking for an advisory firm that already understands their model.

  • Ana Villanueva

    An excellent experience with Arra Asesores. They are a professional, committed team, very involved in resolving any contractual or tax matter, always quickly, clearly and with impeccable service. It is very reassuring to know you can count on people who really get involved and always look for the best solution for you. Without doubt, a team you can trust completely and one I will keep recommending.

  • Fran Iniesta

    From the very beginning we knew we had chosen the perfect strategic partner. At Arra Asesores you can see the knowledge, confidence and attention to detail with which they work. They always reply quickly, with effective solutions and, on top of that, with warm and wonderfully friendly service. It is a pleasure to have a team like this.

  • GUILLERMO ALVAREZ CERON

    Always available for everything, they solve any problem that comes up. Very well trained in every aspect of business you can imagine. I have tried several advisory firms and if one thing didn’t go wrong, another did. Arra asesores are a 10 out of 10. I always recommend them.

  • Oscar Mendez

    From the very first day I needed help as a freelancer, the whole team was there to help me with whatever I needed. Later, when I moved to an S.L., they guided me perfectly and it was a relief to have support at that time. We are still working together and I hope we will be for a long time to come.

  • Miguel Ángel Samper

    If you’re reading this review because you’re unsure which advisory firm to choose, you can stop looking, because I don’t think you’ll find one with better service, speed and professionalism. A 10/10 service and highly recommended.

  • Esther C

    Very happy with this firm. I’ve tried several and it’s the first time I feel I’m getting real advice, rather than just having my tax forms filed and that’s it. They always deal with any query very quickly.

  • JD

    Very satisfied with Arra Asesores. Jaime, our adviser, shows exceptional professionalism and has managed our companies’ taxes efficiently and reliably for years. Highly recommended.

  • JOSE ANGEL MEDINA MARTINEZ

    Very happy to have them on the team. Very professional, agile and with excellent technical expertise.

  • Javier Maura

    Fast, professional service. I trust them and recommend them!!

  • Pau Llopis

    A quick, professional team. Very happy.

Frequently asked questions

Any questions?

I have more questions
Can you give me a price before we talk?

We can give you guidance, but to give you a real fee we need to understand your activity, your volume and your obligations. That way we avoid quoting a price that later does not match what you need.

Is there a charge for the initial assessment?

No. You can tell us about your case and we’ll prepare an initial proposal with no obligation.

Am I tied to a minimum term?

We do not require a minimum term to start working together. We want you to stay with us because the service adds value for you, not because you are locked into a contract.

Can I switch from another advisory firm?

Yes. We will tell you what documentation we need to review your situation and will organise the switch as simply as possible.

Does the monthly fee cover all my queries?

It covers the usual queries related to the service you have contracted. If at any point you need a special study or extraordinary work, we will let you know beforehand so you can decide.

Do you work online or in person?

Both: we work remotely with clients throughout Spain and in person at our office in Villaviciosa de Odón, Madrid.

Can you set up my company for me?

Yes. We support you from choosing the type of company through to registration, via the PAE-CIRCE online system, which is free of charge. Your limited company (SL) ready from €400 + VAT, and if you would like advice to get started, there is Launch Plan.

Do you also prepare income tax returns?

Yes, both for freelancers and for individuals.

Where are my documents?

In Bilky, your client area: there you will find your filed tax forms, your reports and your invoices, organised and available whenever you need them.
