Monthly closes, a dashboard and a management view for well-informed decisions.
You have several companies, a group, or a level of turnover, headcount or operations that already calls for financial management.
Tax and accounting advice that stays one step ahead
Not sure what you need? We will guide youWe don’t wait until the quarter ends to tell you how much you’ll pay. We plan your tax strategy continuously to avoid cash-flow surprises.
Using dashboards and advanced technology, we turn numbers into a language you understand. You will have a clear view of your business’s profitability.
We are not just another provider: we are part of your structure. We get involved in day-to-day management to bring order, agility and technical insight.
We’re not reactive, we’re proactive
Unlike traditional advisory firms that only file taxes, at ARRA we sit down with you to analyse the numbers. We understand your business, whether ecommerce, real estate or a startup, so that you can make informed day-to-day decisions with full legal certainty.
- We automate processes to gain efficiency and optimise your tax burden.
- We translate regulatory complexity into ideas that you and your team can understand and apply.
- The technical standard of a leading firm, with the agility and personal touch of people who know your business.
Every company arrives different. We apply the same judgement to all of them
A freelancer starting out, an SME that is growing, a group that is reorganising. The starting point changes and so does the solution, but not the approach: putting the numbers in order so they serve decision-making.
A clear view of your business
We organise and connect your information so you understand what is happening and where you are making or losing money.
Structure and control
We define processes, reporting and a solid financial foundation so you can make decisions with confidence, without improvising.
Focus on growth
We don’t stop at the day-to-day: we help you optimise, plan and prepare your business for the next stage.
Some businesses have their own rules
Some sectors have tax rules unlike any other. These are the ones we are asked about most.
You know what we need, when and why
Whatever your size, the method is the same.
Clear onboarding
We tell you what is needed and why before we start, not as we go along.
Organised documentation
Everything in one place, accessible and up to date, without chasing emails.
Calendar under control
You see deadlines coming with time to decide.
Smooth communication
You know who you’re talking to and when you’ll get an answer.
Technology to work better, not to complicate everything
From Bilky, so you always have your documents to hand, to Power BI, to turn your numbers into dashboards. And if you already work with other tools, we adapt to yours.

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
