Services for Companies — TaxFactory

BEHIND TAXFACTORY

WE HAVE SEEN BUSINESSES GROW FROM A DESK AND AN IDEA

The first thing we built together lasted three days. We were 11 and 12, with a garage and a bicycle workshop. We learned what no master’s degree teaches: a business is sustained by the people inside it.

We have been working together for more than 25 years. We have seen businesses grow from one person to teams of dozens. In 2018 we brought the rigour of traditional advisory together with digital agility, and Tax Factory was born.

We built it because when your company grows, the problems change, and you need someone who has been there.

Testimonials

Real stories, concrete results

Real reviews from clients who value clear explanations, fast replies and close treatment.

Lluis Capdevila
Manager, Clínica Vet. Capdevila Company Client since 2005

We have been with Luis and his team for more than 20 years. At one point I tried another advisory firm and did not take long to come back. When you find someone who genuinely gets involved, you do not let them go.

Highlights: More than 20 years — tried another advisor and came back
Alicia Piñero
Cerdanyola Judo Vallès Association Company Client since 2018

It was difficult to find advisors who truly got involved. Managing a non-profit sports association is not simple, and with Guillem and Luis everything becomes easier.

Highlights: Advisors who genuinely get involved
Yessica Escribano
Founder, Yess Clean Company Client since 2024

I set up Yess Clean with few resources and many doubts. Tax Factory has supported me from day one, explaining everything clearly and being there whenever I needed them.

Highlights: Growing together from day one

CO-FOUNDER · TAX AND ACCOUNTING

Guillem Márquez Heredia

The firm’s growth engine

I grew up in my father’s firm. I was a terrible student and lost seven years doing everything except working. At 29 I ended up sweeping a warehouse in San Sebastián for 300 euros a month. That is where I really started learning.

Controls the cash and cares for the team

At 16 he joined Guillem’s father’s firm as an intern. What was meant to be a placement became a 27-year career. He completed two degrees while working. In 2018 he started a business for the first time: he co-founded Tax Factory.

OUR PROCESS

How we work with you from day one

No surprises, no fine print. We show you what happens from the moment you choose us through everyday work.

  1. We assign you a personal advisor

    You are not a number. Your advisor will learn your business and be your direct contact for everything.

    Assigned immediately during business hours

  2. We handle the switch

    If you come from another advisor, we speak with them

    We handle the full transfer. You only need to authorise us by email: we contact your previous advisor and request all documentation.

    MORE ABOUT THE TRANSFER

    We collect all tax, accounting and employment documentation. We check that nothing is missing. If we detect mistakes from your previous advisor, we explain them and quote before touching anything. The timeline depends on the outgoing advisor. We keep pushing.

  3. We show you how we work together

    Your first month is training: working method, deductible expenses for your sector and platform setup. By the end, you know how everything works.

    We always confirm that we have received your question and try to reply on the same day

  4. Your quarterly returns, up to date

    We prepare and file your taxes every quarter. And if you want to sit down and review how your business is doing: in Terrassa, in Valencia or by video call.

    HOW EACH QUARTER WORKS

    We receive your invoices, reconcile the accounting, prepare the forms and file them. If there is anything you should know, we warn you first. You focus on your work.

  5. Fiscal close and plan for next year

    We review the year’s results, detect what can improve and plan your taxation. We explain it so you can make decisions.

    In person in Terrassa/Valencia or online, your choice

    WHY WE DO NOT WAIT UNTIL DECEMBER

    Decisions that affect your business cannot wait until fiscal closing. We review during the year to correct in time and plan investments while you can still act.

OUR COMMITMENT

COMMITMENTS YOU CAN CHECK

No lock-in

If we do not convince you, you leave. No penalty, no minimum period, no excuses.

Same-day response

We confirm your question and reply on the same day. Your advisor, not a bot or a voicemail.

No fine print

Everything each plan includes is written in human language. No asterisks.

Migration included

We handle all paperwork with your previous advisor. No cost, zero admin.

YOUR GROWTH

YOUR BUSINESS CHANGES. YOUR ADVISORY SHOULD TOO

At each stage of your business you need different things. This is the path we will walk together, and the services that activate at each moment.

YOU HAVE JUST STARTED
