Opening a company
From the idea to the conservatória.
Most of our clients met us the day they decided to start something. This is the road we walk with them.
Stop 01
A conversation
You tell us what you want to do. We tell you what it takes, in plain words.
Stop 02
The right structure
Self-employed, sole-shareholder company or Lda — we compare costs and obligations with you.
Stop 03
The papers
Tax number, statutes, share capital, everything prepared before anyone signs.
Stop 04
The conservatória
Registration day. You don't go alone — we go with you.
Stop 05
Day one onwards
Activity started, books open, first deadlines in the calendar. Then we keep going.
When I needed to open my company I contacted them and didn't think about anything else… they helped me with everything. They even came with me to the conservatória.

Who answers the phone
Mónica and Jorge.
O Contas Perfeitas is a small practice by choice. It is run by a couple — Mónica and Jorge — who opened it as a company in 2019, after years of keeping clients' books.
Our line has always been the same: a partner for your business. That means answering the phone, explaining the tax letter nobody understands, remembering the deadline before you do, and going to the registry office with you when it's time.
Clients stay for years. Some started with us as employees filing their IRS and came back when they opened their own company.

I would give them a 10-star if I could. They are always available, reply to you without delay. They speak very good English. Above all, they are truly patient, professional and friendly — even when you ask them the same question more than once.

Mónica and Jorge are very professional and always made me feel comfortable and safe. They encouraged me to start my career as a business owner and it was the best decision. I'm Spanish and don't speak Portuguese fluently, and even so there were no communication problems.

I'm French and have been a client since my company started. Mónica and Jorge are a very professional couple, always available and — very important — never late. They speak English too, so if you're a foreigner it helps a lot.
