About OSP
We transform accounting into strategy so companies can grow with clarity, security, and real results.
Our Essence
For nearly 50 years, alongside Haydée Pagotto, we discovered that great companies don't fail from lack of accountants. They fail from lack of strategic tax vision.
OSP was born to change that. We work side by side with leaders who understand that well-planned taxes are protected profits, that strong structure is operational freedom, and that financial clarity accelerates growth.
Every client is a partner. Every decision is a dialogue. Because success only happens when you truly understand the business, and we understand it.
