About Prosperanza

People contract people, not firms

We combine advisory and technology to help small businesses and communities move from informal to formal, and from surviving to growing.

Who We Are

Prosperanza Advisory Group LLC

We came from a simple observation: many small businesses work well, sell, and support families — yet stay outside the formal system for lack of guidance, not ability.

We bring experience in accounting, financial systems, and operations, applied at the real scale of each business. Operating under the brand Prosperanza360, we work in Spanish and English, because our clients think about their finances in one language and file them in another.
