About us

A bookkeeping office built only for contractors.

Oficina del Contratista was created so construction business owners can stop putting out fires and start seeing their profit. All in Spanish, with people who understand your industry.

Professional Bookkeeping Services
"You run the business, we handle the bookkeeping."

Oficina del Contratista by Armando Ehrenzweig

Our story

Armando Ehrenzweig worked 5 years directly at a construction company and was also a salesman. He knows what it's like to put out fires every day. He is not a contractor: he has been an entrepreneur since 1990 and a business consultant for several business organizations since 2010.

Today he leads Oficina del Contratista, where bookkeeping is paired with business advice so every contractor knows what they earn and makes better decisions.
