as far as small entrepreneurial ventures go, there are three types of businesses in Brazil - the Sole Proprietorship (empresário individual), the  Limited Liability Company - llc (empresa individual de responsabilidade limitada - EIRELI), and the Limited Liability Partnership - llp (sociedade limitada).

Regardless of the structure of the business all three share some common factors and requirements.

A business is classified as a Microempresa (Microenterprise) if its annual revenues are less than R$ 360,000.
