When negotiating with Brazilian business people, be aware that they usually think in terms of US dollars. It is important to keep in mind that personal contacts do play an important role in Brazil and can make the difference in doing business deals. Although many Brazilians speak English, some may feel more comfortable in business meetings if an interpreter is present.
Austrade São Paulo recommends that you are accompanied to business meetings by a local contact and that all initial written correspondence with potential business partners be in Portuguese or in English. Avoid using Spanish as a substitute for Portuguese. In business conversations, use titles if any (e.g. Professor, Doctor), and ‘Senhor’ (Mr) or ‘Senhora’ (Mrs). During meetings, use the title ‘Mr’ or ‘Mrs’ and then their first name, not their last name (i.e. Sr Carlos, Sra Julia). They are not very straightforward businesspeople and have a policy of never blatantly saying ‘no’.
