Doing business in Lisbon is far less bureaucratic than it used to be but can still require a lot of patience, despite the fact that a reasonably good level of English is spoken in business circles. Appointments might stretch on for longer than anticipated, with long lunches common. Even the most rudimentary business transactions and dealings seem to take longer in Lisbon than in most European capitals.

Shaking hands is customary when meeting and taking leave and business cards are exchanged after introduction. When addressing someone, it is customary to use their title (especially if they have a profession (engenheiro, for example) or university degree) followed by their full name. Regardless of their degree, university graduates are usually referred to as 'Doctor(a)'. Mr, Ms and Mrs translate to Sr, Sra and D (for 'Dona'). Co-workers often refer to each other as 'colleague'.

Business suits are standard office attire for both men and women. It is advisable for visitors to enquire whether or not the same attire should be worn for social functions. It can be considered rude to write anything official in red ink. Normal business hours are Monday to Friday 0900-1300 and 1500-1800.

Business socialising generally focuses on eating and drinking in bars and restaurants, with this seldom extending to people's homes. Alcohol will usually be drunk with all meals, although local business people hardly ever overindulge during business meetings.
