As with any location you choose to start a business, doing business in Brazil means finding a location, complying with rules and regulations, paying fees and taxes and being fully licensed to do business in Brazil.
If you are not a native Brazilian then there are many things to consider before jumping into a business plan. Language, legalities, corporation regulations, tax laws and more are all things that you need to figure out before you ever begin looking for a location and suppliers for your business. Take the time to learn about doing business in Brazil before you make a decision. Find a professional company to help you handle the challenges and legalities of starting a new business in a different country and follow their advice. Your business plan should include these things as well as actual business items such as location and supplies. The more prepared you are for the challenges that a startup business faces in any country the better prepared you will be to handle the legalities, fees and regulations of business in Brazil.
