Marketing is an essential function of any business. It is not mere sales. It starts before production and helps you understand what you should produce depending on the market demand and condition. It will also answer how to create and what to produce and deliver. How to distribute and sell, how to take the message about your product to the target audiences, what should be your price, whether your customer is happy or not, and if they are not pleased with what you should do. These principles are true to you to sell yourself as a professional and even for non-profit organisations to reach their audiences and achieve the expected millage.
