Our main objective with commercial projects is to interact with the consumer. The establishment needs to get the attention of its target audience. For this, it is important that we have notions of marketing, to create a beautiful, welcoming and attractive space to the point of arousing in people the desire to purchase the product or service offered. As an example, a store needs to be organized and comfortable, so that the consumer wants to consume. In restaurants, cafeterias, bars and cafes, in addition to good food / drink and efficient service, they must have an inviting atmosphere, so that the client feels good in that environment and wants to return.
