The number of buyers in e-commerce is around 1500 million, which represents 63% of Internet users, a percentage that has been growing and taking relevance in all sectors, particularly in the construction industry, which represents 10% of world GDP and 7% of employment, with brick being the product that is most consumed, specifically, the ecological brick is the one that has been gaining importance, due to its low negative impact on the environment. However, the lack of guidelines to facilitate the purchase, factors such as mistrust and the need to see the product, and the timely visualization of sales indicators for management, limit its growth. In this work, EcoBot is proposed, a chatbot with Facebook Messenger to make more attractive and reliable the e-commerce of ecological bricks, in addition, a dashboard on sales indicators, for making quick and timely decisions. A case study in a brick company in Lima shows an increase of 14% of transactions, 15% in sales in the first use of EcoBot, in addition, a survey of 42 customers shows that usability and user experience is very positive.
