This research paper aims to study the contribution of business intelligence (BI) to small and medium-sized enterprises (SMEs) and provides a portrait of BI services for small and medium-sized enterprises. Based on the existing literature, we will try to examine its factual dimension in Morocco. The main objective is to emphasize from the literature review that BI plays an important role in the performance of SMEs. We have proposed a conceptual perspective that allows to understand the concept of BI and SMEs to understand their internal practices in Moroccan SMEs to improve performance. Controlling information is a major challenge faced by businesses, especially small and medium-sized businesses. Information is the decisive key to their differentiation and development, and also the key to their survival in the fierce environment of national and international competition. In addition, understanding the internal and external environment is also essential. On the one hand, SMEs must recognize their strengths and weaknesses and, on the other hand, they must highlight opportunities and threats. Keywords: business intelligence, information, SMEs, performance.
