echnological innovation grows by leaps and bounds, becoming a key element in the development of any activity in society today. At the business level, the proper use of technological tools provides a clear competitive advantage over establishments that do not have them, or, failing that, over small businesses that are unable to optimize their use. From the above, the objective of this research is to determine the critical success factors that influence the level of implementation of information technologies within micro and small enterprises in the northeastern region of Mexico. For this reason, a questionnaire was applied to 128 owners and managers, using factor analysis with SPSS version 24 as a statistical analysis tool. The results show that there are seven factors that influence the implementation of technology, among them: i) favorable internal relations, ii) adoption, iii) decision making and iv) cost.
