This research explores the relationship that exists between inventory control and the use of technology. A survey was conducted in the city of Guadalajara, Mexico, covering 466 micro-companies. A logit analysis was used to calculate the probability for the micro-companies to implement formal inventory controls. The study found that using technology in micro-companies fosters formal inventory control. This chapter contributes to other management control studies which claim that technology might foster the use of formal inventory controls. Furthermore, this chapter aims to advise practitioners to adopt technology in their business as a way to facilitate the implementation of formal inventory controls.
