One of the essential processes, implemented in an entity with the purpose of providing a high degree of security regarding the achievement of its proposed goals, is internal control. Such control plays a pivotal role in the administrative-accounting machinery in the business sector. Hence, the objective was to determine the correlation between inventory internal control and the performance management of a commercial emporium in the San Martin region of Peru. To this end, a quantitative study with a non-experimental, correlational, and cross-sectional design was undertaken. As a result, through correlation examination using the Spearman's Rho method, it was found that there is a significant relationship derived from the control of product reception with performance management. Likewise, it is evident that inventory internal control has an indissoluble link with the performance management of businesses in the commercial emporium of that region.
