ABSTRACT Purpose: Determine to what extent internal control affects the management of payment to construction company suppliers. Theoretical Framework: Focuses on the importance of streamlining and avoiding delays in payment to suppliers through improving internal control in construction companies, based on COSO 2013 and the theory of Arthur Holmes. Method: A quantitative study of causal correlation type was carried out in a population of less than 50 individuals (38), so that we worked with a list of 38 workers related to the tax management of construction companies, given the small population, all of them. people were included in the study. Results and Discussion: The results obtained reveal a heterogeneous perception of internal control among the workers involved. A minority of consumers (5.3%) value it positively, while a slightly larger group (10.5%) consider it negative. Regarding the management of payment to testers, 73.7% of the participants rated it as regular. These findings suggest the existence of areas of opportunity in the implementation of internal controls, particularly in relation to payment processes. Research Implications: The results of this research highlight the importance of strengthening internal control systems in construction companies, especially with regard to the management of payments to suppliers. Given the dependence of these companies on their suppliers for the acquisition of supplies and services, efficient payment management is a key factor for the success of their projects. Originality: It presents a point of view on the role of construction companies in building efficient payment to suppliers through internal control. Conclusion: Internal control has a significant impact (80.2%) on the management of payment to suppliers of Construction Companies, which supports the formulated hypothesis of the study. It is necessary to encourage the active participation of employees through a clear understanding of their roles in tax management to achieve supplier payment management with efficiency and commitment.
