    In this research, an inventory management system is established for the meat company La Crianza. For the development of the research, the main causes of the deficient inventory management were identified through observation files and surveys of the operators. The main reasons for the problem are that the working methodology in the warehouse is not defined and inventory control systems are not applied. Based on the current diagnosis of the company, activities were established for the application of the 5S methodology in the storage area, inventory policies, processes for requesting, issuing and receiving purchase orders, and criteria were defined for the selection of suppliers. For the development of inventory management policies, the forty meat items sold by the company were taken as a stratified population, the sample was selected through an ABC analysis analyzing the net profit of each product as a classification factor. The result of the analysis showed that nine articles represent 79.80% of the profitability of the company. Weekly sales in 2020 are analyzed from the selected articles, by means of a graphical test carried out in the Minitab software it was determined that the sales of the products conform to a normal distribution with a pvalue> 0.05. Once the normality of the data was verified, periodic review policies were established for each of the items,for the analysis one day was assumed as replacement time and the acquisition frequency established by the company was respected because the products analyzed have a R=reduced shelf life. Indicators were defined to determine the efficiency of the inventory management system, including the duration of the inventory, an indicator that currently exceeds the five days of storage established in the company's policies. It was also determined that 7 of the 12 suppliers that the company has approved with a rating greater than 6/10 the evaluation carried out according to the proposed criteria, the main factor that was analyzed for the rating was the quality of the supplies.
