This research was developed in a dairy company, with the purpose of providing tools that allow the continuous improvement of supplies necessary for daily production, to ensure the quality of the finished product and customer satisfaction. A Case study was carried out in the dairy company in Cayambe, Ecuador. In order to determine the supply management model, a survey was applied to identify the deficiencies and weaknesses that directly affect the management system within the company. With the help of the management the historical data of 3 years for the classification of the inputs was collected through the ABC method, giving a total of 45 inputs and a total cost of  USD 126,351.54, within this group of inputs 8 types of yogurt containers were found. Using the FORECAST PRO TRAC software, the best forecast models were determined. Through the forecast, the variability coefficient (CV) was calculated, an indicator that allows us to choose the inventory management model to be used; obtaining as a result the use of the EOQ model. With the application of this model, it has reached the decrease of orders per month and reducing supply costs.
