Introduction: This research article explores the perception of the need to manage a simulation software or tool that allows for the improvement of skills in planning and decision-making from a financial management perspective. Objective: The main goal is to analyze the importance of financial simulation applications that professionals learn to use to improve personal and business finances. Methodology: The research was of a mixed type and approach, with a quasi-experimental design, a descriptive, cross-sectional, and field study scope, and the Delphi method was used. Results: The findings were established through the applied instrument, which was a structured interview with 25 financial experts based on two theoretical variables: the first is software application, and the second is management. Although some applications are used, experts tend to create their own tools to contribute to effective decision-making from basic to advanced levels. Conclusions: Based on this, it is concluded that decision-making by professionals, with or without postgraduate studies, is deeply influenced by their expertise and the effective handling and analysis of results obtained from free software, Excel add-ons, and paid applications, both at the personal and business levels.
