The approach to developing “Meu Negócio em Dia” began with a deep understanding of the needs of micro-entrepreneurs. We opted for a user-friendly interface, guiding users through simplified steps to enter and categorize their income and expenses. Analytical functionality was implemented with graphs and visual indicators, offering a clear view of the business's financial health. In addition to financial management, the application incorporated educational resources, providing valuable tips and information to improve the user experience. The integration of forecasting and venture viability tools allowed entrepreneurs to explore future scenarios, make informed decisions and increase the sustainability of their businesses. The app is designed to be accessible to everyone, regardless of their level of finance knowledge.
