The convenience store sector plays a crucial role in the global economy, including in Latin America and Peru. Previous studies have demonstrated the relationship between convenience store density and dietary quality, as well as their impact on public health. However, they face significant challenges in product and inventory management, especially in quality and stock control, which affects customer satisfaction and profitability. This research proposed a service model based on Lean Service tools, such as 5S, Kanban, standardized work and supplier certification, to address these challenges. The implementation of the model showed an 85% reduction in non-conforming products and a 50% improvement in employee performance. These results indicate a significant improvement in operational efficiency and service quality. The academic and socio-economic impact of this research lies in improving operational management and promoting sustainable practices. Researchers are encouraged to explore new directions that integrate Lean tools to optimize convenience store operations.
