A municipality is an administrative entity that refers to a city. Ecuadorian municipalities regularly perform manual inspection processes in stores to calculate municipal charges. However, they have identified that these manual processes are time-consuming and have high costs. Also, the human mistakes existence in obtaining information from stores and the difficulty to manage the inspection processes themselves are problematic. In this context, it raises the technological needed of having real-time information from processes carried out for the municipality. Thus, the goal of this study is to automate the inspection process in economic activities at Ibarra – Ecuador municipality through the mobile app development using Mobile-D methodology. The MVC software architecture (Model, View, Controller) and the ScriptCase, Android Studio, PostgreSQL and REST web services tools were applied. The mobile app quality of use was evaluated by using ISO/IEC 25022 standard, and USE questionnaire (Usability, satisfaction, ease of use). And moreover, it was considered a Wilcoxon statistical analysis to verify the improvement of the automated process compared to manual. From results, it was observed that process automatization improved the information obtained at Ibarra municipality, and 84,32% was achieved with respect to the quality of use by considering the mobile app users.
