Using PHP Laravel for the backend and Angular for the frontend, a progressive web application was designed, which was developed in cooperation with local Volunteer Fire Brigade (LFB). It is also suitable for working on web browsers on computers and mobile devices. The application was designed due to various existing problems in society, which this application could solve. Using the PWA application, that is a hybrid of the native app and mobile web app, is enabled also in offline mode. The aim of this paper was to show that nowadays the digitization of business really means everything. Achieving ease of use with a variety of options is really the ideal solution to the problem. The existing problems of this company, which motivated the writing of this paper were: insight into which firefighter needs new equipment or is missing some of the equipment, equipment storage itself, sending mass emails related to interventions, etc.. With this application, it was achieved that all its users (managers, storekeepers, firefighters) can have an accurate picture of the situation in the society at any time.
