The Injection Service application is a pioneering application for the data of the country's workshops. Replaces the classic electronic maintenance book with an electronic one. Every work performed is recorded either by us or by the customer. It should be noted that the first entry must be made by our workshop. Notices of planned future work are sent as well as notices of possible offers for some periods. Supports more than one vehicle per user. It is a tool for organizing their vehicle maintenance file.
