For Zagrebački Holding d.o.o., we developed the eJednostavna web platform, enabling faster, simpler, and more transparent execution of simplified procurement procedures online. The application provides businesses with easy access to all published procurement procedures, allowing them to apply, track progress, and communicate directly with the contracting authority. Designed to increase efficiency and trust in Zagrebački Holding’s procurement processes, the platform supports registration, viewing active tenders, electronic bid submission, and automated notifications about documentation updates. eJednostavna centralizes all relevant information in one place, significantly reducing the need for physical document submissions.
