A mobile app for truck delivery in grocery wholesaling, tailor-made for a very well-known supermarket and cash & carry chain leading in Germany and Austria. The mobile app has digitalized the entire workflow (saving lots of paper-work) for loading, delivery, unloading and returns of goods and subsequent reporting. The app runs on robust industrial Android smartphones, is connected to a mobile printer so that receipts can be printed on site, scans article codes including weight articles and can be operated in offline mode. Today the drivers are wondering how they used to live without the app!
