Stroyudacha store chain wanted to reduce the time it took for a customer to place an order in the store, as well as decrease the load on sales assistants. The solution is a QR-code scanner of goods in the mobile app that allows placing an order, while being in the store. Now there is no need to search for a sales assistant, while being in the warehouse or in the store - the customer can see the availability, characteristics, and price of the goods in the app.
