01 / Overview

DSO Retail & Grosir is a sales and field operations application designed to support DMLT Group’s sales team in managing product sales and daily activities directly in the field. The application helps sales representatives manage customer visits, product information, orders, transactions, and sales activities in a more organized and efficient way. By bringing key sales workflows into a single mobile application, DSO helps field teams streamline daily operations, monitor their activities, and manage retail and wholesale transactions while improving operational visibility and coordination between field teams and management.
