The app is made for on-the-street salesman so it is optimized for fast invoicing. To avoid the problem that the manager's needs for reporting and dashboards overshadow everything else we split that from the main app. i.e: we have no report capabilities in the transactional. app interface and have instead integrated metabase for the managers. So, we split OLTP/OLAP as ux measure.
