The problem
Integrated the installer management system into Multichoice's payment process so installers are paid accurately and on time.
Direct ordering and order management: menus, orders, payments and fulfilment, with automated order intake and status updates that cut merchants' operational overhead.
South African legal information is scattered across portals with limited keyword search, while international e-discovery platforms are often priced beyond the local market.
