ZAJA One is door-to-door sales software and promotion management software for agencies and field teams. The platform combines territory management, lead management, campaign management, team coordination, appointments, follow-ups, tasks, files, and activity tracking in one system. D2D sales teams can assign geographic sales areas, capture leads at the doorstep, document lead statuses, plan follow-ups, and monitor territory progress. Promotion teams can manage campaigns, locations, promoters, tasks, and field activities without relying on spreadsheets, chats, and disconnected tools. Managers get a centralized overview of teams, projects, leads, activities, and performance, while field staff can access relevant information from desktop or mobile. ZAJA One is designed for growing door-to-door sales agencies, promotion agencies, and field sales organizations that want clearer processes, better coordination, and one central platform for daily operations.
