Geared towards courier companies' customers. Customers can place orders, monitor their status in real time, display source and target locations on a map and generate aggregated results presented in a bar graph. Customer admins can also manage their user base, validate signup requests, manage service types and orders. CDS uses a server component which can be hosted by the courier company or hosted by syscall.com. A valid customer account must be issued by the courier company. Requires iOS 4.3+
