Dienstplanauswertung has many airlines, such as Lufthansa, as customers. They specialize in the evaluation of the work schedules that the tax return is based on.
On their website, they have a support form to be filled in by their customers. When the information is submitted, a new ticket is automatically created in HelpDesk without the customers entering the software and the support staff needing to generate tickets out of customer enquiries.
