The PTA GmbH has experienced and helped shape the development of IT.
In 1969 the Programmier-Technische Arbeiten GmbH (PTA GmbH) was founded in Mannheim. A goal of the enterprise was the development of programs for technical computations, in particular for heat requirement calculations in the building industry.
In the following years, the focus of the development work shifted to commercial applications, especially in financial accounting and payroll accounting. Here, not only programs for IBM mainframe computer systems were developed and operated using punched cards, but also the accounting work was performed as a service for industrial companies.
The increasing dialogization of the application systems required an ever closer cooperation with the customer in order to jointly solve organizational and conceptual tasks. Therefore, the execution of customer projects was consistently placed at the center of business activities.
