Our project history

Our company history

PTA GmbH has witnessed and helped shape the development of IT

In 1969 ...

... Programmier-Technische Arbeiten GmbH (PTA GmbH) was founded in Mannheim. The aim of the company was to develop programs for technical calculations, particularly for heat requirement calculations in the construction sector.


Over the following years, the focus of our development work shifted towards commercial applications, especially in financial accounting and in payroll accounting. We not only developed programs for IBM mainframe systems and operated these using punchcards, we also performed accounting processes as a service for industrial concerns.


The increasing dialogization of application systems required ever closer cooperation with customers in order to solve organizational and conceptual design tasks together. For this reason, we deliberately focused our business activities on executing customer projects. Given the customers different requirements, we were able to gradually expand our range of services, which gave us in-depth experience of the most important development environments coupled with a variety of specialized knowledge of various industries.


Today, PTA consulting work no longer merely covers conceptual design and programming for individual systems. The increasing use of standardized applications in enterprises means that the comprehensive technical know-how built up by PTA consultants can now also be used to select, launch and enhance the most important standard software products on the market.


In 2005, we positioned ourselves to further expand the PTA Group's range of services and sphere of activity. In mid-2005, DATIS Software GmbH was founded (DATIS IT-Services GmbH since January 1, 2011), which took over the business segments for shop (outsourcing, hosting, cloud computing) and developing standard software for the logistics sector from a service provider that had long been active in this field.


At the start of 2006, PTA's business activities were expanded in Switzerland in order to provide on-site support for the local offices of long-term international customers and to open up new markets.
