Once again, we impressed the expert jury in the competition held by the Center for Enterprise Research of Potsdam University and distinguished ourselves among countless providers.

This is a major step on our road to becoming the leading cloud ERP provider in Europe.

In 2019, weclapp got a new logo and thus a facelift! In addition, the corporate design was optimized and the application itself significantly improved.

This confirms that weclapp meets the high level of security and protection of sensitive data and information with regard to integrity, confidentiality, and availability. In addition, there was a change in the company’s legal form from GmbH (company with limited liability) to an SE, with the aim of expanding our international orientation.
2018 | ERP System of the Year 3 times in a row + 10 years weclapp
In 2018, weclapp received the “ERP System of the Year” award for third time in a row. The hard work and the experience gained over the last 10 years has paid off — weclapp is on the right track! In addition to the great successes, weclapp launches the web-enabled POS software weclappPOS in 2018!

The 💚 of weclapp

CEO Ertan Özdil

Ertan Özdil is CEO, founder & shareholder of weclapp. Ertan started programming computer games and demos at the age of 9. He continued to pursue this enthusiasm and passion for software and programming and thus began his career in the early 1990s with the development of a merchandise management system for an IT wholesaler. In 2001, he developed an open-source solution for customer relationship management, one of the first open-source CRM systems available at that time.

The know-how gained from these two key projects, as well as numerous process consultations in companies, led to the early and pioneering idea of weclapp in 2008: a cloud-based ERP software for all business sectors. Ertan was thus one of the first to recognize the potential of such an application and launched a cloud solution for corporate management. Even today, he is actively involved in the optimization of the ERP software and regularly develops new features for weclapp.
