Together with SUNZINET, we succeeded in bringing structure to our project

"To replace the existing intranet with a new, modern and above all up-to-date solution. For this, SUNZINET identified our needs, specified them and presented possible solution providers based on our requirements. Competent, cooperative, transparent and not to forget - very friendly. During the cooperation, it proved to be particularly valuable that SUNZINET is very broadly positioned due to its experience from many successful customer projects. Thanks to the cooperation with SUNZINET, we were finally able to select the right solution for us and gain clarity about how to proceed with the project."

Many thanks for the helpful guidance!

"Within 3 months we created a new intranet in the standard of SharePoint Online - with the exception of two specifically developed web parts. I am very excited about everything that is possible in the standard and what new possibilities the intranet offers with the embedding in the Microsoft 365 world! On this first stage of the exciting learning journey, we were able to implement many things ourselves - in doing so, SUNZINET stood by us with open questions in the realisation and supported us in particular with the web parts "menu" and "sales figures" developed by them."
