About us

oneAssist is an IT consulting company with headquarters in Munich and two locations in Berlin. Through our long-standing partnership with Microsoft and specialization in Microsoft SharePoint and Microsoft Visio, we are the leading provider for SharePoint-based process portals. In addition, we offer a unique range of services and products. We work worldwide and advise small, medium and large companies from various industries.

Solutions with passion

We see ourselves primarily as IT consultants and "implementers". This means that, in contrast to large resellers, the focus at oneAssist is not primarily on the sale of licenses, but on our comprehensive services. We bring proven experience in all areas of consulting, strategic planning as well as programming and support companies in the integration of Microsoft products. Our broad product and service portfolio allows us to react flexibly to individual requirements and to develop software that is optimally tailored to your needs. In addition, we always keep our eyes open for our customers on the dynamic IT market and regularly integrate new solutions into our offering.

The Team

Our team, consisting of long-standing experts and specialists in their field, is united by one thing: the synergy of customer-oriented technologies and the partnership with Microsoft. Even though each customer brings individual wishes and diverse requirements to their project, we have the right tools and the expertise to solve the problem in such a way that the added value and workload reduction are quickly reflected in the customer's everyday business environment.
