What makes us special

Tradition & experience meet curiosity & perspective

We combine tradition and experience with curiosity and perspective. We were founded in 1975. For more than 40 years, our focus has always been the same. We develop visual scheduling software.

Visual scheduling (mainly via Gantt chart software) is our core competence. Our DNA is to develop this as software products which we sell globally. Our "traditional" products are tools for software developers. They help them build powerful and flexible Gantt charts.

Yet, we not only have a tradition, but we also have a perspective. We used our experience and built visual scheduling products for end customers. Based on state-of-the-art technology and "living" in the cloud. So today, we are all about achieving operational agility with visual scheduling. Other than just "Gantt charts", it puts into the foreground what people actually achieve with our software. This is the idea of our 2nd generation management and owners.

What our customers say

Tangible benefits achieved with visual scheduling

More satisfied employees through greater transparency

The German company planned its production "analog" for a long time. The resulting problems were to be solved by using an ERP without a planning board, but this did not lead to a satisfactory result. Only the VPS brought more efficient planning, smoother processes, and more satisfied employees. At Winter + Freis, they are delighted that "we have a very good tool with which to work".

On-time delivery improved

For a long time, the Danish company used Excel for its planning. In addition, the employees verbally kept each other informed about orders pending and those waiting to be processed. The VPS improved one criterion quickly: "Our KPI for delivering on time to customers has increased dramatically". But this is not the only added value gained by the VPS.

More efficient planning and better use of capacities

The Italian company used to plan masses of projects with Microsoft's ERP system Dynamics NAV but at some point, this was not sufficient anymore. Only the use of the VJS brought transparent data structure, better-informed employees, and more efficient planning.

Book your 15 minutes explorative session

We know that finding the right visual scheduling software sometimes is hard. We also know that sometimes it is hard for clients to figure out which of our visual scheduling software product lines is best for them.

If you are unsure how to proceed, or if you like to learn a bit more about our offerings, book a 15 minutes explorative session with us.

We will keep this meeting to 15 minutes. We will do no demo, and we will not pitch software. In essence, we will ask a bunch of question to understand your visual scheduling challenge.

Based on this, we either honestly tell you that our products are not a good fit for you. Or - we jointly come to the conclusion that we might be an option for you. In that case, we use these 15 minutes to agree upon the next steps.
