Your business.
Your challenge
We solve it.

For more than 25 years…

Plan Software has advised and supported its customers and partners reliably: We find software-based solutions for your problems. From the very beginning we had the vision to specialize in electronic product catalogs and everything that goes with them. This is how our very specific expertise came about: intelligent catalogues for industrial companies in the B2B sector. The technology is developing rapidly – and we were part of it.

Globally acting

From Saarland to the world. With initially mainly German customers, our software expertise also enabled us to achieve an international breakthrough. But above all, it is the diversity that appeals to us! Globally operating companies often have to take regional market conditions into account and we support this. With our network we are active for our customers worldwide.
