We’re adjusting pricing on March 1

We’re adjusting pricing on March 1st

Controllab will be adjusting the prices for 20-sim and 20-sim 4C beginning March 1. The average price raise in euros will be 5%. This reflects the cumulative inflation since we have last raised our prices in 2014.
If you want to lock in on our old pricing before the change is made? You can purchase new software or renew your annual maintenance contract before March 1 and we’ll honor our old prices. Just send us a PO before March 1st.

If you are interested in upgrading to a newer version of 20-sim, we'd be happy to honor our previous pricing till the mentioned date.
Do you have any questions or concerns? Just send us an email. We’ll get back to you quickly.
Thanks always, 
The Controllab Team
