Good Morning,

Can anyone tell me the difference between Maintenance and Subscription for AutoCAD?

We have been on Subscription for many years now and have paid out Subscription fee every year for the newest release as well as other benefits. Now our re-seller is showing us a new pricing model which looks like we are now on Maintenance and how much we will save over the next 3 years if we switch to Subscription. Our sales guy tried to explain it over the phone, but I just didn't get it. I have asked for a written description, but have not received it yet.

Any thoughts?
David
