>I know my title is not very clear. But here is what I am trying to write. A customer asked for some features. I want to say the following (in plain English) "These features are added to the software free of charge and will work as long as you buy/maintain annual support." Is there a better way of saying it in "Business" language?

"The cost of the feature is {insert an outrageous sum, about twice what you think}. It is provided for free as a part of maintenance plan, for those who subscribe to it".
