One of the inherent dichotomies for software vendors exploring new pricing models is: Who do you talk to? The common response is “Discuss this with your existing customers – they know best” There’s only one problem with that. Your existing customers have already most likely validated your current licensing processes – via the act of purchasing your software. To put it another way, when they looked at your pricing and licensing models they most likely found them to be agreeable enough (or at least not a big enough impediment) to moving forward.
The risk then as you explore new software licensing and pricing models is that you poll your existing customers only. While they’re an important constituent they should not be the only constituent. You need to look at the potential customers who did not buy your solution. Find out why they decided to go in another direction.
