Even better, show me some preconfigured packages that you're willing to sell at a public price. If they look reasonable but I need more, I'll happily talk to a salescritter, now that I understand that I actually have a more complicated problem.
From an emotional level: Your concerns have to do with defending your purchase to others and your fear of looking like the fool who "overpaid" for the same product someone else got for less...
This fear should be satisfied with other messaging and tools than pricing transparency. Like, service promises, real testimonials, added value bonuses, and other tools to "feel like the cool kid" who go the best of them.
I have no idea what that means.
Assuming it is true, would you agree that your "perceived responsibility" in this case has more to do with your emotional needs than it does to your business needs.
your belief is that there are finite resources within the context of wealth, and the transfer of money is a zero sum game, where someone wins and someones else loses.
Your responsibility is to get the most value out of your resources, but you agree that your responsibility is to spend that money, and that money's function is to move around and create wealth.
Your "responsibility" to route "society's" resources to efficient producers, has nothing to do with actually accomplishing that, but rather how you value things and how you feel.
Besides, my point is... you are not getting "ripped off" if you perceive the value to be greater than what you pay. That money will move around, creating wealth along the way, and withholding that money for what you consider a more efficient usage of it is certainly your right, but far from making any difference in how efficiently society produces...
I do agree that you have a responsibility to yourself to utilize your resources as efficiently as possible, but I hardly think that responsibility extends to everyone participating in the market.
The simple reality is that people make purchase decisions based on emotions and justify their purchase after the decision is made with logic and reasoning.
Whatever logic helps you sleep at night is fine with me, but the reality is we are beasts of emotion and make our decisions based on those emotions.
Why not offer default packages with a fixed price for small and medium sized businesses and encourage those that have specific needs/concerns to leave their details to discuss the possibilities and get a quote?
With that being said, many software and web applications that use the "contact us for a price method" that aren't just vultures looking for your info usually need more information in order to price you properly. For example, the size of the company, your budget, your specific needs etc. may be needed to ensure that the company gets a fair specific price that caters to their needs.
