Consulting rates and enterprise software pricing are two different beasts, especially when hosting infrastructure is involved...
On top of this, enterprise buyers are not always going to be sophisticated enough to determine whether their business requirement means they need module a or b or feature x vs. y from a random enterprise suite.
In our field though, there are a lot of competing products, and a lot of them are either free or very cheap. And at a high level, they have similar "features" and "benefits". But once you get down to the nitty-gritty, there are tons of differences. That's why we spend a lot of time and effort educating our clients on those differences. We have to demonstrate the value first before providing the price in order to avoid sticker-shock.
As a counterpoint to this, my cofounder and I have been very successful with our own security consulting firm with the opposite philosophy. We have not found transparent pricing to be an obstacle in landing lucrative clients. I also haven't seen any race to the bottom of "commiditization" in our industry. One of our closest competitors also publicly lists weekly rates.
I don't know that they care one way or another. It's not as though we champion transparent pricing in our sales pitch - it's simply one more available piece of information on our website. Potential clients still need to contact us, they just know what to expect. We haven't found that we have pressure to reduce our prices or compete on price as a result. Granted, we cater to more YC companies than we do Fortune 500s, but we still serve both, and the firm does very well.
The vast majority of our work comes in through referrals, which probably changes things a bit. I think there is merit in either approach, enough that it's not fair to say one definitively causes this or that as a result.
