This is, of course, one of the many reasons why I don't run a large, VC-scale business. I don't have the patience or desire to play these sorts of games.
Companies that seek to convert every single potential sale and feel a non-sale is a net loss tend to be the companies that I as a potential customer do not want to be a customer of. They tend to have shite customer support anyways.
At the end of the day, the "contact us" pricing clearly is not something that ends companies, otherwise nobody would use it.
> ["Call for pricing"] also means that the price isn't fixed, and that a good negotiator might be able to get a lower price than someone else.
But you also say:
> [A potential customer who doesn't want to talk to sales] could be a customer you wouldn't want anyways. Customers looking solely for lowest price tend to be nightmare customers...
So the potential customer who does call for pricing -- possibly with the intent to negotiate that price down -- is also potentially that nightmare customer who is just looking for the lowest price and will be a drag on your time and resources.
To me, the potential customer who just wants to get started without needing to suffer through a call with a sales person... well, that customer sounds at least as likely to be someone who will be a nice, quiet customer who uses your product and doesn't call or write in with inane complaints and issues all the time.
I don't think this is a good signal. I do agree that a potential customer who calls is probably more likely to sign up, but it's still an extra barrier to customer acquisition, no matter how you slice it.
The places that are using 'call for quote' on things available on Walmart tend to be people that don't want people of Walmart listed as a customer. However, again, in my experience, I haven't seen one of these. It's been for things that are going to have sticker shock level pricing.
A good negotiator is worried about more than price. There is quality, time to get the product, support. An lot of other things on those lines that I can't think of at the moment too. A good negotiator knows what is important to them and how to make the best trade off for their situation. Sometimes a good negotiator will offer more than the asking price because they know those others are important and if the company goes out of business they get none of them (this is rare, but it is sometimes needed).
