If there truly is no meaningful exchange of details before giving a price, pretty much yes. (although tbh even "who is the client" can be relevant - few people are going to put "in our experience companies in industry X are always a pain to work with and cause more support needs, and thus we'll bill higher" on the website, but if you have few high-value contracts that's a relevant concern. Not so much if you sell many small things.)
