I've found a lot more software startups and SaaS companies using this method lately.
When I actually am interested enough to talk to their salespeople (and they're straightforward enough with me) they've told me it helps them target whales more easily.
They can charge a lot more to a huge Enterprise and adjust lower for SMBs.
Of course the fun part of that is when the sales staff mistake a minnow for a whale.
Case in point, a large FTSE, NYSE, NASDAQ listed company with largely siloed internal departments, all with their own budgets. Your yearly budget might be $20,000 -- but they see the Inc. or Plc. with a turnover in the hundreds of millions and quote accordingly...
I'm the same! I like to plan things, so if something doesn't allow me to fit it into my plan easily I will discard it as not an option.
Unknown costs, talking to other people, negotiating; these things produce trace amounts of anxiety. Anxiety I'd rather not deal with. A simple Pricing page solves this.
I'd rather spend an hour googling your competitors than contact someone for a quote.
(1) 'Enterprise' oriented software, in which case it is too expensive for you anyway (those long and personal sales trajectories, negotiations and commissions have to be recouped somehow)
(2) Not actually a product, but a Trojan horse to sell you lots of consulting and bespoke development services.
