Pricing is something that you're never going to get perfect right off the bat. Start high, then figure things out with your customers. Remember that it's easier to lower prices than it is to raise them.
I will say that it's quite common to have a super-high price tier that hardly anyone buys, that is there to make the other tiers look cheaper by comparison. Not saying that it's a tactic that works 100% of the time, but anecdotally speaking, I see it around on SaaS websites.
e.g.
Basic - $30
Premium - $50 most popular!
Corporate - $200 (comes with super-duper feature that 99% of people don't need)
