Off-topic, but unlike the example pricing plans, don’t make your SaaS’s “standard” plan $10/month. If you want a place to start, start with $50/month.
Or, as Patrick McKenzie used to tell us over and over, “charge more”.
(Yes, yes, I know some situations, customers, product, thinking, etc are different. But with broad brushstrokes, my advice is to not even entertain such a low price.)
