I haven't found that to be the case. I used to run some retail and consumer services as well. People that spent $2 expected unending support. None of my B2B SaaS subscribers have needed much hand-holding. I get maybe half a dozen support e-mails a day, which often take just a minute or two to type out a reply to with some guidance. Mostly it's new users who just need some help with getting started, after which there is no support burden at all.
If you have 833 customers paying $100/mo, any one of them is just 0.1% of your revenue; you're not beholden to them individually. If they expect unreasonable things of you, then you might not be a good fit for them and can part ways. Sometimes firing a customer is the right thing to do. https://www.groovehq.com/support/how-to-fire-a-bad-customer
Yev from Backblaze here -> Definitely! We charge $5/month and have a support team that's inundated with folks expecting $100/month worth of support. There is something weirdly psychological about it, for example, if you're having a problem with Google, you don't really expect to call them up and complain, same with Facebook. But as soon as you're paying $2/month or $5/month you start expecting a lot of care, whereas if you're an "enterprise" customer, you most likely know the level of care that $100 buys you, so you're more reasonable. It's fascinating!
