Picked a usage based billing model over flat rate tiers for our API and got exactly 3 complaints in 2 weeks
Our top customer in Austin told me flat rate was simpler but usage based felt fairer, and when the invoice came in $40 lower than they expected, nobody emailed me about it, so has anyone else switched models and lived to tell the tale?
3 complaints in 2 weeks and one of them was basically a compliment about the $40 surprise, that's a win. I switched my side project to usage billing last year and my own mom emailed to ask why her invoice looked like a phone bill, so you're already ahead of me. Austin guy will come around once he sees a slow month hit his card for like $12.
