Worth noting: costs for people blow costs for software/services out of the water. I was notoriously spendthrift with regards to SaaS services ("gotta catch them all!") and spent ~$3 on people last year for every $1 on services. (And if I had had any FTEs that would have been substantially higher.) Over ~10 years running SaaS apps I generally managed to pretty consistently find ways to spend 40% of revenue. Also worth noting: as you get further from "things which are made by devs-running-businesses-as-hobbies-for-devs-running-businesses-as-hobbies" towards "business inputs sold by businesses to businesses" costs skyrocket. You're going to spend plural thousands of dollars on bookkeeping and tax compliance every year. You will eventually need a contract reviewed; that will probably cost you a few hundred bucks. You're going to get a business insurance policy; you'll find the bidding starts at a grand. etc, etc
