1. Launch a SaaS app that people like, with self-service signup and monthly billing by credit card.
2. Continue to grow and become more successful.
3. New leadership comes in, and decides that the path to growth is hiring a bunch of sales people and selling to "enterprises" instead of self service people with credit cards.
4. The sales people start selling to enterprises and promising terms that not only can the billing system not support, but that engineering hasn't even been asked to look into yet.
5. Yell at engineering for not "supporting our sales team" and try to get them to fix it, without slipping other feature launches, and without hiring more engineers.
6. Look like an idiot to all of your enterprise customers because you're selling them a product that was never designed for their needs, and without appropriate engineering scale to change it.
