They did the same thing for everyone though (until they figured out how to scale that thing). It's not wrong to do whatever you got to do to get your first couple customers but you should also be thoughtful on how it's going to impact your company. For example, our second customer wanted us to do a deep integration into their erp system to sign on for $2k/mo, instead we did an audit of their current process and saw they were doing manual imports and exports. We gave them import/export capabilities which still greatly reduced their daily manual work and has been a longstanding, heavily used feature. They're still with us and both their revenue and the account has grown over 4x.
