Personally, I had this happen with my business MedRev. It is a patient experience analysis SaaS that works by sending out satisfaction surveys to patients from clinics, offices, and hospitals and returning back to them actionable information on how to improve their companies and processes. When we were getting started, I didn’t put much thought into the cost of systems operations outside of support because “How much could it possibly cost to send a few emails and texts?” It turns out it’s a lot if you’re going to be in compliance with all the US healthcare regulations, also known as HIPAA. To get all of our training, insurance, other legal issues, and security within the system, the costs turned out to be exceptionally high. The difference between sending out surveys while complying with HIPAA regulations versus just sending out business surveys turns out to be SIX TIMES more expensive! If we hadn’t already been so far into the system when I realized how low the margins were actually going to be, I may not have pursued it in the first place.
