> To give you an example, I was quoted 12,000$ per year for an enterprise b2b database solution to record questionnaire answers. Great software, meeting a need we have. But I’m building a basic postgresql database and a very basic web front end for free in its place. 80% of the functionality, 0% of the cost. Your ROI calculation is wrong. Your homegrown solution costs you [your hourly wage] x [hours spent working on it] + [infrastructure costs]. If you have an engineer who spends 3 or more weeks a year on this (incl. initial development cost amortized over # of years), then you lost money. Worst, you spent time building a commoditized solution which you could have spent improving your own product!
