One problem with that approach in the enterprise is that most of that $100k+ software is stuff that takes a long time to customize and integrate; there's just no low-cost way to try something out. More peripheral services like instant messaging or collaboration tools are easier to do that with. Something like a CRM system is probably harder due to the volume of data you'd need to port and the large change in how people do their work, re-training required, etc. Something even more core like supply-chain management or an accounting system is even harder to try-before-you-buy, and the penalty for trying something that doesn't work is way, way higher. In order to get to the point where you know if it's going to fail or not, you have to take some big risks and sink in a huge amount of time and money.
