It's my first time operating a software as a service business, so I'm not exactly sure how most customer interactions are supposed to go... Personally, I've always been an easy-going consumer of SaaS products; pay the bill, offer useful feedback, don't make unreasonable demands, etc...
I've tried to be really accommodating and reasonable with our prospects and clients, hoping that treating people with kindness would be good for business, but some of them seem to have an endless capacity to try and take advantage of us.
For example, on several occasions, we've listened to client's feedback and built new products which they suggested would be useful to the operation of their businesses, but once the software products are built, they've responded by claiming the new product is "their" idea, or trying to negotiate ownership of the software or our business, and even threatening to sue us if they don't get their way (no lawsuits yet)...
I'm wondering do you have these kind of customer interactions? I'm sure every business has difficult customers, but this has been a pretty radical cultural shift from the professionals I was working with at the investment bank...
