Comment You sell it as service, but it's much more.... (Score 1) 729
You raise an interesting point, and I think there is a bit of truth that this may incentivise bad behavior.
But done right, and your service is much more than bug fixing. It's market research as you interact with customers and find out there current problem and their future needs. It's customer maintenance since each time you interact with your customer you are selling them again on why your company is the smartest, friendliest, easiest to work with, thus keeping them from buying competing products. It's customer tutorials as you explain how to setup the normal installation, and how to use, and why and when to use advanced features the customer isn't even aware of.
All of this can be used to help your customer understand the value that your company's support provides.
(Caveat: I just pulled this response out of my butt. I think it's truthy good, but ymmv.)
