As someone who sits on the other side of that equation, $9/month basically translates to "1 support request per month". I've been meaning to do a blog post on such, but an average single support request costs us around $8. So if you've got a business where the average number of support requests per user are dramatically less than 1.0 per user per month, then it can work out, but I suspect there's a proportional suppo…
If I built a product that allowed you to answer support requests 10% faster, then logically you'd be happy paying an additional $750/month per support person for the software?
They didn't exactly show me the company budget, but I'm as capable of counting engineers as the next guy. Suffice it to say we paid way more than $75k a month for the productivity gains of that custom app. (It was my first encounter with Enterprise Software (TM) and I think I went into programming in part so that no one should ever again have to suffer like us CSRs suffered...)
