Bad Idea #1: Site Licenses.
The opposite of segmentation, really. I have certain competitors that do this:
they charge small customers per-user but then there's a "unlimited" license at
a fixed price. This is nutty, because you're giving the biggest price break
precisely to the largest customers, the ones who would be willing to pay you
the most money. Do you really want IBM to buy your software for their 400,000
employees and pay you $2000? Hmm?
As soon as you have an "unlimited" price, you are instantly giving a gigantic
gift of consumer surplus to the least price-sensitive customers who should
have been the cash cows of your business.

Assuming you had everything planned down to the last detail when you started
work, EBS works great. To be honest, though, you may do some features that you
hadn’t planned. You get new ideas, your salespeople sell features you don’t
have, and somebody on the board of directors comes up with a cool new idea to
make your golf cart GPS application monitor EKGs while golfers are buzzing
around the golf course. All this leads to delays that could not have been
predicted when you did the original schedule.
