It depends on what kind of product you're selling. Certain budgets in enterprise are seemingly unlimited, generally when it comes to improving sales. If you're selling security products (outside of the compliance-driven market), you won't find much appetite for large margins. If you're selling CRM products (which are a dime a dozen), you won't find large margins.

You have to find out where a business is willing to invest no matter what the price. I know it exists, unfortunately each industry (and each subset of each industry) is going to have a different area where price is no concern.
