I was about to suggest much the same thing. Instead of offering a month trial by default, only offer it when enterprise customers ask about billing. Then you can use it as leverage, in the "Here! I'm giving you something!" sense, rather than it just being an assumed perk. You've thus generated goodwill and can follow up the trial with an offer for a bulk 12-24 month deal.
You can still offer free trials by default to lower tiered customers, eg. consumers, small businesses etc. But they aren't the ones that you need to worry about 10%+ discounts on. Becuase they're so low billing that the rarity of the pre-trial discount will render the overall cost negligible.
