I suppose it's all in the wording. Have the cheaper options but don't call them enterprise, and then have the really expensive enterprise option for managers for who the pain of being called anything but is more than a slight blip in the budget.

Giving them ways to pad their budget was also an eye opener for me. The idea that they might not even be conforming to our rational actor model of balancing cost and value opens up new pricing considerations. I wonder if a monthly 'flex' option where they can temporarily boost their budget to some ridiculous figure would work. The engineer in me does cringe at the thought of it though
