I also think the trend will be to bill per solved ticket (many are starting to offer this), and thus based on the outcome. But I also have a hard time with pricing that isn’t clear, such as “~XXX Resolutions/month.” I don’t have a solution at all, but from a customer’s perspective, I’d be pretty cautious. If there’s one area where I’m not a fan of approximations, it’s definitely pricing. Maybe the future will prove me wrong, and people will be comfortable with it.
