Prospect: "I love what I'm seeing, I think this can work for us. I just have to take this back to my boss."
AE: "Great! I have a bit of a direct question, but I'm curious...if you were to take this back to your boss and they say no, what will happen?"
I personally have asked this question at the end of sales demos.
Creating a "future" environment of a deal in the present opens up a can of concerns.
It's easier to address concerns when you still have the prospect's attention.
2 reminders before you ask this question:
1. Soften the "blunt" question by saying you have a blunt question
2. Make sure the question is open ended
Try it on your next call.
