David Maister points out a satisfaction guarantee I love:
"If you’re interested in seeing whether we are right for you and your team, try us on a matter. What separates us from our competitors is that you have our value promise on every invoice. If you don’t think we’re worth the amount you agreed to pay, you make whatever adjustment you think is necessary. If your other firms don’t walk that walk, it’s time to try Valorem.”
Can this be taken further? "Pay as much as you think we’re worth."
If you like the work you’ll have to pay enough to retain the firm, otherwise other clients will buy their time. In effect, clients could bid for the agency’s time.
…if the Agency is good enough.
Who’s feeling brave?
