In any engagement, your client each pay a price for success. Your price is paid with labor — theirs with dollars.
The first task for a marketer is to find out what success means to the client.
Often it involves finding more of their best customers. Or, they may need clarity about how and who they serve in order to better communicate their value offer.
Whatever the case, they are paying you for an outcome, not expertise, time, or effort.
The price of success for you is to determine and deliver the optimal outcome for your client and keep it front and center throughout the engagement.
How effectively you uncover and execute the outcome is what will determine whether the client sees you as an investment or an expense.
