Testimonials describe what has been, and are a promise of what is to come.
The bottom line is a by-product of taking care of your main product - your customers.
Your profits reflect the success of your customers.
If your customers have to ask you for it, you haven't been thinking far enough ahead.
Even a tiny step is one step closer to where you are going.
When customers' expectations change faster than your willingness or ability to serve them, you can be sure they'll be someone else's customers soon.
