Binder clips can be used in lots of different ways.
They can seal a bag of chips or veggies. They can hold papers together or wires in a bundle. They can even serve a purpose in keeping your hat on your head.
Maybe what you offer is used only for one purpose. Fine if it is, but many times what we think is only used one way turns out to be a multi-purpose item. (A screwdriver does not just help you turn screws. It can open cans of paint, prop doors, etc.)
Services can be this way too. And building flexibility into your offer can serve your customers in more ways than you may imagine.
“Sorry, we can’t do that, we have to do it this way,” is an acceptable thing to say if you are installing a gas line. Processes and procedures need to be followed.
But if you’re doing anything where you’re creating something for someone else, building flexibility into your offer is crucial.
