It's not just unethical, it's STUPID.


Label everything AND have a wiring diagram using a blueprint you got from the builder.

Charge accordingly. Accordingly meaning that you will make money regardless if you get the installation or not.

No better way to harm your business than doing half ass work. I know it's hard, but use a little bit of common sense.
