Dave, I don't actually put the price I pay for material on an invoice, just as the supplier does not list the price that they pay for that material.(They don't give it to you at cost) The markup is there in part to cover the time you spend getting that material. If a customer calls five contractors and asks how much per hour to wire six receptacles they will remember who was $5.00 an hour more expensive than the other guys. Markup is an integral part of your overall dollar intake. Why give it up?
