This document discusses a contractor's marketing strategy and finances. It describes how the contractor, Carl, was only netting 5% profit despite a 40% gross margin due to low prices. The author suggests Carl raise prices by 10% to increase net profit per job from $250 to $750. This would lower Carl's break-even point for new marketing investments. The author also recommends Carl improve lead generation and conversion rates through inbound marketing to further boost profits. In several examples, the author shows how small adjustments to pricing and marketing could significantly increase Carl's annual profits and returns on investment.
