This one swings a bat at “more leads = more money.” Shawn Gervais and Marshall Hill lay out the Predictable Profit Playbook for detailers: run a $0-ad year by anchoring your price grid with a decoy package that makes your “Best Value” offer irresistible, stack painless 10-minute upsells (chips, blades, glass clarity), and re-ignite past customers with a boomerang cadence at 2/4/6/9 months. We turn office complexes into a mobile-detailing funnel with the “We Wash While You Work” pitch, then kill no-shows using deposits, waitlists, and tight scripts. Along the way: why predictability beats cheap, how to sell outcomes (not services), the real difference between gross and net, and when franchising or hiring actually makes sense. Edgy, tactical, and instantly usable. Say it on every call: “We’re not expensive—we’re predictable: predictable results, predictable maintenance, predictable resale value.”
