Resources for service business owners

Free profit-leak check

Enter your own figures for a plumbing cost comparison, HVAC booking and capacity check, or roofing follow-up and direct-contribution check. Calculations run in your browser without an account; they do not cover landscaping or auto repair.

Five field guides

Each guide explains a question, shows its assumptions and math, and gives you a worksheet to repeat with your own records.

• Where is profit leaking from your plumbing jobs?

  Does the gap come from the price collected, time on site, parts, or return visits?

• Are HVAC bookings turning into completed jobs your team can handle?

  Is the constraint lost bookings, long jobs, or available technician time?

• Are roofing estimates followed up—and do accepted jobs retain margin?

  Are estimates going quiet, or are accepted jobs costing more than the scope allowed?

• Is your recurring landscaping route contributing after drive time?

  Which stops use more service and drive time than their collected price supports, and how does the route change when the season changes?

• Are auto repair estimates approved promptly—and what do comebacks cost?

  Are approvals waiting on communication, and are completed jobs retaining direct contribution after rework?
