The Callback Tax
Cost: 8–15% of marginEvery callback costs you the tech’s labor, the truck roll, the overhead, and the revenue from the job that tech could have run instead. Industry data suggests the average HVAC callback costs $200–$500 when you include opportunity cost. At a 5% callback rate on 2,000+ service calls, that’s $20,000–$50,000 a year walking out the door.
Unbilled Time
Cost: 15–25% of tech timeTravel between jobs, time spent on estimates that don’t close, warranty work that never gets charged, admin hours that don’t appear on any invoice. In most field service businesses, a massive chunk of technician time is non-billable — and nobody is measuring it.
Scheduling Waste
Cost: 5–10% revenue capGaps between appointments. Technicians crisscrossing town instead of running tight routes. Emergency calls disrupting the board. Every scheduling gap is revenue capacity that disappears forever — you can’t invoice an empty slot.
Inconsistent Job Quality
Cost: Compounds All LeaksResults depend on which tech shows up. One tech follows the checklist. Another skips steps. The customer experience varies wildly, and the callbacks from inconsistent work cycle back into the first leak on this list.
How we fix it for field service businesses
Same 3-phase methodology, adapted for the speed and constraints of running trucks and managing technicians.
Map the real workflow
We trace how a job actually moves from dispatch to invoice — not how the manual says it should. We ride along, review tickets, and talk to your techs. The Profit Leak Map shows exactly where the breakdowns are.
Install daily correction loops
Pre-job checklists that catch common callback causes. Post-job verification steps. Scheduling rules that minimize dead time between appointments. Built using your existing dispatch tools and CRM — no new software.
Track and tighten monthly
Callback rate, first-time fix rate, billable utilization, revenue per truck per day. We set up the KPIs, review them monthly, and adjust the guardrails as your business grows.
Real Results.
Real Margin Recovered.
A multi-location restaurant group was seeing food cost percentages swing 5+ points between locations with identical menus. A 72-hour diagnostic revealed the gap was entirely in prep execution — no standardized portion controls, no waste tracking, and opening procedures that varied by manager. After installing prep checklists and weekly waste tracking, food cost variance dropped to under 1.5% within 90 days.
