Every number on this page is an assumption we chose, then arithmetic. None of it was measured from a customer. Change the inputs and the result changes with them.

Industry Context

In a small shop the service advisor is often the only person who answers the phone, and the same person is writing estimates and explaining repairs at the counter. Calls that come in during the morning rush or at pickup time ring out. This example assumes an average repair order of $650 and that 55% of answered calls turn into a job.

A service advisor at the counter can't pick up the phone
Morning drop-off and evening pickup are the busiest times at the counter
A caller who gets no answer can call the next shop
A driver who has broken down wants to hear back quickly

The Problem

The service advisor is stretched thin — juggling walk-in customers, writing estimates, coordinating with mechanics, and answering the phone. During the morning rush (7–10 AM) and end-of-day pickups (4–6 PM), calls stack up and go unanswered. A customer calling about brakes, a check engine light, or an oil change can call the next shop instead.
