Detailing sells a fixed package against a variable car. A full interior is three hours on a clean sedan and four and a half on an SUV that has carried a dog to the lake every weekend for two years. The price is on a board on the wall. The extra ninety minutes are not on anything. DetailDesk US records the booking, the actual bay time and the difference.

Booked minutes and real minutes

Each package carries the bay minutes it should take, and each appointment records the minutes it actually took.

The variance is the single most useful number in a detail shop, because a package that consistently overruns is a price that has not kept up with the cars it is sold to.

Add-ons that reach the invoice

Pet hair extraction, headlight restoration, engine bay cleaning and wheel coating are recorded against the appointment as their own lines.

This is where detail shops most often give away money, because the add-on is agreed verbally in the bay and never makes it to the counter.

Cost that follows the detailer

A master doing a coating and a junior doing an express wash carry different hourly costs, and the appointment derives its labor cost from whoever did the work.

Product is drawn against the car, so a coating kit and a half gallon of shampoo land on the jobs that consumed them.

Margin per detailer and per package

The detailer summary totals appointments, minutes, revenue and cost per person and labels the margin.

Read together with minutes variance it usually identifies a package rather than a person: recon interiors are underpriced for the condition of the cars actually arriving.

Review exceptions every week

Resolve duplicate IDs, missing links, overdue balances, negative amounts, and open operational items in CHECKS before using the dashboard for decisions.
