Step one: record the starting condition
Before any cleaning begins, walk around the vehicle with the owner or take dated photos. Note scratches, stains, worn upholstery, cracked trim and personal items left inside. Check the fuel level, warning lights and any area the customer wants avoided. For example, a sedan arrives with a coffee stain on the rear seat and light swirl marks on the hood; both are logged so the stain can be treated and the paint expectations stay realistic. This record protects the customer and the detailer, and it sets the baseline for the final comparison.

Step two: divide tasks by zone and package
Organize the checklist into zones: exterior wash, wheels and tires, glass, interior vacuum, surfaces, seats and carpets, and final finish. Next to each zone, list the specific tasks included in each package, such as door jambs, cup holders or vents. Keep optional extras separate, including pet hair removal, odor treatment or headlight restoration, with their own time estimates. In the sedan example, the standard package covers every zone lightly, while the stain treatment is a clearly labeled add-on. Customers then understand exactly what is included before approving the work or paying extra.

Step three: inspect, report and schedule follow-up
Finish with a second pass under good light, checking streaks on glass, missed crumbs, wet edges and product residue. Tick each item and add notes where a stain or mark could not be fully removed. Share final photos and a short summary with the customer, including suggestions such as when to refresh the interior or protect the paint. In the sedan example, the report notes that the stain faded but remains slightly visible, and proposes a repeat treatment at the next visit. This honest closing step builds repeat bookings more reliably than exaggerated promises.
