Car Washes: How to Check Washes Without Receipts

Cars washed but not rung up. How to match bay entries with issued receipts and spot other losses at the car wash.

19 October 2026 · 6 min read · Vigilessa Team

At a car wash, losses often take a specific form: cars come in, get washed, and leave without the service being recorded. With cash payments, these losses are hard to spot—especially when the owner isn’t on site.

How Unrecorded Car Washes Happen

Basic Check: Cars vs Receipts

Count the cars entering the bays or tunnel and compare with the number of receipts and the types of services sold. For example: if 120 cars enter in a day and you have 105 receipts, the 15-car difference is worth investigating—even if some have explanations (a repeat wash, a test run).

Other Losses Detected by the Camera

Damage Claims

‘You scratched my car’ is a common complaint. Footage of the car entering the bay, showing its condition before the wash, quickly resolves many of these disputes.
