How car wash customers decide
The decision is made in the car, in traffic, in a few seconds: is there a queue and how long. Drivers who cannot find out simply keep driving. The business side has the mirror problem — peaks on Friday and Saturday, empty bays midweek, and no mechanism to move demand between them. And the most valuable product, a subscription for weekly washes, is almost never sold because there is nowhere to sell it.
What we build for a car wash
First, live queue or wait status per location, which is the single most useful thing a car wash can publish. Second, slot booking by bay and service, so peak hours can be reserved and midweek gaps can be discounted. Third, prepaid subscriptions and packages, turning an impulse purchase into recurring revenue. Fourth, loyalty tied to a phone number, so the regular is recognised without a paper card and can be reached with a midweek offer.
