One BonusA loyalty program for a car wash
Updated 31 August 2026
A wash is a fixed price bought often, on impulse, with a queue outside. That is a stamp card and nothing else — every sixth wash free, no explanation required, and a scan that takes less time than the payment.
Six, and be quick about it
Six washes is a couple of months for a regular, which is close enough to matter. Ten is too far when the wash across the road is the same price.
A card of six is roughly a sixteen percent give-back paid only to customers who came six times — which is a far better trade than a standing discount visible from the road.
The scan has to be faster than the wash
A car wash forecourt has no room for a slow loyalty step. The customer shows a code from the phone through the window, the attendant scans it, and the stamp is recorded — the whole thing fits inside taking payment.
Weather and the quiet week
Demand collapses in rain and spikes after it. Once visits are recorded you can see the pattern for your own site, and a coupon on a slow week is aimed at the days that actually need help rather than the ones already busy.
Common questions
How many washes should a car wash loyalty card have?
Around six. That is a couple of months for a regular customer, close enough to influence where they stop. Ten is too far away when the wash down the road costs the same.
Will a loyalty program slow down the forecourt?
No. The customer shows a code through the window and the attendant scans it — it fits inside the time taking payment already takes.
