The recommendation: no stamps for subscribers, stamps for everyone else
A monthly unlimited-wash subscription is already the retention mechanism — the customer has committed and paid in advance, so a stamp card adds nothing for that segment. Reserve stamps for the pay-per-wash customers who haven't subscribed, where a card genuinely gives them a reason to keep coming back to you instead of the wash down the street.
The two customer groups are solving different problems for the business. Subscribers are retained by the subscription itself; pay-per-wash customers are the ones who still need a nudge, and that's exactly where a loyalty card earns its keep.
Subscription retention vs. stamp-card retention, side by side
It helps to see why these two mechanics don't compete with each other — they cover different customers and different failure modes.
| Monthly subscription | Stamp card | |
|---|---|---|
| Who it retains | Already-committed subscribers | Pay-per-wash customers with no commitment |
| Payment model | Prepaid, recurring | Pay per visit |
| What it protects against | Subscriber churn at renewal | One-off customers drifting to a competitor |
| Best paired with | Points on add-ons (detailing, interior) | A visible reward like a free wash |
Where a card still helps subscribers: add-ons, not the wash itself
Subscribers don't need a reason to wash their car — the subscription already covers that. What they do respond to is a reason to buy the things the subscription doesn't include, like interior detailing or tire shine. A points card tied to riyals spent on add-ons rewards exactly that spend, without duplicating what the subscription is already doing for the wash itself.
This is a case where running two mechanics on two different cards, or one points card scoped to add-on purchases only, makes more sense than trying to force one card to cover both a prepaid subscription and pay-per-visit stamps.
- Subscriber washing under their plan → no stamp needed, the subscription already retains them
- Subscriber buying an add-on (detailing, interior) → points card tied to add-on spend
- Pay-per-wash customer, flat price → stamp card, free wash after a set count
- Mixed customer base → run the stamp card for pay-per-wash only; don't enroll subscribers into it
A concrete example: a wash with both customer types
Take a wash with 200 monthly subscribers and 300 pay-per-wash customers a month. Enrolling all 500 into one stamp card wastes stamps on the 200 who were always going to wash regardless of a reward, and dilutes the meaning of the card for the 300 who actually needed the nudge. Enrolling only the 300 pay-per-wash customers, at the Free plan's 100-customer ceiling, means this wash needs Growth (unlimited customers, 85 SAR a month) almost immediately.
If the subscribers also get a points card for add-on spend, that's a second card on the same account — Growth supports up to 10 cards per dashboard, so running a stamp card for pay-per-wash customers and a points card for subscriber add-ons fits comfortably within one plan.
Keeping subscribers engaged without a stamp card
Waya's automatic triggers still apply usefully to subscribers, even without a stamp mechanic. A welcome message on signup and a reward-redeemed message when they use an add-on reward both fire the same way regardless of whether the underlying card is stamps or points. The 14-day win-back trigger is less relevant to a subscriber who's paying monthly regardless of visits, so it's worth turning that particular trigger off for the subscriber-only card and keeping it on for the pay-per-wash stamp card.
A short renewal-adjacent message works better for subscribers than a generic win-back nudge: "Your wash plan renews Friday — bring the car in before then." That's the kind of message a subscription business actually needs, and it's a one-off or scheduled campaign rather than an automatic trigger. If pricing on the add-on side genuinely varies, pair it with a points card tied to spend rather than a flat stamp.
Setting up two customer segments on one dashboard
None of this requires two separate accounts — one dashboard, up to 10 cards on Growth, and audience targeting that can send to a lifecycle segment, a specific program, or a hand-picked list.
- Separate subscribers from pay-per-wash customers
Track which customers are on a subscription, even if that billing happens outside Waya.
- Build a stamp card for pay-per-wash only
Set a realistic threshold — 6-7 visits is a common default for flat pricing.
- Build a points card for subscriber add-ons
Tie points to riyals spent on detailing, interior cleaning, or other extras outside the subscription.
- Turn off win-back for the subscriber card
It doesn't map to a subscriber's usage pattern the way it does for pay-per-wash visitors.
- Schedule renewal reminders separately
Use a scheduled campaign to subscribers around their renewal date instead of the automatic win-back trigger.
The limits to keep in mind either way
Regardless of which mechanic runs on which card, Waya has no POS or till integration, so a subscriber's add-on purchase or a pay-per-wash visit is only recorded when staff scan the card on an ordinary phone — subscription billing itself happens outside Waya entirely. There's also no SMS channel, so renewal reminders and win-back messages both land as wallet lock-screen notifications, and the Android merchant app is still in closed testing, so Android staff use the web dashboard.
Frequently asked questions
Should subscribers be enrolled in a car wash's stamp card?
No. A monthly subscription already retains that customer, so a stamp card adds nothing and dilutes the card's meaning for pay-per-wash customers who actually need the nudge. Give subscribers a separate points card scoped to add-on spend instead, if you want to reward them at all.
What should a car wash reward its subscribers for, if not visits?
Add-on purchases the subscription doesn't cover, like interior detailing or tire shine. A points card tied to riyals spent on those extras rewards real incremental spend without duplicating the subscription's own retention effect.
Should the 14-day win-back trigger apply to subscribers?
Generally no — a subscriber pays monthly regardless of visit frequency, so a win-back nudge doesn't map to their usage the way it does for pay-per-wash customers. A renewal-date reminder, sent as a scheduled campaign, fits subscribers better.
Can a car wash run a stamp card and a points card at the same time?
Yes. Growth supports up to 10 cards on one dashboard, so a stamp card for pay-per-wash customers and a separate points card for subscriber add-ons can both run from the same account.
Does Waya track subscription billing itself?
No. Waya has no POS or till integration and doesn't process subscription payments — it tracks loyalty activity only, recorded when staff scan the customer's card on an ordinary phone. Subscription billing happens through whatever payment system the wash already uses.
