How a Two-Location Car Wash Grew Sales 17% While Cutting Marketing Costs by 90%
Automated Rewards • Customer Signup with QR Code and SMS • Easy to Use Solution
Overview
Acme Car Wash is a family-owned business operating two locations in Salinas, California. With more than 50 years in operation, the company had built a loyal customer base but relied heavily on traditional coupon promotions and seasonal discounts to drive repeat visits.
While traffic was steady, marketing efforts were inconsistent and costly. The owners wanted a way to increase customer retention and generate more predictable repeat business — without adding complexity to daily operations or requiring POS integration.
After implementing Riiwards’ automated rewards system with SMS-based signup, Acme Car Wash saw measurable improvements in both customer engagement and financial performance.
The Challenge
1. High Marketing Costs
The business spent approximately $2,500 per month on coupon mailers and promotions, with limited visibility into long-term impact.
2. No Direct Customer List Ownership
Without a structured customer database, follow-ups were sporadic and dependent on broad promotions rather than targeted engagement.
3. Operational Simplicity Required
Previous loyalty solutions were evaluated but rejected due to complexity, required staff involvement, or POS integrations that would disrupt workflow. The owners needed a system that would run quietly in the background — without slowing down their tunnel operations or requiring additional training.

“I was using multiple products that weren’t boosting my sales. Now, with Riiwards alone, my sales have increased by 17% at less than half the cost. Customer service is outstanding!“
— Gigi E., Manager, Acme Car Wash
The Solution
Riiwards implemented a simple, automated rewards program tailored to the fast-paced nature of a tunnel wash environment.
Customers joined via a self-service SMS signup process by scanning a QR code on-site or through the website. The process took less than a minute and required no app download. Once enrolled, customers automatically received:
- Birthday rewards
- Anniversary rewards
- Occasional monthly offers
The system required no POS integration and no ongoing staff involvement. It operated independently while building a growing, verified customer list. Acme Car Wash enrolled 2,711 customers and achieved a 17% increase in sales while reducing marketing costs by approximately 90%.
The Full Story

About Acme Car Wash
Acme Car Wash is a family-owned business in Salinas, California, serving the community for more than 50 years. With two locations—including a Chevron gas station site—Acme combines high-volume tunnel washes with full-service cleaning, detailing, hand washes, and oil change services.
Gigi E. has been in the car wash business for 34 years, with 20 years managing Acme Car Wash’s day-to-day operations. His philosophy: “A returning customer is more valuable than finding new ones… keeping him is harder than getting him.”

The Challenge
Despite steady daily traffic, most customer relationships ended after a single visit. Acme relied for years on coupons and local advertising, spending an estimated $2,500 per month on Safeway/Albertsons receipt-back programs and Valpak mailers, yet results were short-lived and difficult to measure.
More advanced loyalty systems were evaluated, but anything that slowed throughput, required staff involvement, or added checkout friction conflicted with Acme’s tunnel wash operation. As Gigi notes, he saw customers “walking away” from complicated sign-up processes at other locations. The business needed a way to drive repeat visits without disrupting speed or increasing operational overhead..
Services & Customers
- Strong daily traffic, but limited customer data
- One-time visits dominated; repeat behavior was hard to influence
- Relied on coupons and discounts for years
- Estimated marketing spend of ~$2,500/month
- Short-term lift, no measurable long-term impact
- Evaluated several digital marketing solutions—none worked
- Rejected due to friction, staff involvement, and slower throughput
The Solution
Acme implemented Riiwards as a lightweight, automated engagement solution focused on long-term customer relationships. The setup centered on event-based rewards—signup, birthday, anniversary, and monthly offers—delivered automatically throughout the year.
Initially, customers joined via a simple email signup. In March 2025, Acme introduced SMS-based signup, dramatically reducing friction and ensuring verified contact data. The system required no POS integration, no redemption tracking, and no ongoing staff involvement.
The decision to adopt Riiwards was quick. As Gigi recalls: “Actually very quick, when the owner saw how it worked.” They implemented it and have “not missed one month” in more than 4 years.
The Setup
Automated rewards & communication:
• Signup reward
• Birthday reward
• Anniversary reward
• Monthly recurring reward
• Monthly newsletter with seasonal offers
Signup method:
• Email-based signup (4+ years)
• SMS signup introduced in March 2025
Operations
• No redemption tracking required
• No POS integration needed
• Simple staff involvement at redemption
Customer data captured:
• Email address
• Name
• Birth month & day
• Anniversary month & day
• Gender and age group
Result: Long-Term Engagement
Over more than a decade, Riiwards helped Acme convert anonymous wash traffic into a growing, permission-based customer audience. Engagement remained stable over time, with reward emails averaging a 22% open rate and the annual newsletter reaching up to 62%—well above typical benchmarks for local service businesses.
Unsubscribe rates stayed low at 0.39% per month, indicating that customers valued the communication. Riiwards also enabled Acme to collect meaningful customer insight and feedback, including 722 private reviews with an average rating of 4.5 stars.
The monthly newsletter proved to be a powerful engagement tool. Gigi uses it to promote seasonal offers—such as 20% off interior detailing and shampoo services during winter months when interiors get dirtier, or dollar-off wash specials during other seasons. The newsletter’s 62% open rate reflects genuine customer interest, and the engagement goes both ways: customers have come to expect these communications and will actually call or visit the store if they don’t receive their monthly or birthday rewards. This “expectation of value” is a strong indicator that the Riiwards program has become embedded in customers’ relationship with the business—not just a marketing channel, but a perceived benefit of being an Acme customer.
Taken together, the results show that a simple, low-maintenance engagement model—run consistently over time—can outperform more expensive, short-term marketing efforts and deliver durable customer relationships.

Business Impact
Beyond engagement metrics, Riiwards delivered measurable business impact for Acme Car Wash. By replacing discount-heavy marketing and multiple disconnected tools with a single automated system, Acme significantly increased repeat visits while reducing ongoing marketing costs.
Sales increased by approximately 17% compared to the period before using Riiwards, while monthly marketing spend was reduced by 90%. Instead of recurring coupon campaigns, Acme invested in predictable, automated customer engagement that continued to generate value year after year. The result was higher revenue per customer, lower acquisition costs, and a more efficient marketing operation.
Gigi estimates that Riiwards drives approximately $7,000 in monthly revenue—a 35× return on the $200 monthly investment. As he puts it: “Riiwards builds up the customer base. Once 2,400 people are hooked in, it’s hard for them to leave for competitors unless I really fail on service.”
Business Results
• Sales increase compared to prior Riiwards: 17%
• Monthly ROI of Riiwards Club: 3,400% (35× return)
• $ spent per month for marketing before using Riiwards: $2,500
• Marketing cost savings: 90%
• Estimated monthly revenue from Riiwards: $7,000
• Estimated annual revenue from Riiwards: $81,000
SMS Impact and Key Learnings
The introduction of SMS-based signup in 2025 marked a clear acceleration point. Signup conversion increased by roughly 2× compared to the previous email-only flow. SMS did not change where customers came from—it changed whether they actually joined.
In-store SMS signups captured customers who would otherwise be missed, while a single SMS flow unified online and offline acquisition. The initial spike reflected a catch-up effect, confirming SMS as a structural improvement, not short-term hype.
Gigi emphasized that reducing friction is critical: “For people to sign up themselves, it’s easier than you just gonna force somebody… They feel pressured when you have something like that.” The self-service QR-based SMS signup eliminates that friction while capturing verified contact data.
Key Take-aways
Acme Car Wash’s 11+ years of experience show that effective customer engagement doesn’t require frequent promotions or complex loyalty systems. Consistent, event-based rewards delivered strong engagement while keeping unsubscribe rates low—because communication stayed relevant and infrequent.
The data also confirmed that reducing signup friction is critical. Customers readily shared personal information when the value was clear, which led Acme to introduce SMS-based signup in March 2025. SMS further simplified opt-in, improved data quality, and aligned better with the fast-paced nature of a tunnel wash operation.
Overall, Acme’s results demonstrate why Riiwards works particularly well for car washes: it runs quietly in the background, requires no POS integration or staff involvement, and supports long-term customer relationships without disrupting daily operations.
Key Take-aways
- Increased revenue 17% while reducing marketing costs 90%
- Replaced $2,500/month coupon spend with $200/month automated engagement
- SMS-first signup doubled conversion without increasing traffic
- Low-friction systems outperform complex loyalty programs in high-volume businesses
