Targeted WhatsApp surveys helped Yoco unlock price sensitivity insights across three products from 200+ segmented SME merchants
How Yoco used targeted WhatsApp surveys to unlock price sensitivity insights across three products — reaching 200+ SME merchants with Van Westendorp precision in a fraction of the time and cost of traditional research.
Yoco is one of South Africa's leading fintech companies, providing card payment solutions to small and medium enterprises across the country. As Yoco prepared to refine its product pricing strategy for three key devices — the Yoco Khumo Print, Yoco Khumo, and Yoco Neo Touch — they needed robust, quantitative insight into how their target market perceived price and value.
Traditional pricing research methods — phone interviews, email panels, in-person intercepts — are slow, expensive, and struggle to reach the fragmented SME audience Yoco serves. By partnering with Yazi, Yoco ran a Van Westendorp Price Sensitivity Meter survey via WhatsApp, reaching over 200 merchants who matched detailed segmentation criteria. The result was structured, high-confidence pricing data delivered in a format ready for strategic decision-making.
Pricing decisions for hardware products in a competitive fintech market demand precise, segmented data — not guesswork. Yoco needed to understand price thresholds from the merchants who actually use their devices, filtered by specific business characteristics.
Yoco's merchants span multiple industries, locations, and revenue tiers. Reaching a representative, segmented sample through traditional channels is prohibitively slow and expensive.
Van Westendorp requires respondents to consider four price points per product. Email surveys and phone panels suffer from drop-off on complex pricing instruments — especially with SME owners juggling their businesses.
Yoco needed respondents filtered by card acceptance, geographic location, formality of business, and revenue band — requiring sophisticated screening before the pricing questions even begin.
Product pricing decisions operate on commercial timelines. Yoco needed high-confidence data fast enough to inform active pricing strategy — not a six-week research cycle.
Yazi designed and deployed a Van Westendorp Price Sensitivity Meter survey via WhatsApp, targeting a minimum of 200 respondents who matched Yoco's precise SME segmentation criteria. The platform handled screening, survey logic, incentive management, and data delivery — all within the WhatsApp interface merchants already use daily.
The methodology combined rigorous survey design with WhatsApp's native reach and engagement advantage. A built-in checkpoint at 50 respondents allowed the team to review early data and adapt the approach before scaling to full sample.
SME merchants received the survey directly on WhatsApp — the same channel they use for customer orders and supplier communication. The conversational format made even the four-point Van Westendorp instrument feel natural, reducing drop-off and improving data quality.
The survey reached over 200 respondents who matched Yoco's precise segmentation criteria — SME merchants filtered by card acceptance, location, formality, and revenue. The structured data set included Van Westendorp price points for all three products, enabling direct comparative analysis across the Yoco device portfolio.
At the 50-respondent mark, Yazi and Yoco reviewed early results together. This checkpoint allowed the team to assess sample composition, confirm segmentation distribution, and adapt the survey approach before scaling to the full 200+ respondent target — a level of methodological agility that traditional pricing panels rarely offer.
Yoco accessed the study data through the Yazi platform — including structured table views of every response, segmented cross-tabulations, and the comparative product analysis that underpinned their pricing decisions.
| Traditional Pricing Research | Yazi on WhatsApp | |
|---|---|---|
| Respondent reach | Limited by panel availability and cost | 200+ qualified SME merchants |
| Screening precision | Basic demographics only | 4 custom filters: card, location, formality, revenue |
| Survey channel | Email, phone, or intercept | WhatsApp — where merchants already are |
| Engagement | High drop-off on complex instruments | Conversational format reduces abandonment |
| Mid-study review | Rarely feasible | Built-in checkpoint at 50 respondents |
| Delivery format | Static PDF report | Structured data + comparative analysis per product |
| Incentive management | Manual tracking and fulfilment | Automated within the platform |
High-confidence Van Westendorp data across three products, segmented by the merchant characteristics that matter most. Yoco gained a clear picture of price ceilings, floors, and optimal price points — enabling informed pricing decisions backed by real market data rather than internal estimates.
The project established WhatsApp as a proven channel for reaching Yoco's SME merchant base with structured research instruments. The speed and cost efficiency created a repeatable model for future pricing studies, feature validation, and market perception tracking.

Pricing research is only as good as the audience it reaches. For fintech products sold to SMEs — a dispersed, time-poor, hard-to-reach segment — traditional research methods often deliver either insufficient sample sizes or imprecise data. Van Westendorp demands respondent attention and honesty; WhatsApp delivers both by meeting merchants in a channel they trust and use daily.
This project demonstrated that rigorous pricing methodology and accessible distribution are not at odds. A Van Westendorp instrument can run conversationally on WhatsApp, reach 200+ segmented respondents, include a mid-study checkpoint for methodological quality control, and deliver structured, comparative data ready for strategic decisions — all without a single phone call, email panel, or in-person intercept.
