Key Takeaways
- In a field experiment in central Mexico, providing merchants with digital payment devices alone resulted in low adoption (<12 % after six months).
- Adding consumer success managers (CSMs) who trained merchants and demonstrated tangible benefits increased adoption by 66.6 % versus a control group; a second round of benefit‑demonstration boosted uptake an additional 25 %.
- A cost‑benefit analysis showed the profit gains from higher digital‑payment usage would recoup the CSM program’s expense within six months to a year.
- Positive spill‑over effects were observed: neighboring merchants of participating shops were slightly more likely to adopt the technology themselves.
- The study underscores that technology rollout must extend beyond device distribution; ongoing support and early‑win demonstrations are critical for inclusive digital‑payment adoption, especially among lower‑socioeconomic‑status businesses.
Background and Motivation
The transition from cash to digital payments remains challenging in many developing economies, where limited digital literacy, entrenched cash habits, and skepticism about customer demand hinder adoption. Prior research highlighted benefits such as improved retailer performance, stronger consumer financial health, and better government tax oversight, yet uptake lags. Recognizing this gap, a Cornell‑led team investigated whether structured post‑installation support could bridge the divide between technology availability and actual use, focusing on merchants in Guadalajara, Mexico.
Experimental Design and Participant Recruitment
Researchers enrolled 479 local merchants and randomly assigned them to three groups. The first group received two visits from consumer success managers (CSMs) who provided hands‑on training on device operation. The second group received the same training plus CSM‑facilitated early trials designed to showcase concrete benefits, such as faster checkout and reduced cash handling risks. The third group served as a control, receiving only the free digital payment device and basic instructional literature without any follow‑up support. This design enabled the team to isolate the effects of training versus training combined with benefit demonstration.
Findings from the Control Group
Only about 12 % of merchants in the control cohort had adopted digital payments six months after receiving the device. Interviews revealed two primary barriers: roughly 60 % abandoned the technology because they found it overly complex, while another 40 % cited lack of customer requests, leaving them uncertain about the value of switching. These results echoed earlier observations that merely distributing hardware fails to overcome behavioral and perceptual obstacles.
Impact of CSM‑Led Training
Merchants who received CSM‑led training alone showed a 66.6 % increase in digital‑payment adoption relative to the control group. The structured, repeatable guidance demystified the technology, reduced perceived complexity, and built confidence in day‑to‑day operation. This outcome highlights the importance of skilled, person‑to‑person support in alleviating the anxiety that often accompanies new‑tech adoption among small‑business owners.
Added Value of Benefit Demonstration
When CSMs supplemented training with concrete demonstrations of benefits—encouraging merchants to run trial transactions, observe faster settlements, and experience lower cash‑related risks—adoption rose an additional 25 % beyond the gains from training alone. Seeing immediate, tangible advantages helped merchants justify the learning effort and convinced them that customers would indeed use the digital option, addressing the “no demand” concern highlighted in the control group.
Cost‑Benefit Assessment
A formal cost‑benefit analysis indicated that the financial upside from increased sales, reduced cash‑handling expenses, and improved transaction security would offset the expense of deploying CSMs to nearly 500 merchants within six months to a year. Even after accounting for staff salaries, travel, and material costs, the program delivered a net positive return, suggesting that investing in post‑installation support is economically viable for scaling digital‑payment infrastructure.
Spill‑Over Effects on Neighboring Businesses
An intriguing secondary finding revealed that merchants located near participating shops were modestly more inclined to adopt digital payments than those adjacent to control‑group retailers. Observing peers successfully use the technology created a informal learning environment and reduced perceived risk, indicating that adoption can diffuse through local networks when early adopters receive adequate support.
Broader Implications for Inclusive Growth
Lead author Shreya Kankanhalli emphasized that the average business owner in the study came from a lower socioeconomic background, for whom the shop represented a vital source of family and community livelihood. Without targeted assistance, digital divides risk concentrating technological benefits among already advantaged firms, undermining inclusive economic development. The study demonstrates that pairing technology distribution with sustained customer‑success‑style support can promote equitable access to digital financial tools.
Conclusion and Recommendations
The research affirms that successful digital‑payment adoption hinges not only on making devices available but also on providing ongoing, hands‑on guidance and early‑win demonstrations. Policymakers, fintech providers, and development agencies should consider allocating resources to consumer‑success‑manager‑style programs, especially in underserved markets. Such investments can accelerate uptake, generate measurable profit gains for small merchants, and foster broader financial inclusion, ultimately contributing to more resilient and equitable local economies.
