Small Retailers Need More Than Tech to Adopt Digital Payments

Why It Matters

The study shows that practical support, not just cheap hardware, is critical for scaling digital payments in emerging markets, directly impacting financial inclusion and merchant profitability.

Key Takeaways

• Installation support doubled digital payment adoption among Mexican retailers
• Full onboarding raised transaction volume from three to five payments per month
• Structured support cut effective adoption cost by up to 63%
• Nearby untreated merchants also increased adoption, showing spillover effects
• Digital-payment merchants earn ~57% more profit than cash-only peers

Pulse Analysis

The push to digitize payments in emerging markets often stalls at the implementation stage. In 2018, Mexico’s government distributed free point‑of‑sale devices to thousands of small retailers, yet only 12 % were still using them after six months. A Stanford‑led field experiment in Guadalajara revealed that the real obstacle was not the hardware price but the complexity of installation, bank‑linking, and staff training. With 17 separate steps required to activate a device, many merchants abandoned the technology before it could deliver any benefit.

The researchers tested two layers of assistance. First, a “customer success manager” visited stores twice, handled the technical setup, resolved connectivity issues, and trained employees. This alone lifted the share of working devices from roughly 40 % to 74 % and increased the proportion of merchants accepting at least one digital payment by about 20 percentage points. A second, more intensive package added promotional signage, small incentives and usage tracking, pushing adoption an additional 13 points and raising monthly digital transactions from three to over five per store. The structured onboarding cut the effective cost of gaining an active user by up to 63 %.

The findings reshape how governments and fintech firms should allocate resources. Rather than subsidizing cheap terminals, they should invest in hands‑on onboarding that simplifies the 17‑step activation process and educates both staff and customers. The spillover effect—untreated neighboring shops also adopting digital payments—suggests that targeted support can catalyze broader ecosystem change. Given that merchants who accept electronic payments earn roughly 57 % higher profits, scaling such assistance could accelerate financial inclusion and unlock significant economic gains across developing economies.
