"Pay It Forward" campaign was designed to address the financial instability faced by Mexico’s 1.1 million "tiendas de barrio," which account for half of Indio’s sales but face a 32% closure rate within their first year. These vital community hubs lacked access to formal financial services, relying instead on "tandas," informal savings groups that are often unreliable and difficult to maintain. The campaign transformed Heishop, Indio’s ordering platform, into a modernized, data-driven version of "tandas." Using transactional data, shopkeepers were grouped based on purchasing habits and payment reliability, ensuring trust and compatibility. Contributions were seamlessly integrated into the ordering process, with Indio providing additional support to cover missed payments. Hyper-localized ads featuring shopkeepers amplified engagement and loyalty within their communities. The campaign successfully saved 15% of stores from closure, increased Indio Beer sales by 69.9%, and achieved a 91% participation rate among shopkeepers, empowering communities and strengthening Indio’s market leadership.
