The emergence of Buy Now, Pay Later (BNPL) services has significantly influenced modern consumer purchasing patterns, particularly in retail environments. This study explores the effectiveness of BNPL services in shaping consumer purchasing behavior within offline retail shops in Coimbatore. With the growing popularity of deferred payment options, it becomes essential to understand how BNPL impacts customer satisfaction, purchase decisions, and loyalty in a physical retail context. Data was collected through a structured questionnaire distributed among 226 consumers who have used BNPL services in offline retail settings. Key variables, including satisfaction levels and willingness to recommend BNPL services, were analyzed using correlation techniques. The findings reveal a weak and statistically insignificant relationship between customer satisfaction with BNPL in offline retail and their likelihood to recommend it to others. This suggests that while BNPL may enhance purchasing power, its influence on customer advocacy may be limited in the offline retail space. The study offers insights for retailers and financial service providers aiming to refine BNPL offerings and align them with consumer expectations in local markets like Coimbatore.
