In the marketing sector, this condition is characterized by increasingly fierce competition. Companies are required to adapt to diverse consumer preferences and needs. In the marketing process, several factors influence purchasing decisions, including store atmosphere, service quality, and product variety. This study aims to analyze the influence of store atmosphere and service quality on purchasing decisions, with product variety as a moderating variable. This study was conducted at the 3 Saudara Clothing Store in Tangerang Regency. The research population was all store visitors, with a sample of 155 respondents obtained using non-probability sampling techniques, specifically accidental sampling. Data collection was carried out through questionnaires, while data analysis used SmartPLS software version 4.0. The results of the study show: (1) Store atmosphere has a significant effect on purchasing decisions; (2) Service quality has a significant effect on purchasing decisions; (3) Product variety moderates the relationship between store atmosphere and purchasing decisions; and (4) Product variety moderates the relationship between service quality and purchasing decisions. These findings indicate that store atmosphere and service quality play a significant role in driving purchasing decisions, and this influence can be amplified through product diversity. Therefore, maintaining a comfortable and attractive store environment, improving service quality, and providing a wide product variety are important strategies for retail stores in facing increasingly competitive markets.]]>
