In modern marketing, the emergence of mass customization has reoriented the focus from traditional marketing practices toward a customer-centric approach. The individualization feel among consumers and the innovative approach taken by businesses are currently evident in the market but has yet been holistically analyzed. This study applied a modified Theory of Planned Behavior by incorporating the need for individualization, hedonic and utilitarian motivations, with a 4Ps marketing mix – with the main objective to identify factors contributing to the intention to make purchase of customized products. The survey involved 311 participants who completed an online questionnaire utilizing purposive sampling approach, focusing on those who had previously bought customized products. Structural Equation Modeling was employed as a statistical method to analyze the data with SPSS AMOS v25. Findings revealed that the need for individualization proved to have the highest effect on the intention to purchase customized products, explaining that consumers who are strongly inclined toward individualization not only perceive greater value in customized products but also express a higher intention to purchase them. This was followed by its direct significant effect on attitude, with an even higher effect on perceived behavioral control, along with the marketing mix latent variable and customer perceived value on purchasing intention. This study offers valuable insights for retail brand management and provides potential strategies for business improvement. Moreover, a valuable contribution to the limited literature on the promotion of customized product purchases was identified. Lastly, the developed framework and implications may be applied and extended by future research in the consumer behavior field.
