The context of this study is Bangladesh`s food retailing sector. The main purpose of this study is to investigate the relationship between Customer Relationship Marketing (CRM) and customer retention. The core aim of Relationship Marketing is to build long lasting mutually bonded relationships with customers and various other important stakeholders. The concept has attracted considerable attention among scholars in recent decades and has appeared in service marketing literature as a new marketing paradigm. The concept is critical to the success of any organisation as it has been an accepted phenomenon that maintains that existing customers are far easier to retain than is the process of acquiring new customers. In order to stay in business and cope with the challenging business dynamism, organisations are continuously searching for reliable and serviceable strategies to be employed in order to increase customer retention. However, there is a lack of consensus among researchers on the core antecedents of relationship marketing that can be used to achieve the above aims, especially while the concept is new in the context of organised retailing sectors in Bangladesh. In response, the study developed a conceptual framework of customer retention strategy which incorporates bonds, service quality and relational quality into one relationship model. The model establishes eleven hypotheses. A sample of 202 grocery food retail customers were selected in a random sample from four selected superstores. The results support hypothesized relationships built on the model. The findings indicate that service quality, trust, bond and customer satisfactions are vital for creating positive customer loyalty which in turn creates customer retention.
