<![CDATA[This study aims to explain why trust is necessary in inter-organizational logistics relationships and to identify the factors that support and inhibit its formation in the Indonesian context. A qualitative case study was conducted at FAB Enterprises. Data were obtained through semi-structured interviews with one logistics manager, one business partner, and two operational staff members, complemented by observations of interaction patterns. Informants were purposively selected for their direct involvement in inter-organizational relationships, partnership decisions, and coordination processes. Data were analyzed using thematic analysis through familiarisation, coding, theme development, review, definition, and interpretation. Trust emerged as a multidimensional construct combining cognitive elements—competence, reliability, consistency, and predictability—with affective elements such as mutual respect, interpersonal comfort, and relational closeness. Trust developed through repeated interactions, transparent communication, consistent performance, responsiveness, and accumulated experience. Reputation, recommendations, clear agreements, and shared goals accelerated early trust, whereas inconsistent performance, poor communication, lack of transparency, delays, broken commitments, and unmet expectations weakened trust. The Indonesian context further showed that informal relationships, harmony, and mutual respect complement formal contractual mechanisms. The findings indicate that trust operates simultaneously as a relational outcome, a governance mechanism, and a strategic intangible resource. Logistics managers should therefore combine formal safeguards with continuous relational practices, especially transparent communication, reliable performance, and relationship-building. The study contributes a context-sensitive explanation of how trust is formed and sustained in emerging-market inter-organizational logistics relationships.]]>
