ABSTRACT : Cash flow management is commonly viewed as a technical mechanism for maintaining liquidity. Within hybrid cooperative organizations, however, financial decisions are negotiated through solidarity, moral responsibility, and collective legitimacy. This study examines how actors in Koperasi Karyawan Kaltim Prima Coal (K3PC) managed cash flow amid prolonged payment delays and liquidity disruption. Using an ethnomethodological approach, data were collected through interviews, observation, and document analysis. Findings reveal that actors sustained organizational continuity through payment prioritization, rescheduling, informal negotiation, and solidarity-based financing. These practices were continuously shaped by reflexive moral evaluation and collective accountability. The study proposes the Solidarity-Based Cash Flow Management model, explaining a continuous reflexive cycle linking moral meaning construction, adaptive cash flow practices, Moral Financial Tension (MFT), reflexive organizational evaluation, and reconstructed moral meaning. The findings contribute to interpretive accounting and hybrid organization literature by conceptualizing cash flow management as a socially accountable organizational accomplishment rather than a purely technical financial mechanism.
