Foundations need to explain how entrusted resources support social purposes. This study examines associations of social accounting implementation and spiritual accounting orientation with organizational accountability, including indirect paths through reporting transparency, in social and educational foundations in Jakarta. A cross-sectional survey yielded 200 returns from 260 invitations; 150 respondent records were retained for partial least squares structural equation modeling. Social accounting was positively associated with transparency (β = .258) and accountability (β = .334), and spiritual orientation with transparency (β = .279) and accountability (β = .222). Transparency was associated with accountability (β = .191). Reported indirect coefficients were .049 and .053, with 95% bootstrap intervals [.011, .106] and [.013, .110]. Total coefficients calculated from rounded estimates were .383 and .275, with descriptive mediated shares of 12.8% and 19.3%. The model accounted for 20.0% of transparency variation and 33.3% of accountability variation; all local f² values were small. The findings are compatible with a limited statistical transparency pathway. Concurrent self-reports, undocumented reason-specific exclusions, provisional content validity, and unreported method-bias and indicator-level prediction diagnostics limit interpretation. The study does not establish causal mediation or rule out reverse causality.
