Purpose: The study examines the relationship between donor funding models, organisational capacity, and project success among social enterprises in Ghana. It aims to determine how different funding approaches influence internal organisational capabilities and, in turn, project outcomes.

Methodology/Design: A quantitative research design was employed, using a structured questionnaire administered to 450 participants across various social enterprises. Structural Equation Modeling (SEM) was applied to analyse the relationships between donor funding models, organisational capacity, and project success.

Findings: The results indicate that donor funding models have a significant positive effect on organisational capacity (β = 0.58) and project success (β = 0.41). Organisational capacity also significantly influences project success (β = 0.62) and partially mediates the relationship between donor funding models and project outcomes (β = 0.36). These findings suggest that internal organisational strength enhances the effectiveness of donor funding in achieving project goals.

Implications: The study highlights the need for donor organisations to design funding models that support internal capacity building, and for social enterprises to invest in staff development, systems, and processes. Policymakers should promote frameworks that strengthen organisational capabilities to ensure sustainable project success.
