They provide financial services to their members, fostering economic growth and reducing poverty. However, the extent of their impact on the socio-economic development of their beneficiaries remains under-explored. This research aims to investigate the influence of SACCOs, with a specific focus on the Zigama Credit and Saving Society, on the socio-economic development of their beneficiaries from 2018 to 2023.The researchwas guided by three specific objectives: To assess the impact of Saving Services provided by Zigama Credit and Saving Society on the financial well-being of its beneficiaries. To examine the influence of Credit Services offered by Zigama Credit and Saving Society on the socio-economic development of its beneficiaries. And to find out the effectiveness of Training programs conducted by Zigama Credit and Saving Society in enhancing the financial literacy and skills of its beneficiaries. This research considered three theories in its theoretical framework in particular and these include Cooperative theory, Financial Inclusion Theory and Social capital theory. Methods and Materials:For this study, a descriptive research designs were employed, and data were collected by using both quantitative and qualitative methods, using interview guides and questionnaires.A sample size of 398 individuals was selected from the broader staff population of 77,010members, beneficiaries and staff of Zigama CSS, following Taro Yamanes formula for sample size determination.The collected data were analysed through statistical analysis, encompassing descriptive measures such as the mean and standard deviation to provide an overview of the data. Additionally, inferential statistical techniques were be used, focusing on the application of the Pearson correlation coefficient (r) and multiple linear regression analysis. Results: The research findings revealed that Beneficiaries perceive ZigamaCSSs saving services positively, with high satisfaction regarding interest rates (Mean=4.44, Std=0.78), accessibility (Mean=4.47, Std=0.75), and incentives for saving (Mean=4.49, Std=0.73). The societys credit services are highly regarded, with strong agreement on loan accessibility (Mean=4.38, Std=0.73), reasonable interest rates (Mean=4.35, Std=0.79), flexible loan repayment terms (Mean=4.41, Std=0.71), transparent credit approval process (Mean=4.37, Std=0.75), and positive impact on socio-economic status (Mean=4.37, Std=0.77).
