This study aimed to: (1) examine the level of good governance-based budget management in original equipment manufacturer (OEM) health and beauty dietary supplement industries operating within local administrative areas of Samut Sakhon Province; (2) examine the effects of good governance principles, Carbon Credit integration, and Environmental, Social, and Governance (ESG) practices on financial and accounting operational efficiency; and (3) develop guidelines for governance-based budget management to enhance financial and accounting performance and sustainable corporate governance. A mixed-methods research design was employed. The quantitative component involved 385 executives, financial and accounting managers, and relevant personnel from OEM health and beauty dietary supplement enterprises, selected through purposive sampling. Data were collected using a structured questionnaire, while qualitative data were obtained through semi-structured interviews and an appropriateness assessment of the proposed guidelines. Quantitative data were analyzed using descriptive and inferential statistics, whereas qualitative data were analyzed through content analysis. The findings indicated that the overall level of good governance-based budget management was high. Transparency, accountability, participation, and value for money were identified as key dimensions associated with financial and accounting operational efficiency. Good governance principles, Carbon Credit integration, and ESG practices had statistically significant positive effects on financial and accounting performance at the .05 significance level. The qualitative findings further supported the development of an integrated budget management framework incorporating good governance, risk management, Carbon Credit management, and ESG practices. The proposed framework provides practical guidance for improving budget administration, financial and accounting efficiency, transparency, and sustainable corporate governance in OEM health and beauty dietary supplement industries. The study contributes an integrated governance-based budget management framework that connects financial management with environmental and sustainability principles.
