This study examined the effect of sourcing procedures on the export performance of selected coffee export private limited companies (PLCs) in Addis Ababa, Ethiopia. It specifically investigated the effects of supplier selection and evaluation, quality control procedures, supplier relationship management, and logistics and storage practices on export performance. An explanatory research design with a quantitative approach was employed. The study used primary data collected through structured questionnaires from employees and managers of selected coffee export PLCs. A two-stage simple random sampling technique was applied to select firms and respondents, and the final sample consisted of 367 valid responses. Data were analyzed using Pearson correlation and multiple linear regression analysis. The findings revealed that all four sourcing procedures have a statistically significant and positive effect on export performance (p < 0.001). Quality control procedures emerged as the strongest predictor (β = 0.523), followed by supplier selection and evaluation (β = 0.278), supplier relationship management (β = 0.133), and logistics and storage practices (β = 0.113), indicating that effective sourcing management significantly enhances export performance. Based on the findings, the study recommends that coffee export firms strengthen internal quality control systems through certified Q-graders and standardized cupping procedures, adopt structured supplier evaluation checklists to improve procurement decisions, establish long term contractual relationships with suppliers supported by technical assistance and pre financing, and improve logistics and storage systems through better packaging, moisture control, and shipment monitoring. Overall, the study concludes that integrated sourcing practices collectively determine export performance rather than any single factor alone.
