The current research highlights the challenges faced by Nigerian small and medium-sized enterprises (SMEs) in the agricultural sector when it comes to internationalization. The SMEs need to adapt to new business policies, technologies, and cultural differences to avoid legal complexities and interruptions to their operations. The study identifies several barriers to internationalization, including knowledge, social and cultural, technological, economic, and organizational barriers. To overcome these challenges, the research recommends that Nigerian SMEs invest in e-commerce technologies, market research, and financial resources to improve service delivery and reach international customers. It also emphasizes the importance of organizational readiness, which includes identifying risks, accepting changes, and adopting new technologies. By understanding these challenges and implementing effective strategies, Nigerian agricultural SMEs can successfully internationalize and contribute to national growth.
