Small and Medium Enterprises (SMEs) make up the vast majority of businesses in most countries. Corporate communication is one of the functions that has not been well examined in small and medium enterprises. In order to gain a deeper understanding of corporate communication in small and medium enterprises this study reviewed literature of corporate communication and analyzed corporate communication operations in selected cases. The objective is to learn the advantages, challenges, and actual practice of corporate communication in small and medium enterprises in Taiwan. Based on cross-case analysis, the study results show that the advantages of corporate communication are enhanced branding, increased customer base, positive society acceptance, and improved recruitment. It is important to note that corporate communication is a management discipline rather than technical proficiency. In real practice, corporate communication tends to be neglected in daily operations due to difficulties in measuring the return on investment.
