This chapter focuses on the topic of the coordination of marketing and sales activities in B2B organizations. It first provides a brief historical overview of the topic, including the recurring prescriptive advice that has been offered to practitioners and why this advice seems to have limited usefulness. This chapter then reviews some common delineations of marketing and sales activities in companies and their implications: both groups have inherent interdependencies and necessary differences. It concludes with a discussion of what some B2B companies have done to improve coordination between their marketing and sales functions, as well as some suggestions for further research.
