The aim of this Special Issue is to advance our understanding of performance-based contracting (PBC) in business markets. PBC has the potential for aligning incentives among buyers and sellers and fostering innovation. This paper critically reflects on extant research in order to develop a systematic knowledge map of PBC research. On that basis four major research gaps are identified and addressed, drawing out specific avenues for further PBC research. The knowledge map is also used to illustrate the focus and main arguments of the articles featuring in this Special Issue.
