Purpose: The purpose of this paper is to examine the influence of the dialogue, access, risk assessment and transparency model of value co-creation processes (dialogue, access, risk and transparency) on new service market performance (NSMP) with the mediating role of value-informed pricing in the context of business-to-business (B2B). Design/methodology/approach: The data were collected through a cross-sectional survey of 230 managers of the telecommunications industry in Malaysia and analyzed through structural equation modeling using SmartPLS v.3.3.3 software. Findings: This study found that dialogue and transparency are predictors of NSMP. The findings indicate that value-informed pricing plays a mediating role in the relationship between dialogue and transparency with NSMP. Practical implications: Disclosing pricing related information, providing up to date information to the customers, making clear to the customers about new offerings would certainly influence value-informed pricing. Thus, managers can enhance customer engagement in the interaction processes to better understand customer expectations of new services and how the new services should be priced. Originality/value: The link between value co-creation and value-informed pricing has been only conceptualized in literature. This study has opened a new stream of research, examining the relationship of interactional-based value co-creation process with value-informed pricing and NSMP in the context of B2B relationship from providers’ perspective.
