The aim of this research was to identify quality discrepancies in the existing service offerings of logistics service providers (LSPs). A multi-sided model of service quality (SERVQUAL) highlighting existing gaps in service provision was developed. A qualitative case study approach was employed, and the data were analyzed via a pattern-matching technique. The contribution to the literature is twofold. First, the study transferred the original service quality model developed in the 1980s from a business-to-consumer context to a business-to-business context that is specific to LSPs. Second, the results provide a means of closing the identified service quality gaps arising in an LSP context.
