The crucial purpose of the paper is to present the outcomes of the analysis concerning the effects of technological solutions of Logistics 4.0 on logistics resources and customer service in freight transport enterprises. The paper identifies four core and seven emergent technologies of Logistics 4.0 as catalysts for the enhancement of logistics customer service in the freight transport sector. Empirical data were acquired from 460 freight transport enterprises located in Poland through the application of a survey methodology. Within the adopted research framework, confirmatory factor analysis was conducted initially, followed by the application of Structural Equation Modelling using the Partial Least Squares (SEM-PLS) approach, with a post hoc analysis subsequently performed to identify patterns of similarity in the observed effects. It has been demonstrated that both core and emerging technologies of Logistics 4.0 within freight transport enterprises constitute valuable instruments facilitating access to critical information relevant to logistics customer service. Simultaneously, findings suggest that emerging technologies of Logistics 4.0 in service-related benefits are conditional, temporally delayed, and strongly dependent on implementation depth, organisational readiness, and systemic integration. Additionally, the analysis revealed that logistics resources serve as a mediating variable in the relationship between both core and emerging Logistics 4.0 technologies and logistics customer service.
