Resources are central to value creation processes. Hence, marketing and service research rely heavily on conceptualisations of resources and resource integration for theory building efforts. One of the most widely accepted marketing lenses on resources and resource integration is the service-dominant (S-D) logic. Depicting resources as becoming and contextual, S-D logic argues that their usefulness co-depends on other resources. Some assumptions of S-D logic have been challenged particularly its dichotomous categorisation of operand and operant resources. To inform ongoing S-D logic theorising, our article problematises the multiple and contradictory ontological views upon resources and resource integration present within S-D logic. Moving beyond critique, we propose concrete means for reconciling these contradictions. Seeing a parallel between S-D logic's ontological inconsistencies and past ontological disagreements in the philosophy of science, we draw on the philosophical perspective of Karen Barad to develop a consistent onto-epistemological foundation for conceptualising the becoming nature of resources in S-D logic. The theory adaptation we perform enhances the applicability and explanatory capacity of S-D logic, while also offering a more robust and rigorous foundation for marketing and service research at large and giving managers new means to make sense of co-dependent resource phenomena.
