The purpose of this study is to establish the relationship between buyer-supplier collaboration, supplier induced corruption, contractual governance mechanisms, supplier opportunistic behavior, buyer-supplier trust and supplier delivery performance in central government Procuring and disposing entities (PDEs) contracts in Kampala. Despite buyer-supplier collaboration being expected to increase buyer-supplier trust over time, minimize supplier opportunistic behavior and the related transaction costs. This is not the case in Uganda. Instead, as the public procurement officers collaborate more with suppliers, corruption practices have increased. Supplier induced corruption has gained volume and momentum, with suppliers facilitating exchanges with bribes which have resulted in supplier favors and influences. This has adversely affected supplier delivery performance of contracts. A cross sectional and correlational survey was conducted using a sample of 121 PDEs from a population of 175 entities and data was collected from respondents using a self-administered questionnaire. Findings reveal that: buyer-supplier collaboration, supplier induced corruption, buyer-supplier collaboration, supplier opportunistic behavior, contractual governance mechanisms and buyer-supplier trust are significant predictors of supplier delivery performance. The results of this study have managerial and theoretical implications which are also discussed
