The purpose of this study was to investigate the impact of inventory levels on customer service, innovativeness and demand flexibility of petroleum depots in Rivers State. This study was anchored on two supply chain management theories. Data were collected through well-structured questionnaire from eighty (80) managers drawn from sixteen (16) petroleum depots in Rivers State. The data collected were analysed using multiple regression to measure the relationships between (inventory management) and the measures of (supply chain performance) which include customer service, innovativeness and demand flexibility with the aid of the statistical package for social science (SPSS) version 25.0. Hence, the analysis revealed that there is very strong, strong, positive and significant relationship between the variables. Based on the above findings, we therefore conclude that inventory management has great effects on supply chain performance of petroleum depots in Rivers State. Inventory management enhances customer service, innovativeness and demand flexibility. As a result, recommends that, management of petroleum depots should try as much as required to maintain optimal inventory level (not holding excess stock and not holding too few inventory) so as to reduce their frequent irregular supply of petroleum products and always stock out, as a result increasing their level of supply chain performance. Also, the study recommends that petroleum depots should strengthen processes, and automated systems (innovativeness) that will shorten their lead time and as well as improving customer satisfaction and loyalty by ensuring timely delivery of petroleum products, always availability of products in order to avoid stock outs and its disadvantages which most times causes the customers look elsewhere.
