Influence of Supplier Integration on Inventory Efficiency in Manufacturing Firms in Cross River State, Nigeria

Abstract

This study examined the influence of supplier integration on inventory efficiency in manufacturing firms located in Cross River State, Nigeria. Supplier integration was explored through five thematic dimensions: communication and information sharing, collaborative planning and decision-making, technological support, barriers to integration, and strategies for improvement. A qualitative research design was adopted to capture the lived experiences and operational practices of six purposively selected participants drawn from various manufacturing sectors including agro-allied, plastic packaging, paint production, and building materials. Data were collected using semi-structured interviews and analyzed thematically. The findings revealed that ineffective communication, lack of joint planning, poor technological infrastructure, and supplier informality were major challenges undermining inventory efficiency. Most firms operated in isolation from their suppliers, resulting in stock inconsistencies, planning errors, and increased operational costs. However, firms that adopted performance scorecards, collaborative forecasting, and selective supplier engagement practices reported notable improvements in inventory alignment and responsiveness. The study concludes that supplier integration, when properly structured and supported with the right technology and relationship frameworks, can significantly improve inventory control, minimize waste, and enhance competitiveness. It recommends the institutionalization of digital platforms, supplier capacity-building programs, long-term partnership contracts, and government-led incentives to promote stronger supplier-manufacturer collaboration in the Nigerian manufacturing landscape.
