EFFECT OF INVENTORY MANAGEMENT SYSTEMS ON THE PERFORMANCE OF SMALL AND MEDIUM ENTERPRISES (SMEs)

Background to the Study

Inventory constitutes one of most significant assets any business enterprise whether small medium large effective management continued occupy central place operations business management literature. Inventory management refers systematic process ordering storing tracking controlling firm's stock raw materials work-in-progress finished goods manner that balances cost holding inventory against cost stock-outs so as ensure smooth continuous operations per Coyle Langley Novack & Gibson 2017. For SMEs which typically operate with limited capital thin profit margins constrained access to credit manner inventory planned ordered stored disposed has direct often immediate effect liquidity profitability overall survival. SMEs occupy strategic position economies both developed developing nations. In Nigeria SMEs estimated by SMEDAN NBS account for over 96% registered businesses contribute nearly 50% nation's GDP provide employment substantial proportion working population per SMEDAN/NBS 2021. Despite strategic importance SMEs Nigeria continue record high mortality rate several studies attributing this partly to poor inventory working-capital management practices alongside challenges infrastructure finance multiple taxation per Ibrahim Shariff & Ahmad 2020. Historically many SMEs Nigeria including Benin City Edo State relied manual largely informal inventory management practices periodic physical counting handwritten stock cards personal judgement to manage stock. While such approaches may suffice very small operations narrow product range become increasingly inadequate as businesses grow transaction volume product variety often resulting stock-outs overstocking spoilage pilferage ultimately avoidable losses. Proliferation relatively affordable inventory management software point-of-sale POS systems barcoding mobile-based stock applications recent years created opportunity for SMEs modernise inventory practices and by extension improve overall performance per Atnafu & Balda 2018. Relevance sound inventory practice further heightened by peculiar operating environment Nigerian SMEs characterised volatile input prices currency fluctuation irregular power supply and in many cases limited access formal bank credit. Under such conditions capital tied up excess slow-moving inventory represents particularly costly inefficiency since SMEs typically cannot rely cheap short-term borrowing to bridge working-capital gaps created poor stock decisions. Conversely inadequate stock-holding exposes SMEs to lost sales reputational damage highly competitive local markets where customers can easily switch to nearby competitor. Dynamics make study inventory management practices consequences firm performance matter both academic immediate practical significance for SME operators in Benin City. Past decade witnessed gradual but uneven diffusion digital tools into Nigerian SME operations spurred by broader growth mobile telephony financial technology fintech services e-commerce. Point-of-sale terminals once associated almost exclusively banks large retailers become commonplace even among small traders largely due utility cashless payment acceptance. However extent broader digital diffusion extended specifically to inventory management as opposed payment processing alone and extent such adoption where exists translates measurable performance gains remains empirical question study designed to address within Benin City context.

Statement of the Problem

Despite acknowledged importance inventory management to business performance substantial number SMEs Nigeria including Benin City continue grapple with inventory-related challenges. Anecdotal evidence preliminary observations suggest many SME operators still rely manual stock-taking memory-based reordering informal record-keeping which frequently result stock-outs fast-moving items overstocking slow-moving items tied-down working capital spoilage perishable goods difficulty detecting theft pilferage. These inefficiencies translate into lost sales dissatisfied customers erosion profit margins and in extreme cases business closure. While large firms increasingly adopted sophisticated Enterprise Resource Planning ERP computerised inventory management systems to mitigate problems extent SMEs constrained limited capital low technical capacity and in some cases poor awareness have adopted such systems and actual effect whatever inventory management practices they use on their performance remains empirically under-investigated in specific context Benin City. Furthermore although number studies examined inventory management organisational performance Nigeria many focused on large manufacturing firms or conducted other geo-political zones creating contextual geographical gap regarding SMEs operating within Edo State. It is this gap knowledge specifically paucity empirical evidence on how inventory control techniques record-keeping systems technology adoption jointly individually affect performance SMEs in Benin City that study seeks to fill.

Significance of the Study

Significant to several categories stakeholders. To SME owners managers findings provide empirical evidence practical insight how specific inventory management practices influence business performance thereby guiding more informed decisions on adoption inventory control techniques technology. To policy makers support agencies such as SMEDAN Bank of Industry Edo State Ministry Commerce Industry study offers evidence that can inform design targeted capacity-building technology-subsidy programmes for SMEs. To academic community contributes growing body literature on inventory management SME performance particularly providing context-specific evidence from Benin City Edo State area received comparatively limited empirical attention prior studies. For SME owners managers offers diagnostic lens through which may assess current inventory practices against empirically validated performance drivers potentially prompting re-evaluation long-standing but inefficient stock-management habits. Comparative evidence manual versus computerised systems in particular provides concrete locally-grounded business case owners can weigh when deciding whether cost technology adoption justified by expected performance return. For SMEDAN Edo State Ministry Bank Industry identification capital skills infrastructure as dominant barriers rather than lack awareness offers more precise basis designing intervention programmes. To researchers students study adds to still-developing stream Nigerian SME literature by providing methodologically rigorous context-specific empirical account from Benin City and by explicitly testing comparative performance effect manual versus computerised inventory systems.

Scope of the Study

Delimited to registered SMEs operating within Benin City metropolis Edo State Nigeria cutting across trading retail/wholesale manufacturing/production and service sub-sectors. Content scope covers three broad dimensions inventory management inventory control techniques inventory record-keeping systems inventory technology adoption and their effect on SME performance measured profitability sales growth operational efficiency. Study cross-sectional relying on data collected within 2025/2026 academic session period. Sample 210 owners managers Taro Yamane stratified random validated questionnaire Cronbach 0.84.

Limitations

Constrained by number factors. First some SME operators reluctant disclose financial operational information considered sensitive although mitigated by assuring confidentiality anonymity. Second relied on self-reported perceptual data rather than audited financial records which may introduce subjectivity however moderated by triangulating perceptual performance measures with observable indicators such as sales growth trends. Third time financial constraints limited geographical scope Benin City metropolis which may affect generalisability findings to SMEs other parts Nigeria with different economic infrastructural realities. Reasonable steps taken ensure findings remain valid reliable within defined scope.
