Project – Working Capital Management and Profitability of Small and Medium-Sized Enterprises: A Study of Selected Businesses in Onitsha Metropolis, Anambra State

CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Small and medium-sized enterprises (SMEs) constitute an important segment of the Nigerian business environment and play a significant role in employment generation, income creation, innovation, distribution of goods and services, and local economic development. Their importance is particularly relevant in developing economies where large formal-sector organisations may not be sufficient to absorb the growing labour force. The 2021 National MSME Survey reported that Nigeria’s micro, small and medium enterprises accounted for 46.32 percent of national GDP, 6.21 percent of exports, 96.9 percent of businesses and 87.9 percent of employment, demonstrating the substantial contribution of the sector to the national economy (SMEDAN & NBS, 2021). These figures underscore the need to examine the financial practices that determine the survival, growth and profitability of SMEs.

The importance of SMEs to economic development extends beyond their numerical strength. SMEs provide opportunities for entrepreneurship and self-employment, facilitate the movement of goods and services and serve as an avenue through which individuals and households generate income. In Nigeria, the sector also contributes to the development of entrepreneurial capabilities and provides a foundation for business expansion. Studies of Nigerian entrepreneurship have linked the development of small and medium-sized businesses with economic growth and employment creation, indicating that the performance of these enterprises has implications for the broader economy (Oladimeji & Aladejebi, 2020).

Despite their importance, SMEs operate within an environment characterised by numerous financial and operational constraints. These include inadequate access to finance, fluctuations in demand, increasing operating costs, infrastructure challenges, intense competition, limited managerial capacity and difficulties in maintaining adequate liquidity. Recent evidence from the Nigerian MSME sector continues to identify access to finance, changing market conditions and macroeconomic pressures as major concerns affecting business performance (PwC, 2024). Such challenges make effective financial management particularly important because SMEs generally have fewer financial buffers than large corporations.

One of the most important areas of financial management for an SME is working capital management. Working capital generally concerns the management of current assets and current liabilities required for the day-to-day operation of a business. Current assets commonly include cash, inventories and trade receivables, while current liabilities include trade payables and other short-term obligations. Working capital management therefore involves determining the appropriate amount of resources to maintain in these accounts and ensuring that they are efficiently managed. Gitman and Zutter (2015) treat working capital and current asset management as a major component of short-term financial decision-making, reflecting its importance to business operations and financial performance.

Working capital management is particularly important for SMEs because a substantial proportion of their resources may be committed to current assets, while short-term liabilities may constitute an important source of financing. Smaller businesses may also experience greater difficulty accessing long-term capital markets and formal sources of finance. Consequently, inefficient management of inventories, receivables, cash and payables can quickly create liquidity problems and affect the ability of the business to meet its short-term obligations. Adediran et al. (2012) specifically emphasised the importance of working capital management to Nigerian SMEs because of their financing constraints and dependence on current resources for business operations.

The central objective of working capital management is to achieve an appropriate balance between liquidity and profitability. Excessive investment in current assets may reduce profitability because funds remain tied up in inventories, receivables or idle cash rather than being invested productively. On the other hand, inadequate working capital may expose an enterprise to liquidity problems, delayed payments, stock shortages and loss of business opportunities. Atrill (2017) recognises working capital management as a major area of financial decision-making and emphasises its relationship with the efficient operation and financial health of businesses.

Cash management constitutes an important component of working capital management. Businesses require sufficient cash to pay employees, suppliers, creditors, utility providers, transport operators and other stakeholders. However, maintaining excessive idle cash may involve an opportunity cost because funds that could have generated returns elsewhere remain unproductive. Effective cash management therefore requires an enterprise to maintain sufficient liquidity while avoiding unnecessary accumulation of idle funds. Gitman and Zutter (2015) identify cash management as an important aspect of current asset management and short-term financial decision-making.

Inventory management is another major component of working capital management. Inventory represents resources committed to goods held for sale or materials required for production and business operations. Excessive inventory may increase storage costs, insurance costs, deterioration and obsolescence, while inadequate inventory may result in stock-outs, lost sales and dissatisfied customers. Efficient inventory management therefore requires SMEs to maintain stock at a level that supports uninterrupted business operations without unnecessarily tying up financial resources. Adediran et al. (2012) found evidence that reducing the number of days inventory was held could contribute to improved profitability among Nigerian SMEs.

Trade receivables are also central to working capital management, especially for businesses that sell goods or services on credit. Granting credit can encourage sales and strengthen customer relationships, but excessive credit sales or weak collection procedures may result in funds being tied up in unpaid invoices. When customers delay payment, the business may experience cash shortages even when sales appear high. Adediran et al. (2012) found that reducing the number of days of accounts receivable was associated with improved profitability among Nigerian SMEs, suggesting that efficient credit and collection policies are important for financial performance.

The management of trade payables is equally important. Businesses frequently obtain goods and services from suppliers on credit, thereby creating short-term obligations. Appropriate management of accounts payable allows an enterprise to use supplier credit as a source of short-term financing without unnecessarily damaging relationships with suppliers or incurring avoidable penalties. Tsagem et al. (2015) found a statistically significant relationship between accounts payable period and profitability among Nigerian SMEs, highlighting the importance of effective management of short-term obligations.

The cash conversion cycle provides a comprehensive way of assessing the efficiency with which a business converts resources invested in inventories and receivables back into cash. It generally reflects the period between payment for inventory or inputs and the collection of cash from customers. A lengthy cash conversion cycle can mean that substantial funds remain tied up in business operations for a prolonged period. Conversely, a shorter and efficiently managed cycle may release funds for other productive purposes. Adediran et al. (2012) found that shortening the cash conversion cycle improved the profitability of the Nigerian SMEs examined in their study.

Profitability represents the ability of a business to generate earnings from its operations and resources. It is an important indicator of business performance because persistent profitability provides the resources required for business survival, expansion, reinvestment and owner returns. Profitability may be assessed through measures such as return on assets, return on investment, gross profit margin and net profit margin. Brigham and Ehrhardt (2017) identify profitability and efficient financial management as important considerations in assessing the financial performance and value of business organisations.

For SMEs, profitability is particularly important because sustained profits can provide internally generated funds for business expansion and reduce dependence on external financing. A profitable business can replenish inventory, meet short-term obligations, replace equipment, employ additional workers and respond to market opportunities. Conversely, persistent low profitability can weaken the financial position of the enterprise and increase the likelihood of business failure. This makes the identification of factors capable of improving SME profitability an important issue for researchers, entrepreneurs and policymakers.

The relationship between working capital management and profitability is not necessarily straightforward because working capital decisions involve trade-offs. For example, maintaining a large inventory may reduce the risk of stock-outs and enable a business to meet customer demand, but it may simultaneously increase storage and financing costs. Similarly, granting generous credit terms may increase sales but could delay cash collection. Effective working capital management therefore requires managers to balance operational requirements with financial efficiency (Atrill, 2017).

Theoretical and empirical financial-management literature suggests that the manner in which managers handle current assets and current liabilities can influence profitability. Where inventories are converted rapidly into sales, receivables are collected promptly and payables are managed strategically, funds may circulate more efficiently through the business. On the other hand, inefficient working capital policies may result in excessive financing costs, bad debts, obsolete inventories and liquidity pressures. These considerations make working capital management an important determinant of financial performance (Gitman & Zutter, 2015).

Evidence from Nigeria supports the relevance of this relationship. Adediran et al. (2012), using data from 30 Nigerian SMEs, examined the relationship between working capital management and profitability and found that reducing accounts receivable days, inventory days and the cash conversion cycle was associated with improved profitability. Their findings suggest that SME managers can create value through more efficient management of short-term resources.

Similarly, Tsagem et al. (2015) examined Nigerian small and medium-sized entities and found significant relationships involving accounts receivable period, accounts payable period and cash conversion efficiency and profitability. The study recommended greater managerial attention to the efficient management of receivables, payables, inventories and cash. This finding reinforces the argument that working capital decisions are not merely routine accounting matters but can have important implications for the financial performance and sustainability of SMEs.

Further evidence is provided by Tsagem, Aripin and Ishak (2016), who analysed panel data from 311 Nigerian SMEs covering the period 2007–2013. Their findings showed statistically significant relationships between accounts receivable period, cash holdings, cash conversion efficiency and profitability measured by return on assets. The study suggested that SME owners and managers should optimise individual working capital components in order to improve profitability, liquidity and financing capacity.

However, empirical evidence is not completely uniform. Oladimeji and Aladejebi (2020), using data from selected Nigerian small businesses for 2014–2018, reported that their analysis did not establish a relationship between working capital management and profitability during the period studied. This contrasting evidence is important because it indicates that the effect of working capital management may depend on the characteristics of the enterprises, industry, period, managerial practices and economic environment under consideration.

Other Nigerian studies have also produced evidence of a relationship between working capital management and profitability in different business settings. Kajola et al. (2018), for example, examined 25 Nigerian listed non-financial firms and found that average collection period, inventory turnover period and cash conversion cycle significantly influenced profitability. Although the study focused on listed firms rather than SMEs, its findings reinforce the broader financial-management proposition that the efficiency with which short-term resources are managed can affect business profitability.

The relevance of working capital management is also reflected in evidence from Nigerian SMEs operating in different geographical contexts. Tony-Obiosa and Ibama (2021), in a study of SMEs in Rivers State, reported a positive and significant relationship between selected measures of working capital management and profitability. Their findings demonstrate that working capital practices can influence profitability within the Nigerian SME environment, although differences between locations make it important to investigate specific business environments independently.

The issue is particularly relevant to businesses operating in Onitsha because the metropolis is one of the important commercial centres in southeastern Nigeria. Businesses in Onitsha operate across trading, wholesale, retail, manufacturing, services and other commercial activities, creating an environment in which inventory acquisition, credit sales, supplier financing and cash management are central to daily operations. Recent research specifically examining entrepreneurship in Onitsha has identified the city’s commercial and industrial character and investigated financial factors affecting business performance (Onye & Anah, 2026).

Onitsha businesses may therefore face working capital challenges that are closely connected with the nature of commercial activities in the metropolis. Traders may need substantial funds to maintain adequate stock, while credit sales can create significant receivables. At the same time, businesses may have to settle suppliers, workers, transport providers, landlords and other obligations within relatively short periods. The ability to synchronise cash inflows and cash outflows is therefore crucial to business continuity and profitability.

The business environment in Onitsha is also influenced by broader economic conditions. Changes in purchasing power, inflation, exchange rates, financing costs and operating expenses can affect the amount of working capital required by businesses. PwC’s 2024 MSME survey identified macroeconomic pressures, financing constraints and changing market conditions as important issues shaping the Nigerian MSME sector. These pressures make efficient working capital management even more important for businesses attempting to maintain profitability in a changing economic environment.

Access to external finance further strengthens the importance of working capital management for SMEs. Small businesses may face difficulties obtaining affordable formal financing because of collateral requirements, lending procedures, limited financial records and perceived credit risks. When external finance is constrained, businesses must rely more heavily on internally generated funds and efficient management of existing resources. Research on entrepreneurship in Onitsha has similarly identified sources of capital and credit conditions as important issues affecting entrepreneurial performance in the metropolis (Onye & Anah, 2026).

Poor working capital management can have several negative consequences for SMEs. Excessive investment in inventory may cause funds to remain idle, while slow collection of receivables can restrict cash availability. Failure to manage payables appropriately may damage relationships with suppliers, while inadequate cash reserves may make it difficult to meet urgent financial obligations. Sunday (2011) observed that Nigerian SMEs may experience overtrading and illiquidity when working capital is not appropriately managed and emphasised the importance of credit policies and financial controls for business continuity and solvency.

In contrast, efficient working capital management can enhance operational efficiency and profitability. Prompt collection of receivables releases funds for reinvestment, appropriate inventory levels reduce unnecessary financing and storage costs, and strategic management of payables can preserve cash without undermining supplier relationships. Effective cash management can also ensure that businesses remain liquid enough to meet obligations while minimising idle funds. These practices collectively contribute to more efficient use of financial resources (Gitman & Zutter, 2015; Atrill, 2017).

The significance of this issue is heightened by the high failure vulnerability of smaller enterprises. Unlike large corporations, SMEs often have limited access to capital markets, smaller financial reserves and a narrower capacity to absorb unexpected financial shocks. A relatively small disruption in cash flow can therefore create serious operational difficulties. Effective working capital management can provide an important financial buffer by ensuring that cash, inventories, receivables and payables are appropriately coordinated.

Another important issue is the relationship between liquidity and profitability. A business may have a high level of current assets and therefore appear financially liquid, but excessive liquidity may indicate that resources are not being used productively. Conversely, an enterprise may report attractive profits but experience cash-flow problems because profits have not yet been converted into cash. Effective working capital management attempts to balance these two dimensions by ensuring that the enterprise remains sufficiently liquid without sacrificing profitability (Atrill, 2017).

The importance of working capital management is therefore not limited to accounting calculations. It involves managerial decisions concerning customer credit, inventory purchasing, supplier relationships, cash reserves, short-term borrowing, payment schedules and investment of temporary excess funds. These decisions can affect both the daily survival of an enterprise and its long-term financial performance. Brigham and Ehrhardt (2017) similarly treat working capital management as part of the broader financial management process through which organisations manage resources and financial decisions.

Although several studies have investigated working capital management and profitability among Nigerian businesses, relatively fewer studies have focused specifically on selected SMEs in Onitsha Metropolis, Anambra State. Existing Nigerian studies have examined national samples, listed firms, SMEs in other states and other specific business environments. For example, studies have examined SMEs nationally (Adediran et al., 2012), SMEs in the North-West (Tsagem et al., 2015), SMEs in Rivers State (Tony-Obiosa & Ibama, 2021), and businesses in other locations. The geographical and operational differences among these settings create a need for context-specific research in Onitsha.

The need for such a study is further strengthened by the fact that empirical findings on working capital management and profitability are mixed. While some studies report positive or significant relationships, others have found weak or insignificant relationships. Adediran et al. (2012) reported that shorter receivables, inventory periods and cash conversion cycles improved profitability, while Oladimeji and Aladejebi (2020) found no relationship between working capital management and profitability over their study period. Such differences indicate that the relationship may vary according to firm characteristics and operating environments.

Therefore, investigating working capital management among selected businesses in Onitsha Metropolis is important for establishing whether effective management of cash, inventory, receivables, payables and the cash conversion cycle is associated with improved profitability in that specific commercial environment. Such evidence may help explain how SME operators in Onitsha can improve the use of scarce financial resources and strengthen the sustainability of their businesses.

Against this background, this study examines working capital management and profitability of small and medium-sized enterprises, with particular reference to selected businesses in Onitsha Metropolis, Anambra State. The study focuses on major working capital components, including cash management, inventory management, accounts receivable management, accounts payable management and cash conversion cycle, and examines their relationship with profitability. The study is expected to contribute empirical evidence to the literature and provide useful information for SME owners, managers, financial practitioners, policymakers and future researchers.

1.2 Statement of the Problem

Small and medium-sized enterprises play a major role in Nigeria’s economy, yet many of them experience difficulties in achieving sustained profitability and business growth. The national importance of the sector contrasts with the financial and operational difficulties faced by individual enterprises. The 2021 SMEDAN/NBS survey shows the considerable contribution of MSMEs to employment and GDP, while more recent evidence identifies access to finance, macroeconomic pressures and changing market conditions as continuing challenges for the sector (SMEDAN & NBS, 2021; PwC, 2024).

One major problem is that SME operators may concentrate heavily on sales and revenue generation without giving sufficient attention to the manner in which current assets and current liabilities are managed. A business may generate substantial sales but still experience financial difficulty if customers do not pay promptly, inventories remain unsold or cash is inadequately managed. Sunday (2011) observed that poor working capital practices among Nigerian SMEs could contribute to overtrading and illiquidity and emphasised the need for appropriate credit and financial management policies.

Inventory management constitutes a particular problem because excessive stock ties up funds that could otherwise be used for other business purposes. At the same time, insufficient inventory may lead to stock-outs and lost sales. SMEs therefore need to determine an appropriate level of inventory that supports customer demand without unnecessarily immobilising scarce financial resources. Evidence from Adediran et al. (2012) indicates that reducing inventory holding periods can contribute to improved profitability among Nigerian SMEs.

Accounts receivable management also creates a significant problem for SMEs that operate on credit. Credit sales may be necessary to attract customers and remain competitive, but delayed payment can create cash-flow difficulties. When receivables accumulate, the enterprise may be forced to seek additional short-term financing to meet obligations, thereby increasing financing costs. Adediran et al. (2012) found that reducing accounts receivable days was associated with improved profitability, highlighting the importance of effective credit and collection policies.

Accounts payable creates another managerial challenge. SMEs may depend heavily on supplier credit because access to bank finance and other formal sources of funding can be constrained. However, excessive delay in paying suppliers can result in the loss of supplier confidence, withdrawal of credit facilities or deterioration of business relationships. Tsagem et al. (2015) found a significant relationship between accounts payable period and profitability among Nigerian SMEs, suggesting that payment policies can have important implications for financial performance.

Cash management presents an additional problem because SMEs must maintain sufficient funds to meet day-to-day obligations while avoiding excessive idle cash. Inadequate cash reserves may result in inability to pay suppliers, workers and other creditors when due, whereas excessive cash holdings may reduce the amount of funds available for productive investment. Tsagem et al. (2016) found a statistically significant relationship between cash holdings, cash conversion efficiency and profitability among Nigerian SMEs, demonstrating the importance of cash-related working capital decisions.

The cash conversion cycle is also a major concern because a prolonged cycle may indicate that funds remain tied up in inventory and receivables for too long. A business that pays suppliers before collecting cash from customers may experience persistent working capital shortages even when its sales volume is satisfactory. Adediran et al. (2012) found that shortening the cash conversion cycle improved profitability among the Nigerian SMEs studied, indicating that the speed with which working capital is converted back into cash can have financial consequences.

Another problem is the inconsistency of existing empirical evidence. While several studies have found significant relationships between working capital management and profitability, other studies have reported insignificant relationships. Oladimeji and Aladejebi (2020), for example, found no relationship between working capital management and profitability in their study of selected Nigerian small businesses during 2014–2018. This conflicting evidence makes it difficult to generalise findings across all Nigerian SMEs and creates the need for additional research in specific business environments.

The problem becomes more important in Onitsha Metropolis because of the city’s strong commercial orientation. Businesses in the metropolis engage in trading, wholesale, retail, manufacturing and services, many of which require continuous investment in inventories and involve credit relationships with customers and suppliers. Research specifically focused on entrepreneurship in Onitsha confirms the city’s commercial and industrial significance and shows that financing conditions are relevant to business performance in the area (Onye & Anah, 2026).

SMEs in Onitsha may also operate under conditions of fluctuating demand and changing operating costs. Rising costs of goods, transportation, energy, rent and other business inputs can increase the amount of funds required to maintain normal operations. Under such circumstances, inefficient working capital management can place additional pressure on already limited business resources. Recent Nigerian MSME evidence highlights macroeconomic pressures and changing market conditions as important challenges confronting small businesses (PwC, 2024).

The inability to obtain adequate external financing may further increase the problem. When SMEs cannot easily obtain affordable loans or other forms of external finance, their ability to maintain inventory, extend credit to customers and meet short-term obligations may depend heavily on internally generated cash. This makes the efficient management of working capital essential to their survival. Evidence from Onitsha also indicates that financing conditions and access to capital are relevant considerations in entrepreneurial performance within the metropolis (Onye & Anah, 2026).

Consequently, the central problem is that although working capital is essential to the daily operation of SMEs, inefficient management of its components may undermine profitability. Excessive inventory may tie up funds, slow receivables collection may create cash shortages, poorly managed payables may weaken supplier relationships, and inadequate cash management may affect the ability of businesses to meet immediate obligations. These conditions can reduce the financial efficiency and profitability of SMEs.

The existence of previous studies does not completely resolve the problem because most available evidence has been generated from different geographical locations, business sectors and methodological contexts. Studies conducted among Nigerian SMEs have produced different conclusions, and findings from national samples or other states may not accurately represent the working capital practices of SMEs operating in Onitsha Metropolis. The location-specific nature of business conditions therefore creates a research gap that requires empirical investigation.

There is therefore a need to establish whether effective management of cash, inventory, accounts receivable, accounts payable and the cash conversion cycle contributes significantly to profitability among selected SMEs in Onitsha Metropolis. Determining this relationship will help establish whether the financial difficulties experienced by businesses in the area may be partly associated with weaknesses in working capital management.

It is against this background that the present study investigates working capital management and profitability of small and medium-sized enterprises in Onitsha Metropolis, Anambra State. The study seeks to provide empirical evidence on the extent to which working capital management practices influence the profitability of selected businesses and thereby contribute to improved financial decision-making among SME operators.

1.3 Purpose of the Study

The general purpose of this study is to examine the relationship between working capital management and profitability of small and medium-sized enterprises in Onitsha Metropolis, Anambra State.

1.5 Research Hypothesis

The following null hypothesis will be tested at the 0.05 level of significance:

H₀: There is no significant relationship between working capital management and profitability of selected small and medium-sized enterprises in Onitsha Metropolis, Anambra State.

1.6 Significance of the Study

The study will be significant to owners and managers of small and medium-sized enterprises because it will provide information on how the management of short-term financial resources may influence profitability. The findings may enable SME operators to improve their decisions concerning cash balances, inventory levels, customer credit, supplier payments and short-term financing.

The study will also be beneficial to financial managers, accountants and business advisers who work with SMEs. It will provide empirical information that can assist professionals in advising businesses on appropriate working capital policies and practices.

The study will be useful to financial institutions because understanding the relationship between working capital management and profitability may provide additional insight into the financial behaviour and creditworthiness of SMEs. Banks and other lenders may find the findings useful when evaluating the financial management capacity of small businesses seeking credit facilities.

The study will also be relevant to policymakers and government agencies responsible for SME development. Evidence concerning working capital challenges may assist policymakers in designing financial education, business-development and support programmes aimed at improving the financial sustainability of SMEs.

The study will be beneficial to entrepreneurs in Onitsha Metropolis because the findings will be based specifically on businesses operating within their commercial environment. Entrepreneurs may use the findings to identify weaknesses in their current working capital practices and adopt strategies for improving liquidity and profitability.

The study will contribute to academic literature by providing additional empirical evidence on working capital management and SME profitability in Nigeria. It will also contribute location-specific evidence from Onitsha Metropolis, thereby helping to address the limited geographical coverage of some previous studies.

Finally, the study will serve as a reference material for future researchers who may wish to investigate working capital management, profitability, liquidity, SME financial performance, cash conversion cycles, inventory management, credit management or related areas.

1.7 Scope of the Study

The study focuses on working capital management and profitability of selected small and medium-sized enterprises in Onitsha Metropolis, Anambra State.

The study will examine major components of working capital management, including cash management, inventory management, accounts receivable management, accounts payable management and cash conversion cycle.

Profitability will be examined in terms of the ability of the selected enterprises to generate satisfactory financial returns from their business operations. Depending on the availability of information from respondents, indicators such as profit margin, return on investment and perceived profitability may be considered.

The geographical scope of the study is limited to selected SMEs operating within Onitsha Metropolis, Anambra State. The study does not cover all businesses in Anambra State or all SMEs in Nigeria.

1.8 Delimitation of the Study

The study is delimited specifically to working capital management and profitability. Other factors that may influence SME performance, such as entrepreneurial orientation, leadership style, marketing strategy, capital structure, taxation, technology and human-resource management, are outside the principal focus of the study.

The study is also delimited to selected SMEs rather than large corporations. This is because the financial characteristics, financing constraints and working capital requirements of SMEs may differ from those of larger corporations.

The geographical delimitation to Onitsha Metropolis is intended to provide a manageable and context-specific investigation of working capital practices among businesses operating in an important commercial centre in Anambra State.
