EFFECT OF INTERNAL CONTROL SYSTEMS ON THE FINANCIAL PERFORMANCE OF SELECTED SMALL AND MEDIUM-SIZED ENTERPRISES IN NASARAWA TOWN, NASARAWA STATE, NIGERIA

CHAPTER ONE: INTRODUCTION

1.1 Background to the Study

Small and medium-sized enterprises (SMEs) play an important role in economic development through employment creation, income generation, entrepreneurship and the provision of goods and services. In Nigeria, these businesses operate in several sectors, including trading, manufacturing, agriculture, transportation, hospitality, information and communication technology, and professional services. They provide opportunities for individuals to establish businesses, develop practical skills and contribute to the economic activities of their communities.

The contribution of SMEs to Nigeria's economy makes their financial performance an important subject of study. PwC Nigeria (2024), drawing on the national Micro, Small and Medium Enterprises (MSME) survey conducted in 2021, reported that MSMEs accounted for approximately 96.9% of businesses in Nigeria and 87.9% of employment. Although these figures relate to MSMEs, which include microenterprises, they illustrate the importance of smaller businesses to the country's economic structure. Their contribution also highlights the need to understand the factors that support their financial stability and long-term survival.

Despite their importance, SMEs often operate in challenging business environments characterised by limited capital, changing customer demand, rising operating expenses, competition and difficulties in obtaining affordable financing. These challenges can become more serious when business owners lack reliable financial records or do not have effective procedures for controlling cash, inventory, expenditure and credit transactions. A business may record considerable sales but still struggle to pay its suppliers or employees if expenses are poorly managed, customers fail to settle their debts or business funds are used without proper documentation. Consequently, generating revenue alone does not guarantee strong financial performance.

One management mechanism that can help address these challenges is an effective internal control system. Internal control systems comprise the policies, procedures, organisational arrangements and routine practices established by management to safeguard business assets, improve the reliability of financial information, manage risks and support the achievement of business objectives. The Committee of Sponsoring Organizations of the Treadway Commission (COSO, 2013) identifies five interconnected components of internal control: control environment, risk assessment, control activities, information and communication, and monitoring. These components provide a framework for understanding how businesses can organise their financial and operational activities to reduce avoidable losses and improve accountability.

The control environment establishes the foundation for effective internal control. It concerns management's commitment to ethical conduct, accountability, competence and the consistent application of business procedures. In an SME, the owner's attitude towards financial discipline can strongly influence how employees handle transactions and business resources. For instance, when a business owner insists on issuing receipts, recording daily sales and documenting expenses, employees are more likely to follow established procedures. Conversely, where financial rules are ignored or applied inconsistently, the risk of errors, unauthorised spending and unreliable financial records may increase.

Risk assessment is another important component because SMEs face financial and operational threats that may affect their performance. These include theft, fraud, bad debts, inventory losses, cash shortages, cyber-related risks and unexpected increases in operating costs. Risk assessment involves identifying possible threats, evaluating their consequences and establishing appropriate responses. For example, a business that sells goods on credit may introduce credit limits and regularly review outstanding customer balances. Similarly, an enterprise that receives electronic payments may review transaction notifications and reconcile its bank statements with its sales records.

Control activities are the practical procedures used to manage identified risks. They include transaction authorisation, segregation of duties, proper documentation, physical protection of assets, inventory verification and regular reconciliation. COSO (2013) emphasises that control activities work as part of an integrated system rather than as isolated administrative requirements. Although SMEs may lack the workforce needed to assign every financial task to a different employee, they can introduce proportionate controls. An owner-manager, for instance, may personally review bank statements, compare stock records with physical inventory and examine supporting documents before approving significant payments.

Information and communication are equally important because financial decisions depend on accurate and timely information. SMEs that maintain reliable records of sales, purchases, operating expenses, customer debts and inventory are better positioned to assess their financial position. In contrast, incomplete records and delayed reporting can make it difficult to determine whether a business is profitable, whether expenses are increasing excessively or whether sufficient cash is available to meet short-term obligations.

Monitoring involves reviewing internal control procedures to determine whether they are operating effectively and whether improvements are needed. As a business expands, employs more workers or adopts new payment technologies, existing procedures may no longer be adequate. Regular reviews of cash records, bank balances, stock levels, expenses and outstanding debts can help management identify weaknesses and take corrective action before financial problems become more serious.

The relevance of internal control to SME performance has been examined in Nigerian empirical research. Oyelakin and Abdullahi (2022) investigated employee training and internal control in relation to financial management among SMEs in Abuja. Their findings indicated that employee training, the control environment, information and communication, and risk assessment had significant positive effects on financial management, while the results for control activities and monitoring differed from the expected positive pattern. This suggests that the contribution of individual internal control components may vary and should be examined rather than assumed.

Similarly, Ajala et al. (2023) investigated internal control systems and organisational performance among SMEs in Ondo State. Their findings indicated positive relationships between internal control systems and business growth, business survival and operational efficiency. Although these outcomes are relevant to business performance, they are not identical to direct financial measures such as profitability, liquidity and sales growth.

Igbojioyibo (2024) also examined internal control in relation to asset protection and financial reporting accuracy among SME owners in Nigeria. The reported findings highlighted relationships between internal control systems, asset protection and the accuracy of financial reporting. These outcomes suggest that internal control may support financial performance by protecting business resources and improving the information used in management decisions. However, stronger controls do not automatically guarantee higher profits because business results may also depend on customer demand, competition, financing costs and general economic conditions.

In Nasarawa Town, SMEs operate within a local business environment that includes retail trading, foodstuff distribution, agricultural produce marketing, small-scale manufacturing, personal services and other commercial activities. Businesses in these sectors may handle daily cash receipts, customer credit, inventory purchases, transportation expenses and payments to suppliers. Effective control procedures can help owners understand how money enters and leaves their businesses, identify losses and make informed decisions about pricing, purchasing and expansion.

Nevertheless, the nature and quality of internal controls may differ from one enterprise to another. Some businesses may use formal accounting systems, while others may depend on handwritten records, basic spreadsheets or the owner's personal supervision. In smaller enterprises, the same person may receive money, record transactions, purchase inventory and approve payments. Such arrangements may be understandable given limited staffing and financial resources, but they can also make independent verification difficult.

This creates a need to investigate whether the internal control practices adopted by selected SMEs in Nasarawa Town are associated with measurable financial outcomes. The present study will examine the control environment, risk assessment, control activities, information and communication, and monitoring in relation to profitability, sales growth, liquidity and cost control. By focusing on selected enterprises in a defined location, the study will seek to provide practical evidence on how internal control systems relate to the financial performance of SMEs and identify areas where improvements may be beneficial.

1.2 Statement of the Problem

SMEs contribute to employment, income generation and commercial activities in Nigeria, yet their financial performance can be affected by weaknesses in financial management and internal control. Difficulties such as cash shortages, inaccurate records, inventory losses, unpaid customer debts and uncontrolled operating expenses can place pressure on business resources. Where these problems persist, an enterprise may find it difficult to meet its financial obligations, maintain profitability or expand its operations.

One possible factor associated with these difficulties is the inadequacy of internal control systems. Some SMEs may operate without clearly documented financial procedures, regular stock verification, systematic cash reconciliation or consistent authorisation of expenditure. Others may depend heavily on the owner or a single employee to manage several financial responsibilities. Where independent checks and reliable documentation are limited, mistakes or irregularities may remain undetected, making it difficult for management to determine the actual financial position of the business.

However, the existence of internal control procedures does not necessarily mean that they are effective. A business may keep records but fail to review them regularly. Another may establish expenditure approval procedures but allow exceptions without adequate justification. Some enterprises may also find formal accounting systems too expensive or complicated to implement. It is therefore important to examine the effectiveness of the controls actually practised rather than merely establish whether a business claims to have internal control procedures.

Previous Nigerian studies offer useful evidence, but they also indicate the need for further investigation. Oyelakin and Abdullahi (2022) found that the effects of internal control components on financial management differed across components among SMEs in Abuja. Ajala et al. (2023) reported positive relationships between internal control and organisational performance among SMEs in Ondo State. While these findings provide a foundation for the present study, financial management and organisational performance are not interchangeable with financial performance measured directly through profitability, liquidity, sales growth and cost control.

Furthermore, findings obtained from SMEs in Abuja or Ondo State may not fully represent the circumstances of enterprises operating in Nasarawa Town. Differences in business activities, management practices, access to finance and local market conditions may influence the way internal controls are implemented and the outcomes they produce. A location-specific investigation is therefore useful for understanding the practices of the enterprises included in the study.

The problem this study seeks to address is the need for empirical evidence on the effect of internal control systems on the financial performance of selected SMEs in Nasarawa Town, Nasarawa State. Specifically, the study will examine the individual contributions of the control environment, risk assessment, control activities, information and communication, and monitoring, as well as the combined relationship between these components and financial performance.

The findings are expected to help business owners and managers identify practical ways to strengthen financial accountability, safeguard assets and improve the quality of financial decisions. The study will also contribute to the Nigerian SME literature by examining internal control systems in relation to clearly specified financial performance indicators within a defined geographical area.

1.6 Significance of the Study

The findings of this study are expected to benefit SME owners and managers, employees, government agencies, financial institutions, accounting professionals, researchers and students.

1.6.1 SME Owners and Managers

The study may help SME owners understand the importance of maintaining effective financial control procedures. The findings could guide them in adopting practical measures such as daily cash reconciliation, expenditure authorisation, inventory checks, proper documentation and regular reviews of financial records. These practices may help them identify avoidable losses and make better-informed business decisions.

1.6.2 Employees of SMEs

The study may improve employees' understanding of their responsibilities in protecting business assets, recording transactions accurately and complying with established procedures. Clear responsibilities and appropriate supervision may reduce mistakes and promote accountability.

1.6.3 Government and SME Development Agencies

The findings may provide information for agencies responsible for entrepreneurship development, SME training and business support. The results could help inform programmes that encourage business owners to adopt affordable accounting and internal control practices.

1.6.4 Financial Institutions and Investors

The study may be useful to banks, microfinance institutions and other business financiers seeking to understand the financial management practices of SMEs. Reliable records and effective controls can support the assessment of a business's financial position, although they do not independently determine whether a business qualifies for financing.

1.6.5 Accounting Professionals and Business Consultants

Accountants, auditors and business advisers may use the findings to identify common control weaknesses and recommend procedures suited to the size and resources of individual enterprises. This may encourage the adoption of proportionate controls that protect assets without imposing unnecessary administrative costs.

1.6.6 Researchers and Students

The study will contribute to academic discussions on internal control systems and SME financial performance in Nigeria. It may also provide a foundation for further research in accounting, finance, business administration and entrepreneurship.

1.7 Scope of the Study

The study will focus on the effect of internal control systems on the financial performance of selected SMEs in Nasarawa Town, Nasarawa State, Nigeria.

Content scope: The independent variable is internal control systems, measured through five components: control environment, risk assessment, control activities, information and communication, and monitoring. The dependent variable is financial performance, assessed using profitability, sales growth, liquidity and cost control.

Geographical scope: The research will cover selected SMEs operating in Nasarawa Town. The specific businesses will be identified through an appropriate sampling procedure.

Population scope: The target respondents will include SME owners, managers, accountants, bookkeepers and other personnel who have sufficient knowledge of the financial procedures and performance of their respective businesses.

Time scope: The researcher should specify the period covered by the investigation. Where records are available, the study may examine financial performance and internal control practices over the preceding three financial years. The final period should be determined by data availability and the institution's requirements.

The study will be limited to the selected enterprises and will not automatically represent every SME in Nasarawa State or Nigeria.

1.8 Limitations of the Study

The study may encounter several limitations.

First, some SMEs may not maintain complete financial records, making it difficult to obtain reliable figures on profits, sales and liquidity. Second, some respondents may be reluctant to disclose financial information because they consider it confidential. Third, questionnaire responses may reflect personal opinions rather than objectively verified business results.

Differences in business size, sector, ownership structure and market conditions may also affect financial performance independently of internal control systems. In addition, a cross-sectional study may identify statistical relationships without conclusively establishing causation.

To address these challenges, the researcher will assure respondents that their information will be treated confidentially, use clear research questions and, where permission is granted, compare responses with available accounting records. The researcher will also apply consistent measurement procedures and consider relevant business characteristics during data analysis where the available data permit.

1.9 Operational Definition of Terms
