Abstract:
Purpose: Small Medium Enterprises (SMEs) play an essential role in the sustainable 
development of developed or developing countries to achieve inclusive economic 
growth. The World bank recommended this sector for the fast recovery from 30 years of 
internal conflict in the Sri Lankan economy. These SMEs face severe challenges due to a 
lack of knowledge in working capital management approaches. The purpose of this 
study is to examine the impact of working capital management approaches (WCMA) on 
the business performance (BP) of SMEs in the context of a developing economy, Sri 
Lanka. 
Methodology: This study uses a deductive research approach and quantitative 
techniques to assess the working capital management approaches and performance of 
SMEs in Northern Province. To measure WCMA, the study employs cash management, 
receivable payable management, and inventory and business performance were 
measured by sales growth, profit growth, and total asset growth. 410 registered SMEs 
from the population of 24,316 (until 2018) were selected as samples of 33 Divisional 
Secretary by using the proportionate stratified random sampling method and Slovene's 
formula. Primary data was collected through a semi-structured questionnaire. 
Descriptive and inferential analysis methods were done using Excel, SPSS, and SEM 
AMOS. 
Findings: The results reveal a significant positive impact of WCMA on BP. The factors of 
WCMA, cash management (CM), payable receivable management (PRM), and inventory 
management (IM) show the critical ratio (CR or t-value) is greater than 1.96 for an 
estimate (regression weight). In other words, the regression weight for CM, PRM, and IM 
in the prediction of BP is significantly different from zero at the 0.01 level (two-tailed). 
Its statistics show that the WCMA of the SMEs in the NP has a significant influence on BP. 
The study reveals the need for SMEs to ensure efficient WCMA to maximize BP.
Research limitations: This study has covered the limited measurement of WCMA, the 
present state of SMEs in the Northern Province which are registered under the DS office. 
It is better to conduct a survey in the future using data collected from other 
measurement variables and methods and all other provinces of Sri Lanka. Implications: Most of the sample SMEs determined the cash management and 
inventory management based on the owner/manager's experience. Experience is 
viewed as more important than theory in practicing cash management. To strengthen 
their decision, they should follow the proper working capital approaches of managerial 
accounting. Furthermore, the improvement in WCMA leads to an improvement in 
business performance. Hence the owners/managers of SMEs have to increase their 
managerial accounting strategy to monitor and utilize the working capital approaches, 
like management of cash, payable, receivable, and inventory to ensure the most 
financially efficient operation of the business. Accounting skills are necessary for 
successful entrepreneurial and SME development in Sri Lanka. This is because the 
inability to install a proper accounting system would prevent business monitoring, 
reporting, and performance evaluation that are relevant to the business's survival.
