Small and Medium-sized Enterprises (SMEs) are more adaptable because of their size and straightforward structure; they will be better able to take advantage of changes and innovation. SMEs are common in the nation and have significantly increased Pakistan’s GDP. To achieve and guarantee these SMEs’ effective performance, they must improve the quality of their services. For this reason, the current study has looked into the significance of Supply Chain Integration (SCI). The present research has adopted a “quantitative research design” to conduct the study. Concerning the research framework, the independent variable is supplying chain logistic issues that impact SME service quality through the mediation of supply chain integration. There are two methods adopted for the data analysis. Firstly, the statistical package for social sciences (SPSS) is employed for the demographic outcomes. Secondly, regression, reliability and validity analysis are carried through the Structural Equation Model (SEM). The results of the study indicated the six linkages. Firstly, the association of High Cost of Information Technology (HCI) positively impacts Coordination and collaboration. Secondly, Quality Logistic Personnel (QLP) is positively and significantly associated with Commitment and competence. Thirdly, HCI indicated a positive link with Coordination and collaboration. Fourthly, QLP expresses a positive and significant relationship with Coordination and collaboration. Fifthly, QLP demonstrated a positive and significant association with Creativeness and customisation. Finally, QLP showed insignificant negative results with Coordination and collaboration. The present study holds greater significance in this regard. The study provides valuable insights to the employees or workforce of SME businesses to supervise or rationally monitor their supply chain performance. The service quality of SMEs has been measured through commitment and competence, creativity and customization, and coordination & collaboration of sales logistic personnel.
