In the face of heightened global competition, micro and small enterprises (MSEs) in Durban, South Africa, face challenges such as limited resources and restricted market access, which hinder their ability to achieve sustained growth and profitability. This study aims to examine the influence of the 4Ps marketing mix on the performance of MSEs. A cross-sectional, descriptive study with a quantitative research design was employed. Data was collected from 217 MSEs using structured questionnaires, and the analysis was conducted with SPSS 29. Multiple regression analysis was used to examine the relationship between the 4Ps (product, price, promotion, place) and MSEs' performance. The findings show that pricing decisions are a significant determinant of performance, while product diversity does not necessarily enhance business outcomes, emphasizing the importance of strategic product management. Promotional efforts, while positive, were statistically insignificant, indicating complexities in their impact. The relationship between physical location (place) and performance was weak, suggesting a need for MSEs to optimise distribution channels through omnichannel strategies. In conclusion, MSEs can improve performance by refining promotional strategies, leveraging pricing and optimising distribution networks. Further research is suggested to explore the generalizability of these findings across different industries and additional factors influencing marketing strategies.
