Although the use of the Point-of-Sale (POS) systems, computerized inventory management, electronic payments, and digital communication tools started in 2020, the long queues, stockouts, and inaccurate data remained some of the concerns, whether these technologies could have provided the desired speed, accuracy, and cost-effectiveness. The study embraced a descriptive cross-sectional case study design. A census-based sample of 30 out of 32 staff (management, cashiers, and inventory personnel) provided primary data collected using structured Likert-scale questionnaires and interviews. Thematic analysis, Pearson correlation, and descriptive statistics (means and standard deviations) were used to analyse the data. The results showed the significant positive effect of digital technologies on operational efficiency (the overall mean = 3.85). The strongest influence on accuracy and reliability was on POS systems (mean = 3.90; r = 0.78) and then inventory systems on real time tracking (mean = 3.89; r = 0.72). The intermediate impact was on the speed of service using digital communication tools (mean = 3.63; r = 0.58). Nevertheless, infrastructural obstacles (network and power instability), technical hiccups, and lack of staff digital skills were significant hindrances to full benefits. The research concludes that digital technologies have significantly improved the working efficiency of Paris Corner Supermarket, but the most significant benefits can be achieved with the additional investments into the effective infrastructure and constant training. The suggestions are two-WAN internet backup, digital skills training (once a month), and cycle counting. The results will have practical implications to medium sized supermarkets, as well as, policy implications in terms of the digital transformation of the Uganda retail industry.
