Game-changer for our Supply Chain Performance **Rating:** 5.0/5.0 stars **Reviewed by:** Ehsan G. | Small-Business (50 or fewer emp.) **Reviewed Date:** July 07, 2023 **What do you like best about Slim4?** The power of Slimstock lies in its advanced forecasting algorithms, with which we can now accurately predict customer demand, allowing us to optimize inventory levels and minimize the risk of stockouts. This has not only improved our order fulfilment rates but also enhanced customer satisfaction as we meet their expectations at a much higher rate than previously. Slimstock has been a catalyst for our supply chain transformation at Parfym.se. Its powerful features and capabilities have empowered us to achieve optimal efficiency, reduce costs, and enhance customer satisfaction. **What do you dislike about Slim4?** Nothing really that didn´t meet our requirements. **What problems is Slim4 solving and how is that benefiting you?** At Parfym.se, we have experienced firsthand the remarkable impact of Slimstock. Taking the leap away from our many legacy systems and manual processes, Slimstock has transformed our operations and propelled us towards supply chain excellence. Due to increased business complexity and profitability requirements, keeping our legacy systems was no longer an option. We looked for a supply planning platform with a comprehensive suite of advanced planning and optimization features to modernize our inventory management and demand forecasting approach. Slimstock's inventory optimization capabilities have been a game-changer for us as we distribute over 15.000+ SKUs from 70+ suppliers. By considering various factors such as lead times, supplier performance, promotions, and seasonal fluctuations, we can now determine the optimal inventory levels for each product. This has enabled us to reduce our carrying costs while gradually increasing our service levels. Slimstock's automated replenishment tools and exception management have revolutionized our processes, enabling us to generate accurate and optimized purchase orders (via EOQs, order fill functionalities, etc.). This has eliminated excess inventory and reduced stockouts, allowing us to operate with optimal efficiency. ### 2.
