As the world’s leading manufacturer of lead-acid batteries, Yuasa’s broad assortment encompasses everything from high performance automotive and motorcycle batteries to reliable industrial and leisure power products. From their manufacturing facilities located in the UK and the Far East, Yuasa supply an international network of distributors with the widest variety of products available in the market. As the complexity of their operation continued to grow, Yuasa turned to Slimstock to help better align their assortment with the ever changing demands of the market.

Given that many of the items within Yuasa’s assortment are subject to complex seasonal patterns, product life cycles and extensive lead times of up to 4 months, keeping the inventory under control can often prove an extremely challenging undertaking for Kevin Morris and his team. “The end consumer will simply not wait if the item they require is out of stock; therefore, ensuring our distribution partners are able to offer consistently high levels of availability is of paramount importance,” explains Kevin Morris, Inventory and Logistics Manager at Yuasa Battery Sales (UK) Ltd. As the time and effort required to manage the inventory grew, Yuasa required a solution which could not only streamline their inventory management processes but could also optimise the assortment in order to ensure the right products are available for purchase.

“Prior to implementing Slim4, we relied on spreadsheets to manage the inventory. While this provided an overview of the inventory situation, reviewing the data in this way could often prove a cumbersome undertaking. As a consequence, we simply did not have time to analyse the data effectively.” With Slim4, Yuasa are now able to monitor the performance of their inventory far more closely. “We now review forecast accuracy on a daily basis, which in turn allows us to proactively manage exceptions before they can have an impact,” explains Kevin.


It was also key that the team at Ideal Bathrooms had the means to monitor supplier performance and take action where required. With the order book functionality within Slim4, they can now easily track delayed and missed orders and respond accordingly. Nick explains “We already have in place structured supplier performance improvement programmes. However, through combining these insights from Slim4 with the metrics collected from other sources, we will further improve the way we work with suppliers.”

Although Slim4 has only been in place for a few months, Nick has big ambitions for the future: “Now that we are confident with Slim4, we want to improve our operations further by increasing the level of automation as well as continuing to refine our processes.” Nick goes on to conclude: “From start to finish, the implementation of Slim4 has been a huge success and I have no doubt that Slim4 will play a crucial role in helping us to keep up with our rapid year on year growth.”

“The advantage of this was particularly evident in the run up to winter, our busiest period, where we achieved availability in excess of 99.9% across our A-line items while simultaneously reducing the need to make urgent orders.”
