To support its rapid growth and complex product portfolio, Alliance Automotive Group, a leading supplier in the European automotive aftermarket, launched a supply chain transformation initiative. Powered by Slim4, the company has improved product availability and reduced excess stock, laying the foundation for future expansion.
Alliance Automotive Group, a leading European automotive aftermarket player, supplies parts for cars and commercial vehicles in France. Focusing on both organic and external growth, Alliance Automotive Group has extended its footprint to cover over half of the European independent aftermarket.
Supplying mechanical parts, bodywork components, and a wide range of related products, Alliance Automotive provides the network with a complex product portfolio, offering its customers tailored solutions for their business. With a fast-growing business that is constantly evolving to meet the needs of its stakeholders, be they repairers, affiliated distributors, or suppliers, Alliance Automotive requires an innovative and scalable solution to support further development.
The challenge
Maintaining the right stock in the right place at the right time is a familiar challenge for procurement teams. For Alliance Automotive, however, this task was becoming increasingly difficult to manage at scale.
Thomas Doublet, Head of Procurement at Alliance Automotive, explains: “Before Slimstock, we like to say we managed stock like craftsmen. That meant we had deep product knowledge and strong intuition, but it was time-consuming and not always efficient. As our operations expanded, we needed more robust planning capabilities.”
To increase product availability while reducing excess stock and improving working capital, the company launched a supply chain transformation project. With this initiative, Alliance Automotive aimed to balance thousands of SKUs and multiple locations, transforming planning performance at its core.
Results
Slim4 offered a robust, data-driven planning solution to replace manual processes with strong supply planning algorithms. From demand forecasting to order management, Slim4 provided the transparency and control the team needed to manage inventory effectively across the entire network.
“We’ve embraced a much more structured way of working,” Thomas says. “The system supports better decision-making through improved forecasting, smarter replenishment, or stronger alignment between teams.”
Since implementing Slim4, Alliance Automotive has seen outstanding results:
- A 10-point increase in product availability.
- €1 million reduction in stock value.
“We have seen significant improvements since the rollout. With a few indicators, notably stock value and product holdings, we can see that we’ve increased our holdings by 10 points in two years and reduced our stock value by about a million euros,” Thomas highlighted.
Looking ahead
As Alliance Automotive continues to scale, Slim4 will play a central role in supporting further improvements across the business. Thomas concludes: “Within the Group, we have already deployed the tool across five platforms. In the medium term, we aim to extend it to all six of our regional platforms that are not yet using it. We are confident that, with Slimstock’s support, we will meet our growth goals in the long run.”
