In today’s increasingly complex and volatile supply chain landscape, collaboration is more than a buzzword—it’s a competitive advantage. One of the most effective collaborative practices that fosters both operational efficiency and deeper trust across trading partners is Vendor-Managed Inventory (VMI).
What Is VMI?
At its core, Vendor-Managed Inventory is a supply chain strategy where the supplier takes responsibility for managing and replenishing the customer’s inventory. Instead of the customer issuing a purchase order, the vendor monitors stock levels—often through shared digital access—and ensures the right quantity is available at the right time.
Sometimes referred to as continuous replenishment, this approach shifts the dynamic from a transactional relationship to a strategic partnership, where both parties work together to streamline inventory, reduce stockouts, and avoid overstocking.
Why VMI Works: Key Benefits
Implementing VMI creates value on several levels—for both suppliers and customers:
1. Increased Trust and Visibility
VMI thrives on data sharing and transparency. When a customer opens their inventory data to a supplier, it’s a clear sign of trust. In return, suppliers gain real-time insight into product movement, demand variability, and replenishment needs, enabling more proactive service.
2. Lower Inventory Costs
With suppliers better able to predict needs, safety stocks can be optimized, obsolescence reduced, and holding costs minimized. Many companies report a 20–30% reduction in inventory levels when VMI is implemented properly.
3. Improved Service Levels
Fewer stockouts and better shelf availability directly impact customer satisfaction and sales. VMI helps ensure that the right products are on hand when needed—without waiting for a manual order to be placed.
4. Operational Simplicity
Customers no longer need to forecast, order, or schedule as frequently. Suppliers become fully accountable for ensuring product availability within agreed-upon parameters.
5. Environmental & Sustainability Gains
Less emergency shipping, better batch planning, and fewer returns or wasted products lead to a more sustainable supply chain. These environmental metrics—such as reduced emissions and waste—are increasingly important to stakeholders.
Where VMI Fits in the SCOR Model
The SCOR DS framework explicitly links VMI with process categories like Plan Source, Plan Fulfill, and Fulfill B2B, and aligns with metrics such as:
- RL.1.2 – Perfect Supplier Order Fulfillment
- EV.1.4 – GHG Emissions
- EV.2.10 – Generated Waste Diverted from Disposal
VMI is also linked to critical practices in Supplier Relationship Management (SRM), Warehouse Management, and Blanket Purchase Orders.
Verified European Examples of VMI
1. Heineken Netherlands
Heineken implemented a VMI collaboration with a major Dutch customer, involving five distribution centers and 36 product types. The initiative led to a 15% increase in transport utilization compared to non-VMI deliveries. Additionally, simulations indicated potential reductions in customer inventory levels by up to 70%, highlighting significant efficiency gains.Eindhoven Tech Research Portal+1ESCF+1ESCF+1Eindhoven Tech Research Portal+1

2. Bosch Europe
Bosch utilizes VMI across its European operations, particularly in its Charleston plant, which manages over 2,000 production parts with 175 suppliers. Through the SupplyOn platform, suppliers access daily inventory data to determine shipment quantities, ensuring timely replenishment and minimizing stock discrepancies.SupplyOn+1SupplyOn+1SupplyOn+3SupplyOn+3SupplyOn+3

3. Carrefour France
Carrefour, one of Europe’s largest retailers, adopted VMI practices in the late 1990s to enhance collaboration with suppliers. This approach allowed suppliers to manage inventory levels directly, leading to improved stock availability and reduced inventory holding costs for Carrefour.

Is VMI Right for You?
While VMI isn’t a one-size-fits-all solution, companies operating in stable, high-volume environments with trusted partners stand to gain significantly. It requires investment in data sharing, process alignment, and a mutual commitment to shared success.
But when done right, VMI is more than an inventory tactic—it’s a relationship and performance enabler that drives business results.
Final Thoughts
In an era where collaboration is key to resilience, Vendor-Managed Inventory represents one of the most practical and proven ways to build that collaboration. It’s not just about reducing costs or improving fill rates—it’s about building a supply chain culture of trust, transparency, and mutual performance.
