Vendor-Managed Inventory: How Suppliers Manage Your Stock and You Pay Only on Sale

How vendor-managed inventory works#

You and supplier agree on a VMI arrangement for a product category. The supplier ships inventory to your warehouse and retains ownership. Your inventory system tracks unit sales in real-time. At the end of each week, you pay the supplier only for units that were sold that week (at the agreed unit price). Unsold inventory remains the supplier's property. The supplier monitors your inventory level and restocking frequency through data feeds and decides when to resupply. When inventory drops below an agreed threshold, the supplier automatically ships a replenishment order. You receive inventory continuously but only pay for what you actually sold.

Benefits of VMI for the buyer#

Working capital freed: you don't pay for inventory until you sell it, freeing 30-50% of the working capital normally tied up in inventory. Stockout risk eliminated: the supplier owns the risk of excess inventory and is incentivized to maintain appropriate stock. Forecasting simplified: you don't need to forecast and place orders — the supplier uses POS data to anticipate replenishment needs. Cash flow improved: you collect revenue from customers before paying the supplier, creating positive working capital cycle.

Benefits of VMI for the supplier#

Demand visibility: real-time sales data tells the supplier exactly what is selling, enabling better demand forecasting and production planning. Inventory optimization: with visibility to your sales the supplier can reduce their safety stock and improve inventory turns. Customer intimacy: VMI creates a deeper partnership and reduces the risk of being de-listed or losing volume. Pricing stability: with better forecasting the supplier can lock in better raw material prices and pass value back to the customer.

VMI arrangement structure and governance#

Establish: minimum and maximum inventory levels (the supplier maintains stock within this range), automatic replenishment triggers (when you hit minimum, supplier ships), payment terms (typically pay weekly for units sold), inventory ownership (supplier owns unsold stock), data sharing (you provide daily or weekly POS data), and performance metrics (stockout frequency, inventory accuracy, order fulfillment rate).

AskBiz VMI Manager#

AskBiz identifies product categories suitable for VMI (high-volume, fast-moving, stable demand). It tracks inventory levels and sales by product, calculates the working capital freed by VMI vs traditional ordering, and manages data feeds to VMI suppliers. It tracks inventory accuracy and stockout frequency as VMI performance metrics. Ask it: which products should I move to VMI with this supplier, how much working capital would I free with VMI on my top 10 products, show me the stockout frequency and inventory health of my VMI relationships.

• Vendor-managed inventory (VMI) is an arrangement where your supplier owns the inventory in your warehouse until you sell it.
• You pay only for units sold.
• The supplier manages restocking, reducing your working capital by 30-50% and eliminating stockout risk.
