We hold inventory. You pull on demand. Capital efficient.
Vendor-Managed Inventory (VMI) services. We hold buffer inventory of your parts, ship per your demand pull. Reduces your inventory carrying cost, eliminates production lead time at order, simplifies procurement to scheduled releases.
Vendor managed inventory
Different VMI structures suit different customer needs. We support various models from simple buffer stock to integrated demand planning.
VMI program structures.
Buffer stock
We hold inventory in customer-paid forward position. Inventory invoiced when produced, held until shipped. Standard pricing model.
Consigned inventory
We retain inventory ownership, invoice on shipment to customer. No customer capital tied up. Typically 5-10% premium over standard pricing.
Min/Max replenishment
Customer sets min/max inventory levels. We automatically replenish when inventory drops to min, holding to max. Customer doesn't need to issue individual POs.
Kanban pull
Customer Kanban signal triggers replenishment. Common for production lines with steady demand. We track Kanban signals and resupply.
Forecasted production
Customer provides production forecast. We build to forecast, hold inventory, ship per actual orders. Smooths our production while serving customer needs.
JIT (Just-in-time)
Daily or weekly scheduled deliveries to customer's production line. We hold inventory, deliver per schedule. Customer minimizes inventory at their location.
Sequential delivery
Parts delivered in production-line sequence. Common for automotive Tier-1 supply. Each delivery includes parts in sequence used at customer's line.
Web portal access
Customer accesses inventory dashboard online. See current stock, recent shipments, forecast vs actual. Procurement transparency.
Periodic invoicing
Single monthly invoice for all VMI shipments. Simplifies AP processing vs individual PO/invoice cycles.
Different VMI structures suit different customer needs. We support various models from simple buffer stock to integrated demand planning.

We hold inventory — questions
How much inventory should we hold?
Typical buffer: 2-3 months of demand for steady-state programs. For demand variability, more buffer. For seasonal patterns, build pre-season inventory. Specific amount calculated per: average demand, demand variability, lead time to replenish, customer service level target. We work with customer on optimal inventory model — too much costs money, too little risks stockouts.
Who pays for inventory holding?
Two models: (1) Customer-paid: customer pays for parts when produced, holding charge for storage. Lower per-unit cost, customer carries inventory cost. (2) Consigned: we retain ownership, invoice on shipment. Customer pays only when used. Higher per-unit cost, customer no inventory cost. Choose based on capital efficiency vs price preference.
What if customer demand changes?
For demand reduction: built inventory must be consumed eventually. We work with customer on consumption plan. For severe reduction (program cancellation), inventory may need to be scrapped — cost shared per agreement. For demand increase: we ramp production. Buffer accommodates short-term spikes; sustained increase requires capacity expansion. Standard escape clauses in VMI agreements.
Quality of stocked inventory?
Same quality as standard production. Inventory regularly cycled — FIFO (first in first out) ensures no aging issues for most metals. For materials with shelf-life concerns (some adhesives, specific plastics), inventory dating tracked, expired material disposed properly. Customer receives fresh stock per pull.
Geographic flexibility?
Inventory typically held at our Wuxi facility. For customers needing local stock (US, EU, Asia), we can establish local stocking through partner warehouses. Trade-off: faster delivery vs additional cost. For high-volume programs justifying local stock, customer-specific arrangement possible.
When does VMI make sense?
VMI valuable when: (1) Steady ongoing demand (not one-off projects). (2) Customer has working capital constraints. (3) Quick response time matters. (4) Production line with predictable consumption. (5) Multiple part numbers to coordinate. For one-time projects or highly variable demand, traditional PO model often adequate. For sustained production, VMI typically saves cost and improves service.
