Flex-Stock · Vendor Managed Inventory
We hold your packaging stock and ship per call-off, on your production schedule.
Flex-Stock is JMP's vendor-managed inventory (VMI) program for automotive suppliers: we make your packaging in advance, hold it as a buffer in our warehouse, and deliver exactly when your line needs it.
In short: we hold the stock
Vendor managed inventory (VMI) is a scheme where the supplier — not you — manages your stock: producing ahead, holding a buffer, and replenishing as you use it. For packaging, that means we produce and hold your carton box and polybag stock in advance, then ship it per call-off exactly when your line needs it — so you're not tying up floor space on bulk stock, and you're not stopping the line because packaging arrived late. JMP's packaging VMI program is called Flex-Stock.

How Flex-Stock works
Four steps. Packaging stock becomes our job; your line never waits.
- 1 Produce ahead
- 2 Buffer stock in JMP warehouse
- 3 Call-off on schedule
- 4 Your production line
Why automotive suppliers use packaging VMI
Your floor stays clear
The packaging buffer sits in our warehouse, not on your production floor. You pull what you need.
The line keeps running
Packaging is ready before you need it. No line waiting on late cartons or polybags.
One vendor, two packagings
Carton box and polybag under one QC standard and one delivery schedule — not two suppliers pointing fingers.
What does holding your own packaging stock cost?
Holding packaging stock rarely reads as a cost — no invoice arrives for it each month. The warehouse space and the cash sitting in a stack of cartons are paid for all the same. Enter your own numbers below; everything is calculated in your browser and nothing is sent anywhere.
