Here is a great contribution from Steve Pappalardo at IMS on how to best manage potential Excess Material:
How do you get the best price and properly manage your excess material?
Companies always drive to the best material cost. In most cases, buying more material than they need to get that great price, assuming they will consume it over time. That may make sense if you have a stable design and schedule.
But what if you’re a startup company or have a new product, what if your design is not stable and you will be making changes? What if you have no idea what the delivery schedule will be? Buying excess material in those instances wastes your cash with no idea when you’ll turn it, if ever.
A mentor of mine used to say, “Stevie, I can’t pay bills with parts.” So true, right? Maybe forfeiting the best possible material price, paying a few percentage points more, and buying exactly what is needed to build the project is a better choice. Keep your cash to spend on things that will benefit your company.
Talk to your contract manufacturer and ensure they have a process to mitigate excess material. If they don’t, find one that does. You never want to try and “pay your bills with parts”!
