INVENTORY ECONOMICS
Inventory Cost
Inventory cost can mean the cost assigned to inventory for accounting or the broader operating costs of acquiring and carrying stock. A useful discussion identifies which meaning, cost categories and period are intended.
INVENTORY COST IN PRACTICE
- Define the measureState valuation, carrying cost or total operating scope.
- Classify the componentsApply the appropriate policy and time basis.
- Reconcile the comparisonRemove overlaps and align assumptions.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
A stock value is not an annual carrying bill.
A company has stock valued at $100,000. A separate planning model applies an illustrative 20% annual holding rate, producing $20,000 per year. These are different measures, not two interchangeable inventory balances.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.
Put this term to work. Use the 3PL pricing and rates guide for the wider invoice context and the guide to comparing 3PL quotes to compare the same scope, activity profile and billing units.
