Inventory Cost | Optiwise
Understand inventory cost in manufacturing, including purchase cost, carrying cost, shortage cost, ordering cost, obsolete stock, and working capital impact.
Inventory Cost
Inventory cost is more than the price paid to buy material. In manufacturing, inventory cost includes the money spent to acquire stock, the cost of holding it, the cost of running out of it, and the cost of dealing with material that becomes slow, damaged, obsolete, or difficult to use.
This is why two manufacturers with the same sales can have very different cash flow. One may carry lean, useful stock. Another may carry too much old material while still facing shortages for critical items.
AICAN Optiwise helps manufacturers see inventory cost more clearly by connecting stock with purchase, production, ageing, and planning data.

What Is Inventory Cost?
Inventory cost refers to the total cost associated with purchasing, holding, managing, and using inventory.
It may include:
- Purchase cost
- Freight or landing cost
- Ordering cost
- Carrying cost
- Storage cost
- Handling cost
- Insurance
- Damage and shrinkage
- Obsolescence
- Shortage cost
- Working capital cost
The visible invoice price is only one part.
Purchase Cost
Purchase cost is the cost paid to suppliers for raw material, components, consumables, or finished goods. It may include additional costs depending on accounting treatment.
Manufacturers should track purchase cost by item, supplier, and period. Rate changes affect product costing and quotation accuracy.
Ordering Cost
Ordering cost includes the effort and expense of placing and managing purchase orders.
It may include:
- Purchase team time
- Supplier follow-up
- Documentation
- Transport coordination
- Inspection effort
- Payment processing
Too many small orders can increase administrative cost. Too few large orders can increase carrying cost.
Carrying Cost
Carrying cost is the cost of holding inventory. This is often underestimated.
It includes:
- Warehouse space
- Handling
- Damage
- Insurance
- Obsolescence
- Capital tied up in stock
- Counting and control effort
A material that sits unused for months is not free just because it is already paid for.
Shortage Cost
Shortage cost occurs when required stock is not available.
It may include:
- Production stoppage
- Overtime
- Emergency purchase
- Expedited freight
- Late dispatch
- Customer dissatisfaction
- Lost sales
Shortage cost explains why the lowest inventory level is not always the best level.
Obsolete And Slow-Moving Cost
Old stock can lose value. It may become unusable due to design change, shelf life, customer cancellation, corrosion, damage, or product discontinuation.
Review slow-moving and obsolete stock regularly to avoid hidden losses.
Balance Cost And Availability
Good inventory cost management balances holding cost and shortage risk. The goal is not lowest stock. The goal is right stock.
Use:
- ABC analysis
- Reorder levels
- Safety stock
- Aging review
- Supplier lead time tracking
- Demand forecasting
- Cycle counting
How Optiwise Helps
Optiwise by AICAN helps manufacturers track stock value, movement, ageing, purchase history, and shortages. This gives owners better visibility into where inventory cost is helping production and where it is blocking cash.
Better visibility leads to better stock decisions.
Founder’s Note
At AICAN, we believe inventory cost should be understood by both finance and operations. Stores may see material. Finance may see value. Owners need to see the business impact.
Optiwise helps connect those views.
FAQs

It shows the hidden cost of keeping stock, including space, capital, handling, and risk of obsolescence.
Can too little inventory increase cost?
Yes. Stockouts can cause production stoppage, emergency buying, late delivery, and lost sales.

AICAN Optiwise helps track stock movement, ageing, purchase history, and shortages so manufacturers can reduce excess and avoid stockouts.
