Most production units can produce an inventory valuation report. Far fewer can answer the harder question: what did that specific batch cost to make, including wastage?
Standard versus actual consumption
Once a recipe exists, the system can compare what should have been consumed against what was issued. The gap is where money disappears.
Wastage and yield are commercial signals
A rise in wastage percentage on one line is usually a machine, material or training issue — and it is invisible if you only look at total stock value.
Pricing without batch costing is guesswork
If you cannot see batch cost, price revisions are based on averages that hide your worst-performing product.
