Katana helps you track manufacturing costs by calculating actual costs for both ingredients and production operations. This ensures visibility into your Cost of Goods Sold (COGS) and profitability.
Where to see manufacturing costs
Once a sales order (SO) is marked as Done, you can view:
Sales Revenue
Cost of Goods Sold (COGS based on the average cost)
Profit per SO
View this in the Done table of the Sell screen.
What makes up manufacturing costs?
Manufacturing costs consist of:
Ingredient costs
These are pulled from the product’s recipe when a manufacturing order (MO) is created.
Cost formula:
Ingredient Cost = Average Cost × Quantity UsedOn Open MOs, costs are based on planned quantities.
When MO status = Done, costs are recalculated based on actual usage.
Note: If the ingredient’s In stock is 0, the Default purchase price is used as a placeholder. If completed while stock is still zero, the cost used will be 0 (not recommended).
You can also manually:
Add or remove ingredients directly in the MO if changes are needed.
Operation costs
These come from the Production Operations tab on a product’s item card.
Cost formula:
Operation Cost = Actual Time × Cost per HourYou can edit Cost per Hour by clicking the cost field on the MO.
If an operation is marked as Completed without any time logged, Katana uses the planned time as the actual time.
Cost behavior for partially completed MOs
When a MO = Partially complete:
Katana uses planned costs based on planned ingredient quantity and operations time.
These appear as the Total cost of production.
When MO status changes to Done:
Katana recalculates using actual ingredients and time spent.
The actual cost is split equally across all produced units.
If a production completion date falls into a closed inventory period, the cost will not recalculate. Katana will lock in the total cost at that point.
Where to view cost per product
Go to:
Stock screen > Products table > Value in stock or In stock column > Inventory Intel
Inventory intel:
There you'll find:
Cost / Price per unit
Productions with reference to MOs
Completed quantities
Depending on MO status:
Partially complete → Shows Total cost of production
Done → Shows Actual cost per unit
Summary of cost calculations
Scenario | What Katana uses |
MO Open | Planned quantity & average cost |
MO Done | Actual quantity & time spent |
Ingredient out of stock | Default purchase price or 0 |
No time logged for operation | Planned time |
MO completed in closed inventory period | Total cost used, not recalculated |
