When inventory valuation looks wrong, we do not begin by changing the total.
Confirm the Cost Method
Sage supports standard, average, FIFO, LIFO, lot, and serial costing methods by warehouse.
The cost method establishes the framework for understanding the value Sage is carrying.
Separate Quantity From Unit Cost
Is the unexpected total caused by the wrong quantity? The wrong cost? Or both?
That distinction narrows the problem quickly.
Check the Warehouse
Because Sage can assign costing by warehouse, the same item may need to be investigated in the specific location where the valuation difference appears.
Follow the Transactions That Built the Value
Receipts, issues, sales, adjustments, transfers, production, returns, and other inventory activity can affect the layers or values behind the item.
We narrow the report until the total becomes a set of transactions we can explain.
