How is Zero Cost Inventory Handled?
If inventory is added or received at $0, that quantity is ignored for average price and valuation purposes.
The only way stock gets added at $0 is if you import inventory or specify a $0 cost at add or receive time.
50 scanners x $300 = $15,000 (from the 1st)
50 scanners x $320 = $16,000 (from the 8th)
1 scanner was found and added to inventory at $0
50 scanners x $315 = $15,750 (from the 15th)
-----------
$46,750 / 150 = $311.67 average cost
