What it does
Calculates true cost of goods sold — including vendor costs posted to the journal — and gross margin, per order and over time. A Reconcile This Total link traces every debit posted to the Cost of Goods Sold account back to the transaction that caused it, grouped by source, with the largest contributors listed first and anything that looks structurally off (an order whose job cost exceeds its sale price, an inventory item with an impossible quantity or cost) flagged separately.
