Costing (FIFO & COGS)

This chapter covers Costing (FIFO & COGS). The pages are listed in the order you'd usually need them: how it works first, then the tasks, then the reference pages.

To…	Go to…
What a FIFO layer is, how layers are created and consumed FEFO-then-FIFO, how cost of goods sold is realized on fulfillment, and the best-available-cost sourcing hierarchy	FIFO layers & how COGS is realized
The three cost-correction paths, the single dated revaluation ledger they all funnel through, the locked-period policy, and how corrected cost feeds the accounting COGS report and GL reconciliation	Correcting COGS: revalue vs rebuild vs recalculate
Browse, search, and filter the FIFO Layers list, open a layer's detail, archive and unarchive layers, and recalculate landed-cost totals	Browse & manage FIFO layers
Correct the cost on one FIFO layer or many by choosing a COGS source or a manual value, use the per-product revaluation tool, and audit every change in the revaluation ledger	Revalue COGS (single, bulk & the COGS report)
Review the SKU COGS Health dashboard, rebuild COGS for one product or a selection, run the all-tracked background rebuild, and export cost changes	Rebuild COGS & the SKU COGS Health dashboard
Fix a unit cost after a purchase order is received and closed — the FIFO layers, average cost, and realized COGS update automatically, with no Recalculate	Correct a cost on a received purchase order
Capture a late freight or service invoice against a received purchase order — the FIFO layers, average cost, and realized COGS update instantly, and every change is recorded as a revaluation	Add a landed cost after receiving
Look up every FIFO layer quantity, cost, and lot field, the dated revaluation-ledger row, the availability lifecycle, and the COGS-source, reason, and allocation-strategy enums — plus the write guards that protect them	FIFO layer fields, statuses & enums
