Costing (FIFO & COGS)

Every unit you receive carries a cost in a FIFO layer, and that cost becomes your cost of goods sold when the unit ships. Read the two concept pages first: one on how layers work, one on choosing the right correction. Then use the task pages to browse layers on Inventory → FIFO Layers, revalue or rebuild costs, and apply late supplier price changes or freight bills to stock you've already received.
