Cost of goods sold: what the products you sold cost you, net of restocked returns.

COGS = Σ unit cost × (units sold − units restocked) + RX lens cost

How it is calculated

  • The unit cost is the one in force on the order date. See COGS for how the cost is chosen.
  • Units returned or cancelled with a restock do not count.
  • When a print-on-demand or dropshipping provider reports the exact product cost of an order, that amount is used instead.

Reading it

  • Format: Amount in your reporting currency.
  • Lower is better (an increase is shown in red).

Where it appears

  • Overview and Dashboards — add it from the metric picker (Costs group).
