Short description
CoG (Cost of Goods) is the purchase price ArbitrageOne uses to calculate your profit. By default the system uses the values from your recorded purchases. For SKUs without a purchase entry — e.g. from old stock or Sellerboard imports — you can store the CoG here manually.Page layout
Notice at the top
By default, calculation uses the purchase prices for which a purchase has been recorded in A1. If no purchase exists for an SKU, the values stored here are used as the purchase price.
