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.

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.

Step-by-step: Set a single CoG
Step 1: Find the SKU
→ Open directly in the app: app.arbitrageone.de/cog
Use the DataTable search field at the top left to find the SKU.
Step 2: Add
Click Add (or the edit button in the row) and enter SKU, ASIN, purchase price (net) and prep fee (net). Via + Add row you can enter multiple SKUs in one go.
Step 3: Save
Saving applies the value immediately to all future profit calculations.
Step-by-step: Batch upload
Step 1: Prepare CSV
Create a CSV with the columns seller_sku;cost. The decimal separator is a dot (e.g. 12.50).
Step 2: Upload the file
Click Batch Upload and choose your file. You'll see a preview before the values are applied.
Step 3: Apply
Confirm — existing entries are overwritten, new ones are created.
Important notes
Values from Record Purchase take priority over manually stored CoGs. Recorded purchases don't overwrite the manual value, they are used directly.
CoG is stored in the currency of your home marketplace.
Sellerboard migration: export the SKU/CoG list there as CSV and use the batch upload.
Common issues
Issue: "My CoG is ignored in ProfitTracker." Solution: A recorded purchase probably exists for the SKU — it takes priority. Check your purchases or delete the wrong entry there.
Issue: "Batch upload throws an error." Solution: Often the wrong separator or a comma as the decimal separator. Check the format with a text editor.
