What is a SKU on OTTO?
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
The SKU is the ID you give an item yourself, and OTTO lists the item under it.
It isn't the manufacturer's EAN, and it isn't the number OTTO itself assigns to the item. MargenOptimierer recognizes every item by its SKU. In the tables it's in the Produkt (SKU) (product, SKU) column.
Example: SKUs for table and chair
Say the 180 cm oak table has the SKU TISCH-EICHE-180 and the acacia chair has the SKU STUHL-AKAZIE-01.
The SKU when you import
When you import from a file
If you enter costs through a file, the „SKU“ column is required. MargenOptimierer uses it to match each row to its item. A SKU that MargenOptimierer doesn't know appears in the preview as „SKU unbekannt“ (SKU unknown).
