What marketplace sellers should look out for

With three marketplaces, stock sync is the most important criterion: if an item sells on eBay, stock on Amazon and Kaufland must drop immediately. Reserving stock when an order comes in is even safer – you'll find it under “Special requirements”.

Also watch out for channel limits in entry plans: some plans only allow one marketplace or a maximum of three channels. The finder takes this into account automatically and chooses the right plan.
