You can open the Network page via your profile picture at the top right of the header, after that select “My network”.
In the Network page, you can see the companies that are linked to your company’s account. This is also the place where you can add new business relations to your network, more about that here.
Admin users can, if needed, add/change the account code of your relations. Make sure the account code you enter here is the same as the account code your contact is known in your ERP system. Based on this code Tradecloud matches the order (response) message from your ERP to the correct company in Tradecloud.
