There are many advantages of gathering your products in one account. You will gain easier access and there are less information to remember to update.
There are two ways to gather your products.
If you want to move a single product to another account, it is done from our control panel in the Administration menu with "Change account". Here the product is moved to another account.
If you want to move all products from one account to another, this is easily done from our control panel in the Master data menu with "Merge accounts". Here the opposite account is removed and all products moved to the current account.
Note that changing the account requires knowledge of the access information for the opposite account and product.
