A Listing is an automatically created link in Craftybase between your product on Craftybase and the external sales channel. This linkage ensures that all data imported from the external sales channel is associated with the correct product.
A listing can only be connected with one product on Craftybase, however you can connect as many listings to a product as you like. This is really handy when you have the same product represented on a couple of different sales channels - you can then combine them together via merging to track your product in one place in Craftybase.
