The Build International Listings (BIL) tool helps brands develop and create offers in a “source” marketplace and expand these offers out to “target” marketplaces.
For some sellers, this can make managing offers across multiple marketplaces simple. When you manipulate a product listing in the source account, target marketplaces are automatically updated. But this tool doesn’t always work properly. There are often issues with listing and pricing updates appearing correctly.
If you intend to sell the same products across multiple marketplaces it may be worthwhile experimenting with BIL for a single ASIN. If it works seamlessly, fantastic – go ahead and use BIL for more products. But if you run into headaches, you may be better off managing each account independently without connecting them via Amazon Global Selling.
