Overview

Amazon's Build International Listings tool allows sellers to expand their product catalog across multiple global marketplaces by connecting offers from one primary storefront to others. A key step in this process is selecting which marketplace will serve as your source (the primary hub for pricing and catalog management) and which marketplaces will be your targets (where connected listings will automatically appear). Getting this decision right is essential for efficient international selling.

Key Points / What Sellers Need to Know

• Source marketplace drives pricing — The marketplace you designate as your source becomes the master reference for pricing. Any price changes you make there will automatically propagate to all connected target marketplaces.
• Choose your busiest marketplace as the source — Amazon recommends selecting the marketplace where you have the most active offers, since it will serve as the control center for your international listings.
• Target marketplace offers sync automatically — Once connected, product listings in target marketplaces will mirror your source pricing, adjusted by any price rules you configure.
• Deleting existing target offers is irreversible — If you choose to delete existing offers in a target marketplace during setup, all associated offer history and reviews will be permanently removed.
• Price updates can take up to four hours — After changing a price rule or source price, expect a delay before the updated pricing appears in each target marketplace.

How Source Marketplace Selection Works

When you begin setting up Build International Listings, the first decision is picking your source marketplace. This is the storefront Amazon treats as your primary catalog and pricing hub. If you currently sell in only one marketplace, the choice is straightforward — that marketplace becomes your source. Sellers operating across multiple marketplaces should generally select the one with the largest number of active offers, as this minimizes the amount of manual setup required. You can also designate a second source marketplace if you manage separate catalogs across different regions. When adding a second source, the tool displays your existing source and target selections on-screen for easy reference, and only marketplaces not already assigned will be available for selection.
