How to Change Your Source Marketplace in Build International Listings
Explains how to change the source marketplace in Amazon's Build International Listings tool, including the required steps of removing existing connections, waiting for processing, and creating new connections with a different source.
Overview
Amazon's Build International Listings (BIL) tool allows sellers to synchronize product offers across multiple global marketplaces from a single source marketplace. Occasionally, sellers may need to change which marketplace serves as their source — whether due to shifting business priorities, expanding into new regions, or consolidating operations. This guide explains the process for switching your source marketplace and the key considerations to keep in mind.
Key Points / What Sellers Need to Know
- Source marketplace drives synchronization — Your source marketplace is the primary storefront from which pricing, inventory, and offer details are pushed to connected target marketplaces. Changing it affects all synchronized listings.
- You must remove existing connections first — Amazon does not allow a direct swap of source marketplaces. You need to disconnect all current target marketplace connections before establishing new ones with a different source.
- Processing takes up to four hours per marketplace — Each disconnection request can take up to four hours to complete, so plan accordingly if you have multiple target marketplaces linked.
- Email confirmations are sent — Amazon sends an email notification when each removal request finishes processing, so you know when it is safe to proceed.
- Wait for all removals before reconnecting — Creating new connections before existing removals are fully processed can cause errors and synchronization issues.
How the Process Works
Changing your source marketplace is a two-phase process. In the first phase, you remove all existing connections between your current source marketplace and every target marketplace it feeds. You do this through the Build International Listings settings in Seller Central. Once you initiate the removal, Amazon begins processing each disconnection individually. Each marketplace removal can take up to four hours, and you will receive a confirmation email for each one as it completes.
In the second phase, after every removal has been confirmed, you create a new connection through the same Build International Listings interface. This time, you select your desired source marketplace when setting up the connection. You then choose which target marketplaces should receive synchronized offers from this new source. The tool will begin synchronizing your listings from the new source marketplace once the connections are established.
