How to Handle Multiple Amazon Regions/Marketplaces and International Shipping
The plugin supports international fulfillment through FBA as long as your FBA policy allows it. You have to have the international export services active on your Amazon Seller and FBA account. However, you can also use the settings to turn OFF international fulfillment, and the plugin will not send orders to Amazon which have a destination address outside your home country as configured in the normal WooCommerce settings.
Does it support multiple Amazon Regions and Marketplaces at the same time?
No. You can only connect to one Amazon Region and Marketplace per WooCommerce site.
Supporting multiple regions and marketplaces simultaneously from a single site is something we’re considering for the future, but there are many challenges with that.
For example, every region and marketplace has different inventory levels for the same SKU but your WooCommerce product only has 1 stock level. Syncing the level with one marketplace that is out of stock would make the product unavailable to other marketplaces even if they had stock available.
For now, we recommend using International fulfillment with FBA from a single home region, or having 1 site per region to connect to unique Amazon Seller Central accounts.
