Shopify Marketplace Connect uses your Shopify product data as the system of record. Maintain your product data all in one place and let us sync with all your marketplace listings.
This is a better approach than maintaining product data directly on marketplaces because it can be lost if your account gets suspended.
It's also quicker to update data in Shopify using Marketplace Connect.
