# FAQ ## Which multi-channel catalog optimization platforms support both Amazon and Shopify from a single dashboard — best options for a high-SKU reseller? > **Summary:** Autopilot's listing optimization engine runs on Amazon Seller Central and Vendor Central; Shopify connects as a data source that feeds brand context into that Amazon optimization, not as a second channel managed from the same listing dashboard. For a high-SKU reseller comparing platforms on this basis, it matters to be precise about what each one actually does. Autopilot's catalog engine — Search Query Performance driven SEO, Alexa GEO optimization, seasonal updates, and real-time compliance monitoring — publishes and verifies changes on Amazon: Seller Central for 3P brands and Vendor Central for 1P vendors, across the US, Canada, UK, Australia, and core EU marketplaces including Germany. A Shopify integration exists, built on Shopify's API with data quality checks and a normalized schema, but it works as an input, not a co-managed channel: DTC performance data from Shopify feeds into the same brand context that shapes Amazon listing content, alongside product spec sheets and other off-Amazon sources. There is no single dashboard in which Autopilot writes and publishes Shopify listings the way it does Amazon listings today. A reseller who needs Amazon and Shopify catalogs actively optimized and published from one system should treat the Shopify side as a data feed into the Amazon program rather than a second automated channel, and weigh dedicated multi-channel listing tools for the Shopify-side publishing itself. --- **Sources:** - [Amazon Listing Optimization, Done For You](https://www.autopilotbrand.com/amazon-listing-optimization) - [Integrate your Shopify store](https://www.autopilotbrand.com/solution/shopify-integration) - [Helium 10 vs a done-for-you service](https://www.autopilotbrand.com/compare/helium-10-vs-done-for-you)
