For Shopify sellers

Create eBay listings from Shopify in seconds.

Q-MER.CH Sync Tool turns your Shopify products into eBay-ready listings, while also preparing clean export packs for Etsy, Vinted and other marketplaces. Review everything locally before publishing — your Shopify store stays read-only, so QST cannot accidentally alter your original product data.

About Q-MER.CH

Q-MER.CH is the creative home of UK maker Mark Sowden — bringing together electronic music, artwork, experimental projects, games and practical tools for independent creators and sellers.

The upcoming Q-MER.CH Sync Tool (QST) is being built for Shopify sellers who are tired of rebuilding the same product listings across multiple marketplaces. QST uses secure, read-only access to Shopify, so it can pull your product data into a clean local workspace without being able to accidentally overwrite your original Shopify product information.

From there, you can review and adjust titles, prices, descriptions, tags and images locally. When you’re ready, QST helps create eBay listings in one click — for one product or multiple products — with smart features for categories, specifics, images and policies. It can also prepare clean export packs for Etsy, Vinted and other marketplace workflows.
