About Q-MER.CH

Q-MER.CH is run by UK creator Mark Sowden — husband, dad, and proudly adult-diagnosed ADHD. It’s the home for his electronic music project Q-MARX, alongside a growing collection of creative work.

The upcoming Q-MER.CH Sync Tool (QST) is built for sellers who are tired of rebuilding the same listings over and over, removing friction from multi-platform selling. Using secure, read-only access to Shopify, it safely pulls your product data into one clean local workspace, where you can edit titles, prices and descriptions. When you’re ready, publish to platforms like eBay in a single click — no copy-pasting, no duplicate work, no mistakes. Faster listings, fewer errors, and full control — without touching your live store.
