Is this fully automated?
Not everywhere, and we will not claim it is. Where a marketplace publishes an API we push directly; where it hands out a spreadsheet template we deliver a validated, upload-ready sheet and you click upload. The platform matrix above says exactly which is which for every platform we support.
Do you need my seller-panel login?
Never. We work through API partner or developer access where the marketplace allows it, and through your own upload button where it does not. Nobody here types into your seller panel.
What happens when a marketplace rejects a listing?
Pre-flight validation catches most rejections before upload — missing mandatory fields, wrong vocabulary values, images outside the rules. Anything that still comes back is fixed in the revision round included with the build. Approval itself is the marketplace’s decision, not ours.
Do I need GTIN or EAN codes?
For some marketplaces, yes. We check your data for identifiers before the build starts and tell you which SKUs are missing them, so you can source them or apply for an exemption with the marketplace before you pay for a build that cannot go live.
Can you work with my existing style-code structure?
Yes — that is the point. Style code, lot, colour and size the way you already keep them. We build from your structure and never regroup or rename it to suit ourselves.
Do you do photography?
No. You supply the photos; we rename, organise, resize and render them to each platform’s ratio and background rules, and we flag the ones that will not pass.
I only sell on my own store. Is there a simpler version?
Yes — the Shopify Catalogue Agent builds the same catalogue as drafts inside your own store through the official API, then keeps prices, stock and new batches in sync.
