Three ways in. One pipeline on the other side.

A supplier item ID, a product page you found while browsing, or another seller's listing. Whatever the door looks like, the product lands in the same place and gets the same preparation.

Sourcing does not start in one place. Sometimes it is a supplier catalogue, sometimes a product page somebody sent you, sometimes a listing that is outselling you and that you want to compare against honestly. A tool that accepts only one of those makes you convert the other two by hand, every time.

The three ways a product arrives.

By supplier item ID — The supplier's own identifier. The full variant structure and image set come with it.
By product page URL — A product page from a supplier you are not connected to. We read the page and turn it into the same clean product shape as any other import.
By another seller's listing — An eBay item ID from somebody else's listing. Useful for seeing what is being sold, what it costs and how it is described — before you decide to compete.

What a load actually looks like.

01. Fetch — The product data comes in — title, variants, attributes, prices, images. What is missing is reported, never filled with guesses.
02. Enrich — The system looks up and checks article number, weight and dimensions. It proposes plausible values; the rest stays empty and says so.
03. Prepare — We clean and compose your lead image to your template, and write a listing draft for the marketplace you sell on.

On duplicates — what is and is not caught.

As images come in, duplicates are caught — the same photo arriving twice takes only one slot and one run. 40thieves matches products to existing catalogue entries by article number first, then by meaning across languages, with a review step when the match is not decisive.

What does not happen is a duplicate being blocked before it reaches your catalogue. Duplicates are flagged during review, after the import. That matters if you are deciding how much to trust the first screen: it is a review aid, not a gate.

Questions, answered

Can I import from a supplier I am not connected to?

Yes, through a product page URL. We read it and turn it into the same product shape as a connected supplier — images, data checks and listing draft behave identically.

What does it do with a listing from another seller?

It imports the product data and images so you can see what is being sold and at what price. It does not copy their description; we write the draft for your own listing.

How does it decide two imports are the same product?

First by exact article number where one exists, then by meaning — a multilingual model compares the products, with the article number as a bonus when both sides have one.

What happens when the fetched data is incomplete?

The missing field stays empty — and says so. A guessed weight would become a wrong shipping cost later, and that error would be much harder to trace back.

No connection needed for that one. The pipeline is the same as for a connected supplier.
