rheo on ce-net

Enter it once. We list it everywhere.

You enter each item once, the way you do now. We write the listing for each marketplace in its own format and language, prepare the photos, fill in the forms and set up the seller accounts with you. When an item sells on one site, we take it off the others.

List three items free What it costs

What we do

One stock row, five marketplaces to start.

Mockup with CAD renders of our own square Huey head: the Huey kit written as one listing for eBay, Tindie, Etsy, Tradera and Blocket
Mockup, not live listings: our own Huey robot kit written once for eBay, Tindie, Etsy, Tradera and Blocket, each in its own title style, language and currency.
  1. You send your stock.A spreadsheet, an export or photos. Tell us where you sell today.
  2. We write and post.Each site gets its own text, photos, category and price. We fill in every form.
  3. Sold on one, gone on all.When something sells, we take it off the other sites.

First marketplaces: eBay, Etsy, Tindie, Tradera, Blocket. Next: Amazon, Facebook Marketplace, Vinted, Kleinanzeigen.

Price: no fixed fee. You pay a share of each part when it sells, nothing before. We list three of your items free first, so you see the result.

You keep every seller account and every login. We work inside accounts you own; opening an account needs your own ID on each marketplace, and we fill in the rest.
