Getting your products live faster every time you start selling on a new marketplace

You manage a catalog of several hundred references. You’ve just decided to start selling on a new marketplace. Amazon, Cdiscount, Fnac, or any other platform. First step before you can sell: create the product listings. Title, description, photos, technical specifications.

A long, repetitive process.

What you probably don’t know yet: 80% of your products already exist on marketplaces, listed by other sellers before you. You don’t need to create them. You can match your inventory directly to existing listings.

In other words, out of 1,000 references to list, 800 are already there. Only 200 require actual creation work.

The problem? Without the right tool, there’s no way to identify them manually. So sellers create everything from scratch. And lose days on work that’s already been done.

The real cost: time, not complexity

Listing a product on a marketplace isn’t technically difficult.

What’s exhausting is the volume. When you’re scaling across multiple marketplaces and hundreds of SKUs, product creation becomes a permanent bottleneck. It ties up resources, delays go-live dates, and pushes back your first sales.

And most of that time is spent on products that could have been live in minutes.

How WeTransform changes the equation

The starting point for any time savings here is simple: quickly identifying which listings already exist, so you only work on what’s actually missing.

Sellermania uses WeTransform, a tool built to accelerate product listing across marketplaces.

By cross-referencing your catalog against marketplace data, WeTransform automatically detects which products are already referenced. What you’re left with is a clean list of the references that still need to be created. No more sorting, no more searching, no more duplicating work that’s already been done.

From detection to go-live

WeTransform doesn’t stop at identification. Once the missing listings are isolated, it prepares your catalog in the right format for each marketplace, drawing on the information already present in your data. You review, you validate, your listings go live.

Less friction. Faster time to first sale. And hours recovered with every new marketplace you activate.
