Understanding the Difference Between Offers and Products (Cdiscount)

Simple example

You are looking at a store window: a T-shirt catches your eye.
What you see in the window is the product (the sheet: description, images, features).

You enter the store: that T-shirt exists in several sizes and colors, sometimes at different prices.
Those are the offers.

On a marketplace, the principle is the same:

• the product sheet is shared (Cdiscount / Octopia catalog);
• each seller publishes their own offer (price, stock, shipping, condition).

Definitions

Product (catalog sheet)

• Title, descriptions, images, features, marketplace category
• Usually identified by an EAN / GTIN
• Created via the module in Catalog > Cdiscount > Creation / Product Integration

Offer (seller listing)

• Seller reference (SKU = PrestaShop Reference)
• Price, stock, condition (new / used)
• Shipping fees / delivery modes, preparation time
• Updated via Catalog > Cdiscount > Offers / Offer Integration

Matching

If the product already exists on Cdiscount (known EAN), you can publish only an offer linked to that product: this is matching.

If the product does not exist yet, you must first create the product sheet, then send the offer.
Otherwise you typically get: “Unknown reference / you must create your product”.

In PrestaShop

PrestaShop does not separate “product” and “offer”: everything is a product sheet (with optional combinations).
The module turns these sheets into:

• product data for Octopia (creation), and/or
• offer data (price / stock / shipping).

What next?

Read: Is it necessary to send my products?

Useful reminder:

• Stock & Price Light → mainly updates stock/price (does not correctly recreate a full offer / shipping)
• Full Package → full offer send (create / full update, including shipping and lead time)
