# Clearly differentiate between an offer and a product in Cdiscount Flux

To better understand how Cdiscount works, it is important to distinguish between a **product** and an **offer**.

#### A Simple Example

Imagine you are looking at a T-shirt displayed in a store window.

The T-shirt itself is the **product**. It has characteristics such as:

* Name
* Description
* Images
* Brand
* Features

Once you enter the store, you may find the same T-shirt available in different sizes, colors, and prices.

These are the **offers** associated with that product.

#### How It Works on Cdiscount

The same principle applies on Cdiscount:

* A **product** contains all the information that describes an item.
* An **offer** contains the information that allows a seller to sell that item.

Marketplaces manage these two types of data separately.

### Product

A product represents the item itself and typically contains:

* Title
* Description
* Images
* Brand
* Features and specifications
* Product identifiers

### Offer

An offer represents a seller's commercial information for a product and typically contains:

* Seller reference (SKU)
* Price
* Available quantity
* Condition (new or used)
* Delivery information

### Matching: Linking an Offer to an Existing Product

On Cdiscount, if a product already exists in the marketplace catalog, you do not need to create it again.

Instead, you can create an **offer** and link it to the existing product. This process is called **matching**.

When matching is successful, your offer becomes available on the existing Cdiscount product page, allowing you to sell the product without creating a new product sheet.

**Example:** If a product already exists on Cdiscount, you only need to submit your price, stock, and seller reference. Cdiscount will associate your offer with the existing product automatically through the matching process.

### Summary

| Product | Offer |
| ---- |
| Describes the item itself | Describes how you sell the item |
| Contains images, descriptions, and features | Contains price, stock, and seller information |
| Shared by all sellers | Specific to each seller |
| Created only when the product does not exist in the catalog | Created whenever you want to sell a product |

This distinction is essential when using Cdiscount Flux, as product creation and offer matching follow different processes.
