PIM has **one shared catalogue** used by every EcomCart PIM customer. EcomCart maintains it, and supplier data flows into it.

When you edit a product, your edits are stored **separately** — as **your changes** (technically an "overlay"). Your store uses your value; everywhere else the catalogue value stays.

## Why this is useful

- You can adapt texts to your style without breaking data for others.
- When a supplier updates its data, your edits **stay**.
- Fields you haven't changed automatically get the latest catalogue data.

## Where to see your changes

On the product card click **Your changes** (or **⋯ → Your changes and publishing** in the list). The page shows:

- **Texts** — the catalogue value next to yours;
- **Properties** and **dimensions** — the same;
- **Image selection** — which catalogue images to show, in what order, and which is the main one;
- **Publishing per channel × language**.

If a field has no edit of yours, it shows **— no override —**.

## How to go back to the catalogue value

1. Open **Your changes**.
2. **Empty** the field with your edit.
3. Click **Save overlay**.

The field shows the catalogue value again. Image selection has a **Revert to base** button.

## Images

You can't upload your own images — images are shared by all stores. You can choose **which** catalogue images to show, their **order** and the **main image**. If a product is missing an image, contact support.

## Status in assortment

PIM tracks whether you've changed a product:

- **Selected** — the product is in your assortment without your edits;
- **Enriched** — you've added your own changes;
- **Off** — the product is in your assortment but not used (not published).
