# How to Create and Update Stock Lists in Omnitron?
In this page, adding or editing stock list processes within Omnitron is explained.
## Step 1: Access to Omnitron
* Access the Omnitron panel.
* Enter your username and password, then click the **SIGN IN** button.\
## Step 2: Navigate to Stock List Page
* Follow the Product and Catalogs sidebar and click the **Stock List** page.
* On the **Stock List** page, filter panel and the list of stock lists are displayed.
## Step 3: Add a New Stock List
* To create a new stock list, click the **+New Stock List** button located in the top right corner of the Stock List page.
* **Enter Stock List Name:** Different stock lists can assign various values to a product. For example, a product can be priced at X amount in Stock List A, which is designated for Marketplace A, while it can be sold for Y amount in Stock List B, designated for Marketplace B. Therefore, when creating or updating a product's stock, it's essential to specify the relevant stock list.
* **Select ERP Connection:** Select between 'Yes' or 'No'. If 'Yes' is selected, stock creation and updates can be performed through integration. If 'No' is selected, the stock creation and update processes are managed using Excel through the Omnitron back-office.
* After entering this information, click the **Save** button to create the new stock list. For detailed information on creating a stock list using an API, refer to [this page](https://apidocs.akinon.com/omnitron/integration/stock/stock-list).
## Step 4: Update Stock Lists
* To access the details of the listed stock lists, click on it.
* On the Stock List page, filters and products are listed. The filter panel provides options for filtering by product types, include and exclude filters, or filtering the product pool using **.CSV** and **.XLS** files.
* To ensure the accuracy of the parameters within the uploaded file, it is recommended to download the stock list template from the bottom of the page first. Once product information is added to the template, bulk product updates can be performed by either dragging and dropping the file or clicking on the designated area and selecting the **.CSV** or **.XLS** file format.
* By clicking the **+Update Stock List** button, a file in the designated area can be uploaded by users.
* After the file is uploaded, the update process will be completed with a progress bar for users to monitor.
* Once the process is complete, the page will be refreshed, and the updated values will be displayed.
