All actions are performed in a developer account on CS-Cart Marketplace. If you do not have one, please apply for it using the form.

1. Log in to your developer account.

2. Go to the Products → Products page and click the Add product button.

3. Fill in the following fields on the General tab.

  • Information:
    • Name ━ name of the add-on must fully reflect its features.
    • Categories ━ specify one or more categories for your add-on to make it easier for customers to find it. To choose the most relevant category, click the corresponding radio button.


  • Price ━ the cost of the add-on on CS-Cart Marketplace and on the developer's website has to be the same. If the price of your product depends on some options, please specify the base value and add the options to your add-on here, on CS-Cart Marketplace. Make sure to change this value every time you your price policy changes.
  • Do not show price ━ check the box if your add-on is only sold as a part of an add-on pack/integration, and is not sold individually. Enter the approximate cost of your add-on for it not to fall into the list of free products.
  • Live demo URL ━ if you have an active demo version of your add-on, enter the link here.
  • Full description ━ add the full description of the add-on to help customers find out about the advantages of your product. In this field you can include:
    • images;
    • videos;
    • links to resources on your website (documentation, setup instructions, demo URL, etc.);
    • developer contacts.

Most of the customers are English speakers, so we highly recommend adding a full description in English. Full description in Russian is optional. You can choose a language in the upper-left corner, but you can only do it after you save the add-on.

You can also use HTML code in add-on description.

  • Images ━ add an icon of your add-on and any additional images for the product. Required icon settings:
    • aspect ratio - 2.5x1;
    • minimum resolution - 350x140 pixels;
    • PNG format.

Using labels such as Free, Best, etc., is prohibited and regulated by the administration of CS-Cart Marketplace.

If you don't have a suitable image, you can make it by reading the article about add-on icon requirements first.

  • Pricing/inventory:
    • List price ━ if this value exceeds the regular price, a discount will appear on your add-on page. The discount is equal to the difference between those values.
  • Meta data:
    • SEO name ━ please do not change the data in this field.
    • Page title ━ enter the name of the page which will be displayed on the browser tab.
    • Meta description ━ add a meta description to help search engines easily find your product.
    • Meta keywords ━ add meta keywords for your add-on.
  • Extra:
    • Short description ━ this description will be displayed in the product list. If you leave this field empty, the first characters of the full description will be displayed as a short one.
    • Popularity ━ the popularity rating based on how many times the product has been viewed, added to cart, and purchased. 
    • Search words ━ a list of words by which the product can easily found in the built-in search tool.
    • Promo text ━ brief description of  your add-on (up to 130 characters). Promo text is displayed on the quick product preview.

5. Proceed to the following tabs:

  • Product packages ━ upload the add-on files. If you have correctly built packages of different add-on versions, you can automatically create upgrade packages. Those upgrade packages will be available on the Administration → Update center page in the admin panels of your clients’ stores. The CS-Cart documentation has more information about Upgrade center.


As soon as you upload at least one package for the add-on, it will be available for sale on CS-Cart Marketplace. Do not forget to pre-configure your payment methods.


  • Variations ━ add your product to a variation group or add your own variations.

    • Free ━ check the box if your add-on is available for free.
