Your product catalog is a shop page that reflects all the available products you have in Simplero (that are set to Listed). This can be added as a page on your site, or as a section on a page on your site.
NOTE! The Product Catalog section is only available on pages with the Legacy Builder. If you’re using a page with the 2.0 Builder, you can read about your options in this help guide.
There are 3 types of products:
Listed - this product will display in your catalog. Everyone can get to it.
Unlisted - this product will not display in your catalog, but is still available for purchase. In other words, you will need to give someone the URL to purchase.
Closed - not available for purchase, not listed anywhere.

Before you add any product to your product catalog you will need to configure the product itself first.
