Custom products are easy to make, however they come with a few limitations. Due to our current system infrastructure, it is not possible to list any custom products on Amazon or TCGPlayer. This makes them a great solution for any product that you intend to sell only in your store, on your direct website, or on eBay.
To Create a Custom Product:
In your admin, navigate to Inventory => Products.
Here, search for the category that you would like to create the custom product within.
In the heading of the list of products, there is a blue plus button. Click this to open the New Product dialog box.
From this page, you can edit basic product info, as well as input values for any descriptors associated with the product type assigned to this category. You may also upload images, and add a custom description for the item.
