Your products are the goods, digital downloads, services, and gift cards that you sell. You add a product in Shopify by entering product details and uploading product images. If your product has options, like size or color, then you can add a variant for each combination of options.
When you are adding or updating a product, you can make the product available to one or more of your sales channels.
You view, add, update, and organize all of your products and variants from the Products page in the Shopify admin.
From the Shopify POS products screen, you can find products and add them to the cart by browsing your catalog, using the search button, or changing the collection that you're viewing. If you have multiple locations, then only the products stocked at your Shopify POS device’s assigned location are available for sale (in the products view).
