Your products are the merchandise 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.
After you add a product in Shopify, you must also make it available to the POS sales channel so that you can see it in Shopify POS.
You view, add, update, and organize all of your products and variants from the Products screen 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 device’s assigned location are available on to add to the cart.
