About the AddOnce
AddOnce helps merchants offer optional add-ons and companion products directly on product pages. Using native Shopify products and variants, you can create add-on products once and attach them to unlimited products where they belong.
Customers select optional products and services before adding items to cart. Each selection appears as an independent cart line, so inventory tracking, variants, and fulfillment work exactly as expected with native Shopify functionality.
The app automatically supports both single-variant and multi-variant companion products. Built as a Theme App Extension, AddOnce has zero impact on your storefront performance until you enable it. Present relevant add-ons where customers need them and let shoppers customize their purchases with optional products that complement their main selection.
