- Add optional add-ons with native Shopify products
- Create once. Attach to unlimited products.
- Customers add each selection as independent Shopify cart lines
- Automatically supports single- and multi-variant companion products
- Theme App Extension with zero storefront impact until enabled
Attach optional add-ons using native products and variants.
AddOnce lets merchants present optional products and services directly on the product page. Create a Companion Product once, then attach it to any product where it belongs. Because AddOnce uses native products, inventory, variants, and fulfillment continue to work as expected. Customers choose optional add-ons before adding to cart, and each item is added as its own native cart line.
