Get alerted on first storefront installs, review spikes, pricing changes, and listing edits.
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.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows AddOnce on a store, it is there.
