Add the checkout upsell (Shopify Plus)
Offer one more product inside checkout. It needs Shopify Plus and the Pro plan, plus a block placed in the checkout editor.
The Checkout upsell template offers one more product inside checkout, for example a travel size. Apps can add blocks to the information, shipping and payment steps only on Shopify Plus, so the template needs Shopify Plus. It also needs the Pro plan.
- Create the offer from the Checkout upsell template. Its steps are Setup, Trigger, Products, Discount, Eligibility, Placement, Schedule & limits, Currencies and Review.
- On Placement, select Open checkout editor. Shopify opens the checkout editor in a new tab.
- Add the Checkout upsell block, and paste the offer ID into it. The Placement step has a copy chip for the ID once the draft is saved.
- Save in the checkout editor, then publish the offer.
Things to know
- The Placement step shows Requires Shopify Plus. If your store is not on Plus, Review says: Your store isn't on Shopify Plus, so this upsell can't show in checkout steps.
- The block shows nothing when the checkout currency differs from your store currency.
- Also see the Checkout and thank-you card on the Installation page.
