How to replace Checkout Blocks upsells with UpsellPlus
Shopify ended Checkout Blocks' checkout upsell features on August 31, 2026. Product upsells, free gifts and cross-sells built in Checkout Blocks no longer show at checkout. UpsellPlus can rebuild all of them, and we'll do the migration for you for free: no development work and no migration fee.
- Fastest option: book a free migration session
- Do it yourself: follow the steps below
- Requirements: checkout upsells need Shopify Plus. Product page, cart, post-purchase and thank-you page offers work on every Shopify plan.
Is my store affected?
You're affected if you used Checkout Blocks for any of these at checkout:

Option 1: Free migration session (recommended)
In a short call, the UpsellPlus team will:
- Rebuild your existing checkout offers and their targeting rules in UpsellPlus
- Match the design to your current checkout
- Test everything before it goes live
Option 2: Migrate yourself
- List your Checkout Blocks offers. For each one, write down the products, discount, conditions and where it showed in checkout.
- Install UpsellPlus from the Shopify App Store and open it from Apps → UpsellPlus.
- Create a checkout offer for each Checkout Blocks offer: go to Offers → Create Offer, and on the Funnel tab under Where should this offer appear? choose Checkout (or Checkout Header / Checkout Footer).
- Add products: on the Offers tab, under How should products be selected?, choose Specific Products, From Collections or Tags, or Automatic (ShopBrain) to have recommendations picked for you.
- Recreate the conditions in the Targeting section: cart value, cart products, collections, customer tags, markets, discount codes, and more.
- Recreate free gifts by choosing Free Gift on the Behavior tab. The gift is added to the cart automatically when the shopper qualifies, and removed when they stop qualifying.
- Add the UpsellPlus block in Shopify's checkout editor (Settings → Checkout → Customize) in the same place your Checkout Blocks offer was.
- Match the design using the offer's styling options or Design Mode.
- Test on a draft checkout profile, then publish.
