What is an in-checkout upsell? An in-checkout upsell is an offer shown inside Shopify’s native checkout flow, before payment completes. Zipify One Click Upsell (OCU) adds up to 8 SKUs of in-checkout offers with split testing, built directly into Shopify’s checkout editor on Shopify Plus.
Checkout is the highest-intent moment in the funnel. The customer has selected a product and entered payment, actively completing a purchase, so a single relevant add-on captures incremental revenue right when buying intent peaks. It’s available today on every Shopify Plus store.
Zipify OCU’s In-Checkout Offer runs inside Shopify’s checkout. It supports:
In-checkout is built into Zipify OCU, not a separate purchase or a second subscription. Some Shopify Plus upsell tools price checkout offers as an add-on or sell them through a dedicated app just for that placement. With Zipify OCU, it’s one of six placements included in the same plan, so there’s no extra app to install or additional setup to configure before it’s live.
Product Page: Product Page Offer Widget, up to 8 SKUs, split testing.
Slide Cart Drawer: Cart drawer replacement with free-shipping reward bar, up to 8 SKUs.
Pre-Purchase Popup: Single, upgrade, multi-product (up to 5 SKUs), same-product, and Dynamic AI offers.
In-Checkout (this guide): Up to 8 SKUs, split testing, built into Shopify Plus checkout.
Post-Purchase: One-click accept, single, multi-product, same-product, Dynamic AI, and downsell-on-decline.
Thank You Page: TY Page Offer, plus PostProfit (free built-in ad revenue feature).
Zipify OCU runs all six placements, including in-checkout, in one system. For the full picture, see the complete 2026 upsell playbook.

Does an in-checkout upsell require Shopify Plus?
Yes. In-checkout offers run on Shopify Plus, built into the checkout editor.

No. Zipify OCU’s In-Checkout Offer installs and configures directly inside Shopify’s standard checkout editor.
How many products can I offer at checkout with Zipify OCU?
Up to 8 SKUs, with split testing to see which products and offer content convert best.
Does the customer need to re-enter payment info to accept an in-checkout offer?
No. The offer adds to the same order the customer is already completing, in one click.

Yes. Zipify OCU runs all six placements, including in-checkout, pre-purchase, and post-purchase, in one funnel builder, each tracked and split-tested independently.
