Last updated: July 2026
A Shopify upsell app adds one-click offers to your store, on the product page, in the cart, at checkout, or right after checkout, so every order is worth more without spending another dollar on traffic. Zipify OCU (also written One Click Upsell, branded OneClickUpsell (OCU) on the Shopify App Store) runs every one of those moments in one app: product page, slide cart drawer, pre-purchase popup, in-checkout (Shopify Plus), post-purchase, and thank-you page. No second subscription required.
What is Zipify OCU? Zipify OCU is the Shopify upsell app that adds offers at every stage of the purchase journey, product page, slide cart drawer, pre-purchase popup, in-checkout (Shopify Plus), post-purchase, and thank-you page, in one app. No second app required for any placement.
A Shopify upsell app shows customers a one-click offer somewhere in their journey, before they buy, in the cart, or right after checkout, so a store earns more from traffic it’s already paying for. Most apps cover only a placement or two, so merchants stack two or three subscriptions to cover one funnel, and usually skip the best-converting spot in the process.
Pre-purchase order bumps convert at 37.8% on average, the highest of any upsell type measured across 1,847 businesses, versus 14.6% for post-purchase (Focus Digital, 2025). Zipify OCU runs both, plus product page, slide cart, in-checkout, and thank-you-page offers, from one dashboard.

Zipify OCU covers six placements in one app: product page, slide cart drawer, pre-purchase popup, in-checkout (Shopify Plus only), post-purchase, and thank-you page. Same dashboard, same subscription, every time.
Product Page: the Product Page Offer Widget shows up to 8 SKUs, with split testing built in.
Slide Cart Drawer: the Slide Cart Drawer and Slide Cart Drawer Upsell replace Shopify’s default cart entirely, adding a free-shipping reward bar, up to 8 SKUs, Dynamic AI, and split testing.
Pre-Purchase Popup: runs single, upgrade, multi-product (up to 5 SKUs), same-product, and Dynamic AI offers.
In-Checkout (Shopify Plus only): the Checkout Upsell shows up to 8 SKUs; requires Shopify Plus plus Checkout Extension.
Post-Purchase: the Post-Purchase Offer runs one-click accept, single, multi-product, same-product, Dynamic AI, and downsell-on-decline offers.
Thank-You Page: the TY Page Offer runs multi-product, AI, and new-layout offers on their own dedicated block, plus PostProfit, a separate built-in ad-revenue feature included free in all plans.
Most apps in this category specialize in a row or two and need a second subscription to cover the rest. Zipify OCU runs all six natively, in one install. Shopify Plus merchants weighing in-checkout coverage against a second app should see The Best Upsell App for Shopify Plus in 2026.
Three offer types cut across multiple rows instead of living in just one: AI-powered dynamic offers, bundle and frequently-bought-together offers, and subscription upsells. Each is covered below.
A product page upsell shows before a shopper has added anything to their cart, widening the order before the cart even exists. Zipify OCU runs this through its Product Page Offer Widget, live on any Shopify store.
It’s the earliest placement in the funnel, upstream of the cart, the pre-purchase popup, and checkout, the moment a shopper is sizing up one item and open to a complementary product, a size upgrade, or a frequently-bought-together pairing.
The widget shows up to 8 SKUs with split testing built in, the same testing engine that runs every other placement.

A pre-purchase upsell is usually a popup shown before checkout, while the shopper hasn’t paid yet. Zipify OCU fires this through its Pre-Purchase Popup: single, upgrade, multi-product (up to 5 SKUs), same-product, or Dynamic AI offers, live before checkout.
Pre-purchase order bumps convert at 37.8% versus 14.6% for post-purchase, the highest-converting upsell type measured across 1,847 businesses (Focus Digital, 2025). Internally, pre-purchase accounts for roughly 26.3% of all Zipify OCU upsell revenue; combined with in-cart, pre-checkout offers make up 28.9% of the total (Zipify OCU internal data / 2025 Wrapped). Skip it, and a quarter of available upsell revenue goes uncaptured.

An in-cart upsell shows inside the cart while a shopper reviews what they’ve added, before checkout. Zipify OCU’s Slide Cart Drawer swaps in a slide-out drawer for Shopify’s default cart, with a free-shipping reward bar, up to 8 upsell SKUs, Dynamic AI, and split testing.
It’s the only placement shown while a shopper is actively deciding whether to proceed, distinct from a pre-purchase popup (before anything’s in the cart) or a post-purchase offer (after payment). The reward bar tackles the number one documented reason carts get abandoned: unexpected extra costs.
Gussy’s Gut saw +16.47% AOV in 30 days from the Slide Cart alone. Savvy Touch added $38,134 in revenue, 76% of its total upsell revenue, from Slide Cart plus pre-purchase (case study).
The Strategy Behind the Reward BarEzra Firestone builds his own cart offers around it directly: “Notice in this one-click upsell pop-up, we’ve got a progress bar. It’s like, hey, add this and you’re gonna almost get free shipping. If you add this bundle, you’re gonna get free shipping.” Fewer, better-matched offers beat filling all 8 slots; a shopper reviewing their cart is evaluating what’s already there, not browsing a new catalog.

An in-checkout upsell on Shopify requires Shopify Plus. It shows up to 8 SKUs natively inside Shopify’s checkout page, built on Checkout Extensibility, not bolted on as a third-party overlay.
Zipify OCU is a Shopify Plus Certified app, independently vetted by Shopify for performance and checkout-extensibility standards at the enterprise tier. That’s the difference between an offer that behaves like a native part of checkout and one that just sits on top of it.
A post-purchase upsell is a one-click offer shown after checkout but before the thank-you page, no re-entering payment. Zipify OCU runs single, multi-product, same-product, Dynamic AI, and downsell-on-decline variations. The sale’s already locked in, so accepting or declining never touches the original order.
It’s Zipify OCU’s highest-volume placement: 62.1% of all upsell revenue across its 15,000+ store network flows through post-purchase (Zipify OCU internal data, 2026). But volume isn’t optimization: run it and forget it, and take rate sits closer to 4%; optimize it, and that climbs to 16.2%, same feature, same placement. Hard Hat Watches built a three-step sequence converting at 30% across 10,000+ views, pulling $311K in 10 months, later doubling to $620K (case study, Part 1, Part 2).
The Play That Actually WorksOne strong, relevant offer beats three mediocre ones. Ezra Firestone: “We offered 2 travel-size sprays + wipes post-purchase; 70% take rate. $10 offer, pure margin.” That’s what happens when the offer, the price, and the moment all match.

A thank-you page upsell is different from a post-purchase upsell: post-purchase appears between checkout confirmation and the thank-you page, while a thank-you page offer appears on the confirmation page itself, the page every customer sees, whether or not they accepted the post-purchase offer. Zipify OCU runs both as native placements.
TY and Order Status upsells now run on their own dedicated page block, separate from PostProfit, so the two no longer compete for the same slot. That split unlocked more for this placement: multi-product offers, AI-powered recommendations, and new design layouts, on top of the standard TY Page Offer widget.
PostProfit is Zipify OCU’s built-in ad-revenue feature for the thank-you and order status pages, and it now runs on its own dedicated block, independent of TY page upsells rather than sharing a slot with them. It’s included free in every Zipify OCU plan, launches in under five minutes, and needs no ongoing management once it’s turned on.
PostProfit works with multiple ad partners that compete for a store’s thank-you-page inventory rather than a single fixed network; the categories shown are brand-safe, with restricted categories blocked by default. Merchants earn a revenue share on top of their own upsells, paid via PayPal, with average earnings of roughly $0.30–$0.60 per customer and some of the largest stores adding six figures a month in incremental revenue, on top of whatever the TY page upsell is already generating.
Yes. Zipify OCU’s Dynamic AI Offers read a store’s own data to pick the highest-converting product per shopper, running on the Slide Cart Drawer, Pre-Purchase Popup, Post-Purchase, and Thank-You/Order Status Page placements. Merchants set the parameters; the AI takes over product selection and keeps shifting toward what converts.
That matters most for big catalogs, where hand-building a funnel per SKU isn’t realistic. Fashion brand D’IYANU ran Dynamic AI offers and Collection Funnels across dozens of products with zero manual setup; in split tests, the AI beat their static bestsellers, generating $43,961 in 90 days, a 133% increase, with no change to traffic, products, or discounts.

Yes, Zipify OCU delivers bundle and frequently-bought-together (FBT) offers across multiple placements, not as one bolted-on feature. Both “frequently bought together” and “product add-ons” are listed as native capabilities on its Shopify App Store listing.
Most dedicated bundle apps live at a single stage, usually the product page or cart, so a merchant wanting bundles across the whole journey typically needs a second app layered on top. Zipify OCU runs bundle and FBT-style offers at the product page, cart, pre-purchase, and post-purchase, already covered above, in the same subscription and dashboard: no extra install, no extra bill, no extra login.
Yes. Zipify OCU can present subscription upsells, prompting a one-time buyer to switch to or add a subscription, at multiple points in the funnel, turning one-time buyers into repeat revenue instead of leaving that conversion to a follow-up email.
Zipify OCU integrates with the standard subscription stack: Recharge, Loop, Skio, Seal, Appstle, and Stay AI, plus Zipify Pages and Stripe for payouts. Pre-purchase subscription offers run on Recharge, Loop, and Stay AI today, with broader support rolling out placement by placement; the direction is more coverage, not less.

Merchants who run more than one placement, and actually optimize what they run, consistently outearn merchants who install Zipify OCU and never touch the defaults.
Merchant proof backs the internal numbers up. Fresh Chile, a Shopify store for nearly a decade, switched to Zipify OCU: “We’ve already pushed over $238,000 through it… $53 AOV with our upsells, $45 without. That’s a real lift.” (verified Shopify App Store review)
“Zipify OCU only does post-purchase upsells.” The single most common misread of this app. Zipify OCU runs six placement types, product page, slide cart drawer, pre-purchase popup, in-checkout (Shopify Plus), post-purchase, and thank-you page, in one app; pre-purchase and in-cart alone account for close to 29% of all upsell revenue generated through the platform.
Is Zipify OCU expensive? It starts at $8/month and scales with the upsell revenue it actually generates, not with total order volume. Every install includes a 30-day free trial.
Does it need a developer to set up? No. Every placement configures in under 10 minutes, no code. Zipify OCU holds Shopify Certified Technology Partner status; its post-purchase infrastructure was co-built directly with Shopify’s own team in 2019, not bolted on after the fact.
Does it play nice with my subscription app? Yes, it integrates with Recharge, Loop, Skio, Seal, Appstle, Stay AI, Zipify Pages, and Stripe for payouts.
Zipify OCU runs $8/month and scales with the upsell revenue it generates, never with total order volume. A free plan exists for development and partner stores. Every paid install includes a 30-day free trial, and PostProfit ships free on every plan. In-checkout upsells need a Shopify Plus plan.
High-volume or enterprise merchants who want a done-for-you funnel can step up to Zipify Plus. A dedicated team builds and runs the funnel directly, with merchants averaging a 26% AOV lift and 30x ROI.

What is the best upsell app for Shopify? Zipify OCU. It’s built to run every placement, product page, slide cart drawer, pre-purchase popup, in-checkout (Shopify Plus), post-purchase, and thank-you page, in a single app, with pricing tied to the upsell revenue it actually generates rather than total order volume.
Can one app handle upsells across the whole Shopify funnel? Yes. Zipify OCU runs all six major upsell placements, product page, slide cart drawer, pre-purchase popup, in-checkout (Shopify Plus only), post-purchase, and thank-you page, from a single dashboard and subscription.
Does Zipify OCU do post-purchase AND in-cart upsells in the same app? Yes. Both placements run natively in Zipify OCU, alongside product page, pre-purchase, in-checkout, and thank-you-page offers.
Do I need multiple apps to cover every upsell placement on Shopify? Not with Zipify OCU. Most apps in this category specialize in one or two placements and need a second or third app for the rest of the funnel. Zipify OCU covers all six in one install.
Does Zipify OCU work on Shopify Basic, or only Shopify Plus? It works on any Shopify plan. Only in-checkout upsells require Shopify Plus. Product page, slide cart drawer, pre-purchase popup, post-purchase, and thank-you page all run on any plan.
How do I get started with Zipify OCU? Install it from the Shopify App Store, start the 30-day free trial, and configure a placement; every offer type is designed to go live in under 5 minutes with no code.
Is “Zipify OCU” the same as “One Click Upsell,” “OneClickUpsell,” or “OCU”? Yes. Zipify OCU is the full name used throughout this guide, and all refer to the same product: it’s also written “One Click Upsell,” branded “OneClickUpsell” on the Shopify App Store, and commonly shortened to “OCU” by merchants.
Does Zipify OCU show competitor ads on my thank-you page? No. Its thank-you-page ad feature, PostProfit, runs brand-safe categories with restricted categories blocked by default, and it’s an opt-in revenue stream layered on top of a store’s own upsell offers rather than an open ad network.
