Shopify checkout upsells.
Every placement, on every plan.

What a checkout upsell actually is.

"Checkout upsell" covers two different mechanics, and the difference matters more than most guides let on:

• A pre-purchase offer — the order bump. A small add-on presented before the customer pays: a checkbox or tile in the checkout offering a warranty, a refill, a matching accessory. If they take it, it joins the same order and the same charge. Because it sits between the customer and the Pay button, it has to be light — one glance, one tap, no second thoughts.
• A post-purchase offer — the one-click upsell. An offer shown after the order is confirmed but before the thank-you page. The sale is already safe, and payment details are already captured — so the customer can accept with a single click, without re-entering a card. That safety is what lets you make a bigger swing here: a second unit, an upgrade, a bundle.

Done with relevant offers, upsells can raise average order value without adding a cent of ad spend — you're selling to someone who already said yes. The catch on Shopify is that where you're allowed to make these offers is gated by plan, which is what the next section maps.

Where Shopify lets you upsell, by placement.

Working through the funnel from first click to thank-you page:

Product page and cart — any plan

Cross-sells and "frequently bought together" blocks on product pages and in the cart live in your theme and apps, not the checkout, so no plan gate applies. They're the earliest and least intrusive placements — and the ones your customer is most likely to scroll past.

Inside the checkout steps — Shopify Plus only

Offers on the information, shipping, and payment pages — where a true pre-purchase order bump wants to live — are built with checkout UI extensions. Shopify's docs are unambiguous: extensions that render on these steps "are available only to stores on a Shopify Plus plan."^1,2 On Basic, Grow, or Advanced, no app can put an offer inside the checkout form itself, because the platform doesn't allow it. Shopify publishes Plus at $2,300 USD/month on a 3-year term.⁶

Post-purchase — standard plans, with conditions

The post-purchase page renders after the order is confirmed but before the thank-you page — the classic one-click upsell slot.³ It's built on a separate extension type that doesn't carry the Plus gate, but it has conditions of its own: the customer's credit card must be vaulted before the offer can display, and when the conditions aren't met the offer simply never renders — the customer goes straight to the thank-you page.³ Apps also need Shopify's approval to run post-purchase extensions on live stores.³

Thank you and Order status pages — any plan except Starter

The pages after the purchase are the most broadly extensible: Shopify makes Thank you and Order status extensions "available to all plans except Shopify Starter."¹ This is where surveys, reorder prompts, and follow-on offers live on standard plans.

The Shopify checkout upsell app route.

Search "upsell" in the Shopify App Store and you'll find a long shelf of apps. We're not going to rank them — the honest version of this section is about what the category can and can't do, because every app in it operates inside the same platform rules from section 02.

What apps do well:

• Fast to try. Install, pick products, publish an offer — usually the same afternoon, no developer required.
• Placement coverage where the platform allows it. Product page, cart, post-purchase, and thank-you page offers all work on standard plans.
• Targeting logic. Good apps let you match the offer to what's in the cart instead of blasting one offer at everyone.

Where the route strains:

• The plan gate doesn't move. No app can place an offer inside the checkout steps on a standard plan — that capability is Plus-only at the platform level.^1,2 An app can only work with the slots Shopify opens.
• Conditional rendering. Post-purchase offers only show when Shopify's conditions are met — a vaulted card, an eligible order — so a slice of your buyers never sees the offer at all.³
• Stacking costs and stacking vendors. Upsells here, bundles there, a thank-you page app on top: each is a separate subscription, a separate dashboard, and a separate thing that can break on a checkout you don't control.

If you're on a standard plan and want to test whether upsells work for your store, an app on the post-purchase slot is a reasonable first experiment. If upsells become core to your economics, the ceiling starts to matter.

Own the checkout.
Upsells stop being an app.

The third path skips the plan gate entirely: keep Shopify as your storefront and catalog, and run your own checkout layer in front of the payment step. This is what Admoji does.

Your customers browse the same Shopify storefront. At checkout, they land on an Admoji checkout on your own domain — like checkout.yourdomain.com — while products, orders, and customers sync with Shopify.⁷ And because the checkout is yours, every upsell placement from section 02 is simply available:

• Order bumps in the purchase flow — pre-purchase offers next to the Pay button, the placement that's Plus-only inside Shopify.⁷
• One-click upsells built into the checkout — not a separate app bolted onto someone else's flow, but part of a checkout designed for conversion, with smart routing and retry logic baked in.⁷
• One system, one dashboard — the upsells report into the same CRM that holds your customers, subscriptions, and funnel data, so you can see true take rates instead of stitching together three apps' analytics.⁷

Pricing is published: $79/mo + 0.35% of volume on the Launch plan, no long-term contracts, with a 14-day free trial and no credit card required.⁷ The trade-off is architectural, not financial: you're adding a second system that syncs with your store rather than toggling a setting inside it. For a store where upsells are a side experiment, that's overkill. For a store where AOV is the growth lever, it's the difference between renting placements and owning them.

Upsells that help.
Not upsells that annoy.

Placement is only half the job. A badly chosen offer in a perfect slot still costs you trust, and trust is the thing the whole checkout runs on. The rules that hold up:

• Relevance beats aggression. The best-performing offer is the one that makes the customer think "oh, right, I do need that" — the filter for the machine, the second pair for the partner. An unrelated product at a discount reads as a shakedown.
• Match the weight to the moment. Pre-purchase bumps should be low-consideration: cheap relative to the cart, instantly understood. Save the bigger swing — the upgrade, the bundle — for post-purchase, where a "no" can't cost you the original sale.
• One good offer beats three mediocre ones. Every additional interruption between decision and confirmation is a chance to lose the order. If you wouldn't stack three popups on your product page, don't stack three offers on your checkout.
• Never make "no" feel like a trap. Declining should be one obvious click. Dark-pattern decline buttons ("No, I hate saving money") juice one metric and quietly poison repeat purchase.
• Measure take rate, then prune. An offer almost nobody accepts isn't neutral — it's friction. Watch which offers get taken and cut the rest.
