You already made the sale. Now sell one more thing in a single tap, on any Shopify plan, in about 20 minutes. No developer. No theme files. No risk to your checkout.
Install a no-code post-purchase app, set it as your active app in Settings → Checkout → Post-purchase page, pick one add-on product, give it a small discount, and hit publish. That is the whole job. No theme edits. No code. Works on any Shopify plan. The offer shows after the customer pays, so it can never slow down or break your checkout.
You just got a sale. The buyer is happy. Their card is already charged.
This is the best moment to sell one more thing, and most stores walk right past it.
A post-purchase upsell is a small offer that pops up right after checkout. The shopper grabs it with one tap. No new card. No new form. It just gets added to the order they already placed.
The best part? You do not need to write a single line of code. You do not need a developer. And you do not need Shopify Plus. You can set the whole thing up yourself today.
This guide walks you through it in plain words. It also covers the parts most blogs skip, like where the offer really shows and why it sometimes does not show at all.
It is an offer a shopper sees right after they pay, before they land on the final "thank you" page.
Here is the trick that makes it special. The payment is already done. So the shopper does not need to type their card again. They just tap "Yes, add it," and the item joins the order they just placed.
Think of it like the candy rack at a checkout lane. You did not come for the gum. But it is right there, it is cheap, and you grab it. A post-purchase upsell is that candy rack for your store.
And no, this is not a popup in the cart. A cart popup shows up before someone buys, so a pushy one can scare them off. A post-purchase offer shows up after the sale is locked in. That one difference changes everything.
Most blogs say the offer lives "on the thank-you page." That is close, but not exact, and the real answer helps you set it up right.
Shopify gives apps a special spot called the post-purchase page. It loads after the shopper pays, but right before the order-confirmation (thank-you) page. That little page in between is where your one-click offer appears.
The thank-you page (Shopify also calls it the order status page) is a separate spot. You can add things there too, like a survey, a tracking link or a reorder button. But the one-tap offer itself lives on that post-purchase page in the middle.

A few years ago, adding an offer after checkout meant editing theme files or hiring a developer. That is over.
Today, Shopify lets trusted apps plug into the post-purchase page on their own. You do not touch your store's code. You just click buttons in an app.
Two things people get wrong, cleared up:
That is it. The app handles the hard part. You handle the offer.
Three simple reasons. Each one is on your side.
The scariest step in any sale is getting a stranger to trust you with their card. Your buyer just did that. Saying "yes" to a small add-on is easy after a big "yes."
The offer only loads after payment is taken. If the shopper ignores it, you still keep the first order. You cannot lose the sale. That makes this the safest spot in your whole store to make a bold offer.
One tap adds the item. No new checkout. No new shipping form. The easier the "yes," the more people say it.
That is also why a one-tap offer beats a "come back and buy again" email. The card is already on file, so there is nothing to stop the buyer in the moment. For real benchmarks on order value, Shopify keeps a solid primer on average order value.
Selling more to a buyer you already have is far cheaper than finding a brand-new one. A post-purchase offer squeezes more value out of traffic and ads you already paid for. Nothing else in your funnel is this cheap to add.
A little prep makes the setup smooth. Have these ready:
Start with one offer, not ten. One offer is easy to test and easy to read later. You can always add more once you see what works.
Choose a single add-on that pairs with your best seller. Keep it cheaper than the main order. A $90 order plus a $15 add-on is an easy yes. A second $90 item is a hard one.
Example: someone buys a coffee grinder, you offer a bag of beans.
Open the Shopify App Store and add a post-purchase upsell app. It installs in a click and opens inside your Shopify admin. No downloads, no theme editing, and it runs on any plan.
An all-in-one like Oxify Cart Drawer PostPurchase does the post-purchase offer plus a cart drawer, a thank-you-page editor, and free gifts, BOGO and volume discounts, all from one app.
Go to Settings → Checkout → Post-purchase page and pick your app. Shopify only lets one app run here, so this step tells Shopify which offer to show.
In the app, choose your add-on product. Then add a small one-time discount, like 10% or 15% off, that only works on this screen. A clear deal makes the offer worth a tap.
Skip the fancy words. Say what it is and why to grab it now. Something like: "Add the matching beans, 15% off, only on this page." Short beats clever.
Hit publish. Then buy something yourself with a real credit card so you see the offer the way a shopper does. (Wallets like Apple Pay won't trigger it, more on that below.) If it looks good, you are live.
Total time: about 20 minutes for your first offer.
This catches a lot of merchants off guard. Shopify only lets one app use the post-purchase page at a time. If you install two upsell apps, they cannot both show offers. You have to pick one in your checkout settings.
So that single slot is valuable. It pays to fill it with an app that does more than one thing.
This is the honest case for an all-in-one. Instead of one app for the post-purchase offer, another for a cart drawer, and a third for gifts and volume discounts, you can run a single app that covers all of it. That is the idea behind Oxify Cart Drawer PostPurchase: one app for upsells before and after checkout, so your one post-purchase slot is not wasted and your monthly bills are not stacked.
Already have an old post-purchase app you stopped using? Remove it, or your new offer may not appear. Only the app selected in Settings → Checkout → Post-purchase page will show.
Sell the thing that goes with what they bought. Phone case after a phone. Beans after a grinder.
They bought one. Offer the pair, the refill, or the next size. Easy to picture, easy to say yes to.
A cheap, fun extra under $20. Low price means a fast tap. Great for impulse buys.
"Buy 2 more, save 15%." Works well for things people reorder, like socks, snacks or skincare.
Offer the bigger size or the premium version at a one-time deal. Best for items with clear tiers.
Offer more of the exact item they just bought, at a small "stock up" discount. Simple and it works.
Keep it relevant. A helpful match feels like good service. A random bestseller feels like spam, and shoppers learn to ignore it. Want a swipe file? See our post-purchase upsell examples.
Here is the part almost no guide tells you. A one-click post-purchase offer needs a saved credit card to charge with a single tap. So Shopify hides the offer on some orders. This is normal, not a bug.
Your offer will not show when the order uses:
One more limit: a shopper can accept at most two post-purchase offers per order. So do not plan a long chain of ten.
If most of your sales are cash on delivery, the one-click offer simply will not fire. There are still smart ways to raise order value on those orders. We cover them in post-purchase upsells for COD stores.
Most weak results come from these. Dodge them and you are ahead of most stores.
You do not need a spreadsheet. Watch two simple numbers in your app's dashboard:
Give it a couple of weeks and enough orders before you judge it. Then change one thing at a time, the product or the discount, so you know what moved the needle. Small wins add up fast over a month.
Results change by store, product and offer. Do not chase someone else's number from a blog. Run your own offer, watch your own dashboard, and let your store tell you the truth.
Right, you don't. A no-code app does the work. You pick a product, set a discount, type one line and click publish. There is no theme editing and no developer.
No. Post-purchase apps from the Shopify App Store work on Basic Shopify and up. Plus is only needed to build a custom-coded app or to edit the checkout page itself.
On a dedicated post-purchase page that loads after the customer pays, but before the final thank-you (order status) page. The card is already on file, so they can accept with one tap.
No. The offer only loads after payment is taken. It cannot slow your checkout or lose the sale. If the buyer says no, their first order is untouched.
Some orders can't show it: cash on delivery, gift cards, wallets like Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm and Afterpay, a few gateways such as Braintree and PayPal Payments Pro, plus orders with duties, multiple currencies or local delivery. Also, only one post-purchase app can be active at a time.
No. Shopify lets only one app run on the post-purchase page. If you install more than one, choose the active app in Settings, Checkout, Post-purchase page.
About 20 minutes for your first offer, less once you have done one. Templates make it even faster.
It depends on your product, offer and shoppers. A relevant one-tap offer often lifts average order value, but test your own offer instead of trusting one benchmark.
