Cheap add-ons that complete the product
- It feels like the missing piece they almost forgot.
- It's small, so it's an easy impulse buy.
- It makes the main product work better, so it helps the customer too.
The customer already paid. Now Shopify can show them one last offer. Put the right product there and your order value climbs — with no extra ad spend. Here are the product types that win, the data behind them, and real examples you can copy today.
The best post-purchase upsell is a cheap product that matches what the buyer just bought and feels like an easy "yes" — think batteries with a toy, beans with a coffee maker, or a warranty with a laptop. The top picks are complementary add-ons, refills, warranties, complete-the-set bundles and gift wrap. If you remember one rule: offer a small, relevant add-on, not a second big purchase.
Benchmarks are commonly reported industry ranges and vary by store; the 310 Nutrition result is from Shopify's own reporting. Always test your own offers.
A post-purchase upsell is the offer a shopper sees right after they hit "Pay now." The order is already done. The card is already charged. So they can add one more thing with a single tap — no new checkout, no typing their card again.
That makes it the safest place in your store to make an offer. Say no, and you still keep the full order. Say yes, and you just grew the sale for free.
But the product you put there decides everything. The wrong pick gets ignored. The right pick can lift your average order value (the average amount people spend per order) without spending a cent more on ads.
If you only fix one thing, fix this. The offer has to match what the buyer just got.
The numbers are clear. A typical after-checkout offer is taken by about 4 in 100 buyers. But a relevant offer — one that clearly goes with the order — converts several times higher than a random "bestseller." Same traffic, same slot, very different results.
Why? Because a matching add-on feels helpful, not pushy. Beans with a coffee maker make sense. A random scarf does not. So before anything else, make the offer fit.
On top of relevance, every winning offer follows three quick rules:
Before the full list, here's a simple way to think about it. Almost every winning post-purchase product is one of three types:
Keep these three in mind. The 8 product types below are just the most useful, real-world versions of them.
You don't have to take our word for it. Here's what real stores and benchmarks show.
Now picture it in action. Say Maya sells coffee makers, and her best seller is $90.
For months her after-checkout offer was a $120 espresso machine. Almost nobody clicked — it cost more than the order they just made.
So she swapped it for a $14 bag of fresh beans, 15% off, only on this page. Now it matched the rules: cheap, related, and an easy yes. Buyers started adding the beans. Same traffic. Same ad spend. Bigger orders.
The lesson: the product matters more than the app. Pick a small, matching add-on and the offer starts working on its own.
| If you sell… | Offer this after checkout | Why |
|---|---|---|
| Coffee makers | Beans, filters, descaler | They'll need them soon |
| Phones & electronics | Case, screen protector, warranty | Cheap, protects the buy |
| Skincare | Matching serum or travel size | Completes the routine |
| Clothing | Care kit, matching accessory, gift wrap | No size to re-pick |
| Pet supplies | Treats, refill food, subscription | Repeat buys |
| Supplements | 2nd bottle at a discount | Stock-up impulse |
| Candles & home | Matching scent or gift set | Easy add-on |
| Courses & digital | Bonus guide or template pack | No shipping, high margin |
Use this as a starting point, then test your own ideas. Your customers will always tell you what works best through their clicks.
The pattern is clear. Good upsells keep the moment simple, cheap, and profitable. Bad ones ask the buyer to stop and think again — and thinking is the enemy of a one-click offer. Skip low-margin products too: if you can't give a small discount and still make money, the offer isn't worth the slot.
You don't need fancy data. Just follow these five steps and you'll land a strong offer fast.
Once your first offer works, don't stop at one. Make a quick map so every order gets a smart offer:
That's it. A one-page map turns a single offer into a system that grows order value across your whole store.
Picking the product is the hard part. Setting it up is easy — but you do need an app, because Shopify can't build these offers on its own.
A good upsell app lets you:
Many stores end up buying three or four apps for this — one for upsells, one for bundles, one for gifts, one for the cart. Our app, Oxify Cart Drawer PostPurchase, puts the whole toolkit in one place: post-purchase upsells, a thank-you-page editor, a slide-out cart drawer, frequently-bought-together bundles, free gifts, BOGO, volume discounts, subscriptions and countdown timers. So every product type in this guide — the bundles, the "buy another," the subscriptions, the gift add-ons — can be set up from one dashboard.
It's Built for Shopify, rated 5.0, works on every Shopify plan (no Plus required), and starts at $19.99/month with a 14-day free trial. If you'd rather compare options first, see our guide to the best Shopify post-purchase upsell apps or browse more real upsell examples.
Most weak results come from a few simple slip-ups:
Cheap, matching add-ons. The top picks are small accessories that complete the main product, refills and consumables, warranties or protection plans, complete-the-set bundles, and gift wrap. They're all low-price, clearly related, and an easy one-click yes.
Complementary products usually win after checkout, because the buyer already chose the version they want. Replenishment (refills and consumables) is a close second for repeat-buy products. Upgrades to a bigger or pricier version convert less here — save those for the cart.
Keep it well below the order they just placed — a good rule is no more than about a quarter to a third of the total. A small add-on feels tiny next to what they already spent, so it converts better.
A typical take rate is around 4 in 100 buyers, but well-targeted, relevant offers can reach 10–15% or more. Relevance is the biggest lever — matching offers convert several times higher than random ones. Test your own offers, since results vary by store.
Avoid items that cost more than the order, random bestsellers that don't match, low-margin products that can't absorb a discount, anything that needs a size or color choice, items with high return rates, and heavy or bulky products with big shipping.
Just one strong offer. The power of this slot is its simplicity — one click, one yes-or-no. If your app supports a funnel, a single follow-up offer is fine, but never stack a wall of choices.
No. The offer shows up after payment is captured, so it can't slow down or risk the original order. If the buyer says no, you keep the full sale — which is exactly why post-purchase is the safest place to make an offer.
