The short answer
- Shopify upsells run in five places: the product page, the cart or cart drawer, the checkout, the post-purchase page and email after the order.
- Shopify's own tools cover more than most stores use: Shopify Bundles for fixed bundles and multipacks, Search & Discovery for complementary products, and a Shopify Messaging automation that upsells after a first purchase.
- Post-purchase offers through apps work on Basic and up. Offers inside the information, shipping and payment steps of checkout are Shopify Plus only.
- Judge every upsell on margin per order, not average order value alone. A discount that lifts AOV can still lower profit.
Upselling is the cheapest growth a Shopify store has. The customer is already buying, the ad is already paid for, and every extra dollar in the basket lowers the effective cost of acquiring that order. This guide covers the placements, what Shopify does natively against what needs an app, and a worked example of the AOV and margin math.
Upsell, cross-sell and bundle: the difference
| Tactic | What it offers | Example | Best placement |
|---|---|---|---|
| Upsell | A better or bigger version of the same item | 500ml instead of 250ml; the leather version | Product page |
| Cross-sell | A complementary item | Case with a phone; filters with a coffee machine | Cart drawer, post-purchase |
| Bundle | Several items at one price | Shampoo, conditioner and mask set | Product page, collection |
| Multipack | More of the same item | 3 pairs of socks for the price of 2.5 | Product page |
| Threshold offer | A reward for spending more | Free shipping over $60 | Cart |
The five placements, and what Shopify offers natively
| Placement | Shopify native option | Needs an app or Plus? | Typical offer |
|---|---|---|---|
| Product page | Shopify Bundles (fixed bundles, multipacks); Search & Discovery complementary products | No; both are Shopify apps listed as free | Bundle or bigger size |
| Cart or cart drawer | Theme cart and cart drawer | Usually an app for add-on offers in the drawer | One low-price add-on; free shipping bar |
| Checkout steps | Checkout UI extensions in information, shipping and payment | Shopify Plus only | One add-on before payment |
| Post-purchase page | Post-purchase app extensions | Any app using them; Basic plan and up | One-click add-on after payment |
| Thank you and order status pages | Checkout Blocks content blocks; UI extensions | Basic plan and up | Next-order discount, referral |
| Email after purchase | Shopify Messaging "Upsell customers after their first purchase" automation | No | Complementary product at the right reorder time |

Product page
The product page is where bundles and size upgrades sell best, because the shopper is still choosing. Shopify Bundles creates fixed bundles and multipacks from the admin, lets shoppers pick variants inside the bundle, and keeps inventory in sync so a bundle never oversells a component. Show the saving in money, not percent, when the item price is under $50.
Cart and cart drawer
The cart is for small, obvious add-ons. Keep it to one or two offers priced well under the cart value. A $9 accessory on a $60 cart is an easy yes; a second $60 item is a new decision that slows checkout. A free shipping progress bar belongs here too: set the threshold about 20% to 30% above your current AOV so it is reachable with one add-on.
Checkout and post-purchase
On Plus, an offer can sit inside checkout before payment. On every other plan, the strongest equivalent is the post-purchase page: after payment, before the thank you page, an app shows one offer the customer can add with one click, without re-entering card details. Because the first order is already safe, a post-purchase offer cannot cost you the original sale. That makes it the lowest-risk upsell on Shopify.
Basic plan stores can also use Checkout Blocks content blocks on the thank you and order status pages, for a next-order discount or referral offer. The other Checkout Blocks features are Plus only.
Email after purchase
Some cross-sells need time. A customer buys a coffee machine today and needs descaler in two months. Shopify Messaging's "Upsell customers after their first purchase" automation handles this; the timing and the rest of the flows are in Shopify email marketing.
AOV math: a worked example
A store does 1,000 orders a month at a $60 average order value, with a 50% gross margin. Revenue is $60,000 and gross profit $30,000. It adds three upsells:
| Upsell | Offer | Take rate | Added revenue | Added gross profit |
|---|---|---|---|---|
| Cart add-on | $12 accessory, 60% margin | 10% of orders (100) | $1,200 | $720 |
| Post-purchase offer | $25 refill at 15% off ($21.25), 50% margin before discount | 6% of orders (60) | $1,275 | $525 |
| Bundle on product page | Two-item bundle at $108 instead of $120 | 15% of orders switch (150) from $60 to $108 | $7,200 | $2,700 |
| Total | $9,675 | $3,945 |
AOV rises from $60 to $69.68, up 16%. Gross profit rises from $30,000 to $33,945, up 13%. The gap between those two numbers is the discount cost: the bundle gives away $12 on each of 150 orders, and the post-purchase offer $3.75 on each of 60.
How the profit lines work. Each item costs the store $30. The bundle sells two for $108, so it earns $48 of profit against $30 on a single $60 item: $18 more per switching order, or $2,700. The post-purchase refill earns $21.25 less 50% of its $25 list value in cost, $12.50, leaving $8.75. Check your own numbers this way before running an offer with a discount.
What it does to your ad budget
If the store pays $30 to acquire an order, a $60 order returns a ROAS of 2.0. At $69.68 the same $30 returns 2.32. Every ad campaign clears its target more easily, and campaigns that were just below break-even become profitable without any change to the ads. Find your break-even with the ROAS calculator.
Rules that keep upsells from hurting conversion
- One offer per placement. A cart with four suggestions is a page of decisions.
- Relevant beats cheap. The complementary item for that product, not the store's best seller shown on every page.
- Price add-ons well below the main item. Under about 25% of the cart value is an impulse; above it is a second purchase decision.
- Never interrupt checkout on mobile with a pop-up. Use inline blocks or the post-purchase page instead.
- Watch conversion rate, not just AOV. If conversion falls when an upsell goes live, the upsell is costing more than it earns. The baseline numbers are in Shopify conversion rate optimization.
- Test the app on a phone before launch. Upsell apps that inject scripts into the cart are a common cause of slow or broken carts.
Using ads to cross-sell past buyers
Some cross-sells sell better as ads than as on-site offers. Upload last quarter's buyers of product A as a customer list audience on Meta, and show them catalog ads for product B. It works best when B is a clear companion to A and the gap between purchases is weeks, not minutes. The setup for catalog ads is in Shopify Facebook ads.
Where Sprites fits
Sprites does not install upsell apps or change prices. It works around them: it builds Meta customer list audiences and catalog ads that cross-sell past buyers, writes the copy for bundle product pages, and publishes "complete the set" collection pages into the store as drafts for your approval. See Sprites for Shopify and pricing.
FAQ
How do I add upsells to my Shopify store?
Start with Shopify's own apps: Shopify Bundles for fixed bundles and multipacks on product pages, and Search & Discovery for complementary product recommendations. Add a post-purchase upsell app for one-click offers after payment, and turn on the Shopify Messaging automation that upsells customers after their first purchase.
Does Shopify have a built-in upsell feature?
Partly. Shopify Bundles, Search & Discovery and Shopify Messaging are Shopify-built and cover bundles, complementary products and post-purchase emails. Cart drawer offers and post-purchase page offers usually need a third-party app, and offers inside the checkout steps need Shopify Plus.
Can I add upsells to Shopify checkout without Shopify Plus?
Not inside the information, shipping and payment steps; apps that customize those pages are Shopify Plus only. On the Basic plan and up you can use post-purchase app extensions, which show an offer after payment, and content on the thank you and order status pages.
What is a post-purchase upsell on Shopify?
It is an offer shown after the customer pays and before the thank you page, which they can add with one click without re-entering payment details. Because the original order is already complete, it cannot cost you the first sale. It runs through apps built on post-purchase extensions, available on Basic and up.
How much can upsells increase average order value?
It depends on the offer and take rate. In a worked example of 1,000 orders at $60, a cart add-on, a post-purchase offer and a bundle together raised AOV by about 16% and gross profit by about 13%. Always check the profit effect, because discounts lift AOV faster than profit.
Is the Shopify Bundles app free?
Shopify Bundles is listed as free on the Shopify App Store and is built by Shopify. It creates fixed bundles and multipacks from the admin, lets customers choose variants inside a bundle, and updates inventory in real time to prevent overselling.
