Mastering Shopify Upsells: Where, What, and How to Grow Your Average Order Value

Hey everyone! As a Shopify migration expert, I spend a lot of time digging into what makes stores tick. Recently, I jumped into a fantastic community discussion that started with a simple, yet powerful question from bjornson: "What are the best upsell apps and features for a Shopify store?"

Bjornson noticed competitors using clever upsell tactics and wanted to explore how to implement them. This sparked a really insightful conversation, especially relevant for stores like bjornson's, which sells women's clothing with an AOV of around $30-50. Let's break down the goldmine of advice shared by fellow store owners and app developers.

Beyond the Pop-Up: The Strategic 'Where' of Upselling

One of the biggest takeaways from the discussion was that placement often matters more than the specific app you choose. It's not about throwing offers everywhere; it's about making them feel helpful and natural to your customers. As Easify-Jennifer wisely put it, "I'd focus on the ones that feel helpful to customers rather than adding offers everywhere."

Understanding Your Placement Options (and Limitations):

• Product Page & Cart Offers: These are your classic "frequently bought together" or "add-on" suggestions. They work on any Shopify plan and can be highly effective. Ellie-BOGOS shared some great visuals for these, like a "Product Add-on" directly on the page or "Frequently Bought Together" sections. The key here is relevance.
• Checkout Page Upsells: This is where things get a bit tricky. As lumine and Bristan_FARRE clarified, offers directly within the information, shipping, or payment steps of the checkout are Shopify Plus only. If you're not on Plus (like bjornson), apps advertising "checkout upsells" are usually referring to the thank-you page.
• Post-Purchase Offers: These are those slick, one-click offers that appear immediately after a customer pays but before they reach the final thank-you page. They're compelling because the customer has already committed to the main purchase, so there's no risk of losing the original sale. Bristan_FARRE highlighted this as a "safest one to test first." However, there's a catch: lumine pointed out that Shopify skips this page for certain payment methods like wallet services (Apple Pay, Shop Pay, Google Pay) or installment plans (Klarna, Afterpay). So, if a large percentage of your customers use these, a post-purchase-only strategy might miss a lot of orders.
• The Thank-You Page: This page is a hidden gem! UprightApps emphasized that since the customer has already paid, an offer here can't cost you the sale. Crucially, it renders for every order, including those that skip the post-purchase page due to wallet payments. It might be a second, separate order, leading to a slightly lower acceptance rate than a one-click post-purchase offer, but it's incredibly safe and broad-reaching. For bjornson, with 10-20% express checkout share, a thank-you page offer would still reach a large majority of customers.
• The Forgotten Search Bar: Nicole_Kimonix brought up a brilliant, often-skipped surface: the search bar. "Someone who types into your search bar has told you exactly what they want. That’s higher intent than anyone sitting in the cart, and it’s the one place a suggestion doesn’t feel like an interruption." Recommendations within search results, or a search experience that can answer "what goes with this," can be incredibly powerful.

The 'What': Crafting Offers That Convert (and Profit!)

It's not just about where you show the offer, but what you're offering. The community shared some excellent insights:

• Complementary Products & Bundles: Easify-Jennifer listed accessories, refills, matching items, and natural bundles as top performers. Ananya0 suggested starting with "frequently bought together" or related products.
• Volume Discounts: "Buy 2, Save 10%; Buy 3, Save 15%" is a classic for a reason.
• Value-Adds: Gift wrap, premium packaging, rush processing, or warranties can be easy add-ons.
• Free Shipping Thresholds: A simple, effective nudge to add one more item to reach a free shipping minimum.

Crucial Considerations for Offer Logic:

Nicole_Kimonix dropped some serious wisdom here, especially for fashion stores like bjornson's:

• Size Availability: "The classic killer is recommending a piece that’s technically in stock but gone in most sizes." If a customer clicks an upsell only to find their size missing, you've wasted their attention. Weighting recommendations by how complete the size run is can dramatically improve conversion.
• Margin: Many upsell tools optimize for acceptance rate, which can push cheap or discounted products, potentially lowering your overall profit even if attributed revenue looks good. If your app allows it, feed cost data into the logic to ensure you're recommending profitable items.

Also, remember the advice from UprightApps: aim for one offer, not a carousel, especially on the thank-you page. And set a cap on how often one customer sees a particular offer to avoid fatigue.

Smart Testing: Don't Just Install & Pray

The community universally agreed: start small and measure everything. "Turn on four at once and you won’t be able to tell which one earned anything," warned Bristan_FARRE.

1. Pick One Placement & One Offer: Start with a single, highly relevant offer in one strategic location (e.g., a complementary item on the thank-you page).

2. Establish a Baseline: Before you turn anything on, know your current average order value (AOV).

3. Measure Beyond AOV: Binaery suggested tracking "attach rate and revenue per session (or contribution after discounts/shipping)" to get a clearer picture of profitability, not just raw AOV. Don't let a "louder cart drawer" mask a drop in overall conversion.

4. Run for Two Weeks: Give your test enough time to gather meaningful data.

5. Iterate: Only then consider adding a second surface or modifying your offer.

A Quick Check Before Installing Any App:

UprightApps shared some fantastic tips for checking how an app integrates, which is crucial for store performance and cleanliness:

1. App Store Listing: Look at the "Works with" row. If it lists "Checkout," the app likely uses Shopify's modern Checkout UI extensions. If it's missing or lists only "Shopify Flow," it might be storefront-only.

2. Thank You Page Check (after installing): Go to Settings > Checkout > Customize, open the Thank you page in the editor, then click Apps in the left sidebar and the Added tab. If the app renders via extensions, you'll see a block there.

3. Storefront Script Tag Check: On any product page, type view-source: in front of the URL. Search for asyncLoad. Shopify loads app scripts via this function, and the URLs next to it will show the app's domains. This tells you if the app injects script tags. (Note: script tags don't run on checkout or thank-you pages anymore since the Aug 26 cutoff, so this check is for product and cart pages).

Apps to Explore (with Community Mentions):

While the strategy is paramount, several apps were mentioned that can help implement these ideas:

• For Product Page & Bundles:
  • Easify Custom Product Options (for add-ons, personalization, volume discounts directly on PDP)
  • Peakify Upsell Bundles (quantity breaks, bundles, mix & match, related products)
  • CrossSell (various upsell/cross-sell placements)
  • BOGOS: Free Gift Bundle Upsell (product add-ons, FBT, cart recs, thank-you page – has a free plan)
• For Post-Purchase & Thank-You Page:
  • Sellify (post-purchase, product page, checkout (Plus), thank-you page – free on App Store)
  • Upright Upsell (specializes in thank-you page offers)
• For Unique Notification-Based Offers:
  • Atomato (shopper-opened notification bell/feed for offers, restocks, drops – a quieter, secondary path)

Here are some visual examples of different upsell types shared by Ellie-BOGOS:

• Product Add-on

• Frequently Bought Together

• Product recommendation in cart page or cart drawer

• Checkout upsell (Shopify Plus only)

• Thank you page upsell

• You can also upsell customers a complimentary bundle under the product page like this

Ultimately, the best upsell strategy for your Shopify store, whether you're selling women's clothing like bjornson or something entirely different, comes down to understanding your customer journey, strategically choosing your offer placements, crafting genuinely helpful and profitable offers, and rigorously testing your results. Don't be afraid to start small, measure diligently, and iterate based on what your customers tell you through their purchasing behavior. Happy upselling!
