You know when you are ready to check out and very gracefully your cart slides out and below your order you see product suggestions with “Add to cart” or “Upgrade to a subscription?” 

Well, that's a cross-sell or upsell at work! And they work! Increasing your average order value, and often your profit margins, in the process.

One important distinction, even though these two terms are often used synonymously (and we will largely just stick with “upsell” as we talk about this process), they are different:

Upsell: Upgrading a product to a larger quantity (i.e. 8 ounces to 16 ounces)

Cross-sell: Add on a complimentary product (i.e. a coffee cup when ordering coffee)


Important Metrics to Track:

  • % of orders upsold/cross-sold
  • % of orders upgraded to a subscription (if applicable)
  • Breakdown of successful upsells by product
  • Overall Average Order Value (AOV) lift
  • Overall Revenue lift

Note: Upsells and Cross-Sells are often part of a broader merchandising or personalization strategy, to check out full-fledged AI personalization tools/suites in more detail, go to our blog post on The Best Personalization Tools for Ecommerce. Keep reading for a deeper outline of the apps that have more of a hyper-focus on upselling than personalization.

Why are Upsells so Important?

For starters, it allows you to increase your average order value while also promoting greater product exploration and discovery. The more products you can get into your customers hands, the better.

If a site visitor was only coming to your site to purchase one thing, they probably are not looking at other products. However, if you take that same visitor and place additional products on pages like the product detail page and cart page, based on what they are looking at/purchasing (cross-sell), it has the potential to catch their eye and allow them to further explore your site, products, and brand as a whole.

Integrating upsells and cross-sells onto your site should be a no-brainer. This is high revenue-driving, low-hanging fruit. And the revenue impact is two-fold: not only do you receive additional revenue on that first order, but the recurring orders tend to be higher as well.

Worried about upsells hurting your conversions? Post-purchase offers are a great way to utilize upsell/cross-sell strategies to see an uptick in average order sales. This way you don't have to worry about the potential of losing a conversion since it already happened.

When Should you Upsell? (Hint: Pre- and Post-Purchase Options)

This is completely up to you, your customers, and hopefully the tests you run in perfecting your upsell process. It is really never too early to incorporate upsell. I would even argue that this should be something you consider at the onset of your company, as it becomes customary on your site and a cornerstone of your marketing and growth strategy.

By far the easiest, and most common upsell is a subscription program. Most brands have a product that can easily fit into a subscription model. If that's not your product, no need to fret because not all subscription models are created the same (but their benefits are!). Anything you sell can fit into a subscription model whether it's food, beauty products, sunglasses, or phone cases, you just have to find the model that works best for you and your subscribers. 

Additionally, you need to have multiple products and/or product lines to really be successful with upselling. I’ve seen some one-product brands really stagnate around this problem while they build out complementary products (or source them). If you only have one core product or a very low SKU count altogether, you should spend some time thinking about what product you can really add to your mix that is likely to be popular with your customers. In the beginning it doesn’t even have to be your product, you can test complementary brands using a tool like Carro Brand Partnerships, and use the learnings from selling those products to inform your own internal product strategy.

Upsells in Practice

The key is to be strategic and ensure that you are adding value to the user journey and not just randomly placing pop-ups or irrelevant offers in front of customers who are presumably about to buy from you. 

Here are the most common areas you see upsells and how they are used:


  • Home Page
  • Product Detail Page (PDP)
  • Cart slide out
  • Cart page 
  • Checkout page 

Post Purchase

  • Post-purchase click offer 
  • Email/SMS
  • Order Tracking Landing Pages
  • Reorder Landing Pages

You also can see upsells in emails (or SMS), as bundled offers, as subscriptions, in use with Buy Now Pay Later (BNPL) solutions, and even as part of your customer service teams communications with customers (more commonly, you may see some sort of downsell offer to say prevent a refund).

Use Cases: 

  • Product Detail Page (PDP): subscription upsell above/below where the one-time purchase option is + towards the end of your page (common language = “You May Also Like”).
  • Cart Slide Out: Subscription upsell or one-time add-ons.
  • Cart Page: “You May Also Like” products.
  • Checkout page: Dynamic add-ons based on products in cart.
  • Post-purchase: Before order confirmation provide a 1-click upsell that will append to the customer’s existing order.
  • Communication: Utilize previous order data to communicate “Suggested Products”/”Because You Bought ‘A’” 
  • Order Tracking Landing Pages: Manual based on strategic decisions or utilize AI suggestions  

The Best Upsell/Cross-sell Tools for Ecommerce

Thanks to app designers and ecosystems like Shopify, the ability to implement programs for upsells/cross-sells has become easier than ever. 

Rather than spending hundreds of hours (and dollars) on a developer, you can easily search for a tool that is all queued up to do this job for you - and we have just so happen to have a few recommendations. 

Note: always consider your options and what works best for your store, as well as the other tools you are currently utilizing. Everything in your store should have a purpose and contribute to your greater goals.

‍Thank-you Page Optimization for Upsells & Cross-sells

Upsells are part of the package, of course, but with additional functionality around birthdays, social shares, and videos & imagery, ReConvert gives store owners considerably more creative latitude over their thank-you pages – in far less time than rolling your own code.


  • Social sharing widget on thank you page

Transactional Optimization Platform

If you’re not leveraging Shopify’s existing transactional emails, then you should be.

Spently allows businesses, both small and large, to leverage their notification emails within Shopify with marketing components. Most importantly, you can turn your most important emails, tracking notification emails (among others) into marketing collateral for cross-sells and upsells.


  • Optimize notifications emails with event-based upsells, personalized discounts and referral components

All plans are based on total monthly orders.

For businesses generating 500 orders or less per month, Spently’s Essential Starter plan is $99/month and allows for follow-up emails, personalized discounts, referrals and integration with Limespot, Kit and Sufio (which is not available in the Starter plan).

Pricing goes up from there.

Carro Brand Partnerships

Merchandising Complementary Products for You to Upsell/Cross-sell

While Carro doesn’t necessarily help with displaying your offers, they do help you find great products that you can offer on your site, which makes them a perfect partner tool to many of the tools listed here.

It starts by installing their tool and browsing their massive library of other Shopify brands looking to cross-promote/cross-sell their products. Find the dog leggings that go perfectly with your dog sweater, for example.

Once you’ve loaded that product to your site, figure out how to offer it in a bundle, as a cross-sell on your cart page, or wherever else it seems fitting.

And watch the revenue come in.

They do have a free plan available for merchants doing under $5,000/month in revenue, but you’re going to want the power of at least their $20/month program, which gives you access to email personalization, deeper integrations, and better split testing. They do have enterprise plans and more advanced feature opportunities as well.
